Copper bactericide is a commonly used fungicide. It not only has a preventive effect on fungal diseases , but also has certain effects on the prevention and treatment of bacterial diseases. What are the characteristics of copper bactericides? The following is a small series of pesticide networks . Let's take a look.
Copper bactericide can not only prevent fungal diseases, but also prevent and cure bacterial diseases; it has both protective and preventive effects, and has certain therapeutic and eradicative effects; it can be used for healing wounds, sterilization and anti-inflammatory, and treatment. Some skin diseases; can also be used for preservation and preservation of fruits during storage.
Because the copper fungicide has the characteristics of low toxicity, pollution-free and environmental protection, it has become the first choice for producing green food and organic fruits. The copper bactericide sprayed on the crop is strong, forming a layer of film, resistant to rain and scouring, long-lasting effect, can prevent the invasion of bacteria for a long time, so the control effect is better. With copper bactericides , it is difficult to develop disease resistance.
Copper bactericides have so many advantages that they will inevitably lead to the development and utilization of such preparations. Currently, inorganic copper preparations have been developed: basic copper sulphate (bordeaux liquid), copper oxychloride (king copper), cuprous oxide. (Bronze master, backing), copper hydroxide (can kill, Guan Guqing, Feng Huan, Rui Fu 2000) and so on. Organic copper preparations include: thiabium copper, copper amide (xiaoxianling, gram-producing hormone, copper sulphate), fatty acid copper, copper rosinate (green copper), copper succinate, copper dibasic acid Copper acid citrate, BT), copper soap liquid, copper amide, and the like. The development and utilization of organic copper preparations has become a hot spot for the production of fungicides. At the same time, a variety of copper preparations and other fungicides have been mixed, such as: morpholinium hydrochloride, copper, nail cream, copper (remediation copper), nail cream, aluminum, copper, copper, zinc, zinc Drying, anti-dry spirit), mixed amino acid copper · zinc · manganese · magnesium, plant disease, copper humate (843 healing agent).
However, the long-term continuous use of copper bactericides has a problem that cannot be ignored, that is, it is easy to induce the proliferation of mites and cause mites. Observed in many years of production, long-term use of copper fungicides on cotton to prevent angular spot, seedling anthracnose, and blight are easy to cause early emergence and multiple occurrence of cotton leaf mites, causing cotton deciduous stalks; beans, peppers, tomatoes, The use of copper bactericides on eggplant and other vegetables to control epidemic diseases, anthracnose, and bacterial wilt, etc., may cause a large number of oviposition and value-added of the sassafras, resulting in dry and detached leaves.
