Abstract:
In-vivo management of diamondback moth (DBM) larvae on cabbage crop by Bracon hebetor through Bracocards was evaluated in the research field of Pt. KLS College of Horticulture and Research Station, Rajnandgaon during 2016-17 and 2017-18. The release of cocoons of Bracon hebetor @ 8500 cocoons ha^-1 (85 Bracocards) at 7, 12, 15 and 20 DAR was recorded as the most effective management practice with minimum larval population of 3.20, 2.43, 1.40 and 1.13 larvae plant^-1 while maximum larval population were recorded under control with 5.75, 5.68, 5.88 and 5.78 larvae plant^-1, respectively. Bio-control agents along with using different package of practices like timely sowing, use of tolerant varieties, intercropping and botanicals can be used to reduce the population pressure and minimize the pesticide application for an eco-friendly management of diamondback moth menace.
