Replaces urea systemic herbicides. Chemical name: 3-(3,4-dichlorophenyl)-1,1-dimethylurea. The chemical structural formula is as follows. The pure product is white odorless crystal, the melting point is 158～159℃, and the vapor pressure is 413.3×10-6Pa at 50℃. Almost insoluble in water, low solubility in hydrocarbons, increased solubility in hot organic solvents. It is stable to oxidation and humidity, stable under normal temperature and neutral conditions, and accelerated by heating and hydrolysis under strong acidic or alkaline conditions. Diuron has a certain contact killing activity and can be absorbed by the roots and leaves of plants, mainly absorbed by the roots. After the plant absorbs the chemical, it is transmitted to the plant leaves with the transpiration flow, which inhibits the Hill reaction of photosynthesis, causing the leaves to lose green, and the leaf tips and leaf margins to fade, and then turn yellow and die. Diuron can be used as a selective herbicide at low doses and as a biocide at high doses. Diuron is suitable for use in rice, cotton, corn, sugarcane and fruit, gum, mulberry and tea gardens to control barnyardgrass, crabgrass, foxtail, polygonum, quinoa and quinoa. It has low toxicity to humans and animals. The LD50 of acute oral administration in rats is 3 400 mg/kg. At high concentrations, it is irritating to eyes and mucous membranes.
Glyphosate is a non-selective and no residual sterilant herbicide which has a high effect on the perennial weed killing. It is widely used for the weed control and killing in corn plants, beans plants, tea, and other fruits plant trees, etc.
Herbicide Tribenuron-methyl 75% WDG, 60%DF, super high effect, pesticide agrochemical (Tribenuron methyl 95%TC, technical material available also)
It's widely Used for controlling broad-leaved annual and perennial weeds and sedges in rice fields, direct seeding fields and transplanting fields
Bensulfuron-Methyl is suitable for controlling paddy a year and perennial broadleaf weeds and sedges.
Systemic herbicide absorbed principally by the roots, with translocation acropetally in the xylem.
Glyphosate (N-(phosphonomethyl)glycine) is a broad-spectrum systemic herbicide and crop desiccant.
Metribuzin Uses Pre- and post-emergence control of many grasses and broad-leaved weeds in soya beans, potatoes, tomatoes.
Metsulfuron methyl applied mainly in wheat, barley, oat,etc.to control most broad-leaf weeds and certain grasses,by either.
