Screening of some okra varieties against Earias vittella under Allahabad field conditions

Abstract

Screening experiment was conducted at Central Agricultural field, SHUATS, Allahabad, during kharif 2016 to identify the infestation of okra shoot and fruit borer, Earias vittella (Fab.). Eight okra varieties were screened to know their response on the basis of shoot and fruit damage scale. Based on the infestation of the shoot and fruits (number and weight basis) the grading is done as resistant, moderately resistant, moderately susceptible, susceptible sources. Among the eight genotypes, IC-117076 (5.98%, 8.54%, and 7.03%) and HRB-9-2 (6.78%, 7.01% and 5.78%) were moderately resistant to shoot and fruit damage (number and weight basis) and IC-033854 (16.43%, 25.39% and 21.22%) was found moderately susceptible to shoot and fruit damage (number and weight basis). VRO-4 (18.12%, 39.16% and 32.25%), VRO-3 (16.18% 37.76% and 31.09%) and VR0-22 (17.02%, 38.44% and 31.65%) were found moderately susceptible and susceptible to shoot and fruit damage (number and weight basis), respectively. PUSA SAWANI (31.20%, 39.30% and 32.42%) and IC-45831 (30.01%, 36.98% and 30.45%) found susceptible to shoot and fruit damage (number and weight basis).
