| Abstract: | According to the injury of the cotton, mode of action, efficacy of the adjacent weed and the situation of the manufactures, 20 herbicides were determined to detect which could injure the cotton. The HPLC-DAD was applied, the retention times and the ultraviolet spectrograms of the 20 herbicides and the sample which injured the cotton were detected and compared at the same detecting condition. There was 4.7% tribenuron-methyl in the formulation of imidacloprid 2.5% WP which caused the injury on cotton. |
