Background and overview[1][2]
The chemical name of chlorphosphonate is: O-ethyl-O-(5-methyl-2-nitrophenyl)-N-sec-butylaminophosphorothioate, also known as phosphorus, butyl Aminophosphorus antioxidant manufacturer, English name: Phosphoramidothioicacid, N-(1- methylpropyl)-, O- ethyl- O- (5-meth original hot melt adhesive imported from Germany yl-2- nitrophenyl, inhibits the movement of phosphorus in the soil It has very little resistance and mainly damages the meristem tissue of plants. Therefore, the position and structure of the meristematic tissue of crops and weeds, soil structure, and the application method of pyrostatin have a great impact on the selectivity of the drug. Generally, upland crops such as carrots , cotton, wheat, beans, potatoes, upland rice, etc. can be treated with 1 to 2.4kg ai/hm2 of glufosinate ai/hm2 as post-sowing and pre-emergence soil treatment. However, pre-emergence treatment of lettuce, cabbage, onions, etc. has phytotoxicity. It can be used before transplanting For pre- and post-planting treatment, paddy fields can be treated with 1-1.5kg/hm2 of chlorpyrifos in the early and middle stages of growth, while treatment at the bud stage can cause phytotoxicity. Weeds can be treated with 0.5-1kg/hm2 of chlorophos before their leaves, but this method It is harmful to carrots, tomatoes and cotton.
