abstract
In Nagarkurnool district of Telangana state the Cotton crop is being cultivated in 1,19,059 ha mainly in shallow soils which are poor in fertility as well as water holding capacity. The farmers don’t have the sufficient knowledge on IPM components to manage the pests and diseases in Cotton crop. To overcome these problems KVK, Palem has been organized Front line demonstration on promotion of IPM in Bt cotton in 10 locations every year from three years i.e. 2016-2018. Regular monitoring, Seed treatment with Pseudomonas fluorescence @ 30g/kg seed, stem application by using rolling stem applicators with monocrotophos 36% SL @ 1: 4 ratio at 30, 60 and 70 days intervals and installation of yellow sticky traps was reduced the incidence of sucking pest complex up to 25-30%, erecting of pheromone traps 8/acre at flowering to square formation stage, bird perches @ 20/acre, Spraying of Azadiractin 1500ppm @ 5ml/litre of water at boll formation stage and need based spraying of insecticides the incidence of Pink bollworm (PBW) is below the ETL up to first picking, but after the first picking due to prolonged dry spells, poor plant vigour the PBW flared up. The results revealed that in frontline demonstration on IPM in cotton an average three year yield recorded was 20.38 q/ha as compared to the farmer’s practice which was 18.33q/ha with the average benefit cost ratios are 1:1.33 and 1:1.09 and with net returns of 24,691/- compare to farmer practice 7682/- respectively. However, with the IPM module five pesticidal sprays were reduced by saving an amount of 6000/-.
