Typically, they are distributed worldwide and parasitize nearly every species of higher plant. Due to their endoparasitic way of living and feeding, root knot nematodes disrupt the physiology of the plant and may reduce crop yield and product quality and, therefore, are of great economic importance and make control necessary. Field studies were conducted in 2008 and 2009 to determine yield loss of cowpea (cv. ART98-12) due to natural infestation by M. incognita using Carbofuran 3G at 2kg a.i./ha and untreated as check. The yield of cowpea was found to be higher with the application of nematicide-Carbofuran 3G at 2kg a.i. /ha. The percentage increase over control was 39.0 and 33.0% in the years 2008 and 2009, respectively. A significant reduction in the yield of cowpea in untreated plots was mainly attributed to direct damage of the root system by the feeding of root-knot nematode, M. incognita . The root knot nematode population in carbofuran treated plots was significantly lower than in check in the two years, also at harvest. In the check the nematodes reproduced many folds during the cropping season. Higher nematode population in the untreated check decreased plant growth and consequently reduced the number of harvested seeds and other agronomic parameters.","PeriodicalId":11566,"journal":{"name":"Electronic journal of environmental, agricultural and food chemistry","volume":"78 1","pages":"2042-2048"},"PeriodicalIF":0.0,"publicationDate":"2011-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83941505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Antioxidant and antibacterial activities as well as chemical composition of organic extracts obtained from different cultures were examined. The amounts of total carotenoids, chlorophylls-derived and phenolic compounds were associated inversely with concentration of nitrogen in growth media. The antibacterial results showed that all S.maxima extracts exhibited great potential antibacterial activities against six bacterial strains with inhibition zones ranged 7 - 18 mm and MICs values ranged 30 - 40 µg/mL. Also, all S.maxima extracts possessed potent antioxidant properties as comparable to commercial antioxidants. The chromatographic analyses of Spirulina organic extracts with TLC and HPLC showed that carotenoids, chlorophyll-derived and phenol compounds were presence as main constituents and their quantities was significantly changed dependant on culture conditions. Thus, it could be suggested that the Spirulina is useful bio-system for production bioactive compounds possess an antioxidants and antimicrobial principles and as natural pigments.","PeriodicalId":11566,"journal":{"name":"Electronic journal of environmental, agricultural and food chemistry","volume":"61 9","pages":"1113-1126"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91465923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Better antifungal activity was observed with the extracts of Valeriana wallachi, that showed excellent inhibitory activity against Helminthosporium sp. (96.15%) followed by Shilajit extract against Alternaria cajani (95.12 %) and Helminthosporium sp. (95.00 %) at concentration of 5000 �og/ml. Among different fungi tested Bipolaris sp. and Fusarium were found to be more sensitive to crude extract when compared to others. The increase in the production of phenolics in the extract can be correlated with the induction of resistance in treated plants against phytopathogenic fungi. HPLC analysis of the crude extract of medicinal plants showed four different Phenolic acids (Tannic acid, Gallic acid, Ferulic acid and Caffeic acid). The results of the study provide scientific basis for the use of the plant extract in the future development as antioxidant, antibacterial, antifungal and anti-inflammatory agent.","PeriodicalId":11566,"journal":{"name":"Electronic journal of environmental, agricultural and food chemistry","volume":"98 1","pages":"218-229"},"PeriodicalIF":0.0,"publicationDate":"2007-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81271754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
