Dear Customer: Hello! Thank you for your continued support for our company. The National Day is coming. In order to allow our employees to enjoy this important holiday, we will make the following adju...
Glufosinate-ammonium, also known as glufosinate, is a non-selective foliar spraying organophosphorus herbicide, which was first synthesized and developed by Hoechst Chemical Company in the Federal Republic of Germany in 1979. The herbicidal mechanism of glufosinate-ammonium is that after it is absorbed by leaves, it has a partial systemic effect, which can be transferred from the base of the leaves to the end, and less transferred to other parts of the plant, which is harmless to unearthed buds and seeds. Ammonium metabolism in plants is in disorder in a short period of time after application, and strong cytotoxic agent ammonium ions accumulate in plants; the plants are poisoned and die. At the same time, photosynthesis is also severely inhibited, and the affected plants turn yellow-white after chlorosis, and begin to wither and die after 2 to 5 days. Inactive after contact with soil, it should only be used for post-emergence stem and leaf spray.
Application: Glufosinate-ammonium is mainly used in orchards, vineyards, potato fields, nurseries, forests, pastures, ornamental shrubs and no-till land to kill weeds, and to control annual and perennial grass weeds, such as rhizome, wild oats, crabgrass , barnyardgrass, foxtail, bluegrass, creeping ice grass, bermudagrass, cutgrass, reed, fescue, etc. It can also control broad-leaved weeds such as quinoa, amaranth, polygonum, camelina, nightshade, chickweed, purslane, pigtail, endive, field thistle, field bindweed, dandelion, etc. There is also a certain effect. When the broadleaf grass is at the beginning of vigorous growth and the beginning of grass weeds, the dosage of 0.7 to 1.2 kg/ha is sprayed on the weed population, and the weed control period is 4 to 6 weeks. Extend the validity period. Potato fields should be applied before budding, or before harvesting, to kill stubble on the ground and facilitate harvesting. For the control of ferns, the dosage is 1.5 to 2 kg per hectare.
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.
