Method for preventing and treating powdery mildew on basis of electrolytic functional water

Abstract

The invention particularly relates to a method for preventing and treating powdery mildew on the basis of electrolytic functional water, and belongs to the field of agricultural planting. The method includes steps of firstly, injecting sodium chloride (edible salt) along with underground well water or drinking water into the neutral electrolytic functional water and the acidic electrolytic functional water in electrolytic functional water generators according to a proportion of 0.1%-0.2%; secondly, spraying the electrolytic functional water on plants, which are naturally affected with the powdery mildew, by the aid of handheld atomizers or micro-sprinklers once on a daily basis; thirdly, spraying the electrolytic functional water on field planting recovered seedlings (which are not naturally affected with the powdery mildew) by the aid of the handheld atomizers or the micro-sprinklers once every 3 hours. The underground well water or the drinking water is treated by RO (reverse osmosis) water purifiers. The neutral electrolytic functional water and the acidic electrolytic functional water are generated after electrolytic reaction is carried out. The spray usage of the electrolyticfunctional water sprayed at the second step is 0.2L-0.4L / plant in each spraying procedure. The spray usage of the electrolytic functional water sprayed at the third step is 0.2L-0.4L / plant in each spray procedure. The method has the advantages that the method is low in cost and free of chemical pesticide residues and is safe, existing chemical pesticides can be replaced, and excellent effects of preventing and treating the powdery mildew can be realized by the method.

Description

technical field [0001] The invention relates to a method for preventing and treating powdery mildew, and relates to the field of agricultural planting, in particular to a method for preventing and controlling powdery mildew based on electrolyzed functional water. Background technique [0002] Powdery mildew is a pathogenic fungus that produces powdery symptoms on the surface of plants. It is an obligate parasitic fungus with strong parasitic ability. After the germination of mycelium or conidia, it does not need to go through the wound, but can directly invade the host organ through the stomata or directly. Epidermis, the thinner and tenderer the epidermis of the organ of the host plant, the higher the probability of occurrence of powdery mildew and the degree of damage. Under normal circumstances, an infection cycle can be completed in 10 days. Once a crop is infected with powdery mildew, it develops rapidly and is difficult to eradicate. Often cause serious impacts, among ...

At present, the treatment methods basically use chemical preparations or pesticides. The treatment time is generally selected in the early stage of powdery mildew, that is, when powdery mildew spots appear on the leaves. Once the disease spots expand, the disease resistance will decline greatly. When it is blocked by a large number of leaves, it is difficult to spray the pesticide evenly, and it is very difficult to control it. At present, chemical pesticides such as carbendazim, fenoxenin, ether phenol, and chlorothalonil are mainly used for control. Although they have played a role in preventing and controlling powdery mildew However, the powdery mildew bacteria are prone to develop resistance due to the continuous use of chemical pesticides, and many farmers use only a single drug to prevent and control powdery mildew, often using one agent multiple times, so that the resistance of the bacteria will only become stronger
