Abstract
Rapeseed-mustard crops are attacked by a wide array of insect pests and mustard aphid, of which Lipaphis erysimi Kaltenbach is the most destructive one. It causes heavy losses in terms of quality and quantity. Bakhetia and Sekhon (1989) reported 35.0 to 73.3 per cent losses in yield in different agroclimatic regions with a mean loss of 54.2 per cent on all India basis. High incidence of this pest can cause complete loss of the crop. Among various practices recommended for the management of this aphid, use of chemical insecticides is a quite common practice among farmers. But their use particularly at flowering stage of the crop, inter alia results into serious losses of pollinators and natural enemies. The present investigations were therefore carried out to see the effect of the insecticides applied in the soil prior to flowering succeeded by post bloom sprays in order to avoid the spraying during peak bloom period and to perceive the effect of soil applied chemicals and post bloom sprays on the yield and yield contributing traits of the crop as well as on the infestation of mustard aphid, Lipaphis erysimi . The results of two years studies conducted during rabi 2009-10 and 2010-11 revealed that the number of primary and secondary branches/plant, seeds/siliqua, thousand seed weight and seed yield were significantly higher under the pre flowering treatment of carbofuran succeeded by post bloom spray of cypermethrin (T 2 ). This treatment also provided the best control of Lipaphis erysimi as significantly least dried siliquae/plant (3.03 and 2.09) were recorded during the two years observations. This treatment was followed by preflowering application of carbosulfan succeeded by post bloom spray of cypermethrin (T 4 ). In case of unprotected crop, significantly higher numberof dried siliqua/plant (16.70 and 16.73) were recorded during the two years of observations.
