Scope

The main technical content: The selection of seven target substances, including phenol, o-cresol, m-cresol, p-cresol, m-cresol, 4-chloro-3,5-dimethylphenol, and p-nitrophenol, is based on the results of studies in relevant literature showing that these substances have higher concentrations and greater toxicity as pesticide adjuvants. Tang Xiangkai et al. investigated and analyzed the content of 62 organic solvents in 110 liquid pesticide formulations and found that the detection rate of the prohibited phenol was 4.5%, with a concentration of 0.05~0.22%. The detection rates of the restricted o-cresol, m-cresol, and p-cresol were 3.6%, 1.8%, and 0.9%, with concentrations of 0.05~0.23%, 0.09~0.16%, and 0.31%, respectively. This indicates that phenolic pesticide adjuvants are widely used in pesticides and there are cases of misuse. Combined with the "List of Prohibited and Restricted Pesticide Adjuvants" (Draft for Comment) drafted by the Pesticide Inspection Station of the Ministry of Agriculture (see Annex 1) and the results of relevant literature research, we selected pesticide adjuvants that are widely used in China and have greater toxicity as the research targets.
