From 1979 to 1980, for two consecutive years, we conducted chemical weeding trials and demonstrations in 15 battalions in Chaicun, Dian Dian, Xia Jin and other communes. We share 13 kinds of various types of herbicides, with a test area of 320 mu, demonstrating and popularizing 600 mu of land. Applied crops are wheat, cotton, corn, soybeans, vegetables and so on. The results of trifluralin best, are described below: Cotton weeding: Jiuzhou Fort and Chaicun brigade 30 acres of cotton fields, in the early bud stage with 48% of trifluralin 2.5 two, watered 100 pounds, directional spray, Grass-killing effect of 93-95.1%, residual effect of more than 4 months. Maize weeding: Dian Dian, Jin Jin and other four pilot sites in the sowing corn before sowing before and after sowing, mu 2-3 leflunomide, watered down 100 kg of soil treatment, grass killing effect
