Abstract:

As the primary staple crop in China，the pesticide residue status of paddy rice directly affects national health and food security，and influences the high-quality development of the rice industry. On March 1，2026，GB 2763-2026 National food safety standard-Maximum residue limits for pesticides in food was officially implemented，fully replacing GB 2763-2021 and GB 2763.1-2022. As a core cereal category，paddy rice has undergone systematic adjustments in its pesticide residue limits，regulatory scope，and testing methods. Based on the text of GB 2763-2026，this paper systematically reviews the specific residue limits for insecticides in paddy rice and compares them with insecticides registered for use on rice in China. The results show that among the 75 insecticide active ingredients registered for use on rice，45 have established maximum residue limit（MRL）for paddy rice，and 5 are exempted from the need for MRL，yielding a coverage rate of 66.7%. Among the 92 MRLs of insecticides for paddy rice，only 45 correspond to insecticides registered for use on rice，giving a match rate of 48.9%. This paper analyzes the matching degree of MRL coverage and the distribution of registered product quantities，aiming to provide technical references for rice growers，testing institutions，and regulatory authorities in implementing the new national standard and ensuring the quality and safety of paddy rice.
