It is used to protect wet-sown rice from triachlor, and is generally used in a mixture of 100-200g (a.i.)/ha and triachlor (ratio 1:3) under sub-tropical and sub-tropical conditions, and in the temperate zone the ratio is 1:2. It had no effect on the growth rate of rice leaves. When proachlor was applied to the roots and branches, the effect of weeding was delayed, and it was also effective when applied to rice before herbicide application. Field experiments showed that the herbicide application was effective two days after the absorption of safety agent, but the application of propachlor for 1 to 4 days would greatly affect the recovery of crops.And butachlor ratio is about 1:8.Package
