目前,很多施药人员在喷施除草剂时都不单独配制稀释液,而是直接将除草剂加入喷雾器中。为了提高防治效果,配药过程中必须注意以下4个问题: 一、除草剂的剂型。除草剂不同剂型的配制方法不一样。例如乳剂、水剂和胶悬剂等,可采用一步稀释法配制,即将一定量的除草剂直接加入喷雾器中稀释。72%都尔乳剂、90%禾耐斯乳油都可采用这种方法。而可湿性粉剂、干燥悬乳剂等剂型,必须采用两步稀释法配制:第一步是按要求准确称取除草剂,加少量水
At present, many pesticide applicators do not formulate the diluent separately when spraying the herbicide, but directly add the herbicide to the sprayer. In order to improve the control effect, the pharmaceutical process must pay attention to the following four questions: First, the herbicide dosage form. Preparation of different formulations of different formulations of different herbicides. For example, emulsions, aqueous and gel suspensions can be prepared by a one-step dilution method. That is, a certain amount of herbicide is directly diluted into a sprayer. 72% Bourou emulsion, 90% Wo Ness EC can use this method. The wettable powder, dry suspenders and other dosage forms, must be prepared by two-step dilution method: The first step is the required weighed accurately weighed, add a small amount of water
