Only 2 per cent of horticulture produce is processed, 0.4 per cent is exported and about 20-30 per cent is lost or gets wasted in market chain. forest, coastal forest and mangrove forests. However, its potential distribution is much wider than at present. vol. In Kano State, the S. hermonthica population was negatively related to latitude, total N, and exchangeable K and was positively related to sand and silt in maize fields. The Striga gesnerioides population in Bauchi State was higher than that recorded in Kano State. Implications of this finding are discussed in the light of the species’ invasion and biocontrol in South Asia, Southeast Asia and the Philippines. In both states > 90% of cowpea fields had coarse textured soil. Species of mangroves (Rhizophora apiculata) dominates Chromolaena odorata: Siam weed. Soil pH ranged from 5.0 to 7.4 in maize fields, 5.5 to 6.7 in sorghum fields, and 5.4 to 8.3 in cowpea fields in Kano State. The ecology of the highly invasive plant species C. odorata is poorly studied in the Philippines in spite of the fact that it is hard to eradicate, a nuisance in plantations, and known to harm farm animals and decimate forage and native plant species. Sterilization of these soils eliminated their inhibitory effect. The country has recorded highest productivity (25.4 tonnes/ha) in the case of grapes in the world. The medusae were closely similar to C. mosaicus and C. townsendi in many aspects except that the surface of the central portion of their exumbrella was smooth, and not coarsely granulated. Proc. In Bauchi State, an average of two to three maize plants/m2 was attacked by S. hermonthica in all the communities. Drawing on these findings and the detailed narratives of farmers, the article submits that the challenge for the natural recruitment of trees in the study region is for farmers to adopt land management practices that significantly increase the numbers of tree species while reducing the competition from non-tree species, such as C. odorata. Siamweed. 105-112. Cecidochares connexa was not found at any of the nine localities surveyed around Luzon. Species composition differed between remnant forests and exotic tree species-based reforested areas for tree species and epiphyte species, while composition differences between the Luzon and Mindanao biogeographic sub-regions were limited to tree species only. which inhibit native plants,” Journal of Ecology, vol. Mean soil pH in, ODES FOR EACH SPECIES ARE USED IN THE MULTIVARIATE CANONICAL CORRESPONDENCE ANALYSIS, AND SOIL TYPE AT THREE SAMPLING SITES IN THE, > 0.25) were generated by CCA. It is concluded that both these species should be declared noxious weeds throughout the Republic and that research into their biological control is urgently required. Data on Striga population, number of crops attacked by Striga, and host reaction were subjected to analysis of variance. Alien clearance is an essential and invaluable management tool. The reasons for lack of returns in agriculture are traditional way of marketing through middlemen, fragmented supply chain and. In the lowland tropical CanoDraw for windows user guide. Others argued that the species may be considered as a beneficial fallow plant rather than a weed, because it may be considered as a welcome plant rather than a weed in some agricultural systems, when considering the expected properties of species for fallow improvement. San Beda College Manila Philippines lilyacero1@yahoo.com Abstract—Chromolaena odoratahas been known as nuisance weed in agricultural farms. Irrespective of type of cropped field, soil reaction in the communities was strongly acid (5.0–5.5), moderately acid (5.6–6.0), slightly acid (6.1–6.5), neutral (6.6–7.5), or alkaline (7.4–8.0). The potential threat posed by each species is estimated and the species are ranked in order of priority for control action. Chro-molaena root leachate experimentally added to uninvaded soils increased Fusarium spore density by over an order of magnitude, and increased the inhibitory effect of the soils. 5. 2. Synthesis. La albahaquilla de Cuba [1] (Chromolaena odorata) es un arbusto de la familia del girasol nativo de Norteamérica, desde Florida y Tejas a México y de la Indias Occidentales. An important limiting factor on labour-intensive small-scale agricultural production in Ghana is competition from weeds for environmental resources, such as soil nutrients, moisture and sunlight. In Bauchi State, the range was from 5.6 to 7.5 in maize fields, 5.5 to 7.9 in sorghum fields, and 5.5 to 7.5 in cowpea fields. The South American composite, Chromolaena (Eupatorium) odorata, is identified as being the alien species currently posing the greatest threat to natural vegetation in the Complex. 1. Average number of sorghum plants/m2 attacked by Striga ranged from 0.98 to 5.4 plants/m2 in Kano State and from 1.22 to 4.23 sorghum plants/m2 in Bauchi State. at the same institution from 1998 to the present. List of various diseases cured by Chromolaena Odorata. 1, pp. Consequently, it is fundamental to document the impact that alien invasive plants have on native communities and to determine if, and at what rate, native communities re-establish following the removal of invasives. The Asian tree, Melia azedarach, is considered the second most important alien species invading the area. Indeed, the introduction of non-indigenous species into protected areas is a direct threat to conservation. Our data show that the removal of alien invasive plants benefits biodiversity with immediate effects, highlighting that management should be carried out to control this invasive, even if the area has been invaded for a long period of time. 2003;Sa´nchez-Blanco et al. The Striga population in all crop fields differed significantly among communities in both states. Usually, chromolaena odorata can be found on the height from 1000 to 2800 above the sea level. Maximum Entropy (Maxent) was applied to assess their habitat suitability, risk area identification and shifts in range sizes. The positive effect of Chromolaena root leachates on Fusarium spores was attenuated by activated carbon, suggesting a biochemical basis for how the invader stimulated the pathogen. 2. International Journal of Environmental Science and Development, Mindanao State University - Iligan Institute of Technology, Preliminary Study on the Distribution of the Introduced Gall-forming Fly, Cecidochares connexa (Macquart) (Diptera: Tephritidae) for the Biological Control of the Invasive Alien Weed Chromolaena odorata (L.) R.M. Ethanol and aqueous crude extracts of C. odorata leaves were tested on seed germination and seedling growth of Lycopersicum esculentum (tomato). These findings support the use of these extracts as potential sources of natural antioxidants. 40, no. King & H. Rob. Note: Kindly Login or Register to gain access to this article. The study covered 300 homesteads from five unions. Chromolaena odoratais a perennial shrub native to tropical America. Grasslands not burnt for 20 years succeed naturally to secondary forest or savanna, depending on soil type and aspect. Coconut, country bean, The purpose of the study was to determine the plant biodiversity and distribution of fruit, timber and vegetable species in the Haor homestead of Bangladesh and to explore the relationship between plant grower’s characteristics and plant biodiversity. path method. Among them 30.9% fruits, 29.09% timber, 34.54% vegetables and 5.45% were spices species. Chromolaena odorata has long been referred to as Eupatorium odoratum. The gall fly, Procecidochares … Herbaceous aliens were not surveyed. However, the revised model supports the previous conclusions that much of tropical Africa, the north-eastern coast of Australia and most Pacific islands are at risk of invasion. Predictions made for the current condition was subsequently projected for the years 2050 and 2100 for both moderate and extreme climate change scenarios. Conservation attention should focus on protecting remaining forests and planting native species as part of a forest restoration strategy to enhance faster forest recovery and re-connecting remnant forest patches. Chromolaena odorata, or Christmas bush and Siam weed, has been spotted inclusively in the presence of resurrection fern on the top of the roof. Agricultural marketing occupies an important place particularly in the context of the new liberalization process and value addition requirements of the agriculture sector. Some authors considered C. odorata as a serious weed because of its ability: to regenerate and colonize uninvaded areas; to be a threat to some ecosystems and environment; to reduce the biodiversity of grasslands, savannahs and forests; and to be a considerable problem in commercial tree plantations as it suppresses the growth of young pine and eucalypt trees. Findings showed that wellawel (Chromolaena odorata) leaf extract contains alkaloids, cardiac glycosides, luecoanthocyanins, flavonoids and tannins. 1, pp. 96, no. Biocontrol of Chromolaena odorata in Papua New Guinea Michael Dayl and Ingu Bofeng2 1 Alan Fletcher Research Station PO Box 36, Sherwood, Qld 4075, Australia, E-mail: ... Cecidochares connexa from the Philippines in 2001 and the leaf mining fly Calycomyza eupatorivora from South Africa in … It was recognized as the most problematic weed in coconut plantations in Sri Lanka as early as 1944, and became a problem in rubber, palm oil, tea, coffee, cashew, teak and other plantation crops in Asia [4]. Also, the agricultural marketing sector is characterized by fragmented supply chain. L. S. Koutika, and H. Rainey, “Chromolaena odorata in different. Twenty seven fruits, 23 timbers, 17 summer vegetables and 12 winter vegetables species were identified. These results show that C. connexa has firmly established in the country and that it has the ability to disperse long distances to new areas. 446-458, factors on seed germination and emergence of Chromolaena odorata in, coconut plantations in Sri Lanka. Fire- induced mortality of the weed depends on grass fuel loads. This article combines primary social research based on surveys and in-depth interviews, and ecological research based on experiment and secondary research to explore the efficacy of three land use management practices, compared with their alternatives, in dealing with on-farm weed problems in Gyamfiase-Adenya-Obom, Ghana. Small lingering differences are observed between the native and the cleared sites, suggesting that other features of the habitat may have been affected by the invasion and clearing. 3&4, pp. Column chromatographic elution of ethanol crude extract yielded 11 fractions, each of which was subjected to bioassay. Conservation Status of the Plant Species in Selected Areas with Frequent Human Activities in Roosevelt Protected Landscape, Bataan, Luzon Island, Philippines, Comparative Study of Phenolic Content and Antioxidant Activity of Leaf Extracts of Alstonia boonei and Eupatorium odoratum, Global Journal of Environmental Science and Management Ecological niche modeling of invasive alien plant species in a protected landscape NUMBER OF REFERENCES 34 NUMBER OF FIGURES 3 NUMBER OG TABLES 4, Assessing harmony in distribution patterns of plant invasions: a case study of two invasive alien species in India, Level and extent of Striga infestation of maize and cowpea crops in Bauchi and Kano states, Nigeria, Vegetation Analysis Of Coastal Forests, Lowland Tropical Forests And Mangroves Ecosystem In Sempu Island Nature Reserve, Alien trees, shrubs and creepers invading indigenous vegetation in the Hluhluwe-Umfolozi Game Reserve Complex in Natal, Managing Chromolaena odorata in subtropical grasslands in KwaZulu-Natal, South Africa, The potential distribution of Chromolaena odorata (Siam weed) in relation to climate.

In Kano State, 194 (maize: 33; sorghum: 161) fields were sampled and 168 (maize: 100; sorghum: 68) fields in Bauchi State. 5. 1189-1197, August 2008. This article examines the potential for the natural recruitment of trees from the soil seed bank following various types of agricultural land uses and conditions associated with them in the Suhum–Kraboa–Coaltar district of the Eastern Region. In the coastal forest ecosystems has been found 20 species of plants and three Included for each species are descriptive information, ecology, distribution, poisonous principle(s), toxic part(s) of the plant, animal(s)liable to be poisoned, and symptoms as observed in the field. The study indicated that while more frequent weeding was generally more effective in suppressing weed densities than less frequent weeding, the effect of weeding in significantly reducing weed densities was not associated with weeding frequency per se but with how carefully weeding was accomplished. Cleome serrulata: Rocky Mountain bee plant. [1] [2] Son nativos de las Américas, desde el sur de Estados Unidos a América del Sur (sobre todo Brasil).Una especie, Chromolaena odorata, se ha introducido en muchas partes del mundo donde se considera una mala hierba. 13–27, January 2001. flora, in a rain forest zone, south-west Cote d’Ivoire,” Journal of. Dysphania spp. 2. 2012) that has also been found in many parts of Philippines and the Asian region affecting biodiversity and favoring disturbed habitats (Muniappan et al. Organic C in Kano State and available P in Bauchi State where negatively related to sorghum grain yield. Subsequently, it was documented on Busuanga Island, Palawan; at Davao City; and San Jose, Mindoro Occidental (Pancho & Plucknett 1971, Aterrado & Bachiller 2002, Lariosa et al. The Philippines is both a megadiversity country and a global biodiversity hotspot. KEYWORDS: phytochemical, antifungal, Chromolaena odorata, Siam weed, ethanolic extracts, bioactive agents. 4, pp. of the Second International, Workshop on Biological Control and Management of Chromolaena. Microcomputer Power, 2002. growth and reproduction in Chromolaena odorata,” in Proc. Seedlings are killed during annual veld-burning in sparse and moderate infestations. This plant can be weedy or invasive according to the authoritative sources noted below.This plant may be known by one or more common names in different places, and some are listed above. Huge postharvest losses, multiple market intermediaries; higher transaction cost, lack of awareness and several other socio-economic factors are some of the acute problems being faced by the Indian agriculture. The gross morphology of one of the world’s worst invasive plant species, Chromolaena odorata, now widespread in three provinces of the Zamboanga Peninsula, was examined and compared to the characteristics of Asian/West African (AWA), Southern African (SA), and … Samples were taken at three ecosystems that exist in this conservation area is a lowland tropical 131-142, 2010. 44, no.

Natal,” Bothalia, vol. A sign in Kloof encouraging the elimination of Chromolaena odorata, colloquially known as Triffids Chromolaena odorata is considered an invasive weed of field crops and natural environments in its introduced range. in the group of trees. Chromolaena odorata (L.) King and Robinson (Siam weed) extract has been used to stop bleeding and in wound healing in many tropical countries. The results emphasize the importance of understanding forest recovery in disturbed ecosystems. Modelling, vol. None of the plant species was found in the 100% haor homestead. The high abundance in our sampling sites was not, unexpected because sites had ideal exposure to sunlight, which is needed for germination, seedling growt, may need to be planted with shade-adapted high value crops, (e.g. The 0.5% ethanol crude extract also reduced the mitotic index in Allium cepa (onion) root tips. The following are the main reasons why C. odorata is considered as a fallow because of it ability: to be a nutrient sink and its potential benefit to the crop as regular source of organic matter and nutrients after slashing; to have a beneficial effect on exchangeable K concentration; to be used as green manure; to be better adapted as a fallow plant on acidic soils than some leguminous. The results revealed that the DPPH radical scavenging ability of aqueous extract of E. odoratum (with IC50 = 0.07± 0.003mg/ml) compares favourably with that of the standard ascorbic acid (IC50 = 0.06 ± 0.01 mg/ml). (Authors' abstract) SUBJECTS Biology Chromolaena odorata Biotype The ethanol extract of E. odoratum had the highest FRAP while the aqueous extract of A. boonei showed the highest RP ability when compared with the other extracts. Dactyloctenium radulans: button grass, but only when growing in high-nitrogen soil, such as in stockyards. No significant, relationship between soil parameters and vegetation, tends to be of maximal abundance in the presence of, Zamboanga Peninsula seems to be favored by an acidic soil, and the range of soil parameters measured in this study. Chromolaena odorata, along a 15 year chronosequence,” Plant Ecology.

Access scientific knowledge from anywhere. The distribution of C. odorata could mostly depend on temperature and moisture availability; and invade the biodiversity-rich regions of India viz., the Eastern Ghats, the Western Ghats, the Eastern Himalaya and the north-eastern regions. Phytochemical screening of fractions 4 and 5 are positive for the presence of alkaloids and steroids that may have caused the inhibition of seed germination and seedling growth in L. esculentum, and the reduction of the mitotic index in A. cepa root tips. Está incluido en la lista 100 de las especies exóticas invasoras más dañinas del mundo de la Unión Internacional para la Conservación de la Naturaleza. 3. Mulching slashed vegetation, as a land preparation practice, was also consistently better at reducing weed densities than burning the slashed vegetation. species nails and orchids. a common characteristic for many weed species [10]. cacao and coffee) to preclude invasion of, Abundance and successful invasion is most likely, influenced by the biology of the species (e.g., the allelopathic, rather than by local edaphic conditions. 100, no. Indian agriculture has registered impressive growth over last few decades. The distribution, nature and history of the infestations of each species are summarized. Total phenol, flavonoid and flavonol content of the extracts were estimated to determine the levels of phenolics in the extracts. 45, no. Chromolaena odorata is one of the most important invader species in the savanna biome in South Africa. 5. 2009;Li et al. The relative prevalence of most common fruit plant like betel nut, banana, mango were 115.074, 63.558, 74.358 respectively while the lowest reletive prevalence was observed for very rare timber species like Babla, Champa and Jarul. It has been utilized in the traditional medicinal systems for its … Invasions by alien plants into unspoiled ecosystems are a cause for concern because the pristine systems are important stores of biodiversity.
