Abstract:
The studies on Management of lesser grain borer Rhyzopertha dominica (Fabricius) associated with stored cereals were carried out to know the impact of phyto extracts and bio rationals on the mortality of the pest and germination response of treated seeds. The research was carried out at Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, U.P. in Department of Entomology 2022-2023. This experiment was conducted under Complete Randomized block Design (CRD). The experiment was conducted on effect of phyto extracts and bio rationals on the mortality of adult Rhyzopertha dominca (Fabricius) at 3,7 and 10 days of exposure. In Rice, results proved that 100 percent mortality was observed after 10 days of exposure to spinosad 45SC followed by Emamectin benzoate, sweet flag rhizome powder, cinnamon bark oil, mentha leaf oil, clove bud oil and eucalyptus oil. In wheat, 100 percent mortality was observed after 10 days exposure to spinosad 45SC followed by sweet flag rhizome powder, emamectin benzoate, cinnamon bark oil, mentha leaf oil, clove bud oil and eucalyptus oil. In maize, 100 percent mortality was observed after 10 days exposure to Spinosad 45SC followed by emamectin benzoate, mentha leaf oil, sweet flag rhizome powder, clove bud oil, cinnamon bark oil and eucalyptus oil. Experiments conducted on germination of treated seeds have resulted in no adverse effects on germination percent. The germination of treated grains with spinosad 45SC in most effective followed by emamectin benzoate, sweet flag rhizome powder, clove bud oil, mentha leaf oil, cinnamon bark oil and eucalyptus oil. Therefore, present laboratory studies clearly showed that phyto extracts and bio rationals were found quite effective against Rhyzopertha dominica (Fabricius) without causing any deleterious effect. Hence, it may be concluded that these eco-friendly and cost-effective products can easily be made available and used for management of Rhyzopertha dominica in stored cereals without impairing the quality of seeds for 3 months of storage period.
