Abstract

An experiment was conducted during kharif of 2007 and 2008 to know the infestation of shoot and fruit borer, Earias vittella (Fab.) on okra. One hundred germplasms / varieties were taken to know their response against okra shoot and fruit borer, on the basis of shoot  damage scale. Only two germplasm showed resistance, fifteen moderately resistance, 66 moderately susceptible  and 17 susceptible in 2007, while during 2008 only single germplasms found resistance whereas 16 moderately resistance and  rest follow same pattern. The pooled data followed similar pattern of 2007. The minimum shoot damage observed  in germplasm 315  whereas  maximum  shoot  damage observed  in Thin No. 3. On the basis of fruit  damage scale 16 germplasms were found moderately resistance, 24 moderately susceptible  and 60 susceptible during  2007 , while during 2008 ,16 were found moderately resistance,21 moderately susceptible  and 63 susceptible. The pooled data showed that 16 germplasms were moderately resistance, 22 moderately susceptible and 62 susceptible. Minimum fruit damage was observed  in germplasm 472  whereas  maximum  observed  in Thin No. 3.
