LD50231mg/kg in rats, 125mg/kg in mice and 5050-100mg/kg in rats. Rabbit >400mg/kg. It has moderate irritation to skin and eyes. The inactive dose of dog feeding test in 2 years was 1.7 mg/kg on the first day and 25 mg/kg per day on the third generation of rats. No teratogenic, carcinogenic and mutagenic effects were observed in animal feeding test. Cyprinus carpio LC5040mg/L (48h), rainbow trout 45mg/L (24h). Partridge acute oral LD50270mg/kg. Low toxicity to bees.
It is found that the fast bromide salt exists in the form of monohydrate, and is crystal to white. The decomposition temperature is above 300 and the vapor pressure is 13.3 10-6Pa. It is slightly soluble in ethanol and other hydroxyl solvents, and is insoluble in non-polar organic solvents. The solubility in water at 20 C is 700g/L. It is stable in acidic and neutral solutions and is unstable under alkaline conditions.
Non selective contact killing herbicides are slightly conductive. After being absorbed by green plants, the electron transfer of photosynthesis is inhibited. The reduced bipyridine compounds are oxidized quickly in the presence of oxygen under the light-induced condition, forming active hydrogen peroxide.
The accumulation of this substance destroys the cell membrane of plants and causes the parts of plants to wither and yellowing. It can also be used as seed plant desiccant, potato, cotton, soybean, corn, sorghum, flax, sunflower and other crop deadening agents.
When dealing with mature crops, the remaining green parts and weeds dry quickly, and can be harvested early, with less seed loss. It can be used as an inhibitor of the inflorescence formation of sugarcane.

|Appearance||Grey to white power|
|A.I content, %||42.0min|
|Water insoluble, %||1.0max|
|Mode of Action||
A broad-spectrum, quick-acting, non-selective contact herbicide.
Be absorbed by green plant tissue quickly, it will be easy to loss efficiency after contacting the soil.
Vegetables, grains, cotton, orchard, sugar cane, peanuts, potatoes, and tree plantation areas;
postemergence around fruit crops, vegetables, trees, vines, grains, soybeans, and sugar cane.
And as a ripener and defoliant for soybean, cotton before harvesting.
It has quicker and better control effect on broad-leave weeds than paraquat.
Also used for general weed control on non-crop land.
e.g. Defoliation after rice harvesting: 450~600g a.i./ha.
Specific dosage depends on different situation.
|5. First Aid Measures|
|General advice: Consult a physician.|
If inhaled. If breathed in, move person into fresh air.
If not breathing, give artificial respiration
|In case of skin contact, wash off with soap and plenty of water|
|In case of eye contact, rinse thoroughly with plenty of water for at least 15 min.|
If swallowed, do NOT induce vomiting.
