| Use | a selective, systemic-conducting type of triazobenzene herbicide. It can be absorbed by mixed grass roots and leaves, and transmitted to the whole body of the plant, inhibit the photosynthesis of weeds, and make the leaves green and yellow and die. Mainly used for rice, can also be used for corn, soybean, wheat, peanut and cotton and other crops, control of eye vegetables, cattle grass, grass, wild Arrowhead, bitter grass, melon grass, water turtle, triangular grass, amaranth, amaranth, quinoa, Polygonum and other weeds. Such as the control of rice eye, 15~20 days after transplanting rice, when the eye is full of hair, leaves from red to green, with 25% wettable powder 15~22.5g/100 m2, 3kg of mixed fine fluvo-aquic soil is applied, or 7.5kg of water is sprayed. The water layer in field tank is 4-5cm when applied, and the water layer is maintained for 4-5 days after application, and then the field is allowed to fall to dry naturally. used as a pre-emergence herbicide, used to control annual weeds is a selective absorption conduction herbicide, mainly used in rice, can also be used in corn, soybean, wheat, peanut, cotton and so on selective internal absorption conduction herbicide, mainly used in rice field anti-weed, beef grass, eye vegetable, Alisma orientalis, wild Arrowhead, mother grass, Xiao Ci grass, etc., mixed with the grass, butachlor, can expand the weed spectrum, can also be used for corn, soybean, wheat, peanut, cotton and other herbicides. |
| production method | in the presence of sodium hydroxide, cyanuric chloride reacts with monoethylamine and sodium methyl mercaptan to prepare Xicao net. Raw material consumption quota: cyanuric chloride 1200kg/t, monoethylamine 660kg/t, sodium methyl mercaptan 550kg/t. under a certain pressure and the presence of sodium hydroxide, simazin and sodium methylmercaptan were reacted under reflux at 70-75 ℃ for 3H, cooled, crystallized, washed with water and dried to obtain Xiadao, and the solvent was recovered and treated. |
