What is carbendazim
is also known as cotton wilt and benzimidazole 44. Carbendazim is a broad-spectrum fungicide, and has a control effect on diseases caused by fungi (such as semi-known fungi, ascomycetes) in various crops. It can be used for foliar spray, seed treatment and soil treatment. It can effectively control a variety of crop diseases caused by fungi and is widely used in China.
Carbendazim mode of action
It interferes with the formation of spindles in mitosis of pathogenic bacteria, affects cell division and plays a bactericidal effect.
Solubility at 24 °C: 29mglL (PH4) of water, 5g / L of dimethylformamide, slightly soluble in other organic solvents. Stable below 50 °C for at least 2 years. Slowly decompose in alkaline solution, decompose faster with increasing pH, lose activity with decreasing pH, take 7 as the benchmark. Stable formation of soluble salts in acids.
Carbendazim chemical name
English common name carbendazim
Chemical name: N- (2-benzimidazolyl) -methyl carbamate
Chinese alias: befentinyl; methyl-1H-2-benzimidazole carbamate; methyl N- (2-benzimidazolyl) carbamate; methyl N- (2-benzimidazolyl) carbamate Ester; methyl-benzimidazole-2-carbamate
Carbendazim is a benzimidazole, a high-efficiency, low-toxic systemic fungicide. Due to its apparent tip conductivity, it is also used as a seed dressing and irrigation soil in addition to foliar sprays. Spectral systemic fungicides absorbed by seeds, roots and leaves can be carried out in crops, have protective and therapeutic effects, and have a long residual time. Carbendazim can be widely used to control: wheat black spot, rice blast / shadow blight, pear black spot, apple brown spot, grape black pox / white rot / anthrax, early tomato blight, melon powdery mildew, beet brown spot, Fusarium melon wilt, Cotton seed wilt / anthrax, peanut black spot, stem rot, sweet potato black spot, rose brown spot, clivia leaf spot, orchid anthracnose spot, etc.
Carbendazim is relatively low in toxicity, and it is not a problem for larger amounts when used as an adult plant, when the solution looks like milk with water. For seedlings, the concentration should be as low as possible, and the meaning is fine. After all, the resistance of the seedlings is relatively poor.
In general, if root treatment is used, 8g of carbendazim can be mixed with 200ml of water. If it is used for soil mixing, just add a little depending on the amount of soil. -On the one hand, because there are fewer new soil bacteria, on the other hand, because the plant will grow new roots after planting, and the resistance is relatively poor.
Carbendazim wettable powder is a systemic fungicide that is effective against some pathogenic fungi and most pathogenic fungi of ascomycetes. The mechanism of action is to interfere with the mitotic process of the cell. This product is mainly used to control crop diseases caused by fungi.
1.Early blight of tomato, powdery mildew of melons, brown spot of sugar beet
From the initial stage of the disease, use 50% wettable powder 800-1000 times liquid, spray every 1-10 days to prevent and control, and spray 3-5 times, can prevent and control.
2. Control of Fusarium wilt before transplanting and cultivating cucumbers and watermelons
Use 1-1.5 kg of 50% wettable powder per acre, mix well with 25-30 kg of fine soil, and spread it evenly in the planting ditch or hole. During the fruiting stage, irrigate the roots with 1000 times the 50% wettable powder.
3. Cotton seedling blight, anthracnose
Use 1 kg of 50% wettable powder, 10-20 kg of water, 100 kg of cotton seeds, sow after 6 hours of pile up, or soak seeds in 250 times of 50% wettable powder for 24 hours, dry and sow.
4, peanut black spot, stem rot
Use 50% wettable powder 0.5-1 kg, peanut 100 kg, mix well and sow.
5. Wheat scab
At the heading stage of wheat, spray with 500-1000 times liquid of 50% wettable powder, spray once every 5-7 days, spraying 75-100 kg of liquid medicine per mu each time
6. Rice sheath blight
Use 500-1000 times solution of 50% wettable powder, spray and control once at the end of tillering stage and booting stage of rice.
7, sweet potato black spot
Before transplanting, immerse the base of sweet potato stem with 3000-4000 times of 50% wettable powder for 5 minutes.
According to the situation, spraying with 50% wettable powder 500-1000 times liquid can prevent powdery mildew of various flowers and rose leaf spot, clivia leaf spot, orchid anthracnose, leaf spot, etc.
9, pear scab
After the pear tree germination and Xiehua, spray each time with 500 times of 50% wettable powder, and spray it once every 7-10 days, 23 times in succession.
10.Apple brown spot
Use 50% wettable powder 500-800 times liquid, spray control from the beginning of apple onset, and spray again after 7-10 days.
11. Grape black pox, white rot, anthracnose
Spray from 500-1000 times of 50% wettable powder every 10-15 days from the leaves of grapes to before the coloring of pupae.
Low toxicity to humans, livestock, fish, bees, etc. Irritating to the skin and eyes, dizziness, nausea and vomiting due to oral poisoning.
Carbendazim has a control effect on diseases caused by fungi (such as semi-known fungi and ascomycetes) in various crops. It can be used for foliar spray, seed treatment and soil treatment. It can effectively control a variety of crop diseases caused by fungi. It is widely used in China, but its residues can cause liver disease and chromosome aberration, and are toxic to mammals.
Irritating to the skin and eyes, dizziness, nausea and vomiting due to oral poisoning.
Carbendazim Poisoning Treatment
For skin-induced poisoning, immediately remove clothing, shoes, and hats that are in contact with the skin, and rinse repeatedly with warm water. If pesticides are splashed into the eyes, rinse immediately with normal saline, and then drip 2% cortisone or 0.25% chloramphenicol eye drops. After that, if the poisoning is serious, you can use the corresponding antidote according to the type of pesticide.
The poisoning caused by inhalation should be taken away from the site of poisoning as soon as possible, to a place with fresh air, take off protective clothing, gloves, masks, etc., loosen the collar and keep breathing smooth. Then use the appropriate antidote according to the degree of poisoning and the types of pesticides that cause poisoning.
Carbendazim poisoning prevention
Carbendazim can be mixed with general fungicides, but when used with insecticides and acaricides, it should be used with each other.
Long-term single use of carbendazim can easily cause resistance to bacteria, and it should be used alternately or mixed with other fungicides.
When it is used for soil treatment, it is sometimes decomposed by soil microorganisms, reducing the efficacy. If the soil treatment effect is not satisfactory, other methods of use can be used instead.
The safety interval is 15 days.
Carbendazim is a fungicide that is widely used in pest management of fruit trees, vegetables, flowers and agricultural crops. Although the contact with carbendazim is usually not high, it is harmful to the human body after long-term exposure to the drug. Long-term intake of a large amount of carbendazim can accumulate in the human liver and cause symptoms such as nausea and dizziness.
