Background
For fungal diseases on fruit trees and vegetables, the use of copper sulfate solution for control has a long history. When the copper sulfate solution is sprayed on the surface of a plant, copper ions in the copper sulfate solution enter pathogenic fungi or bacteria and are combined with biological groups to form substances such as a copper complex and the like, so that protein is denatured, metabolism is hindered and inhibited, germs die, and the purpose of sterilization is achieved.
The copper sulfate solution is prepared from copper sulfate and water according to a certain proportion. The proportion of copper sulfate and water is changed according to the spraying object, season and temperature, and the copper sulfate and water are prepared for use when in use, and are easy to deteriorate and lose efficacy if not used after long-term preparation. This results in not only troublesome use process but also a great decrease in the bactericidal effect due to the greater randomness of the copper sulfate solution when it is prepared. Meanwhile, if the copper sulfate solution is incorrectly prepared and is not standard in the using process, the leaves of the plants are easily roughened, the photosynthesis is reduced, and the growth of the plants is not facilitated. The copper sulfate solution is used as a bactericide slowly at present for various reasons, and cannot keep pace with the demand of the times.
In order to solve the problems of using a copper sulfate solution as a bactericide in the process, a pesticide manufacturer produces a copper calcium sulfate wettable powder with 77 percent of active ingredients, wherein a copper calcium sulfate raw pesticide is used as a main ingredient and accounts for 77 percent, and other additives are added. The 77% copper calcium sulfate wettable powder has the excellent sterilizing characteristic of copper sulfate, can overcome various defects of the traditional copper sulfate as a sterilizing agent in the using process, has flexible and various using methods, simple and convenient operation, high efficiency and reliability, can be used for preventing and treating diseases on the ground by spraying besides being used on plants and preventing the spread of soil diseases and insect pests. The composite calcium ion bactericide has stable bactericidal effect and longer lasting period, not only has the performance characteristics of the copper sulfate solution as the bactericide, but also can supplement nutrient calcium elements required by plants in the sterilization process due to the composite calcium ions, has the calcium supplementing effect like a human body, can improve the disease resistance of the plants and promote the growth of the plants, has the advantage of no copper sulfate solution, and is an excellent substitute of the copper sulfate solution as the bactericide.
The main component of the 77% copper calcium sulfate wettable powder is copper calcium sulfate, most of the copper calcium sulfate used by the domestic 77% copper calcium sulfate wettable powder manufacturer is imported from abroad, the cost is high, and the procurement time is long.
