The difference between Propineb and Mancozeb
Propineb is a new type, high efficiency, low toxicity, broad-spectrum carbamate protective organosulfur fungicide. The bactericidal principle is the same as that of mancozeb, mainly to inhibit the oxidation of pyruvate in pathogenic bacteria. The process of propine zinc increases the zinc content, which greatly improves the protection effect. The difference from mancozeb is that it has a high content of zinc ions and does not contain manganese ions.
Zinc is a protective organosulfur fungicide. The pure product is off-white powder, the industrial product is off-white or light yellow powder, with sulfur smell. Unstable under conditions of alkaline, high temperature, humidity, and sunlight. Low toxicity to humans and animals, but irritating to human skin, nose and throat. It is safe and non-polluting to plants. The main dosage forms are 60%, 65% and 80% wettable powder, and 4% powder.
Zinc is safe for plants and has active chemical properties. It is easily oxidized into isothiocyanate compounds in water. It has a strong inhibitory effect on enzymes containing -SH groups in pathogenic bacteria, and can directly kill pathogenic spores and inhibit the germination of spores. , Prevent pathogens from invading plants, but have less killing effect on pathogenic mycelium that invades plants.
Pre-prevention of potato early blight, late blight, tomato early blight, late blight, spot blight, leaf mold, anthracnose, gray mold, eggplant cotton blight, brown spot, cabbage, radish, cabbage downy mildew, black spot disease, white spot, soft rot, black rot, melon anthracnose, downy mildew, blight, creeping blight, winter melon blight, bean anthracnose, brown spot, rust, fire disease, etc., use 65% Zinc wettable powder 500-700 times liquid spray control.
Precautions
(1) Cucurbit vegetables are sensitive to zinc, and the concentration should be strictly controlled when using the medicine, and it should not be too large.
(2) Do not mix with alkaline pesticides.
The pure product of mancozeb is white powder, and the industrial product is off-white or light yellow powder, with the smell of rotten eggs, hardly soluble in water, insoluble in most organic solvents, but soluble in pyridine, not sensitive to light, heat and humidity Stable, easy to decompose carbon disulfide, easy to decompose and release carbon disulfide when encountering alkaline substances or copper, mercury and other substances, and reduce the effect, low volatility. Mancozeb is a protective fungicide with high efficiency, low toxicity and broad spectrum. The mechanism of action is to bind to the sulfhydryl group in dilipoic acid dehydrogenase involved in the pyruvate oxidation process, thereby inhibiting the oxidation of pyruvate in bacteria. It can be used in combination with systemic fungicides to delay the development of drug resistance. The so-called protection is to provide Zn elements for plants. In addition to solving the symptoms of zinc deficiency, it can also enhance the ability of plants to resist diseases, so as to relatively play a bactericidal effect.
Control objects: pear scab, citrus scab, canker, apple leaf spot, grape downy mildew, litchi downy mildew, phytophthora, green pepper blight, cucumber, melon, watermelon downy mildew, tomato blight, cotton Boll rot, wheat rust, powdery mildew, maize spot, stripe spot, tobacco black shank, yam anthracnose, brown rot, root neck rot, spotted leaf spot, etc.
Precautions
Eggplant is particularly sensitive to mancozeb. After spraying, the manganese element accumulates in the leaves, resulting in excess manganese. The leaves of the light ones turn yellow, and the leaves of the severe ones start to fall from top to bottom. It is recommended that chlorothalonil should be the main fungicide used on eggplants and melons, and mancozeb should not be used or used less.
smell different
Zinc - sulfur smell
Mancozeb - smell of rotten eggs
different content
Mancozeb zinc content 2.55% Zinc content 8%,
The effect is different
The manganese ions in mancozeb were proposed and evolved into mancozeb. However, the use of mancozeb has proved that mancozeb does not have a broad bactericidal spectrum, and its protective ability is general and has no therapeutic effect on fungi. It only contains The amount of zinc is a little higher than that of mancozeb, which is a variety that the market is preparing to eliminate.
Combining zinc ions and manganese ions in ordinary mancozeb together, it will not be a single manganese ion, and there is almost no phytotoxicity. This is complex mancozeb. Compared with ordinary mancozeb, the advantages of complexed mancozeb are safety and high efficiency. Ordinary mancozeb (non-complexed) is easy to decompose manganese ions, which will lead to phytotoxicity. Mancozeb has higher zinc content, better protection effect, and has obvious effect of leaf greening and fruit surface brightening! It can increase crop yield and improve quality; The control effect is obvious and can reduce the killing effect on beneficial predatory mites.
Duration is different
Zinc sterilizes and supplements zinc. Both sterilization and zinc supplementation are quick-acting, and the drug effect is short, usually 5-7 days.
The manganese in mancozeb can control the release rate of zinc, making the drug effect more durable. Generally, the drug effect lasts for 10-15 days, which is longer than that of mancozeb.
