Last year, we used different concentrations of two hundred twenty-three to control the small tigers at the seedling stage of cotton. Through field and indoor repeated multi-point experiments, the results showed that using 800 times 233 to control the cotton seedling stage tiger, the effect is ideal. Now the test conditions are briefly described as follows: First, the test method Field trials: in the Bayi Brigade sixth production team and Jiangdong Brigade second farming team wheat fields were set at 200,400,600,800,1000,1500,2000 times And blank control eight plots for testing, the amount of liquid per acre, Bayi Brigade six teams of 180 pounds, Jiangdong second farming
