4. Zachariades C, Strathie LW, Day MD, Muniappan R (eds) ARC-PPRI, Pretoria (2013) pp 117-126 117 Biocontrol of Chromolaena odorata in Papua New Guinea 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. 4. 5. Wellawel leaf extract has weak antimicrobial activity against Bacillus subtilis, Escherichia coli and no anti-fungal activity on Candida albicans. 8, no. Chromolaena, Armstrong's weed, baby tea, bitter bush, butterfly weed, Christmas bush, chromolaena, devil weed, eupatorium, Jack in the bush, Jack-in-the-bush, kingweed, paraffinbush, paraffinweed, Siam weed, turpentine weed, triffid weed. Siamweed. In both states > 90% of cowpea fields had coarse textured soil. It has been utilized in the traditional medicinal systems for its … Exclusively distributed by CE-Logic | Terms and Conditions, IAMURE International Journal of Terrestial Ecology. ... Indonesia, Philippines, Western Caroline Islands, Mariana Islands and India. Grasslands not burnt for 20 years succeed naturally to secondary forest or savanna, depending on soil type and aspect. Organic C and exchangeable K in Kano State and available Cu in Bauchi State were positively related to maize grain yields. (Copasanda) which an invasive species. Here we assessed harmony in plant invasions of two perennial exotic species of similar origin and naturalised in India, i.e., Chromolaena odorata and Tridax procumbens. Chromolaena odorata is a fast-growing perennial shrub, native to South America and Central America. The crop physiological responses to environmental. In Indonesia, chromolaena odorata as opposite, can be found in lowland about 500 above the sea. But, it is a different case in Indonesia. Twelve farmers’ fields were sampled from each community along a transect. We are also g. to the copyediting assistance of Dr. MTRD Sanchez-Metillo. It is likely that C. connexa will continue to disperse further with time. In Bauchi State, these two parameters ranged from low (Ca: < 2; Mg: < 0.3 cmol/kg) to high. Under conditions where head-fires cannot be used for killing dense stands, infestations must be slashed and burnt at the height of the dry season. Chromolaena density affects grassland species composition, with dense stands in grassland being monospecific. Correlation and stepwise multiple regression was used to relate Striga population and crop yields to measured soil parameters. Names of Chromolaena Odorata in various languages of the world are also given. 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. 2005; ... Introducido en regiones tropicales de Asia y África, donde se ha convertido en invasora. The potential threat posed by each species is estimated and the species are ranked in order of priority for control action. Only 17 fruit, 13 timber, 17 vegetable and 2 spices species were found in all region. The prevalence of T. procumbens in central regions of India could demonstrate its greater dependencies on precipitation seasonality and radiation than that on temperature. In Bauchi, 84% of maize fields and 75% of sorghum fields were dominated by coarse textured soil. 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. Chromolaena odorata, along a 15 year chronosequence,” Plant Ecology. However, farmers’ perception of Striga as the major cause of poor crop growth and low yield agreed with the result of the study. 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. Environmental Research, vol. The distribution, nature and history of the infestations of each species are summarized. Sixty-four cowpea fields in Kano State were sampled and 49 in and Bauchi State. Interestingly, there were significantly fewer numbers of exotic species in bigger remnant forest sites and in older exotic tree species-based reforested sites, while larger numbers of native species occurred in older than in younger exotic tree species-based reforested sites. 2. The Striga gesnerioides population was negatively related to cowpea grain yield. Cleome serrulata: Rocky Mountain bee plant. More recent surveys have identified infestations in the Townsville-Thuringowa, Mossman and Mt Garnet areas. We found that rhizosphere soils of Chromolaena odorata, one of the world's most destructive tropical invasive weeds, accumulate high concentrations of the generalist soil borne fungi, Fusarium (tentatively identified as F. semitectum), thus creating a negative feedback for native plant species. Non-native plants that can cause adverse effects are otherwise known as invasive alien plant species which pose a major threat to plant biodiversity conservation and sustainability. Ajmiriganj upazila of Hobigonj district of Bangladesh was the study area. 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. Many efforts are being made for the control of this weed. 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. Depending on chromolaena density, soil type and aspect, grasslands can be rehabilitated and managed in multiple states, namely as grassland, savanna or forest communities. 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. In the lowland tropical forest ecosystems, species found Myristica Soils collected beneath Chromolaena in the Western Ghats of India inhibited naturalized/native species and contained over 25 times more spores of the pathogenic fungi Fusarium semitectum than soils collected at the same locations beneath neighbouring native species that were at least 20 m from any Chromolaena plant. The distribution of the gall fly, a biological control agent of chromolaena or Siam weed, was determined for the three main islands – Luzon, Visayas, and Mindanao –18 years after its … The suppression of seedlings in dense infestations requires chemical control until grass cover is sufficient to effect uniform burning. 246-254, August 2005. Available P which ranged from 0.69 to 40.8 mg/kg in Kano State and 1.79 to 59.0 mg/kg in Bauchi State fell within the major fertility classes of low (< 10 mg/kg), medium (10–20 mg/kg), and high (> 20 mg/kg). In the Philippines Siam weed is a highly invasive plant species which is poorly studied 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. Restauración de la cobertura vegetal en áreas previamente afectadas por la minería aluvial de oro en el Nordeste de Antioquia, Colombia. 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. 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. habitats and was conspicuously absent in dense shady forests, [20]. The existing marketing system needs to be updated through improvement in skills, knowledge, attitude etc. 220, no. 137-139. These discrepancies in climatic dependencies allowed both for a harmonious distribution, i.e., inhabiting in regions not utilised by other. Results from the association of the physicochemical factors and the presence of invasive alien plant species through Spearman rho test revealed that most of the physicochemical factors have significant association except percent slope and hill shade. In the coastal forest ecosystems found a herbaceous plant that is Chromolaena odorata 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. Twenty alien tree, shrub and creeper species currently invading indigenous vegetation within the Complex are listed. The highest species diversity was found in Mango (0.992), Coconut (0.990), Papaya (0.987) and that of lowest was found in fig, Ipil-ipil and Champa respectively. 1. contributes 28 per cent of agricultural GDP. Of these, 21 species were categorized as threatened species. 4, pp. C. odorata from the three provinces of Zamboanga Peninsula is very similar with the AWA and the Central and South American biotypes. San Beda College Manila Philippines lilyacero1@yahoo.com Abstract—Chromolaena odoratahas been known as nuisance weed in agricultural farms. Proc. 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. We investigated the role of a native generalist soil pathogen through which a non-native invasive plant species may suppress naturalized/native plant species. Biological control of Chromolaena odorata: Preliminary studies on the use of the gall forming fly, Cecidochares connexa in the Philippines, Exotic invasive plant accumulates native soil pathogens which inhibit native plants, Rehabilitation of forest-savannas in Ghana: The impacts of land use, shade, and invasive species on tree recruitment, Spider responses to alien plant invasion: The effect of short- and long-term Chromolaena odorata invasion and management, Dealing with weedy problems in agriculture: The role of three agricultural land use management practices in the forest-savanna ecological zone of Ghana. Chromolaena odorata also invades most areas in the humid paleotropics and subtropics (India, South East Asia, Indonesia, Philippines, Papua New Guinea, parts of Oceania), and is predicted to spread further (McFadyen and Skarratt, Usually, chromolaena odorata can be found on the height from 1000 to 2800 above the sea level. Data from 90 10x10 m randomly established plots using the quadrat method showed that there are 318 plant species wherein 208 are native, 100 are non-native, and 10 are invasive. 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. Chromolaena odorata on Timorese livelihoods,” Human Ecology, odorata in subtropical grasslands in KwaZulu-Natal, South Africa,” in, Management of Chromolaena odorata, Durban, South Afri, Janssen, “Growth of the Chromolaena odorata fallow vegetation in, semi-permanent food crop production systems in South-West Côte. Natal,” Bothalia, vol. It was first recorded in the Philippines on the Zamboanga Peninsula in the 1960s through traders from Borneo (Codilla & Metillo 2011). 3. 1&2, pp. How Chromolaena Odorata is effective for various diseases is listed in repertory format. [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. bioactiv, compounds [24], fallow plant for acidic soils [25]) of the, We deeply thank the Philippine Commission on Higher. zoology in Mindanao State University Marawi City, Philippines in 1994, and Master of Science, Education in Mindanao State University-Iligan. Education for the scholarship grant to LT Codilla, JL Codilla for the help in field sampling. potassium was lowest in Zamboanga del Norte. Its invasiveness is partly associated with allelopathic properties, but phytotoxic and antimitotic potentials of C. odorata from the Philippines have not been studied. Predictions made for the current condition was subsequently projected for the years 2050 and 2100 for both moderate and extreme climate change scenarios. The herb/shrub species, Chromolaena odorata is identified as a primary factor for the difficulties of tree recruitment. Galls start to appear within 12-15 days after oviposition. Soils collected beneath Chromolaena in the Western Ghats of India inhibited naturalized/native species and contained over 25 times more spores of the pathogenic fungi Fusarium semitectum than soils collected at the same locations beneath neighbouring native species that were at least 20 m from any Chromolaena plant. The Chinese banyan (Ficus retusa) dominate this ecosystem. species nails and orchids. This study is dedicated to determine the plant diversity and to assess the vulnerability of Quezon Protected Landscape, Southern Luzon, the Philippines to invasive alien plant species.
