Abstract: Improving the efficiencies of pesticides is the key to reducing the amount of using chemical pesticides, decreasing pesticide residues of vegetables, and reducing environmental pollution in the process of controlling vegetables of disease and insect pest.This paper analyzes the factors that affect the efficiencies of pesticides from the characteristics of pesticide, sprayer performance ,crown structure, the biological characteristics of leaf surface and ambient condition ,.This paper raises some suggestions for resolving these questions which could provide theoretical guidance for the scientific application of pesticides.
