Abstract: Rice is one of the major grain crops in China. It is the key measure for prevention and controlling rice diseases and pests to ensure the rice yield and increase farmers' income, reduce the yield losses and increase production efficiency. National Agricultural Technology Extension and Service Center (NATESC) organized the evaluation of the contribution rate of plant protection for rice crop in six provinces (autonomous region), including Heilongjiang, Jiangsu, Jiangxi, Hunan, Guangxi and Sichuan. The contribution rate of plant protection for controlling the insect pests and diseases of the rice crop was 19.46% assessed by the method of multi-point test with four treatments, strict prevention and control area, unified control area, farmers' self-prevention area, and non-control area in 2022. According to the assessment, plant protection retrieved a loss of 4,141.90 million tons of rice. The results of statistical analysis show that the rates of strict prevention and control area treatment, unified control area treatment were 8.97% and 4.35% higher than that of farmers' self-prevention area treatment, respectively.
