Abstract

During the rabi seasons from 2017 to 2020 in the valley and foothill regions of Imphal, Manipur, a study was conducted to design and test three different organic insect pest management modules M1, M2 and M3 for cabbage and cauliflower. The focus was on three major pests: cabbage butterfly, diamondback moth, and cabbage aphid. Module three (M-3) emerged as the most effective strategy, incorporating various organic practices. This included seed treatment with Trichoderma harzianum at 10g/kg seed and soil drenching in nursery plots at 25g/100 m2, intercropping with mustard, application of anonnin extract at 5 ml/litre, Spinosad 45% SC (biopesticide) at 3ml/10 litres, and Verticillium lecanii at 10 ml/litre. Additionally, the module incorporated the installation of yellow sticky traps for aphids and pheromone traps for diamondback moths for monitoring and mass trapping. The results indicated that Module 3 performed well than other modules and the control group in reducing insect pest incidence on cabbage and cauliflower with the number of cabbage butterfly ranging from 0.07 to 0.11, in both cabbage and cauliflower, where as 0.06 to 0.04 in case of Diamond back moth and 0.21 to 0.47 number of cabbage aphid per square inch leaf area with B:C ratio of 1:12.4 and 1:12.7 for cabbage and 1:6:39 and1:6.41 for cauliflower at lamphel and lanol fields, respectively.  Moreover, it contributed to an increased yield, demonstrating its superiority in organic insect pest management for both valley and foothill regions. This underscores the effectiveness of a holistic and integrated approach to pest management in organic farming practices.
