Description

technical field

[0001] The invention relates to the field of cotton insecticides, in particular to a cotton insecticidal composition containing nitenpyram and a preparation method thereof. Background technique

[0002] Cotton is one of the important economic crops in our country. Cotton diseases and insect pests have various occurrences and frequent outbreaks, which are important factors that threaten the safety of cotton production in my country. There are many types of diseases and insect pests in cotton cultivation, and their prevention and control is a difficult problem. Cotton is severely damaged by insects at the seedling stage. Different damage time and damage methods have a great impact on the growth of cotton seedlings, and also bring certain difficulties to field control. Some of the pests spread viruses, some affect the length of cotton and delay the development, and some lose their growth points and become male cotton, or the stems are broken to cause headless t...
