fungicide | bromonitrile is also known as charcoal terling, which is safe for human, livestock and ecological environment. Bromonitrile has low toxicity and high safety. It is a broad-spectrum fungicide that can inhibit or kill bacteria, fungi and algae organisms. It has unique protection, systemic treatment and eradication functions. It is suitable for all kinds of fruit trees, vegetables and The fungal and bacterial diseases of various crops such as tobacco and medicinal materials have significant effects and long duration. The agent can be quickly absorbed by the cell and conduct in the cell, and interfere with the normal development of the cell, so as to achieve antibacterial and bactericidal effects. It can also stimulate the activity of various enzymes in crops, increase photosynthesis, thick green leaves, strong plants, and increase crop yield. This product is a low toxic preparation. The preparations include 25% wettable powder and 25% emulsifiable concentrate. |
discovery history | bromine nitrile is a microbicide more effective than mercury preparation selected from more than 30,000 chemicals by Merck company (now reorganized as gentia company) in the 1970 s. It has the ability to kill mutant bacteria, inhibit the growth of bacteria, fungi and algae, and is a new type of fungicide with high safety. Bromonitrile has been certified as safe by the U.S. Environmental Protection Agency (EPA) and the U.S. Food and Drug Administration (FDA). Three times the concentration of bromonitrile is milder than soap in irritating human skin. Acute percutaneous LD50>10000mg/kg,C14 tracer shows that 87% is excreted in urine, and the rest is metabolized. It is safe for birds and fish within the concentration. It is a novel compound with low toxicity and broad spectrum with sterilization, mildew prevention and algae killing properties. It can inhibit and eradicate the growth of bacteria, fungi and algae, and is suitable for anti-corrosion, anti-mold and industrial wastewater treatment of textiles, leather, etc. It is also used in the production of medicine and cosmetics abroad. China's Shanghai Pesticide Research Institute began to study the production of bromine nitrile in the early 1980s. In 1989, it passed the small test technical appraisal organized by Shanghai Chemical Industry Bureau. Yancheng Longyue Pesticide Co., Ltd. transferred the small test technology from Shanghai Pesticide Research Institute in 1990. In 1991, it organized the installation for a pilot test and produced bromine nitrile original drug, successfully filling the gap in the production of this product in China. It is mainly used in the prevention and control of crop diseases, algae killing in fish ponds and industrial wastewater treatment in China. It is currently the specific agent for the prevention and control of various crop anthracnose in domestic fungicides. |
use method | (1) use method can effectively prevent grape anthracnose, black pox, downy mildew, white rot, anthracnose of apples and pears, scab, ring rot, spotted defoliation, anthracnose of watermelon and cucumber, vine blight, wilt, powdery mildew, downy mildew, etc. At the beginning of the disease, 25% bromonitrile wettable powder was sprayed 800~1 200 times. (2) precautions ① cannot be mixed with strong alkali and strong acidic agents. ② the medicine should be sealed and stored in a cool, dry place away from children, food, feed and fire. ③ it is not suitable to spray too many times or use it for a long time year by year, which will cause drug resistance. |
use | broad-spectrum, low-toxicity antiseptic, mildew-proof, algae-killing and fungicide. It can inhibit and kill the growth of bacteria, fungi and algae. It is suitable for anti-corrosion and anti-mold in textiles, leather, and industrial water to kill algae. It is effective against fruit trees, citrus, rubber, cucumbers, peppers, tomatoes, watermelons, vegetables and other crop diseases, especially anthracnose. It can also be used to prevent and treat scab, gray mold, scab, downy mildew, soft rot, and root swelling. The recommended concentration is 500~833mg/L, I. e. 300~500 times the liquid. For example, to prevent and control apple anthracnose, spray once every 7~10 days, a total of 3~4 times, the amount of medicine depends on the size of the fruit tree. widely used as fungicides in textiles, cosmetics, films, coatings, crops and other fields, bactericidal algicide for circulating water treatment, oil drilling water injection agent, etc. It is used as an anti-mold preservative for film, leather, paint, needle textiles, cosmetics, etc., as well as a fungicide for oil drilling water injection and industrial circulating water It is a high-efficiency and broad-spectrum fungicide. It has broad-spectrum activity against bacteria, fungi, and algae. It can be used for industrial water treatment, agricultural sterilization and environmental sanitation disinfection. It is a broad-spectrum, high-efficiency and low-toxicity fungicide, it can inhibit and eradicate the growth of fungi, bacteria, and algae, has a good control effect on crop diseases, and has special effects on anthracnose. It is widely used in fruit trees, grapes, vegetables, cotton, peanuts, watermelons, tobacco, tea trees, flowers and other crops to prevent anthracnose, scab, powdery mildew, rust, blight, cataplomeria, rhizome rot, canker, bacterial wilt, angular spot and other fungal and bacterial diseases. The application method is flexible, foliar spray, seed treatment and soil root irrigation all show good control effect. It is also suitable for algae control in lake environment treatment to improve the water quality of fishing ponds. Textiles, leather and other anti-corrosion, anti-virus, etc. |
Production method | 2-methylene glutaronitrile is prepared from acrylonitrile, and then bromine is added to obtain bromonitrile. |
