Abstract
Abstract: The present investigation entitled “Effect of insecticides and bio-pesticides on groundnut pod damage in field and storage” was undertaken to find out the effect of soil drenching of different insecticides on groundnut pod damage in field and pod damage (Caryedon serratus) in stored groundnut. The experiment was conducted in the Research Field of Oilseeds Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the year 2020-21. Insecticides and bio-pesticides viz. Metarhizium anisopliae (1x 108 CFU/mg), Beauveria bassiana (1x 108 CFU/mg), carbofuran 3 CG, chlorpyriphos 20 EC, deltamethrin 2.8 EC, lambda cyhalothrin 5 EC were soil drenched in field. At harvest examined the damage of pod borers in field and freshly harvested pods filled in storage bags and stored in godown for six months for examining the damage due to Caryedon serratus.
Soil drenching with carbofuron 3 CG @ 33.3 kg/ha recorded the groundnut pod damage due to soil pod borers below 3 per cent i. e. 1.63 per cent at harvest followed by chloropyriphos 20 EC @ 2ml/l (2.78 % pod damage). Soil drenching with insecticides applied in field found effective upto three months of storage. Treatment lambda cyhalothrin 5 EC @ 0.6ml/l kept the groundnut pod damage due to Caryedon serratus upto 33.5 per cent after six months of storage followed by deltamethrin 2.8 EC @1.25ml/l (37.05 % pod damage). Kernel damage due to bruchids from the treatment lambda cyhalothrin 5 EC @ 0.6ml/l was recorded below 10 per cent i.e. 7.29 per cent after three month of storage followed by deltamethrin 2.8 EC @ 1.25ml/l recorded 9.20 % kernel damage.
Treatment lambda cyhalothrin 5 EC @ 0.6ml/l kept the number of live adult emergence of Caryedon serratus below 10 i.e. 2.67 up to four months of storage period followed by deltamethrin 2.8 EC @ 1.25ml/l recorded 4.00 live adults. Lambda cyhalohrin 5 EC @ 0.6ml/l kept egg laying of bruchid upto 50.33 eggs after six months of storage.
Loss in weight treatment lambda cyhalothrin 5 EC @ 0.6ml/l was recorded 20.83 per cent weight loss in pods and 26.51 per cent weight loss in kernel.
Description
Description: The experiment was carried out on the Research Field of Oilseeds Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, during 2020-21 to study the effect of insecticides and bio-pesticides on groundnut pod damage in field and to study the effect of insecticides and bio-pesticides applied in field on groundnut pod damage, Caryedon serratus in storage. Treatment comprised of insecticide Metarizium anisopliae, Beauveria bassiana, carbofuran, chloropyriphos, deltamethrin, lambda cyhalothrin, control which were executed in Randomized block design with three replications.
