Judicious use of insecticides for the management of the brinjal shoot and fruit borer.

Abstract

A study on the use of insecticides for the management of brinjal shoot and fruit borer (Leucinodes orbonalis) was undertaken at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur, Bangladesh, during the period from 29 October 1997 to 17 June 1998. Brinjal [aubergine] variety Singhnath was used in the field experiments. A number of treatments consisting mechanical (hand collection of infected shoots/fruits) and chemical (Cymbush 10EC [cypermethrin] and/or Diazinon 60EC) were tested. The benefit cost ratio (BCR) was highest in plots treated with mechanical control + cypermethrin. A similar BCR was achieved in the plots with weekly spraying of cypermethrin. However, the weekly spraying involved applying 8 times more insecticide.
