Evaluation of different pest management modules for sucking pests of bitter gourd (Momordica charantia L.)

Abstract

An experiment was conducted during kharif 2019 for evaluation of different pest management modules for sucking pests of bitter gourd (Momordica charantia L.) during the course of study, three pest management modules viz., Bio-intensive, Chemical and IPM module consisting spraying of different biopesticides as well as pesticides were evaluated with untreated control in Randomized Block Design (RBD) with five replications. The studies on evaluation of different pest management modules for sucking pests of bitter gourd revealed that for control of thrips, whitefly, aphids and jassids IPM module observed 4.15 thrips, 4.02 whitefly, 4.03 aphids and 4.08 jassids/3 leaves/plant, respectively.Effect of different strategies on predatory coccinellids showed that the Bio-intensive module recorded the highest grub population per plant (4.22 grubs/plant) followed by IPM module which record 3.44 grubs/plant indicating their less toxic effects on to the coccinellids after the sprays taken in these respective modules. The highest yield of bitter gourd fruits 230q/ha was registered from the IPM module with highest ICBR 1:7.25 as against 170 q/ha in untreated control.
