Abstract/ Executive Summary:

A survey was conducted at Hathazari, Satkania and Fatikchari upazila in Chittagong district to identify major insect pest and pest management practices used by the brinjal growers. A total of seventy five brinjal growers were selected for interview during November 2006 to February 2007. Twenty five growers were selected from each area and pretested structured questionnaires were used in this survey. Brinjal Shoot and Fruit Borer was identified as the major insect pest in the study area. Ninety-nine percent of growers relied solely on pesticide use to control brinjal pest. Brinjal growers applied insecticides more than 23 times in a season. Six days interval gaps between insecticide application and fruit harvest. Pesticide dealers were the major source of information to farmers on the selection of chemicals and application methods. Very few growers used protective clothing or other safety measures during pesticide application; 45% of the respondent did not take any safety measures. Where as 29% of the growers covered their face and body. 17% covered their body and 17% covered their face at the time of spraying. On an average 61% of the farmers believed that pesticide application are harmful to farm labour, 27% farmers expressed their views that pesticide application pollute the water and air. This study reflects the irrational use of pesticide use in brinjal cultivation that has serious consequences to human health and the environment.

Objectives:

Objective of the study was to identify major insect pest and pest management practices used by the brinjal growers.

Methodology:

A survey was conducted at Hathazari, Satkania and Fatikchari upazila in Chittagong district. A total of seventy five brinjal growers were interviewed during November 2006 to February 2007 of which twenty five brinjal growers were selected from each area. To determine the recent insecticide use pattern, farmers who did not grow Brinjal over the last one year were not selected. Objectives oriented structured questionnaire was used to identify major insect pest problems and pest management practices with Brinjal cultivation.

Achievement/Findings:

The present investigation demonstrates, BSFB is the most common pest insect in Brinjal and the indiscriminate and irrational use of pesticide to protect Brinjal from insect pest in the study area. The existing pattern of pesticide usage, if continued, will result in future loss of efficacy due to development of resistance by Brinjal insect pest to pesticides. On an average 61% of the farmers believed that pesticide application are harmful to farm labour, 27% farmers expressed their views that pesticide application pollute the water and air. This study reflects the irrational use of pesticide use in brinjal cultivation that has serious consequences to human health and the environment.
