Introduction | Mancozeb pure is white powder, industrial products are off-white or light yellow powder, with a smell of bad eggs. It is insoluble in water, insoluble in most organic solvents, soluble in pyridine, unstable to light, heat and humidity, and easily decomposed to form carbon disulfide (CS2) when exposed to alkaline substances or copper and mercury, decreased efficacy. |
Application | Mancozeb is a broad-spectrum multi-site protective fungicide, which can be used to control vegetables, many diseases of food and fruit trees. It can be used alone, and can be used with a variety of systemic fungicides, can obtain the desired control effect, and is not easy to produce resistance. Mancozeb can meet the needs of farmers and the market from many aspects, reduce the cost of drug use, and solve the problem of pathogen resistance. |
toxicity information | Mancozeb has low toxicity in mammals, acute oral toxicity in rats LD50> 5 000 mg/kg, inhalation Toxicity LC50 value> 5.14 mg/L. It is non-irritating to rabbit skin and eye irritation is grade III (EPA grade). Chronic toxicity studies of Mancozeb have found that long-term exposure to Mancozeb may cause neurodegenerative diseases such as Parkinson's disease. |
Use | This product is a broad-spectrum foliar protection fungicide, which is widely used in fruit trees, vegetables and field crops, can control a variety of important leaf fungal diseases, such as wheat rust, corn leaf blight, potato blight, fruit scab, anthracnose and so on. Its dosage is 1.4-1.9 (active ingredient)/hm2. Because of its wide use and good efficacy, it has become an important variety of non-systemic protective fungicides. With the internal absorption of fungicides or mixed use, there may be a certain market. is an efficient, low toxicity, broad-spectrum protective fungicide, used for wheat, corn, fruit and other crops of sterilization and disease prevention is a broad-spectrum fungicide, for the prevention and control of various diseases caused by fungi |
production method | a slurry-like manganese-substituted solution was prepared by reacting the same amount of sodium substituted with concentrated manganese chloride solution. The product is then spray dried by reacting the manganite with a zinc nitrate or zinc sulfate solution. Raw material consumption quota: ethylenediamine (98%)310kg/t, carbon disulfide (99%)870kg/t, sodium hydroxide (30%)420kg/t, manganese sulfate (98%)1020kg/t, zinc sulfate (96%)80kg/t. |

A gray-yellow powder. Melting point 136 °c (decomposition); Flash Point (Open Cup) 173.8 °c. Insoluble in water and most organic solvents. It is stable under normal storage conditions, but decomposes at elevated temperatures under humid and acidic conditions. Unstable to acid and alkali.
by ethylenediamine and carbon disulfide interaction, in the presence of NaOH to generate sodium substituted, sodium substituted and manganese sulfate to generate manganese substituted, manganese substituted and zinc sulfate effect of manganese substituted manganese.
A broad-spectrum protective fungicide. Widely used in fruit trees, vegetables and field crops, can control a variety of important leaf fungal diseases. With 70% wettable powder 500~700 times liquid spray, can control vegetable early blight, gray mold, downy mildew, melon anthracnose. Can also be used for the prevention and control of fruit scab, brown spot disease, anthracnose and so on.
The oral LD50 of rats was 8000 ~ 10000mg/kg (12800 ~ 14000mg/kg), and the oral LD50 of rabbits (48h) was 4.0mg/L. It has a stimulating effect on rabbit skin and mucosa.
