  • In order to objectively reflect the effect of plant protection and the contribution rate of pest control on the yield of fruit trees, in 2022, National Agro-Tech Extension and Service Center(NATESC) organized plant protection stations in 7 counties(cities, districts) of Shaanxi and Shanxi provinces to systematically carry out field comparative tests and evaluate the plant protection contribution rate for apple and pear, which are the major fruit trees in the northern China as the research objects. According to the results of the yield measurement data of the multi-point experiment in seven counties(cities, districts) in two provinces, the plant protection contribution rate of apple pests control in the northern China in 2022 was 35.57%, of which the rate in the scientific comprehensive prevention area, the unified control area, and the farmers' self-prevention area was 50.91%, 37.27%, and 30.95%, respectively. The plant protection contribution rate of pear pest control was 44.38%, of which the rate of scientific integrated control area, unified control area, and farmers' self-control area was 56.17%, 42.84%, and 36.09%, respectively. The results showed that the prevention and control of pests contributed greatly to the fruit yield and plant protection contribution rate, and still has great potential.
