Abstract:
The field trail was conducted at CRC on Sardar vallabhbhai Patel University of Agriculture & Technology Meerut, during Rabi 2015-16 on Indian mustard (Brassica juncea) variety Urvashi. Among the seven treatments including control plot. The aphid population were found on 10 apical twigs/plot each of 10 cm length ranges from 8.33 to 38.33 aphids/plant. The minimum population (8.33 aphids/plant) was recorded from acephate 75 SP @ 350g a.i./ha compared to control and also the maximum yield was obtained with treatment acephate 75 SP @ 350g a.i./ha giving 16.35 q/ha and was found superior over rest of all other treatments whereas the maximum gain in net income of Rs. 22560/ha was found from acephate 75 SP @ 350g a.i./ha. Cost benefit ratio of the treatments showed that imidachloprid 17.8 SL @ 20g a.i./ha ranked first indicating the maximum B:C Ratio (1: 10.36).
