Abstract

An experiment was conducted during kharif season of 2018 and 2019 to know the infestation of okra shoot and fruit borer, Earias vittella (Fab.). Thirty germplasm/varieties were taken to know their response against shoot and fruit borer. On the basis of shoot damage scale, none of the germplasm/varieties was found immune or resistant. Five germplasm were moderately resistant while twenty-one and four germplasm fell under moderately susceptible and susceptible categories respectively in 2018. During 2019 and pooled data follow same pattern of 2018, On the basis of fruit damage scale germplasms/varieties were evaluated on the basis of fruit damage none of them came under immune or resistant categories. One, twenty-one and eight germplasm found moderately resistant, moderately susceptible and susceptible respectively during 2018. While during 2019 none of them came under immune or resistant categories One, nineteen and ten germplasm found moderately resistant, moderately susceptible and susceptible respectively and in pooled data was followed same pattern of 2019.
