Since 2004, the Ministry of Agriculture has organized and implemented the "Metopamine Phosphorous and other Highly Toxic Pesticide Substitution Test Demonstration Research Projects". Through the comprehensive evaluation of indoor bioassay screening and Daejeon efficacy demonstration, the search for highly toxic pesticides is prohibited. After the replacement of pesticides and related technologies. In 2006, alternative pesticide products for the four major crops of wheat, vegetables, rice, and cotton were announced. At the same time, in conjunction with the actual situation of agricultural production in our province, the plant protection experts in our province have recommended related pesticides.

l. Prevention and control of rice borer borer, spray application in the incubation period of the eggs of the rice borer, and the available varieties are: (1) Triazophos, and the recommended dose is 30 to 40 grams of active ingredient per acre.
