Crop pests and diseases are one of the important limiting factors for the sustainable development of agricultural production. In order to control the occurrence of pests and diseases and ensure the stable development of agricultural production, the use of chemically synthesized pesticides is also increasing. However, the extensive use of chemical pesticides in controlling pests and diseases has also caused a series of problems. The most important of these is the serious environmental problems caused, especially the pollution of water resources, which has seriously threatened human health and the natural environment on which it relies for long-term survival. Therefore, finding effective pest control methods that can control the occurrence of diseases and insect pests without causing serious harm to the environment has become the direction that many people have been tirelessly striving for.  
 
 

Due to its low pH value and strong oxidation and acidification effects, strongly acidic electric functional water mainly controls the survival and reproduction of bacteria, and does not contain substances that are difficult to degrade and will remain in the environment for a long time, which are harmful to humans, animals and plants. Therefore, its impact on the environment mainly involves slightly changing the pH value of soil or water sources to increase their acidity. In the northern regions, this kind of impact can be completely disregarded. Because the soil in the north is mostly composed of limestone matrix, which is highly alkaline. Proper supplementation of acidic substances can neutralize the alkalinity, which is beneficial for the release and absorption of many nutrients, resulting in more favorable growth and development of crops. This preparation is used on some highly acidic soils in the south, although it does not produce the same beneficial effects as in soils in the north. However, due to the limited dosage of this preparation each time, the harm to the environment and water resources can be almost ignored.

In addition to the application of disease prevention and control in agriculture, research has shown that strong acidic electrically functional water also has a wide range of uses in other fields. It can be used for disinfection of medical equipment, medical devices, medical staff and patients, as well as diagnosis and treatment tables, operating rooms, and bed walls in healthcare. It can be used for sterilization of food processing raw materials and finished products, as well as sterilization of kitchen utensils, tableware, and fresh produce in food processing and daily life

The preparation of strongly acidic electrically functional water is relatively easy. The equipment used is just an electrolysis device. The raw materials used are only ordinary water and relatively pure edible salt. RCS Industrial Technology Co., Ltd. in Japan has also developed various types of equipment for producing strong acidic electrically functional water. There are equipment for mass production, as well as small devices suitable for individual use on farms or even in households. Having a strong acidic electric functional water production equipment. Ordinary farms, orchards, hospitals, canteens, and even households can prepare strong acidic electric functional water at any time when they need it. It is very economical and convenient.
The byproduct of preparing strong acidic electrically functional water is the strong alkaline water generated at the cathode of the electrolysis equipment. The pH of the strongly alkaline water produced is above ll and the acidification reduction potential is below -800mV. This byproduct also has many uses. For example:
(1) Used for food preservation. Wash vegetables and fruits thoroughly and rinse them with strong alkaline water to extend their shelf life.
(2) Tableware cleaning. It is difficult to remove fat and protein stains attached to tableware with clean water. It is easy to clean with strong alkaline water

(3) Used for preventing acidification of metal, especially iron-based medical devices. These medical devices can be disinfected with strong acidic electric functional water and rinsed with strong alkaline reducing water to neutralize and prevent acidification.
