Evaluation of different cultivars against shoot and fruit borer Earias vittella (Fab.) in okra

Abstract

The present field experiment was conducted during Kharif season- 2014 at Research Farm, Department of Entomology, JNKVV, College of Agriculture, Rewa (M.P.) to evaluate the cultivars of okra against shoot and fruit borer, Earias vittella (Fab.) under the agro climatic condition of Rewa district. Ten cultivars were evaluated for assessing the infestation of okra shoot and fruit borer on percentage of damaged fruits on number and weight basis. The mean percentage of damaged fruits on number and weight basis in different cultivars were varied from 9.01 to 22.16% and 8.34 to 21.59% as compared to check variety; Julie (15.89% and 15.44%). The lowest percentage of damaged fruits (9.01%) as well as the minimum percentage of weight loss (8.34%) was observed in cultivar; Purvi which gave the maximum healthy fruits yield of 2196g./ ten plants (i.e. 81.33 q./ha). The highest percentage of damaged fruits i.e. 22.16% and maximum percentage of weight loss of 21.59% was recorded in cultivar Bhindi selection-51 which gave the minimum healthy fruit yield of 1242g./ ten plants i.e. 46 q./ha. The minimum percentage of damaged fruits and weight loss (i.e. 9.01% and 8.34%) was recorded from cultivar Purvi which was at par with Super Rekha (9.31% and 8.40%) and were found significantly superior over other cultivars including variety; Julie (15.89% and 15.44%).The highest percentage of damaged fruits and weight loss (i.e.22.16% and 21.59%) was recorded from cultivar Bhindi selection-51 followed by Abhimanyu (20.19% and 19.60%) and Bhindi No.-319 (19.06% and 18.62%) which were significantly inferior to check variety.
