Abstract

The main purpose of this study was to find out the best variety of brinjal having resistance to BSFB. A pot experiment was carried out at the germplasm centre, Agrotechnology Discipline, Khulna University, Khulna during February 2014 to August 2014. The experiment was laid out in CRD using thirteen varieties with five replications. The varieties were V1=BARI begun-1, V2=BARI begun-4, V3=BARI begun-5, V4=BARI begun-6, V5=BARI begun-7, V6=BARI begun-8, V7=BARI begun-9, V8=BARI begun-10, V9=Makra, V10=Muktokashi, V11=Lalita, V12=Hazra, V13=Chaga. Data were collected on total number of shoot, total number of infested shoot, percentage of shoot damage, percentage of shoot infestation reduction, numbers of larvae per infested shoot, total number of fruit, percentage of fruit damage, percentage of fruit infestation reduction, numbers of larvae per infested fruit. Results have shown that the minimum shoot infestation was found in BARI begun-6 (29.60%, 32.40%, 29.86% and 29.38%, respectively at four different stages of eggplant). Percent of fruit infestation was minimum in V4 (BARI begun-6) (25.16%, 27.42% and 25.40% at three stages respectively).J. Bangladesh Agril. Univ. 16(2): 227-231, August 2018

Summary

Introduction

Brinjal (Solanum melongena L.) is one of the important vegetables in South and South-East Asia (Thapa, 2010) cultivation of which helps to improve human nutrition and generate income. It is cultivated more than 1.6 million ha of land producing about 50 million MT throughout the globe (FAO, 2012). Farmers of Bangladesh in most cases solely depend on insecticides for the management of this pest Such dependence on insecticides has created many problems such as excessive residues on marketed vegetables that concerns general consumer’s health and the environment, pesticide resistance, trade implications, poisoning, hazards to non-target organisms, increased production costs etc. Such dependence on insecticides has created many problems such as excessive residues on marketed vegetables that concerns general consumer’s health and the environment, pesticide resistance, trade implications, poisoning, hazards to non-target organisms, increased production costs etc. (Alam et al, 2003; Pedigo, 2002)
