Evaluation of different IPM modules against pest complex of Chilli (cv. Byadgi dabbi)

Abstract

Insect pest management has been dominated by the use of synthetic pesticides since its discovery. This awaken the world on dangers pose by the synthetic chemicals. Since then, the search for alternative pest control such that new molecules and bioagents, which is safe and effective, has been prioritized. An investigation on evaluation of different IPM modules for the management of pest complex in chilli (Cv. Byadgi dabbi)revealed that M-III was most effective module against thrips, mites and Helicoverpa armigera Hubner.Higher chilli yield 12.36 q/ha with 36.57 % increase over untreated control was observed in M-III (Root dip with imidacloprid 17.8 SL @ 0.5 ml/l for 30 min. at the time of transplanting + Acetamiprid 20 SP @ 0.2 g/l + Fenpropathrin 30 EC @ 0.5 ml/l + Diafenthiuron 50 WP @ 1.0 g/l + Spiromesifen 240 SC @ 1ml/l + Spinosad 45 SC @ 0.2 ml/l + Rynaxypyr 18.5 SC @ 0.2 ml/l) followed by M-II (Application of neem cake @ 2.5 q/ha at the time of sowing + Growing one row of marigold as a trap crop and two rows of maize as barrier crop + Root dip with imidacloprid 17.8 SL @ 0.5 ml/l for 30 min. at the time of transplanting + Azadirachtin 10,000 ppm @ 1.0 ml/l.+ Lecanicillium lecanii (1x108 CFU/g) @ 5 g/l + Diafenthiuron 50 WP @ 1.0 g/l @ 0.5 ml/l + Rynaxypyr 18.5 SC @ 0.2 ml/l) was equally effective in recording the yield of 11.84 q/ha with 33.78% increase in yield over control. Considering the result, M-I in comparison with M-III and M-II however appeared to be a quite promising strategy.
