commelina diffusa control

The first verified resistance was registered in 1957, when C. diffusa biotypes were identified in the United States [26]. In Uganda, it was reported that heaping of stubborn weeds of Commelina plants is practical during the rainy season to speed up rotting and reduce the frequency of weeding [48]. Such combinations should provide significant management levels of Commelina species for both conventional as well as organic growers using a pesticide free production PFP approach. Nombres 2. Liriomyza commelinae (Diptera: Agromyzidae), a leaf-miner, was however reported on C. diffusa in Jamaica [20, 61]. Honolulu, Hawaii, USA: University Press of Hawaii. f. produced significant (p<0.001, p<0.01, p<0.05, p<0.02 and p<0.5) inhibitory activity … Stroud A, Parker C, 1989. Melon (Colocynthis citrullus L.) planted at a density of 5,000 plants/ha suppressed weed growth of Commelina diffusa for five months, enhancing establishment and yield of melon in Nigeria [49]. The plant is also a collateral host of Helicotylenchus dihystera infecting guava … 6 (Special Issue No. Weed Research, Japan, 19:20-24. Benghal dayflower was first observed in the early 1990s by both university researchers and crop producers, but was only found in limited areas. Publishing on IntechOpen allows authors to earn citations and find new collaborators, meaning more people see your work not only from your own field of study, but from other related fields too. Malaysia: 11 pp. The results indicated that, as for C. benghalensis, mesotrione, lactofen, oxyfluorfen, clomazone and flumioxazin provide complete control (100%), oxadiazon, fomesafen, metribuzin, acifluorfen, isoproturon, MCPA-sodium, carfentrazone-ethyl, fluroxypyr, fluoroglycofen-ethyl and bentazone are herbicides with excellent activity (90.0 - 100% control), paraquat, 2,4-D butylate, rimsulfuron and thifensulfuron-methyl are herbicides with good activity (80.0 - 90.0% control), and nicosulfuron, bensulfuron-methyl, dicamba and glyphosate-isopropylammonium are relatively ineffective (< 80.0% control) at their own recommended dose, respectively. Its flowers are usually bright blue and have rounded petals. Bissea: Boletín sobre Conservación de Plantas del Jardín Botánico Nacional de Cuba. This weed was in fact listed as a Federal Noxious weed in Florida and Georgia where it is the most troublesome weed in cotton and a pest in peanut, corn (Zea mays), soybean (Glycine max), nursery stock and orchards [81]. East African Weeds and their Control. Burnout® (concentrated vinegar and acetic acid) (20%), urea (20%), and fertilizer solution (20%) were also used to evaluate their efficacy on the control of Commelina species and other weed species. C. Commelina diffusa; Media in category "Commelina diffusa" The following 42 files are in this category, out of 42 total. Best results were obtained from Desmodium heterocarpon (86.7%) followed by Arachis pintoi (52.1%) and Mucuna pruriens (43.3%). [25]. [1] Die Gattung Commelina gehört zur Tribus Commelineae in der Unterfamilie der Commelinoideae innerhalb der Familie der Commelinaceae. Der Gattungsname Commelina wurde 1753 durch Carl von Linné in Sp… Laboratory bioassays using C. benghalensis were carried out to evaluate phytotoxic effects of pure organic acid solutions and dilute extracts of B. plantaginea on seeds germination, root development and fungal germination and AA and FA solutions and the extract of B. plantaginea extract reduced germination and root length of C. benghalensis [73]. Commelina benghalensis has also been identified as an alternate host of the southern root-knot nematode (Meloidogyne incognita) [55]. Particular biotypes are resistant to 2,4-D and they may be cross resistant to other Group O / 4 herbicides [83]. However, he suggested that since dense mats of plant material make chemical weed control of older plants difficult, removal by hand is the only effective control at that stage [84]. Screen for mycobiota with good potential for CBC such as the rust species Uromyces commilinae which has been identified in several Caribbean Islands. [6]. Vegetation regeneration, depth of germination and seed dormancy in Commelina benghalensis L. Rhodesia Journal of Agricultural Research, 17(2):151-154. Origen y distribución 3. © 2013 The Author(s).

Tripa de pollo . Evaluation of herbicides in potato (Solanum tuberosum) in Guatemala. and Radopholus similis in banana [13, 27, 29, 44, 55, 57, 60, 87] and coffee. A new herbicide trial in a cacao plantation at the Station de Nkoemvone. The most effective herbicide control strategies for C. benghalensis involve combinations of both pre-emergence and postemergence conventional herbicides [54]. Some farmers in St. Vincent have also tried this technique in the field with varying success. 22-50. It was stressed that the application of herbicides with soil residual activity will be crucial for the management of C. benghalensis [80]. More information about modern web browsers can be found at http://browsehappy.com/. Commelina communis has become one of the three most troublesome weeds in soybean fields in the Northeast China, and has caused significant reduction in production and quality of soybean [42]. Post-emergent sequential treatments of propanil followed by nitrogen or of molinate followed by KN3 controlled C. diffusa in rice [61]. Rome, Italy: Food and Agriculture Organization. Commelina diffusa was once encouraged as a ground cover to reduce soil erosion [13] and has been identified as the host of the reniformis nematode Rotylenchulus reniformis [57], the banana lesion nematode Pratylenchus goodeyi [87] and recent data have confirmed its association with the burrowing nematode Radopholus similis [55]. There have not been many reports on biological control of Commelina species. Therefore, the optimal application time of imazethapyr was 1-2 leaf stage of C. communis [41]. Waterhouse DF, 1993. Resistance to residual herbicides has also been reported and relatively high doses of simazine and diuron appear to be necessary to achieve control [32]. Native wandering jew (Commelina diffusa) This fact sheet is developed with funding support from the Land Protection Fund. Tagblumen (Commelina) sind eine Gattung in der Familie der Commelinagewächse (Commelinaceae) innerhalb der Einkeimblättrigen Pflanzen. Fomasefen, however, caused damage by burning banana suckers and leaves (about 30%) of established banana plants [30]. By Wendy-Ann Isaac, Zongjun Gao and Mei Li, Submitted: May 23rd 2012Reviewed: January 15th 2013Published: June 12th 2013, Home > Books > Herbicides - Current Research and Case Studies in Use, Herbicides - Current Research and Case Studies in Use, Edited by Andrew J. The world's worst weeds. These mycobiota would appear to be good potential agents for classical biological control (CBC) [14]. F. is a herbaceous tropical plant with different traditional medicinal uses. Desmodium heterocarpon was also found to be competitive to C. diffusa significantly suppressing its growth in Farmer Participatory Research trials also conducted in St. Vincent in 2005/2006 [30]. Commelina diffusa is grazed by small ruminants, pigs and cows. 4. Surely this list can be expanded to include other Commelina species such as C. diffusa which is definitely a problematic weed in the cropping systems in the Windward Islands. Commelina nudiflora auct. [38, 39]. Characterize the environmental limits of C. benghalensis in the U.S.A. [80]. In an interview on August 10, 2002, Paddy Thomas, an experienced banana grower and pesticide salesman in St. Vincent and the Grenadines revealed that farmers started using gramocil (paraquat + diuron) at high doses for example and this too was not effective and resistance in Commelina spp. A weed identification guide for Ethiopia. The document further indicates that the methods currently used include proper land preparation, hand hoeing and pulling, removing the plants from the fields and drying, use of ox-drawn and tractor drawn cultivation, slashing and herbicide application. Manabe T; Ishii K, 1972. Watanabe Y; Hirokawa F, 1975. Mechanical control using the weed whacker may also contribute the spread of stem cuttings in addition to damaging the banana root system as much of the plant lies within the top 15 cm of the soil [30]. Commelina cyanea is a trailing herbaceous perennial plant, whose stems grow along the ground. Nova Odessa, Brazil: H. Lorenzi, 425 pp. Budd GD; Thomas PEL; Allison JCS, 1979. Determine the reasons for reduced seed production of C. diffusa species found under banana fields in the Windward Islands as compared to higher seed numbers (both aerial and underground) of C. benghalensis species in the USA. Pages in category "Commelina diffusa" This category contains only the following page. Many of these studies should be consulted for basic details of the biology and ecology. Commelina nudiflora auct. Impacto e importancia 7. This study aimed to evaluate the hepatoprotective and antioxidant activities of aqueous and methanolic extracts of Commelina diffusa. Aneilema a potyvirus has also been found infecting 15 species of the Commelinaceae family including 4 of Commelina. Arable weeds of Zimbabwe. In Central Virginia, USA, Pycnodees medius (Hemiptera: Miridae) was found to cause tissue necrosis on C. communis [33]. Licensee IntechOpen. Cafe Cacao The, 21(1):41-46. Animals may also spread the seeds. Herbicide trials in rice in Costa Rica. Plantas daninhas de Brasil, terrestres, aquaticas, parasitas, toxicas e medicinais. 1), 22-96. Ciba Geigy, 1982. Inflorescens peduncles 7 – 25 mm long. Soil solarization by covering with plastic sheeting for 6 weeks in the warmer months will weaken the plant. Commelina diffusa is a colonising species of banana orchard habitats in St. Vincent in the Windward Islands of the Caribbean. A new herbicide trial in a cacao plantation at the Station de Nkoemvone. The present investigation was undertaken which deals with the evaluation of central nervous system (CNS) depressant activity of … Extreme tolerance to glyphosate has been documented [54]. (Family: Commelinaceae) is usually known as “climbing dayflower or spreading dayflower” in Bangladesh. In: Resumes de Trabajos, 1a Reunion de Trabajo de la Asociacion de la Associacion Latinoamericana de Especialistas en las Ciencias Aplicadas a las Malezes (ALARM). This can be done by intercropping with melons, Mucuna pruriens (negra and ceniza), tropical alfalfa, Cajanus cajan, Vigna radiata (mung bean), V. unguiculata (cowpea), Crotalaria juncea, Indigofera endecaphylla, Phaseolus trinervius, and Ipomea batatas (sweet potato) which have rapid canopy coverage to suppress the establishment of weeds. The plant produces roots readily at the nodes of the creeping stems and will do so especially when broken or cut [27, 28]. Feeding and nymphal development (up to 3rd and 4th instar) of Cornop aquaticaum (grasshopper) were reported on C. africana L., and Murdannia africana (Vahl.) Weed Science publishes research related to weed science in agricultural systems, such as herbicide resistance, weed control tools, chemistry, and genetics. Stroud A; Parker C, 1989. In cultivated areas the plant is spread by irrigation water and waterways. 21 (1), 41-46. 1. the rusts Phakopsora tecta and Uromyces commelinae) are already present in the New World, they are restricted to certain regions and could be redistributed [14]. (Lista nacional de especies de plantas invasoras y potencialmente invasoras en la República de Cuba - 2011). U2- tobacco mosaic virus has also been found infecting C. communis and Z. pendula. Inflorescens bract (spathe) margin not connate. in the USA [63, 64]. London, UK: Crown Agents. Paviot J, 1977. Distribution and biology. Pesticides should always be used in a lawful manner, consistent with the product's label. Lawrence RM Jr; Habetz R, 1976. Commelina benghalensis is the most important of the three and it occurs as a weed in 25 different crops in 28 countries [27]. Help us write another book on this subject and reach those readers. Burial should be up to 5.0 cm to ensure that there is no emergence of the weed. How? All treatments showed varying levels of control for up to 3 weeks. Noltie HJ, 1994. Research aimed at evaluating the periods of interference of C. benghalensis in the initial growth of coffee seedlings reported prevention periods of 15 to 88 and 22 to 38 days after coffee seedling sowing under winter and summer conditions, respectively [11]. When several references are cited, they may give conflicting information on the status. Pubescence on the stem is variable and ranges from glabrous to hispidulous, which can occur either in a line or throughout. Brome mosaic virus isolates have been identified [70] infecting C. diffusa and C. communis in Fayetteveille, Arkansas, USA. Glufosinate has since been promoted as an environmentally-friendly option for the control of broad-leaved weeds including Commelina species. In: Flora of West Tropical Africa, 3 (1) [ed. Gramoxone Max® and Aim® (acetochlor) can be used post-directed. at a rate of 0.3 – 0.6 kg a.i. Leaves are broadly lance-shaped with closed sheaths. Control using herbicides is, however, variable depending on the herbicide, accuracy of leaf coverage and environmental conditions [7]. CABI, Undated. 1. Fomasefen and lactofen have shown good potential for control of this broadleaf weed [10]. Surfactants will improve penetration into the waxy-coated leaves. Introducción. There are 170 species of Commelina in the warmer regions of the world and 50 species of Murdannia occurring in the tropics and warm temperate regions worldwide with Tropical Asia having the greatest diversity [17]. 68th Annual Progress Report Rice Experiment Station, Crowley, Louisiana, 1976., 82-96. Built by scientists, for scientists. C. diffusa is a smooth and sparsely hairy annual or perennial herb with creeping stems ascending above and branching below. Honolulu, Hawaii, USA: University Press of Hawaii. A multi-component approach including an effective herbicide for successful management has been suggested [80-82]. It is difficult to control in cocoa plantations in Cameroon (Paviot, 1977) though reports from Africa are few. 22-50. To screen more suitable herbicides for control of C. benghalensis and C. communis and determine the level of weed control provided by a single application of selected post-emergence herbicides, greenhouse studies on the laboratory toxicity of 23 herbicides to these weeds were conducted in 2010 [21]. / ha, however, paracol and gardoprim suppressed this perennial weed better [50]. Attempts have also been made to find organic treatments for control of Commelina species in banana in St. Vincent and the Grenadines [30]. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. The weed appears to be well-suited for high input agricultural production where high levels of fertilizers, irrigation and herbicides are used [79, 80]. Holm LG; Pancho JV; Herberger JP; Plucknett DL, 1979. Canberra, Australia: Australian Centre for International Agricultural Research, 141 pp. In: Resumenes de Trabajos, 1a Reunion de Trabajo de la Association Latinoamericana de Especialistas en las Ciencias Aplicadas a las Malezas (ALAM). Cafe Cacao The. ), Second Edition (Ed. Herbicide evaluation in wheat in Guatemala. Alwmman RF; Neito HJ, 1971. Herbicides are not usually very effective against most Commelina species. Our team is growing all the time, so we’re always on the lookout for smart people who want to help us reshape the world of scientific publishing. Commelina diffusa Burm. This fact is evident in young banana plantations in the Windward Islands where stems become dried and shrivelled due to the direct contact with solar radiation particularly in the dry season. Tropical Spiderwort (Commelina benghalensis): A Tropical Invader Threatens Agroecosystems of the Southern United States - Volume 19 Issue 3 - Theodore M. Webster, Michael G. Burton, A. Stanley Culpepper, Alan C. York, Eric P. Prostko In plantation crops such as banana, paraquat is not always effective but mixture with diuron is recommended [7]. Spreading dayflower (Commelina diffusa Burm. Commelina formosa Graham. Tropical Pest Management, 27(3):405-418. Firstly, the fact that the weed was encouraged as a groundcover was compounded by inappropriate agricultural practices, notably irrational herbicide use which farmers have relied on for decades. The best way to control Commelina species for small holders in developing countries would be by implementing an integrated approach that embraces a variety of options which should be attuned to the individual farmer’s agronomic and socio – economic conditions (soil type, climate, costs, local practices and preferences). Common name : Spreading dayflower Common name in Bengali : Manaina, kanainala Common name in Hindi : Kankana Bangla English Hindi Urdu. HeadquartersIntechOpen Limited5 Princes Gate Court,London, SW7 2QJ,UNITED KINGDOM. In field trials in St. Vincent, soil solarization using clear polyethylene plastic at 0.5 mils under Fairtrade banana plants showed variable suppression of C. diffusa as the weed emerged under the clear plastic showing chlorotic and suppressed growth symptoms, resuming its full growth potential after removal of the plastic covering 2 months after application (Isaac et al. There are no reports of work done on the use of these mulches for suppression of Commelina species. Commelina diffusa is the main food plant of L. commelinae, however, it is susceptible to predation by the formicid: Crematogaster brevispinosa as well as competition and exposure to the sun (high temperatures) which causes high mortality [20]. Proceedings 27th Annual Meeting Southern Weed Science Society., 125. and Cleome aculeate L. Banana mulch treatment provided the best control by significantly reducing weed biomass and weed species composition and was followed by Fomesafen, coffee hulls, clear plastic mulch and Desmodium heterocarpon. These cuttings were intended to simulate cuttings made from a weed whacker and the practice of burying the weed. They are both annuals and perennials and therefore dominate the fallow vegetation because they are most competitive due to their growth and regeneration characteristics [72]. However, the performance of those herbicides applied in different crops to control C. benghalensis and C. communis also needs to be ascertained. It is also observed throughout the panhandle and central Florida and listed by the United States Department of Agriculture (USDA) as appearing in more than 12 Florida counties [82]. xlix + 391 pp. began to show. Lorenzi H, 1982. Glyphosate has been shown to be effective but additives or mixtures may be needed for good results at moderate doses [7]. Raabe R, 1965. The stems of Commelina species have a high moisture content and once it is well rooted the plant can survive for long periods without moisture [84]. It readily roots at the nodes when they come into contact with the soil. Pritchard GH, 1971. Weed Research, Japan, No. The results revealed that different fractions of Commelina diffusa Burm. In: Flora of West Tropical Africa. ), pastures, sweet potatoes (Ipomoea batatas), vineyards and barley (Hordeum vulgare) and other cereals in many countries [7]. Similar results using treatments high in nitrogen were obtained in Russia [59] where seed production of C. benghalensis and stunted growth under artificial dense competition in cereals resulted. Studies were conducted into the efficacy of glufosinate for weed control in coffee plantations and it was found that it did not effectively control Commelina spp. The uredinal state of a rust was found widespread on C. diffusa in Hawaii [22] sometimes causing death of parts above ground. Petals usually clear blue, rarely pale blue or purplish. Nova Odessa, Brazil: H. Lorenzi. Wendy-Ann Isaac, Zongjun Gao and Mei Li (June 12th 2013). There are prospects for the management of invasive alien weeds in Latin America using co-evolved fungal pathogens in selected species from the genera Commelina [14]. Description Top of page. unpublished data 2005). New York, Chichester (), Brisbane, Toronto, UK: John Wiley and Sons. Commelina species has gained noxious weed status in the Windward Islands because of several factors. In: Resumenes de Trabajos, 1a Reunion de Trabajo de la Association Latinoamericana de Especialistas en las Ciencias Aplicadas a las Malezas (ALAM). Commelina diffusa is particularly difficult to control by cultivation, partly because broken pieces of the stem readily take root and underground stems with pale, reduced leaves and flowers are often produced [32]. Holm L G, Plucknett D L, Pancho J V, Herberger J P, 1977. Commelina diffusa Burm. by Hutchinson, J. Wallingford, UK: CABI, CABI, Undated a. CABI Compendium: Status as determined by CABI editor. Biología y ecología . Mulching is another viable option for management of the weed. non L. (and C. communis) have occasionally been used as synonyms of Commelina diffusa Burm. One or more of the features that are needed to show you the maps functionality are not available in the web browser that you are using. Brenan JPM, 1968. Its flowers are usually bright blue and have rounded petals. Treatments significantly shifted the species composition away from Commelina diffusa to annual weed species such as Spermacoce latifolia Aubl. Additionally, the adoption within recent years of GM crops particularly herbicide – resistant crops presents serious issues involving their negative ecological impact as already there are reports of Commelina species prominence in some agroecosystems due to simple and significant selection pressure brought to bear by these herbicide – resistant crops and the concomitant use of the herbicide [52]. f., but these names have been used by different authors for more than one taxon and are incorrect when applied to C. diffusa. Regrowth of C. diffusa and other weeds were observed 6 weeks after application with glufosinate, however, no regrowth was observed for up to 3 months with fomasefen. Commelina diffusa is very difficult to control manually as the stolons are cut into small pieces which can easily regenerate. Best results were obtained from Burnout® which caused phytotoxic damage on the leaves of actively growing plants offering 43% control. Treatments significantly shifted the species composition away from Commelina diffusa to annual weed species such as Spermacoce latifolia Aubl. Commelina aquatica J.K.Morton. The virus is transmitted by two insect vectors, Aphis gossypi and Myzus persicae; Aphididae. Volume 3, Part 1 (Ed. Abdul Mannan* and Tajnin Ahmed Abstract Background: Commelina diffusa Burm. Basel, Switzerland: Ciba Geigy Ltd. Daniel JW, 1974. The virus is transmitted by mechanical inoculation and not by grafting or contact between plants or by seeds. Because of Commelina’s vigorous growth habit, which allows the plant to form dense pure stands, they may compete easily with low growing crops such as vegetables, pulses and cereals as well as pasture grasses and legumes by smothering them [27]. It generally grows in moist and/or shady habitats. Results indicate that for effective management of C. diffusa by cutting, nodes must be reduced to less than half with no leaves which may starve the plants’ photosynthetic ability and hence suppress regeneration. spreading dayflower. climbing dayflower. It grows like Blue Commelina on steroids. Identificación y descripción 4. This weed has gained high importance in peanut and cotton in the southern United States [78, 79]. In evaluating the effectiveness of several pre-emergence herbicides in suppressing C. benghalensis emergence, it was reported that s-metolachlor (at 1.07 and 1.60 kg a.i./ha), clomazone (at 0.42 and 1.05 kg a.i./ha) and flumetron (at 1.68 kg a.i./ha) provided ≥ 80% control at 6 weeks after treatment (WAT) in cotton [80]. This species is common in rice in Sri Lanka, sugarcane in India, the Philippines and Mozambique, cassava in Taiwan and maize in Zimbabwe [9]. Results indicate a 94.5% and 95.6% suppression of weeds including C. diffusa with coffee hulls and banana mulch treatments respectively and 100% suppression with black plastic mulch. Sheaths are short with a few soft hairs on the upper margin. Commelina diffusa is susceptible to Commelina X potexvirus, Commelina yellow mottle badnavirus, Spring beauty latent bromovirus, Tradescantia – Zebrina potyvirus, spotted wilt and Cherry leaf roll nepovirus [2]. Use of vigorous healthy planting material and close spacing of the crop may also be used. Hand weeding and rolling the weed up like a carpet is considered suitable for removal of small infestations [30], if care is taken to remove every last piece. Farmers have been forced to rely on the use of the cutlass or weed whacker as the only alternative strategies which have further intensified the problem by spreading plant propagules [30]. Rice Journal, 77(7):31-32, Stamps RH, 1993. There have also been reports of foraging of this weed by Gallus domesticus (chickens) [30]. Interestingly, severe stunting has been reported in C. diffusa caused by high nitrogen [59] and altered growth and physiological characteristics for different C. erecta clones with increased phosphorus supply [71]. The efficacy of imazethapyr (90 g a.i./ha) in controlling C. communis reduced with increased leaf stage, and the control levels at 15 DAT were 100% (at 1 leaf stage), 89.17% (at 2 leaf stage), 56.45% (at 3 leaf stage) and 52.71% (at 4 leaf stage), respectively [41]. Both AA and FA have the potential for use as bio-herbicides. Presently, Commelina species, commonly called watergrass, caner grass, pond grass, spiderwort, spreading dayflower, wandering Jew or French weed in these Islands, are by far the most serious in these countries. Seed germination of C. benghalensis was found to increase by soil solarization in studies conducted in Brazil [43]. To date our community has made over 100 million downloads. The difficulty lies in its ability for regeneration after attempted management even by cultural, mechanical or chemical control. The plant is propagated mainly by seeds, stem cuttings and rooting from nodes and pieces [19, 46, 74, 75]. The plant is used in fever, malaria, insect, bug bites, rheumatoid arthritis, gonorrhea, influenza, and bladder infection etc. Wilson’s review on the control of these weed species was directed towards finding suitable chemicals for their control in the early stages of growth, summarizing results of trials from difference parts of the world [84]. C. diffusa flowering shoot. The initial control of C. diffusa with glyphosate + carfentrazone-ethyl was improved when associated with the adjuvant, mainly for AI11002 and TT11002 nozzles.O trabalho teve como objetivo avaliar a eficiência e a qualidade da tecnologia de aplicação da mistura em tanque de glyphosate + carfentrazone-ethyl no controle de Commelina diffusa. [27]. Pathogens recorded in the native range of Commelina species include: Cercospora benghalensis Chidd., Cylindrosporium kilimandscharium Allesch. Commelina diffusa occurs as a weed in 17 crops in 26 countries and Murdannia nudiflora occurs as a weed in 16 crops in 23 countries [27]. and two fungi (Corynespora cassiicola and Cercospora sp.) It is commonly associated with wet locations. PDF | Weeds are major competitors of rice growing in the farming land. Off print Download the full paper Castillo M; Garcia JG; Rodriquez F, 1971a. Commelina elegans has shown resistance to growth – regulator type herbicides [32]. In fact the species does not pose any threat in competing for nutrients with banana. Prodiamine has been reported to be effective in ornamental fern beds [62]. Original citation: Terry and Micheika, 1987, Original citation: Castillo et al. As reviewed by Wilson (1981), many standard herbicides have relatively low activity on species of Commelina: these include 2,4-D, propanil, butachlor, trifluralin and pendimethalin. Recent data indicates that the Commelinaceae family contains 23 genera and at least 225 species native to or naturalized in the New World and 23 genera and about 200 species in the Neotropics [41] and also website reports of 50 genera and 700 species [16, 31]. Primera página de la especie Inicio del sitio (Home) 1. Plants may arise asexually when buds grow into autonomous, adventitiously erect leafy shoots, which later become separated from each other [12]. Secondly, the move within recent years by banana growers to adopt a Fairtrade system which uses no herbicides has catapulted the spread to an all-time high in the Windward Islands. Smith RJ Jr, 1974. Baker J B, 1977. Moroco Weed 3., Basel, Switzerland: Ciba Geigy Ltd. Drummond RB, 1984.
