Scope

Scope: This standard specifies the prevention and control principles of green prevention and control of rice diseases, pests, and weeds; field monitoring of diseases and pests; agricultural prevention and control; major disease prevention and control techniques; major pest prevention and control techniques; weed prevention; and scientific and standardized pesticide application. This standard applies to the green prevention and control of diseases, pests, and weeds. Main technical content: 5. Field monitoring of diseases and pests: Conduct rice field disease and pest monitoring according to GB/T 15790, GB/T 15791, DB23/T 1594-2015, and DB23/T 1414-2011. Implement dynamic monitoring of other diseases and pests to timely grasp their occurrence. 6. Main disease prevention and control techniques: 6.1 Seed treatment: Use 1% lime water, or fungicides such as Cyazofamid and Methiocarb to soak seeds to prevent rice seedling blight. Follow the instructions of the fungicide to operate. 6.2 Seedbed management: Apply seedling growth enhancers with functions of acid adjustment, fertilization, and disinfection according to the instructions. Disinfect the seedbed soil with fungicides such as Oxathion or Metalaxyl-M. Scientifically manage the temperature and humidity of the rice seedbed and ventilate it in time to improve the seedling quality. 6.3 Control of seedling blight: When the seedlings are at the 1.5-leaf stage, spray biological pesticides such as Paecilomyces lilacinus, Metarhizium anisopliae A, or chemical pesticides such as Metalaxyl-M, Oxathion, and Cyazofamid on the seedbed. 6.4 Control of rice blast: When the field-level disease severity of rice blast reaches grade 2 (standing on the pond bank, able to see sporadic disease spots on the leaves), implement pesticide prevention. For spike-neck blast, spray pesticides at two critical periods: the late stage of rice panicle initiation and the full panicle stage. Biological pesticides can be selected such as Bacillu
