Abstract

Integrated pest management (IPM) is an environmentally friendly technology. IPM is a multifaceted approach to pest management that seeks to minimize negative impacts on the environment. This technique is an important step towards providing healthy, viable food for a growing global population. The focus of this study was to examine the impact of integrated pest management in a rice agroecosystem. Currently, more than 80% of farmers rely on pesticides. IPM methods employed in our study had an impact on the number of healthy tillers and hills and grain weight. The lowest percentage of dead heart (1.03) and white head (2.00) was found in the IPM treated plots. These plots had an average yield of 7.4 tonne/ha. We found that there were significant differences between the treatment and the observed percentage of dead heart, grain weight, and yield. We conclude that IPM practices are an effective strategy for obtaining high rice yields while protecting the environment and creating a more sustainable agroecosystem. Furthermore, the need for ongoing research and training on IPM methods will be essential for creating a sustainable rice agroecosystem.

Highlights

Rice is a staple food for more than fifty percent of the world’s population [1]
In conventional pest management strategies the role of predator species is minimized or even eliminated by heavy pesticide application (Table 3)
We found the incidence of dead heart and white heart both to be relatively lower in the Integrated pest management (IPM) treated plots; the percentage of white head and dead heart both was observed to be lower than established critical limits [35]

Summary

Introduction

Rice is a staple food for more than fifty percent of the world’s population [1]. For decades rice crops have directly or indirectly played a key role in the livelihood of several billion people. In 2010, 154 million hectares of rice were cultivated worldwide, of which 137 million hectares were in Asia, with 48 million hectares harvested in Southeast Asia [2]. In Bangladesh, eighty percent of agricultural land is dedicated to rice cultivation [3]. Of the rice growing regions in Bangladesh, Barisal is one of the most important, due in part to the diversity of rice under cultivation. For this reason, as well as the region’s consistently high yields, Barisal is known as the “Crop House of Bangladesh,” for several decades farmers have been plagued by a number of pest related issues [3]
