Recently, strong convection weather such as short-term heavy rainfall and short-term strong wind occurred in many places in Hebei Province. At present, it is the critical time of the middle-late period of cotton management, and the environment of cotton field with high temperature and high humidity after rain is easy to cause the outbreak of diseases and pests.

In view of the high field humidity after rain, which is easy to lead to cotton rot disease, experts put forward that the ditch should be cleared in time to reduce soil moisture and improve field microclimate. Fungicides such as thiophanate-methyl and pyraclostrobin should be sprayed on leaf surface to prevent the occurrence and spread of diseases. In view of the recent serious occurrence of insect pests such as mirid and beet armyworm in some cotton areas, insecticides such as sulfoxaflor and chlorantraniliprole should be sprayed in time according to the actual situation in the field to control the harm of insect pests. For the contiguous cotton field, insecticides should be used from the periphery to prevent the spread of pests.
