1. According to the information of China Pesticide Network, Mr. Tang's two zeros refer to two pesticides, namely 0.3% thiophanate-methyl EC and 0.3% propionyl methyl sodium thiosulfate suspension. Firstly, a certain amount of 0.3% thiophanate-methyl EC and 0.3% propionyl methyl sodium thiosulfate suspension were evenly stirred to generate a mixed solution.

2. Add the mixed solution into water according to a certain proportion to make liquid medicine.

3. Spray the liquid medicine solution evenly on the vines to ensure that the liquid medicine fully covers and penetrates into all parts of the vines. And pay attention to the preparation of liquid medicine in strict accordance with the proportion, to avoid using too many pesticides to cause damage to fruit trees.
