Orchard sprayer manufacturers introduce the details of spraying in the orchard

       1. Reasonable mixing

　　Fruit trees are often harmed by a variety of pests and diseases during the growing period. If each pest must be controlled by a single spray, it will be more troublesome.Therefore, 2-3 kinds of pesticides are often mixed and used in production at a certain dose to achieve the purpose of treating multiple diseases and insects in one spray.The mixing and mixing of pesticides cannot be random, but there are strict regulations.The principle is: first, it must have a synergistic effect; second, it can expand the target of prevention and control; third, the mixed agent does not cause medicinal harm to plants, and the toxicity to humans and animals cannot be higher than that of a single dose; fourth, the mixed single dose can be dissolved in water, the physical and chemical properties are stable, and the active ingredients are not decomposed; fifth, the cost of the mixed agent cannot be increased.The purpose of mixing pesticides must first be clear, and the agents should be selected according to the principle of mixing and the object of prevention and control.At the same time, pay attention to similar agents, pesticides with similar modes of action and prevention effects, and do not mix with each other. After mixing, not only will the prevention effect not be improved, but the cost will be increased, and the residual amount on the fruit will also increase.Secondly, the mixed medicine should be used now, and it should not be left for too long.

        2. Pay attention to the method of application and the quality of spraying

　　The medicine should be applied according to the place of origin and harmful habits of the pests and diseases. Some pests and diseases are harmful on the front of the leaves, some are harmful on the back of the leaves, and some are harmful on the young shoots, branches, and fruits.Therefore, the key parts of the spray are different.When spraying, pay attention to uniform spraying, and do not leak, spray less or spray again. Do not spray in windy or rainy weather. Powder can be sprayed in the morning and evening when the dew is heavy, but do not spray liquid agents.

        3. Drug hazard prevention and safety protection

　　In the process of pesticide application, to prevent the occurrence of drug harm, the key lies in correctly mastering the method of pesticide use, and the following points should be paid attention to：

　　First, don't use the wrong medicine, and don't apply expired and deteriorated pesticides.；

　　Second, don't blindly pursue new pesticides. You must test the mixing of pesticides first and then mix them.；

　　Third, we must accurately grasp the concentration of administration, and do not arbitrarily increase the dosage and the number of applications.；

　　Four, avoid taking medicine during the sensitive period of fruit tree growth and development；

　　5. Pesticides should be stirred evenly when they are formulated, and sprayed evenly when they are applied. They should not be re-sprayed at will, and the remaining pesticides should not be dumped randomly.；
