In recent years, the research on the prevention and treatment of rice fever has focused on organic mercury preparations. In 1956, 1: 6 Xili lime powder was tested, and its prevention effect was compared with Bordeaux mixture, copper soap solution, And lime sulfur mixture is excellent, spray medicine at the heading stage, can reduce ear fever neck disease 70%. In order to guide the popularization and application of a large area, in 1956, the main organic mercury preparations Xi Li-sheng (containing 2% ethyl mercuric chloride as the effective component, Shanghai Pest and Disease Pharmacy Co., Ltd.) and Saracenic (containing the active ingredient phenylmercuric acetate 2.5% , West Bayer Pharmaceuticals), spray mixed with hydrated lime after the number of mixed this case, endurance, the impact of rain on the efficacy, spraying time, the number of injuries and other issues in Zhenhai and Dongyang further work The test, the results are as follows:
