Abstract
Comparative laboratory and field efficacy of certain indigenous plant extracts were tested against Mustard aphid, Lipaphis erysimi (Kalt.) on cabbage var. ‘Pride of India’. Among the various aqueous extracts evaluated in the laboratory, seven plant extracts from Melia azedarach, Jatropha gossypifolia, Agerarnm couyzoides, Lantana camara, Murraya kaenigii, Acorus calamus and Artemisia nilagirica sprayed at 5% concentration were found to be significantly superior to the rest in reducing the aphid population. Thus, field efficacy of ether extract of these seven plant species each at 0.5% concentration was tested with Nimbecidine and Dichlorvos at 0.3% and 0.05% concentrations, respectively. The population of L. erysimi was significantly different among the treatments at all the time intervals under observation. But, Dichlorvos gave the best control with a record of 4.67 aphids/plant as against 31.67 aphids/plant in untreated control. Dichlorvos was closely followed by Nimbecidine with a record of 7.84 aphids/plant. Among the various ether extracts, the maximum protection was provided by M. azeilarach with minimum aphid population of 11.25 per plant which was at par with the population recorded on the plots treated with J. gossypifolia, A. rzilagirica, A. conyzoides, and M. koenigii. The maximum yield (18.83 t/ha) was recorded in the plots treated with Dichlorvos as against untreated control (12.25 t/ha), followed by Nimbecidine(17.17 t/ha), M. azedarach1(15.83 t/ha) and J. gossypifolia (15.00 t/ha).
