| Physical and Chemical Properties | Chemical properties of dibromo dibromide dihydrate in the form of a single compound, white to yellow crystals. Above 300 deg c decomposition, vapor pressure 13.3 x 10-6pa. Slightly soluble in ethanol and other solvents with hydroxyl groups, insoluble in non-polar organic solvents. The solubility in water at 20 °c was 700g/L. Stable in acidic and neutral solutions, unstable in alkaline conditions. |
| Use | Non-selective contact herbicide, slightly conductive. After being absorbed by green plants, the electron transfer of photosynthesis is inhibited, and the reduced bipyridine compound is rapidly oxidized in the presence of oxygen under light induction to form active hydrogen peroxide, the accumulation of this material makes the plant cell membrane damage, the drug receiving parts of the yellow. Suitable for broad-leaved weeds dominant plots of weed control; Can also be used as seed plant drying agent; Can also be used for potato, cotton, soybean, corn, sorghum, flax, sunflower and other crops; when dealing with mature crops, the residual green part and weeds quickly dry, early harvest, seed loss is less; Can also be used as an inhibitor of sugarcane inflorescence formation. Because of the inability to penetrate the mature bark, there is no damage to the underground pole stem. For the promotion of crops dry, the amount of 3~6G active ingredients/100. For farmland herbicidal, no-tillage herbicidal amount of summer maize is 4.5~6G active ingredient/100, Orchard is 6~9 active ingredient/100. Do not directly spray the young trees of crops, because of exposure to the green part of the crop will produce damage. Buneimen Chemical Company of the United Kingdom has been allowed to use Linon 20% water agent to carry out the wheat leaf-drying test in China. |
