Comparative evaluation of different modules for the management of borers, Earias vittella and Helicoverpa armigera in okra

The present investigation entitled “Comparative evaluation of different modules for the management of borers, Earias vittella and Helicoverpa armigera in okra ” during kharif, 2024 revealed that among five different pest management modules, the chemical module (M4) proved to be the most effective in reducing the population of Earias vittella and Helicoverpa armigera, with overall mean of 3.99 larvae of E. vittella per five plants and overall mean of 1.46 larvae of H. armigera per five plants after three sprays followed by farmerʼs routine module (M5), IPM module (M1) and BIPM module (M2). Organic module (M3) was the least effective module with maximum number of overall mean of 4.95 larvae of E. vittella per five plants and overall mean of 2.13 larvae of H. armigera per five plants after three sprays which were applied at 30,45 & 60 days after sowing. The percent shoot and fruit damage caused by borer complex on okra show that the minimum shoot and fruit damage was recorded in the chemical module (M4) with an overall mean of 6.58 percent shoot damage and overall mean of 5.01 percent fruit damage followed by farmerʼs routine module (M5), IPM module (M1) and BIPM module (M2). The maximum number of shoot and fruit damage was recorded under organic module (M3) which was 12.51 overall mean percent shoot damage and 10.09 overall mean percent fruit damage. The maximum benefit cost ratio was recorded in organic module (M3) with ratio of (1:13.34) followed by farmerʼs routine module (M5) with ratio of 1:12.72. The benefit cost ratio of IPM module (M1) was 1:11.21 and in chemical module (M4) it was 1:9.18. The minimum benefit cost ratio was recorded under BIPM module (M2) which was 1:5.78.
