Mancozeb, pure white powder, industrial product is gray-white or light yellow powder, rotten egg smell, insoluble in water, insoluble in most organic solvents, but soluble in pyridine, unstable to light, heat, humidity, easy to decompose carbon disulfide, alkaline substances or copper, mercury and other substances are easy to separate carbon disulfide and reduce efficiency, volatile is small. The so-called protection is to provide ZN elements for plants, in addition to solving the symptoms of zinc deficiency, to enhance the ability of plants to resist diseases, so as to play a relatively bactericidal role.

Market dosage forms. 70% and 80% mancozeb wettable powders.

Physicochemical properties. It is a complex of mancozeb and zepzeb, containing 20% manganese and zinc. The original ingredient is a grayish-yellow powder with a melting point of 192 to 204 (decomposition).

Solubility: insoluble in water and most organic solvents, soluble in strong chelating agent solution. It is usually stable in a dry environment, slowly decomposes in a heated and humid environment, and can cause combustion when decomposed by acid and alkali.

Prevention and control objects. Dysen zinc is mainly used for the prevention and control of vegetable downy mildew, charcoal disease, brown spot disease, etc. At present, it is an ideal agent for the prevention and control of tomato early blight and potato late blight, with a control effect of about 80% and 90% respectively, and it is generally sprayed on the foliar surface, sprayed once every 10 to 15 days.

1) To prevent and control tomato, eggplant, potato blight, charcoal and leaf spot, use 400 to 600 times of 80% wettable powder. Spray at the beginning of the disease, 3 to 5 times in a row.

2) To prevent and control vegetable seedling blight and cataplexy, use 80% wettable powder and mix seeds according to the weight of seeds.

3) To prevent and control melon downy mildew, charcoal disease and brown spot disease, spray with 400 to 500 times liquid, spray 3 to 5 times.

4) To prevent and control downy mildew of cabbage, sugar basket and spot disease of catkins, spray with 500 to 600 times of liquid, and spray 3 to 5 times.

5) To prevent and control Phaseolus vulgaris and red spot disease, spray with 400 to 700 times of liquid, and spray 2 to 3 times in a row.

Drug effects. Mancozeb is an excellent protective fungicide and is a low-toxicity pesticide. Due to its wide range of sterilization, not easy to produce resistance, the control effect is significantly better than other similar fungicides, so the international dosage is always a large-tonnage product.

At present, most of the compound fungicides in China are made of mancozeb processing, manganese and zinc trace elements have obvious effects on crops to promote growth and increase yield, through more than ten years of field application, the effect on the prevention and control of pear scab, apple spot defoliation, melon and vegetable blight, downy mildew, field crop rust, etc., without any other fungicides can effectively control the occurrence of diseases, and the quality is stable and reliable.

Main control objects: pear scab, citrus scab, canker, apple spot defoliation, grape downy mildew, lychee downy mildew, phytophthora mildew, green pepper blight, cucumber, melon, watermelon downy mildew, tomato blight, cotton boll rot, wheat rust, powdery mildew, corn spot, stripe spot, tobacco black shin disease, yam charcoal disease, brown rot, root neck rot, spot defoliation, etc.

1.Prochloraz is introduced in this beam.

Prochloraz, also known as methadone and methamamide, is a broad-spectrum, high-efficiency, low-dose, safe fungicide and insecticide, suitable for the control of crop diseases and pests. Its mechanism of action is to inhibit the oxidative phosphorylation of bacteria to achieve the purpose of killing germs. Prochloraz is not only highly lethal to diseases, but also non-polluting and harmless to the environment and human health, so it is widely used in agricultural production around the world.

2.The main control scope of prochloraz.

Prochloraz mainly controls pests and diseases in fruit and vegetable crops such as rice, wheat, rape, tomato, potato, sugar beet, cucumber, apple, peach, wolfberry, stray flower, melon, strawberry, etc. It has a wide range of action, fast insecticide and significant control effect, which can effectively control the occurrence of diseases and improve the yield and quality of crops during the growth of crops.

3.How to use prochloraz.

The use of prochloraz is divided into two ways: spraying and soaking.

1) Spray. After diluting prochloraz, spray on the surface of crop leaves, stems, fruits and other surfaces to achieve pest and disease control. It is recommended to spray when the temperature is suitable (20 30) and the wind is small, and pay attention to pre-coating pesticides before spraying to increase the adhesion of prochloraz and improve the control effect.

2) Soaking seeds. Soaking prochloraz directly in the seed or seedling growth substrate can enhance the disease resistance in the subsequent crop growth process and prevent the occurrence of pests and diseases. However, it should be noted that the soaking time should be mastered when soaking seeds, not too long, so as not to cause the death of seeds due to the high concentration of prochloraz.

4.Precautions for prochloraz.

1) The concentration of prochloraz should not be too high to avoid harm to crops. When using prochloraz, it must be applied in accordance with the prescribed dosage and method, and pay attention to cleaning the application tools and protective equipment and protecting the environment in time after application.

2) Pay attention to safety during the use of prochloraz, and do not directly contact prochloraz, so as not to cause harm to the human body. In case of accidental contact, rinse immediately with water and treat under the guidance of a doctor.

3) Mijuleaz is suitable for a variety of crops, but the use methods and dosages of different crops are different, so you should read the product instructions in detail before use, and carefully grasp the use methods and precautions.
