Technique System of IPM (Integration Pest Management) in Xinjiang Cotton Area

Based on the ideas and principles of agroecosystem in Xinjiang cotton crop region and the purpose of controlling pest and improving cotton product and quality, cotton disease and insect pest integrated control technique system in Xinjiang is constructed. In this system, by means of strengthening, protecting and utilizing natural enemies, bringing natural control into full play, taking agricultural measures such as autumn plougging and winter irrigation, the proper arrangement and rotation of cotton and other crops and proper cultural practice brought down the major cotton diseases and insect pest population below economic injure level. By means of selecting insecticides scientific and rational, inclining the number of insecticides and fungicides, reduced the environment pollution to field ecology. Economic, social, ecological benefits have gained obviously after setting this technique system.
