During this period of time, I heard that the bactericidal community enoyl morpholine and the rookie quinoline copper are hooked together all day, and the feelings are heating up. What I never imagined is that they are married, too crazy, this is simply gold. Partner... Don't be jealous, don't be embarrassed. Now it's useless to say that you are here. Let's introduce the "newcomers" in the sterilization industry.
About dimethomorph
Dimethomorph is a new type of systemic therapeutic low-toxic fungicide . Its mechanism of action is to destroy the formation of the cell wall membrane of the pathogen, causing the decomposition of the sporangia wall and causing the bacteria to die. In addition to zoospores formation and spore swimming period, it has effects on all stages of life history of oocysts, especially for the formation stage of sporangia and oospores. If the drug is used before the formation of sporangia and oospores, Spore production can be completely inhibited. The drug has strong systemic attraction, and the root can be applied to all parts of the plant through the root; the leaves can be sprayed into the interior of the blade. It has no cross-resistance with benzamide fungicides such as metalaxyl.
Dimethomorph is a special agent for controlling fungal diseases of Oomycetes, and for lower fungi such as downy mildew, Phytophthora capsici, late blight, plague (mold) disease, plague, rot, black shank Sexual diseases have a good control effect. Can be applied to grapes, lychee, cucumber, melon, bitter gourd, tomato, pepper, potato, cruciferous vegetables.
It is widely used for disease control of vegetable downy mildew, epidemic disease, seedling stage disease, tobacco black shank, etc. caused by the fungus of the genus Escherichia, with systemic activity. Under the premise of not considering the resistance of pathogenic fungi, the efficacy is higher than that of currently used metalaxyl, cymoxanil, ethylphosphorus, and vesyl cream.
It is well known that dimethomorph has a relatively high risk of resistance when used alone, so it is often used in combination with protective bactericides such as copper preparations, such as copper quinoline, to delay the production of resistance. For the quinoline copper please see below:
About Quinoline Copper
Quinoline copper is a clamped organic copper fungicide. It has many points of action to kill germs. It can not produce resistance after repeated use of pathogens, and has effective prevention and treatment effects on diseases in which conventional fungicides have developed resistance. Therefore, it has become a fungicide product widely used by farmers. The application of quinoline copper in agriculture is as follows:
At present, the diseases controlled by copper quinoline mainly include tomato late blight, bacterial ulcer disease, pepper disease, ulcer disease, scab, downy mildew, cucumber downy mildew, bacterial leaf spot, watermelon downy mildew. , anthracnose, bacterial fruit spot disease, downy mildew of melon, rot, bacterial fruit rot, potato late blight. The advantages of quinoline copper are quite obvious compared to other fungicides. It not only can kill germs, but also improve the quality of fruits and vegetables: the leaves of fruits and vegetables turn green and brighten, the surface of the fruit is smooth, no residual stains, and the coloration of the fruit surface is enhanced. It is a green pollution-free pesticide .
