Pesticides are widely used to protect crops from pests, diseases, and weeds, but their effectiveness can vary depending on various factors such as the type of pesticide used, the timing of application, and environmental conditions. To assess the efficacy of pesticides, several methods can be used. During the development stage of pesticides, laboratory tests are conducted to assess the effectiveness of insecticides under controlled conditions. Bioassays can be used to determine the toxicity of the pesticide to specific pests, pathogens, or weeds. Laboratory testing can provide precise data on the efficacy of the pesticide, but it may not accurately represent real-world conditions. Therefore, another approach is to conduct field trials where a pesticide is applied to a crop and its effectiveness is measured by comparing the degree of pest and disease occurrence between pesticide-treated plots and an untreated control plot. In addition, the yield and quality of pesticide-treated crops can be monitored. In Japan, the details and procedures of field tests related to the effectiveness of pesticides are conducted in accordance with the "Agricultural Chemicals Regulation Act", "Regulations for Enforcement of the Agricultural Chemicals Regulation Act", and "Data Requirements for Registration of Agricultural Chemicals" issued by the Ministry of Agriculture, Forestry and Fisheries (MAFF). Submitted data for registration of an agricultural chemical are evaluated by the Food and Agricultural Materials Inspection Center (FAMIC) under the guidelines mentioned above.
