Abstract:
Pest management under organic farming is a challenging task, wherein, ecofriendly approaches against insect pest were accomplished through the use of appropriate strategies which promotes manipulation and alteration of agro-ecosystem. In this view, an experiment was laid out in Randomized Block Design with SSV-74, a sweet sorghum cum fodder variety (during kharif 2021-22 and 2022-23) at certified organic block (certified since 2006), Bio-Resource Farm, Institute of Organic Farming, University of Agricultural Sciences, Dharwad. The analysis of pooled data for two seasons revealed that, among various plant products evaluated the plots treated with NSKE @ 5% found superior with significantly lower incidence of shoot fly (1.44 eggs /plant and 8.92% dead hearts), and stem borer larvae (3.47 larvae /m row) as well as fall armyworm (1.20 larvae/plant) with considerably least damage severity. This was followed Vitex negundo @ 5%. However, all the organic plots documented relatively higher population of beneficial fauna in comparison with inorganic check.
