In: Po-Yung Lai et al. Soil, pH is not a limiting factor in the germinati. 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). Essentially all sites have already been invaded C. odorata, and the area occupied … 14, no. Dysphania 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). 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. 220, no. In Bauchi State, the highest population of S. gesnerioides occurred in Gar at Ganjiwa LGA. Chromolaena odorata, along a 15 year chronosequence,” Plant Ecology. Canonical Correspondence Analysis (CCA) triplot showing the, sampling sites. The phenolic and flavonoid contents of extracts of E. odoratum were higher than that of A. boonei extracts. 8-10. 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. The Striga population in all crop fields differed significantly among communities in both states. Thanks, Copyright © 2020 KITE E-Learning Solutions | 4. Organic C in Kano State and available P in Bauchi State where negatively related to sorghum grain yield. 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 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. (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. 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 distribution of Cecidochares connexa (Macquart), a biological control agent of the invasive plant Chromolaena odorata (L.) R.M. In both states > 90% of cowpea fields had coarse textured soil. These discrepancies in climatic dependencies allowed both for a harmonious distribution, i.e., inhabiting in regions not utilised by other. of the. It was first recorded in the Philippines on the Zamboanga Peninsula in the 1960s through traders from Borneo (Codilla & Metillo 2011). There was a dose-dependent increase in FRAP and RP capacity in all the extracts. Its negative impacts on agriculture and biodiversity are clear. Depending on chromolaena density, soil type and aspect, grasslands can be rehabilitated and managed in multiple states, namely as grassland, savanna or forest communities. In Bauchi State, these two parameters ranged from low (Ca: < 2; Mg: < 0.3 cmol/kg) to high. 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. However, on marketing front, Indian agriculture is still facing the problems such as low degree of market integration and connectivity, accessibility of reliable and timely information required by farmers on various issues in agriculture. path method. 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. In sorghum fields, the S. hermonthica population had a negative relationship with organic C, total N, latitude, available Fe, and exchangeable Ca and was positively related to available P and exchangeable Mg in Kano State. 18, no. We investigated the role of a native generalist soil pathogen through which a non-native invasive plant species may suppress naturalized/native plant species. Of these, 21 species were categorized as threatened species. He was conferred, Graduate Diploma of Science in 1992 and Doctor of, Philosophy (zoology) in 1995 at the University of. 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 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. 1. Uses, Benefits, Cures, Side Effects, Nutrients in Chromolaena Odorata. In sorghum fields, the highest population of Striga was recorded in Lame at Toro LGA in Bauchi State. was determined around the three main islands-Luzon, Visayas, and Mindanao-in the Philippines. 152, no. Siamweed. In both states, the Striga population was negatively correlated with maize, sorghum, and cowpea grain yields. codes). 949-959, September 1983. L. S. Koutika, and H. Rainey, “Chromolaena odorata in different. It was first found in Australia in 1994, when several large infestations were spotted along the Tully River and at Bingil Bay near Mission Beach in far northern Queensland. 13–27, January 2001. flora, in a rain forest zone, south-west Cote d’Ivoire,” Journal of. Lastly, the MaxEnt model exemplifies that the most suitable predicted conditions for invasive alien plant species are at the edges of boundary and buffer zones. Visual observations showed that the gall fly is having some impact on C. odorata, as evidenced by dead branches and stems. 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. Striga gesnerioides incidence was >95% in both states. 2003;Sa´nchez-Blanco et al. habitats and was conspicuously absent in dense shady forests, . The distribution of C. odorata in South Africa extends further south than predicted by the model based on Asian and American distribution records. 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. which inhibit native plants,” Journal of Ecology, vol. The prevalence of T. procumbens in central regions of India could demonstrate its greater dependencies on precipitation seasonality and radiation than that on temperature. 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. 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. 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 … But, it is a different case in Indonesia. 105-112. 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. On average, a farm owner, pays about US$5 (August 2011 exchange rate: PhP42.00 to, out from their farms. 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. bioactiv, compounds , fallow plant for acidic soils ) of the, We deeply thank the Philippine Commission on Higher. Some sites where the gall fly was reported were up to 400 km from the initial release sites around Davao, Mindanao. It reduces vegetation heterogeneity in grasslands, savannas and forests. 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. The country has recorded highest productivity (25.4 tonnes/ha) in the case of grapes in the world. forest ecosystems obtained a larger amount, namely 77 plant species and four species nails and orchids. 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. Usually, chromolaena odorata can be found on the height from 1000 to 2800 above the sea level. The methods used in data collection is an analytical method of vegetation with terraced 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. Chromolaena odorata, Durban, South Africa, 2002, pp. The gall fly, Procecidochares … biodiversity monitoring. In this study, we examined the molecular mechanisms by which Siam weed extract (SWE) affected hemo … 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. In Kano State, 194 (maize: 33; sorghum: 161) fields were sampled and 168 (maize: 100; sorghum: 68) fields in Bauchi State. and other plant species growing around it, and, threatens subsistence cattle farming in West Timor, at the five selected sites. Also known as Siam weed, it forms dense stands that prevent the establishment of other plant species. ... Eupatorium odoratum, also known as Chromolaena odorata (L.), is a wildly growing free standing shrub from the family of Asteraceae. 3&4, pp. However, indigenous people have harnessed several benefits of the plant, making management strategies less straightforward. A total of 105 sites in 17 localities with C. odorata were surveyed for the presence of C. connexa. 4. 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. at the same institution from 1998 to the present. Alien clearance is an essential and invaluable management tool. There are studies on its insecticidal properties, but its potential as control to housefly is not yet explored. 2. In Kano State, maize and sorghum fields were dominated by coarse (maize: 38.7%; sorghum: 52.0%) and medium (maize: 61.3%; sorghum: 48.0%) textured soil. Education for the scholarship grant to LT Codilla, JL Codilla for the help in field sampling. 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. 1, pp. Chromolaena odorata in Ghana,” in Proc. 2005; ... Introducido en regiones tropicales de Asia y África, donde se ha convertido en invasora. Sparse to moderate infestations with more than 30% grass cover are killed by fire. aqueous and alcohol crude extracts from leaves of Chromolaena, ecosystems: weed or fallow plant?” Applied Ecology and. A three-stage sampling technique was used to select communities and fields for sampling in targeted Local Government Areas (LGAs) in both states. 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. 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). followed by fruit (17 spp. 137-139. ABSTRACT: Chromolaena odorata or siam weed is regarded as one of the most harmful weeds present on earth. Dactyloctenium radulans: button grass, but only when growing in high-nitrogen soil, such as in stockyards. More recent surveys have identified infestations in the Townsville-Thuringowa, Mossman and Mt Garnet areas. 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. Ajmiriganj upazila of Hobigonj district of Bangladesh was the study area. Several gaps in our database concerning ecophysiology of tropical tree crops are indicated, major advances are examined, and needs of further researches are delineated. Agricultural marketing occupies an important place particularly in the context of the new liberalization process and value addition requirements of the agriculture sector. The Asian tree, Melia azedarach, is considered the second most important alien species invading the area. Sterilization of these soils eliminated their inhibitory effect. The location of, , and the area occupied by the species at these, Loam soil type was common in all sites. and spices (3 spp.). 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. These data are important for policy-forming and informing policy-makers that alien invasion and removal are critical for biodiversity conservation management. Names of Chromolaena Odorata in various languages of the world are also given. 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. 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). in the group of trees. 3. 1. Natal,” Bothalia, vol. 246-254, August 2005. The herb/shrub species, Chromolaena odorata is identified as a primary factor for the difficulties of tree recruitment. The nomenclature of Chromolaena odorata (L.) R.M. In Bauchi State, S. hermonthica incidence in maize and sorghum fields was 100% in all the communities. 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. Total phenol, flavonoid and flavonol content of the extracts were estimated to determine the levels of phenolics in the extracts. 96, no. Seedling recruitment data from soil seed banks are interrogated with Repeated Measures Analyses of Variance, and these data show that, first, tree life forms are not significantly greater than other life forms, and that in fact tree life forms are the minority in the conditions of the examined agricultural land uses. Among them 30.9% fruits, 29.09% timber, 34.54% vegetables and 5.45% were spices species. 6, pp. Big triangles represent plant species (see Table 1 for species. This study investigated the in vitro antioxidant activity and phenolic content of aqueous and ethanol extracts of Alstonia boonei and Eupatorium odoratum leaves. 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. 5. © 2008-2020 ResearchGate GmbH. 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. 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. 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. C. odorata from the three provinces of Zamboanga Peninsula is very similar with the AWA and the Central and South American biotypes. Only 17 fruit, 13 timber, 17 vegetable and 2 spices species were found in all region. These findings may help explain the wide invasion of C. odorata in the Zamboanga Peninsula. Microcomputer Power, 2002. growth and reproduction in Chromolaena odorata,” in Proc. The foodgrain production has increased from 51 million tonnes (MT) in 1950-51 to 250 MT during 2011-12 highest ever since independence. ... (Asteraceae), known locally as hagonoy (Oerke et al. 40, no. 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). Mulching slashed vegetation, as a land preparation practice, was also consistently better at reducing weed densities than burning the slashed vegetation. J. K. Francis, Chromolaena odorata (L.) King & H.E. The suppression of seedlings in dense infestations requires chemical control until grass cover is sufficient to effect uniform burning. 8, no. The results emphasize the importance of understanding forest recovery in disturbed ecosystems. Note: Kindly Login or Register to gain access to this article. Available Cu ranged from 1.0 to 2.55 mg/kg in Kano State and from 0.49 to 2.91 mg/kg in Bauchi State. m, largest colonies found in Southern sites (Fig. Cleome serrulata: Rocky Mountain bee plant. The revised model reduces the estimated potential distribution of C. odorata, particularly in terms of the poleward and inland extents of suitable climates. richness, Relative prevalence and Species diversity. 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. 1, pp. Chromolaena density affects grassland species composition, with dense stands in grassland being monospecific. 446-458, factors on seed germination and emergence of Chromolaena odorata in, coconut plantations in Sri Lanka. 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. Ecology, vol. Indian agriculture has registered impressive growth over last few decades. 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. Chromolaena odorata . Windows appear on the gall one month after oviposition and attain a maximum width of 9.7 mm and length of 13.7 mm. The crop physiological responses to environmental. of the Second International, Workshop on Biological Control and Management of Chromolaena. It has been introduced into the tropical regions of Asia, Africa and the Pacific, where it is an invasive weed. Chromolaena odoratais a perennial shrub native to tropical America. Country has emerged as the world's largest producer of mango, banana, coconut and the second largest producer and exporter of tea, coffee, cashew and spices. Sterilization of these soils eliminated their inhibitory effect. 1994, Sinohin & Cuaterno 2003. Cirsium arvense: Canada thistle. Join ResearchGate to find the people and research you need to help your work. South Africa: how well do we understand the ecological impacts?”. Biological control has a major role in rehabilitating grassland to secondary forest or in forest ecosystems that have become invaded. forest, coastal forest and mangrove forests. Invasive plants have been shown to escape inhibitory soil biota in their native range and to inhibit soil biota in their invaded range, but our results indicate that the impacts of Chro-molaena are due to the exacerbation of biotic interactions among native plants and native soil biota, which is to our knowledge a new invasive pathway. 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. 45, no. Associated with the management of protected areas, it is necessary to CAPS However, a more robust study regarding its presence in other parts of the country and its effectiveness as a biological control agent is needed.  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. species on tree recruitment,” Applied Geography, vol. 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 … 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. Forest succession in grassland also ceases once chromolaena becomes thicket-forming. zoology in Mindanao State University Marawi City, Philippines in 1994, and Master of Science, Education in Mindanao State University-Iligan. of, Management of Chromolaena odorata and Mikania mi, Chromolaena odorata: preliminary studies on the use of the gallform. (Authors' abstract) SUBJECTS Biology Chromolaena odorata Biotype The existing marketing system needs to be updated through improvement in skills, knowledge, attitude etc. 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. 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. Indeed, the introduction of non-indigenous species into protected areas is a direct threat to conservation. In Kano State, an average of three maize plants/m2 was attacked by S. hermonthica in Danmako, Bebeji LGA and Burji, Doguwa LGA. 1). odorata can be a viable and cheap source for antifungal formulations though the efficacious dosage may be higher than that of Nystatin. Differences between the plots of with and without invasive alien plant species in physicochemical factors indicate that most of the physicochemical factors have a significant difference between plots of with and without invasive alien plant species except percent slope, hill shade, and aspect. ... Indonesia, Philippines, Western Caroline Islands, Mariana Islands and India. Chromolaena odorata is one of the most important invader species in the savanna biome in South Africa. Proceedings of the Eighth International Workshop on Biological Control and Management of Chromolaena odorata and other Eupatorieae, Nairobi, Kenya, 1-2 November 2010. contributes 28 per cent of agricultural GDP. 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. W. van Wilgen, “Invasive alien plants in, R. C. McFadyen, and B. Skarratt, “Potential distribution of, I. Analysis of Vegetation Island Sempu conducted to determine the current condition of the biodiversity existing Second, the analyses indicate that the natural recruitment of tree seedlings for tree rehabilitation confronts enormous competition from non-tree species. To understand the use of Chromolaena odorata in different agricultural systems and ecosystems, findings of several scientific studies conducted in different areas have been assessed in this review paper. Maximum Entropy (Maxent) was applied to assess their habitat suitability, risk area identification and shifts in range sizes. 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. 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. 1, pp. vegetation in the area of CAPS. San Beda College Manila Philippines email@example.com Abstract—Chromolaena odoratahas been known as nuisance weed in agricultural farms. 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. 2.
