teysmannii recorded endemic status and the status of the plant is labeled critical for the existence of this plant, Sparse to moderate infestations with more than 30% grass cover are killed by fire. at the same institution from 1998 to the present. 1, pp. potassium was lowest in Zamboanga del Norte. 2012;Padmanaba and Corlett 2014). 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. C. odorata from the three provinces of Zamboanga Peninsula is very similar with the AWA and the Central and South American biotypes. (Authors' abstract) SUBJECTS Biology Chromolaena odorata Biotype 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. Species of mangroves (Rhizophora apiculata) dominates There are a substantial number of programmes that aim to control alien invasive plants but very little is known about the way in which biodiversity recovers after alien plant removal. Findings showed that wellawel (Chromolaena odorata) leaf extract contains alkaloids, cardiac glycosides, luecoanthocyanins, flavonoids and tannins. Windows appear on the gall one month after oviposition and attain a maximum width of 9.7 mm and length of 13.7 mm. Inter species diversity was highest (0.879) in the vegetable species. contributes 28 per cent of agricultural GDP. Both are likely to reduce their potential distribution areas in the future climate, where moisture availability is a key factor for their range expansion. 2003;Sa´nchez-Blanco et al. Chromolaena odorata (L.) King and Robinson, an invasive species of the Asteraceae Family, is a weedy shrub native to the warm Central and South America but has successfully invaded other regions of the world including the Philippine islands. The nomenclature of Chromolaena odorata (L.) R.M. Chromolaena odorata in Ghana,” in Proc. Column chromatographic elution of ethanol crude extract yielded 11 fractions, each of which was subjected to bioassay. 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. 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 … The country has recorded highest productivity (25.4 tonnes/ha) in the case of grapes in the world. 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. The Striga gesnerioides population in Bauchi State was higher than that recorded in Kano State. 4, pp. Available Fe in Kano State (68–155 mg/kg) and Bauchi (38–219 mg/kg) was within the range (140–280 mg/kg) reported in a similar agroecology in northern Nigeria. Forest succession in grassland also ceases once chromolaena becomes thicket-forming. In both states > 90% of cowpea fields had coarse textured soil. and spices (3 spp.). factors such as water availability and temperature are highlighted. 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. This study, therefore, reveals that aqueous extract of A. boonei and ethanol extract of E. odoratum leaf are more effective free radical scavengers and antioxidants relative to the other extract forms. Climate change enhances invasive species distribution by altering species composition in native ecosystems. different species of vegetation. It is also very widely naturali… 31, no. The distribution, nature and history of the infestations of each species are summarized. Names of Chromolaena Odorata in various languages of the world are also given. 8, no. Number of vegetable species was found the highest (19 spp.) 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. Chromolaena 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. 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. However, its detailed mechanisms have not been elucidated. Dactyloctenium radulans: button grass, but only when growing in high-nitrogen soil, such as in stockyards. In Kano State, an average of three maize plants/m2 was attacked by S. hermonthica in Danmako, Bebeji LGA and Burji, Doguwa LGA. Coconut was found 98.63% in homestead followed by mango (96.72%), banana (91.6%) and betel nut (93.44%). Trees in Chromolaena odorata (L.) King and Robinson, an invasive species of the Asteraceae Family, is a weedy shrub native to the warm Central and South America but has successfully invaded other regions of the world including the Philippine islands. Education for the scholarship grant to LT Codilla, JL Codilla for the help in field sampling. The present study reveals harmony in their distributions and suggests distinct conservation protocols for each of them to control their invasion risks. 13–27, January 2001. flora, in a rain forest zone, south-west Cote d’Ivoire,” Journal of. Many efforts are being made for the control of this weed. For most of these crops, photosynthesis is treated as a central process affecting growth and crop performance. Its negative impacts on agriculture and biodiversity are clear. 6, pp. 2005; ... Introducido en regiones tropicales de Asia y África, donde se ha convertido en invasora. Chromolaena odoratais a perennial shrub native to tropical America. 1, pp. Some impacts of, M. J. Goodall, and P. J. K. Zachariades, “Managing Chrom. The existing marketing system needs to be updated through improvement in skills, knowledge, attitude etc. Also, the agricultural marketing sector is characterized by fragmented supply chain. This report provides a synthesis of the result of a biophysical baseline survey on the level and extent of Striga infestation of maize, sorghum, and cowpea in the IITA project areas in Kano and Bauchi states. a common characteristic for many weed species [10]. 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, (Asteraceae) in the Philippines, Fresh Siam (Chromolaena odorata) Weed Leaf Extract in the Control of Housefly (Musca domestica), Plant diversity patterns in remnant forests and exotic tree species-based reforestation in active limestones quarries in the Luzon and Mindanao biogeographic sub-regions in the Philippines. 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). A taxonomic paper describing this species is under preparation. 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. Nonetheless, such level of abundance already, M. P. Mgobozi, M. J. Somers, and A. S. Dippenaar-Schoem, R. C. McFadyen, “Chromolaena in East Timor: history, extent and, D. M. Richardson, and B.

KEYWORDS: phytochemical, antifungal, Chromolaena odorata, Siam weed, ethanolic extracts, bioactive agents. bioactiv, compounds [24], fallow plant for acidic soils [25]) of the, We deeply thank the Philippine Commission on Higher. 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. Chromolaena biocontrol has limited potential in grassland and savanna ecosystems except in dense infestations to facilitate grass establishment. It is also used as a reforestation species in RPL. species on tree recruitment,” Applied Geography, vol. Samples were taken at three ecosystems that exist in this conservation area is a lowland tropical 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. In Bauchi State, these two parameters ranged from low (Ca: < 2; Mg: < 0.3 cmol/kg) to high. of the Second International, Workshop on Biological Control and Management of Chromolaena. These data are important for policy-forming and informing policy-makers that alien invasion and removal are critical for biodiversity conservation management. The results emphasize the importance of understanding forest recovery in disturbed ecosystems. 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 (L.) King and Robinson (Siam weed) extract has been used to stop bleeding and in wound healing in many tropical countries. The potential threat posed by each species is estimated and the species are ranked in order of priority for control action. 100, no. The prevalence of T. procumbens in central regions of India could demonstrate its greater dependencies on precipitation seasonality and radiation than that on temperature. Insights into the opportunities and the challenges of recruiting trees for the rehabilitation of these forests are much needed. It has been utilized in the traditional medicinal systems for its … Chromolaena odoratawas found in open well-drained ground like dry and exposed slopes, roadway gullies, and in abandoned fields and pastures throughout the Zamboanga Peninsula. ... Eupatorium odoratum, also known as Chromolaena odorata (L.), is a wildly growing free standing shrub from the family of Asteraceae. Several gaps in our database concerning ecophysiology of tropical tree crops are indicated, major advances are examined, and needs of further researches are delineated. 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. In Kano State, 194 (maize: 33; sorghum: 161) fields were sampled and 168 (maize: 100; sorghum: 68) fields in Bauchi State. Exchangeable K which ranged from 0.14 to 0.66 cmol/kg in Kano State and 0.13 to 0.88 cmol/kg in Bauchi State was low (0.2–0.30 cmol/kg) to medium (0.3–0.6 cmol/kg) in most communities. Chromolaena odorata has long been referred to as Eupatorium odoratum. Currently horticulture. But, it is a different case in Indonesia. mination revealed that the Catostylus medusae in Southern Philippines (Panguil Bay) do not match with the descriptions of any reported valid species of Catostylus. This study investigated the in vitro antioxidant activity and phenolic content of aqueous and ethanol extracts of Alstonia boonei and Eupatorium odoratum leaves. The aim of the survey was to determine Striga incidence and infestation and relate these to soil fertility status and crop yields (maize, sorghum, and cowpea) and to ascertain farmer’s perception on soil fertility and Striga problems in the project areas. 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 deci mate forage and native plant L. S. Koutika, and H. Rainey, “Chromolaena odorata in different. Robins. Zamboanga del Sur, Philippines on January 24, 1973. Chromolaena odorata is one of the most important invader species in the savanna biome in South Africa. Among them 30.9% fruits, 29.09% timber, 34.54% vegetables and 5.45% were spices species. Soil pH, aspect and number of non-native plants show positive association while soil moisture, leaf litter thickness, elevation, species richness, species evenness, plot species diversity index, and the number of native plants signify negative association. These discrepancies in climatic dependencies allowed both for a harmonious distribution, i.e., inhabiting in regions not utilised by other. 8-10. However, a more robust study regarding its presence in other parts of the country and its effectiveness as a biological control agent is needed. codes). 4. 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 … 1&2, pp. More than 90% of the closed canopy forests and their immense biodiversity in the forest-savanna ecological region of Ghana have been cleared since the late 19th century. The fallow management practice of >3 years of fallow showed significantly greater promise of suppressing weeds than ≤3 years of fallow. 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. 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. 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. highest Important Value Index (IVI) in the tree category. Biological control has a major role in rehabilitating grassland to secondary forest or in forest ecosystems that have become invaded. Uses, Benefits, Cures, Side Effects, Nutrients in Chromolaena Odorata. She is now a Ph.D. biology, Philippines, Inc. and a member of the Philippines Society for, Matunggao, Province of Lanao del Norte in the island, of Mindanao, Republic of the Philippines on 20 April, 1968. In both states, the Striga population was negatively correlated with maize, sorghum, and cowpea grain yields. Flores en racimos blancos con potencial apícola. 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. 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. 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. Exclusively distributed by CE-Logic | Terms and Conditions, IAMURE International Journal of Terrestial Ecology. 4, pp. However, in Bauchi State available Fe, Cu, clay, organic C, and total N were negatively related to S. gesnerioides and explained 60% of the variation in its population. Training Need Assessment of Officers Working in Agricultural Marketing in India, Plant Biodiversity in the Homesteads of Saline Area of Southeastern Bangladesh, Plant-Biodiversity at Ajmerigang Haor Homesteads of Bangladesh, Ecophysiology of tropical tree crops: An introduction. King and H. Robinson, commonly known as Eupatorium odoratum L. was updated. 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. Wellawel leaf extract has weak antimicrobial activity against Bacillus subtilis, Escherichia coli and no anti-fungal activity on Candida albicans. Plant biodiversity was described by Species 44, no. 5. Dysphania spp. Indian agriculture has registered impressive growth over last few decades. The lowest concentration level that significantly inhibited germination and seedling growth in L. esculentum was lower (0.5%) for ethanol crude extract than that (5.0%) of aqueous crude extract. Fig. Only fractions 4 and 5 inhibited seed germination in L. esculentum at 25% concentration. 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]. Organic C and exchangeable K in Kano State and available Cu in Bauchi State were positively related to maize grain yields. 1189-1197, August 2008. 4. Distribution maps given for the eight species which are currently most important in the Complex. 4. Differences in species diversity (in terms of richness) were observed between biogeographic sub-regions for all plant groups, while differences between forest conditions were found for tree and epiphyte species only. It is one of the world's most successful invasive plants, occurring all over the world, Elucidate coastal foodwebs for conservation and management, The Philippine blubber jellyfish Catostylus sp. Data on Striga population, number of crops attacked by Striga, and host reaction were subjected to analysis of variance. ABSTRACT: Chromolaena odorata or siam weed is regarded as one of the most harmful weeds present on earth. The Striga population in all crop fields differed significantly among communities in both states. 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. Thanks, Copyright © 2020  KITE E-Learning Solutions |  odorata can be a viable and cheap source for antifungal formulations though the efficacious dosage may be higher than that of Nystatin. Sixty-four cowpea fields in Kano State were sampled and 49 in and Bauchi State. Cirsium arvense: Canada thistle. 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. followed by fruit (17 spp. 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. mangrove species and four species nails and orchids. 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. d’Ivoire,” Netherlands Journal of Agricultural Science, vol. No relationship was observed between age of the farmers and fruit diversity, while education, family size, area of homestead, area under fruit have low and non-significant positive relationship with the fruit diversity. Striga emergence, number of crop plants attacked by Striga, host reaction, and soil properties were measured from five 2 m × 2 m quadrats in each farmers’ field. In Bauchi State, S. hermonthica was negatively related to total N and organic C and was positively related to exchangeable Ca and latitude. 246-254, August 2005. Only 17 fruit, 13 timber, 17 vegetable and 2 spices species were found in all region. The Chinese banyan (Ficus retusa) dominate this ecosystem. Subsistence farmers usually cannot afford, to hire laborers, so productive farming time is lost to weeding, infested the three Provinces of the Zamboanga Peninsula, because its life history is supported by soil and climatic, properties of the area, and the occurrence of plantation, the production of large quantities of propagules and its, incorporating weed management in farming system, harvesting and exploiting positive attributes (e.g. 2009;Li et al. It has been reported to be the most problematic invasive species within protected rainforests in Africa. Summary 1. 3&4, pp. Depending on chromolaena density, soil type and aspect, grasslands can be rehabilitated and managed in multiple states, namely as grassland, savanna or forest communities. Sterilization of these soils eliminated their inhibitory effect. Except for very tall species like coconuts and, the sampling sites was acidic which ranged from, Mean organic matter was fairly low (0.9 - 1.62%). It is likely that C. connexa will continue to disperse further with time. collected by using questionnaires, focused group discussion and field observations. 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. m, largest colonies found in Southern sites (Fig. Mulching slashed vegetation, as a land preparation practice, was also consistently better at reducing weed densities than burning the slashed vegetation. The 0.5% ethanol crude extract also reduced the mitotic index in Allium cepa (onion) root tips. 2. 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. aqueous and alcohol crude extracts from leaves of Chromolaena, ecosystems: weed or fallow plant?” Applied Ecology and. Associated with the management of protected areas, it is necessary to CAPS Chromolaena, however, has recently become a key component of woody plant succession in subtropical grasslands. forest ecosystems obtained a larger amount, namely 77 plant species and four species nails and orchids. The location of, , and the area occupied by the species at these, Loam soil type was common in all sites. 1, pp. 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.
