ABSTRACT

The study was conducted from November 2018 to May 2019 to investigate various aspects of pesticides use in ladies finger cultivation at coastal Rampal Upazila Bagerhat district. In the research, data were collected through preparatory and pre-tested questionnaires related to the characteristics of ladies finger growers, frequency of pesticide use and its environmental aspects. A total of 150 farmers were randomly selected for the critical analysis of pesticides used in ladies finger cultivation. Ten FGDs were conducted on the survey site. During the interview, it was discovered that participants had been cultivating ladies finger since 19.8 years and had almost 30 decimals land. The survey also showed that farmers’ monthly incomes were almost 30,000 Tk. The study comprehensively stated that the growers used five different types of pesticides, where more frequently used Cypermethrin (79%) over a period of 7 to 10 days interval. They maintained a mid-term safe period (9-12 days) prior to the ladies finger harvest after application of insecticides. The bad sign is the use of higher doses, which must be minimized immediately, and consultation with the Agricultural Extension Department (DAE) is most welcome. After using insecticides, they safely discarded empty packages and bottles, which were usually buried underground. While spraying, they followed different types of health/safety principles/regulations, of these the most commonly followed were spraying accordingly wind direction and paid little attention to eating. Although pesticides increased the ladies finger yield, farmers showed their dissatisfaction with expensive and ineffective action. So they often demand cheap prices and effective pesticides for vegetables.

Key words: pesticides, sustainable environment, ladies finger, Rampala upazila.

Introduction

Pesticides are used to better protect the field crops from estimated damage caused by insects and pests. Despite all the advanced techniques used to grow crops, pest control cannot be ignored. Oerke et al. (1995) reported several hundred success stories in which chemical pesticides provided complete plant protection and increased yield drastically. Pesticides and related agricultural chemicals have thus become an integral part of sustainable agriculture mostly in developing countries. Occasionally, several pests attack completely and damage standing crops. This enormous loss can be overcome by adopting appropriate practices for quality pesticides and pest control on the farmer’s field. Commercial farmers are currently completely dependent on the use of pesticides for insect control. Now days it is assumed that the irrational use of pesticides and harvesting vegetables after 1-2 days of pesticides used, is the normal practice (Kabir et al., 1996). On the other hand, the widespread use of pesticides has caused the environmental contamination, namely soil, air, water and food; even under well-managed conditions, application of spray materials remain into soil, water, and other biotic materials is likely to cause residue deposition. Over the past three decades, the selective use of chemical pesticides in agriculture has caused serious health and environmental problems in developing countries like Bangladesh (World Resources, 1999). Gani (1997) reported that the use of pesticides also kills beneficial creatures and insects and renders the soil infertile. In addition, the indiscriminate use of pesticides creates insect resistance, which in turn poses an increased threat to the crop. Sattar (1983) reported that pesticides after application directly or indirectly come into contact with plants, livestock, wildlife, aquatic and terrestrial life, the terrestrial environment and pose minor or serious risks to biodiversity. Increased use of pesticides in agriculture has thus led to the presence of residues in
