Herbicidal Activity of Aqueous Extracts of Cirsium arvense and Ageratum
conyzoides Against Weeds of Wheat
Abstract:
Aqueous root, stem and leaf extracts of 0, 5, 10 and 15 % w/v of an allelopathic plant species viz. Cirsium arvense were evaluated for their potential to control germination and seedling growth of two weed species, Phalaris minor and Poa annua. All the aqueous extracts reduced germination in two test weeds. However, effect was insignificant statistically. Shoot length in P. minor was reduced significantly by 10 % stem extract while shoot length in P. annua remained unaffected by all the extracts. Root length was more susceptible to allelopathy and was reduced significantly in both the test weed species. In a similar experiment germination of P. minor and Medicago polymorpha was significantly reduced by 15 % leaf extract of Ageratum conyzoides. In both the test weeds, response of root and shoot length to aqueous extracts of A. conyzoides was similar to the response of test weeds to aqueous extracts of C. arvense in first experiment.
