Effect of Some Soil Insecticides in Controlling the Major Insect Pests in Teak Nursery

Abstract

Suitable control measures were devised for tackling the white root grubs in teak nursery at Katanga (Balaghat, M.P.) and noticed that Basuddin (Diazinon) lOG @ 200g/bed (10m X 1m) followed by Phorate (Thimet lOG) 200g/bed was very effective against the white root grub, H.serrata. In case of various doses of Phorate (Thimet) 10G, 200g/bed followed by 150g/bed was best among the other doses. In treated plots of BHC, Furadon and Sevin, the cumulative effect of larval population of teak defoliator, H.puera and skeletonizer, E.machaeralis, the observations confirm that Sevin 50 W.P. @ 200g followed by BHC 50 W.P. @ 600g/ bed was most effective against these pests.
