THE EFFECT OF VARIETY AND INSECTICIDE AGAINST BEAN POD BORER (MARUCA VITRATA) ONSUMMER COUNTRY BEAN

Abstract

The experiment was conducted to evaluate the performance of different varieties and management practices in controlling bean pod borerof country bean during the period from April to October, 2014. The experiment consists of the bean varieties as the IPSA Seem-1, IPSA Seem-2, BARI Seem 7, and insecticides Voliam Flexi 300 SC, Sumi Alfa 5 EC,Neem seed karnel as the treatments. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The minimum infestation percentage (11.71 %) and maximum yield (17.61 t/ha) was obtained from BARI Seem 7 while variety and the maximum infestation (14.86 %) and minimum yield (12.90 t/ha) was obtained from IPSA Seem-1 variety. The minimum infestation (12.24 %) and maximum yield (15.77 t/ha) was obtained while sprayed Voliam Flexi 300 SC treatment and the maximum infestation (14.56 %) and minimum yield (14.42 t/ha) was obtained from the control treatment. In case of combined effect the minimum infestation (9.52 %) and maximum yield (19.20 t/ha) was obtained from combination of BARI Seem 7 and Voliam Flexi 300 SCand the maximum infestation (22.02 %) and minimum yield (10.70 t/ha) was obtained from IPSA Seem-1 and control treatment combination. The relationship between percent pod infestation by number and yield (t/ha) is negatively corelated. From the study it may be concluded that BARI Seem 7 treated with Voliam Flexi 300 SC performed the best results
