Seasonal incidence and bioefficacy of insecticides against leaf miner Chromatomyia horticola (Goureau) infesting pea

Abstract

The present investigations entitled bioefficacy of insecticides against leaf miner, ( Chromatomyia horticola Goureau) (Agromyzidae: Diptera) infesting pea ( Pisum sativum L.) was carried out at experimental farm of Agricultural Entomology Section, College of Agriculture, Pune under Mahatma Phule Krishi Vidyapeeth, Rahuri during Rabi-2020-2021. The pooled data on bioefficacy of insecticides used against leaf miner on pea revealed that the spinetoram 11.7% EC was found most superior and significantly effective with minimum infestation (9.78%) over the rest of the treatments. The treatments of chlorantraniliprole 18.5% SC (10.71%) and emamectin benzoate 5% SG (11.35%) was statistically at par with each other in managing the pest of leaf miner on pea while the remaining treatments like azadirachtin 10000 ppm (12.42%), deltamethrin 2.8% EC (13.12%), cartap hydrochloride 50% SP (14.34%), lambda cyhalothrin 5% EC (16.37%) and profenphos 50% EC (18.72%) were also found to effective for controlling of horticola on pea.
