Socio-economic Study of Insecticide Use on Vegetable Cultivation at Farm Level in Chittagong Region

Mr. Md. Mohiuddin
PhD Fellow
ARS Bangladesh Agricultural Research Institute Kishoregan Bangladesh

Abstract/ Executive Summary:

The study was conducted in Satkania, Patiya and Hathazari upazilas of Chittagong district during 2008 to identify different pest problems and practices, input use and economic returns at farmers’ levels. About 95% of the farmers relied on the application of insecticides to control insect pests and they said that the insecticides use was profitable. Majority of the farmers of Patiya sprayed insecticides more than 40 times in brinjal cultivation. For other selected vegetables, farmer’s sprayed insecticide more than 15 times in a season. Especially for Satkania, majority of the farmers sprayed every alternative day while in the winter, the spraying frequency was reduced once a week. Pesticide dealers were the major source of information to farmers on the selection of chemicals and application methods. Very few farmers used protective measures or safety measures during pesticide application, only 39% of the respondents did not use any safety measures where 21% of the vegetable growers covered their body and faces. Eight percent covered their face and 32% covered their body at the time of spraying. On an average 61% believed that pesticide application are harmful to farm labour, 40% farmers expressed their views that pesticide application pollute water and air.

Keywords: Insecticide use, Vegetable cultivation, Socio-economic characteristics

Location: Hathazari, Patiya and Satkania upazilas of Chittagong district

Start Date: 01-07-2008

End Date: 30-06-2009

Program Area: Socio-economic and Policy

Commodity: Amaranth

Objectives:

i) to know the socioeconomic characteristics of insecticide users

ii) to know the application of insecticides for vegetables

iii) to observe the impact and implication of using insecticides.

Methodology:

Data were collected from Hathazari, Patiya and Satkania upazilas of Chittagong district during the month of May, 2008. Because of intensive vegetable cultivation in those upazilas a total of 120 farmers were selected purposively taking 40 from each crop and from each study area. On the basis of high insecticide use, three vegetables namely brinjal, country bean and yard long bean were selected based on the intensive cultivated area. Brinjal shoot and fruit borer for brinjal, aphid, bean borer and white fly for country bean and pod borer for long yard bean were the key insect pests in the study areas. Predesigned and pre tested interview schedules were used for data collection. The collected data were coded, edited for processing through tabular method using average, percentage, ratio etc.

Achievement/Findings:

Vegetable cultivation is highly profitable on the basis of its returns to investment. The present study clearly demonstrated the indiscriminate, irrational and whimsical use of insecticides in selected vegetables. The existing excessive use of insecticides are causing different consequences like development of resistance power of pest, the killing of natural enemies which may again lead to the favourable condition for the development of pest population. This again results the disruption of agro-ecosystem, environmental pollution and serious threat to human health. Majorities of the farmers did not use biological and cultural methods. Very few farmers use simple sanitation method. Information dissemination through mass media should be undertaken on the successful and proper dose of insecticide use as well as the detrimental effect of insecticides use in vegetable cultivation.
