Abstract
A survey study was conducted among two hundred farmers from Patuakhali and Comilla district, Bangladesh to determine the farmers’ awareness about farm land pesticide application on major crops with beneficial and harmful effects, pesticide use trends in last five years (2011−2016), crop harvesting time after pesticide application, integrated pest management (IPM) with indigenous technology etc. determinants. Survey result showed that 82% of the farmers of Patuakhali cultivating local varieties of rice and used IPM with indigenous technology in addition with application of pesticides for pest management. Though these farmers did not use any pesticide in 2011 except carbofuran but in 2016, they are used various kinds of organocarbamate and organophosphate pesticides for controlling pest. On the other hand, farmers from Comilla regions increased their pesticide application three times during the last five years and used only piercing as an indigenous method for pest management. Pesticide application intensity (3/4/more times in a cropping season) higher in Comilla region compared to that of Patuakhali region. Vegetables harvesting time within 24 or 48 hrs after application of pesticides will be alarming for consumers due to toxicity development of pesticide residue. Application of pesticides more than the recommendation limits increasing the environmental, animal and human health risk at the studied area. It is concluded that effective implementation of government policy, continuous monitoring, increasing IPM practices, expansion of indigenous technologies and as a whole growing farmers’ awareness about the pesticide use are suggested for sustainable and quality crop production and healthy consumption.
Highlights
Agricultural is one of the important economic sectors in Bangladesh to nearly half of the country economic output
A questionnaire was prepared for collecting data by using face to face interview system about major crop cultivation, experiences about crop production, major diseases and pest infestation with their management practices, pesticide application intensity and doses, crop harvesting time after last pesticide application, pesticide use trends in last five years (2011 and 2016), farmer’s perception for pesticide application with their associated human and environmental health risk etc. determinants
A number of diseases and pests occurred by various pathogen causes significant crop losses in Bangladesh and estimates of the scale of these losses vary by context and scope
Summary
Agricultural is one of the important economic sectors in Bangladesh to nearly half of the country economic output. This sector facing many challenges due to severe agroclimatic conditions like annual flooding, cyclones, tidal storms and salinity etc. As a direct consequence of these difficult conditions, agricultural production has been highly susceptible to attack pests and diseases. In their defense, farmers have begun to use more pesticides to prevent crop losses from pest attack. Pesticide use in Bangladesh negligible until the 1960, has recorded a dramatic increase over the past five decades This is partly due to government’s preference to adopt chemical control measure to increase
