Estimation of pesticide residues in rice grains in Western Uttar Pradesh

Abstract

The primary role of agriculture is to produce a reliable supply of wholesome food to feed the burgeoning world population safely and without adverse effects on environment. Total paddy acreages in Uttar Pradesh are estimated at 1,614.1 thousand hectares in 2019 which are 21% higher than the last year acreages of 1,336.1 thousand hectares. Basmati acreages in 2019 are estimated at 463.6 thousand hectares which is 84% higher than the last year acreage of 252.1 thousand hectares. Out of total Basmati acreages PB 1509 has the largest share of 44%, followed by PB 1121 (35%) and PB-1 (10%). Of the total non-basmati acreages, non-notified varieties (Sharbati and Sugandha) have been transplanted in 376 thousand hectares in Uttar Pradesh. Intensive pesticide has increased grain production, its use has several drawbacks. In addition to the direct costs of the pesticides, long-term and highly concentrated application of pesticides may contaminate the products of field crops, as well as pose a serious danger to the agro-ecosystem (e.g., the surrounding soil and water quality) and human health. This study is done to assess the pesticide residues in rice grains in the major rice growing areas of Western Uttar Pradesh using QuEChERS method. In the present study 19 pesticide residues were found in 23 samples of rice which was compared and evaluated with MRL value as per EU. The data generated from this study can be used as a reference point for future scrutiny as well as for providing basis for developing sustainable natural resource management practices and for taking preventive measures to reduce human health risks.
