Synthesis. The Striga gesnerioides population was negatively related to cowpea grain yield. A three-stage sampling technique was used to select communities and fields for sampling in targeted Local Government Areas (LGAs) in both states. 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. 44, no. ), timber (16 spp.) 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. Environmental Research, vol. 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. Chromolaena odorata es un arbusto de la familia del girasol nativo de Norteamérica, desde Florida y Texas a México y de la Indias Occidentales. 6, pp. Cirsium arvense: Canada thistle. 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. 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. Host damage was more severe in Danmako. 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. d’Ivoire,” Netherlands Journal of Agricultural Science, vol. Taxonomy of the Philippine blubber jellyfish Catostylus sp. King & H. Rob. Alien clearance is an essential and invaluable management tool. collected by using questionnaires, focused group discussion and field observations. The 0.5% ethanol crude extract also reduced the mitotic index in Allium cepa (onion) root tips. The nomenclature of Chromolaena odorata (L.) R.M. 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. of, Management of Chromolaena odorata and Mikania mi, Chromolaena odorata: preliminary studies on the use of the gallform. Among them 30.9% fruits, 29.09% timber, 34.54% vegetables and 5.45% were spices species. 14, no. 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]. 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. Insights into the opportunities and the challenges of recruiting trees for the rehabilitation of these forests are much needed. Striga hermonthica incidence in maize fields ranged from 0 to 100% in Kano State and this varied among communities and LGAs. (Copasanda) which an invasive species. In sorghum fields, the highest population of Striga was recorded in Lame at Toro LGA in Bauchi State. a common characteristic for many weed species [10]. Chromolaena odoratais a serious invader of many crop lands, plantations, wastelands, rangelands, and reforested areas – infesting up to about 500,000 hectares (Aterrado & Bachiller 2002, Acasio 2003) and is considered one of the seven worst invasive species in the Philippines (Joshi 1989). 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. Biological control has a major role in rehabilitating grassland to secondary forest or in forest ecosystems that have become invaded. of the Second International, Workshop on Biological Control and Management of Chromolaena. 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. Robins. highest Important Value Index (IVI) in the tree category. 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. Galls start to appear within 12-15 days after oviposition. Proceedings of the Eighth International Workshop on Biological Control and Management of Chromolaena odorata and other Eupatorieae, Nairobi, Kenya, 1-2 November 2010. Indeed, the introduction of non-indigenous species into protected areas is a direct threat to conservation. 13–27, January 2001. flora, in a rain forest zone, south-west Cote d’Ivoire,” Journal of. In conclusion, farmers’ perception on soil quality was inconsistent with the result of laboratory soil analysis, which revealed the poor fertility status of soils in the communities studied. 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. The Philippines is both a megadiversity country and a global biodiversity hotspot. 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. Predictions made for the current condition was subsequently projected for the years 2050 and 2100 for both moderate and extreme climate change scenarios. climate,” Weed Research, vol. U.S. D. Madulid, A Pictorial Encyclopedia of Philippine Ornamental Plants. Chromolaena odorata is one of the most important invader species in the savanna biome in South Africa. Both are likely to reduce their potential distribution areas in the future climate, where moisture availability is a key factor for their range expansion. The diversity patterns of three major plant groups were assessed: (1) trees (trees and palms), (2) herbs (grasses, shrubs, forbs, ferns), and (3) epiphytes (climbers and epiphytes), by determining the changes in compositional and species richness patterns in two forest conditions, i.e., remnant forests and exotic tree species-based reforested areas, in active forest over limestone quarries in the Luzon and Mindanao biogeographic sub-regions of the Philippines. Only fractions 4 and 5 inhibited seed germination in L. esculentum at 25% concentration. Twenty seven fruits, 23 timbers, 17 summer vegetables and 12 winter vegetables species were identified. Chromolaena invades subtropical grasslands that are not burnt regularly. 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 … Herbaceous aliens were not surveyed. J. Slaats, W. Van Der Heiden, C. Stockmann, M. Wessel, and B. E. T. F. Witkowski and M. Wilson, “Changes in density, biomass, seed. 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. Associated with the management of protected areas, it is necessary to CAPS Many efforts are being made for the control of this weed. 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. Join ResearchGate to find the people and research you need to help your work. It has been utilized in the traditional medicinal systems for its … 8, no. Cleome serrulata: Rocky Mountain bee plant. ... (Asteraceae), known locally as hagonoy (Oerke et al. 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. odorata, Bogor, Indonesia, 1991, pp. 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. 220, no. forest, coastal forest and mangrove forests. 4. However, flavonol content was highest in the aqueous extract of E. odoratum followed by ethanol extract of A. boonei. 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. The traditional homestead fruit production & mangement system and low quality plant sapling is the main problem which need specific attention. The country has recorded highest productivity (25.4 tonnes/ha) in the case of grapes in the world. List of various diseases cured by Chromolaena Odorata. 96, no. This study investigated the in vitro antioxidant activity and phenolic content of aqueous and ethanol extracts of Alstonia boonei and Eupatorium odoratum leaves. which inhibit native plants,” Journal of Ecology, vol. 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. Siamweed. 3. 8-10. Some sites where the gall fly was reported were up to 400 km from the initial release sites around Davao, Mindanao. 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. 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. Number of vegetable species was found the highest (19 spp.) The antioxidant capacity of the extracts were assessed through diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activity, ferric reducing antioxidant power (FRAP) and reducing power (RP). Zamboanga del Sur, Philippines on January 24, 1973. 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. Depending on chromolaena density, soil type and aspect, grasslands can be rehabilitated and managed in multiple states, namely as grassland, savanna or forest communities. It is also used as a reforestation species in RPL. 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. The results of the study on three of these ecosystems get a number of Ecology, vol. In ecosystem mangrove, recorded only eight true 1). 3. Big triangles represent plant species (see Table 1 for species. Maximum Entropy (Maxent) was applied to assess their habitat suitability, risk area identification and shifts in range sizes. 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. 1. Distribution maps given for the eight species which are currently most important in the Complex. 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. It reduces vegetation heterogeneity in grasslands, savannas and forests. 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.
