Bioefficacy, insecticidal spray schedules, mustard aphid


The bioefficacy of five insecticidal spray schedules against aphid, Lipaphis erysimi Kaltenbach in mustard was evaluated a field experiment in conducted at Instructional Farm, College of Agriculture, Junagadh Agricultural University (JAU), Junagadh during Rabi 2012-13 and 2013-14. The results revealed that schedule 4 consisting of flonicamid 0.02 per cent at seedling stage, flubendamide 0.014 per cent at pre-flowering stage, azadirachtin 0.15 per cent at 50% flowering stage and acephate + fenvalerate 0.028 per cent at 50% pod formation stage was significantly. The most effective treatment which recorded lowest aphid index (1.1) over stage of the crop and year, whereas the schedule S3 (1.4 aphid index) proved next better effective in comparison to control schedule S6. The highest grain yield was found in schedule S4 (1302 kg/ha) followed by S3 (1218 kg/ha) and schedule S5 (1172 kg/ ha) yield. Significantly the lowest grain yield was recorded in untreated control schedule S6 (500 kg/ha). It showed highest gross realization in schedule S4 (29674 Rs/ha) followed by schedule S3 (26566 Rs/ha). The schedule S2 generated highest ICBR ratio (1:6.7) followed by schedule S3 (1:6.3) and schedule S4 (1:6.3) whereas, schedule S1 (1:3.1) gave significantly lower ICBR than other schedules. Thus, any one of the above effective and economical insecticidal spray schedule can be suggested for the control of mustard aphid.
