Take you to know the application skills of glufosinate
Glufosinate is a broad-spectrum contact herbicide . The systemic action is not strong. Unlike glyphosate root killing, glufosinate first kills leaves. It can be transported in the xylem of plants through plant transpiration. Its quick-acting effect is between paraquat. Between glyphosate. The pesticide network Xiaobian introduces the application technology of glufosinate.

Glufosinate 1, herbicidal spectrum According to current data and data, many weeds are sensitive to glufosinate. These weeds include: goosegrass, bluegrass, sedge, berm, valerian, ryegrass, bentgrass, broken sedge, shaped sedge, crabgrass, wild licorice, fake stink grass, corn Grass, rough leaves, flowers, flying grass, wild leeks, looking Mai Niang, Alternanthera philoxeroides (revolution grass), luxuriant, small flying poncho, mother-in-law, purslane, four-armed grass, sable, snail , cellar, leeks, chicory, plantain, buttercup, gypsophila, senecio, etc.
2, the characteristics of the action of glufosinate after spraying for 6 hours without rain, in order to maximize its efficacy; in the field conditions, due to soil microbial degradation, the roots can not absorb or absorb very little, after stem and leaf treatment The leaves rapidly produce phytotoxicity, thereby limiting the conduction of glufosinate to the phloem and xylem. High temperature, high humidity and high light intensity enhance the absorption of glufosinate and significantly increase the activity. The pesticide manufacturer reminds everyone that the addition of 5% (W/V) ammonium sulfate to the spray solution can promote the absorption of glufosinate and effectively increase the glufosinate in low temperature conditions. Under activity. The sensitivity of a series of plants to glufosinate is related to the absorption of herbicides, so ammonium sulfate has a more pronounced effect on the weeds with low sensitivity.
3, environmental safety glufosinate is rapidly degraded by microorganisms in the soil, leaching in most soils no more than 15 cm, soil effective water affects its adsorption and degradation, and finally releases carbon dioxide. No residue was detected at the time of crop harvest and the half-life was 3 to 7 days. 32 days after stem and leaf treatment, about 10% to 20% of the compound and degradation products stayed in the soil until 295 days, and the residual level was close to zero. From environmental safety considerations, short half-life and poor mobility in the soil make glufosinate suitable for weeding in forests.
4. Other characteristics Because glufosinate has a wide spectrum of herbicides, rapid biodegradation in the environment and low toxicity to non-target organisms, it is of great significance to use it as a selective herbicide for crop field seedlings, and bioengineering technology is This provides the possibility. At present, glufosinate is second only to glyphosate in the research and promotion of transgenic herbicide-tolerant crops. Currently, glyphosate resistant to glufosinate has rapeseed, corn, soybean, cotton, sugar beet, rice, Barley, wheat, rye, potato, rice, etc. There is no doubt that glufosinate has a huge commercial market.
According to the Pesticide Information Network , glufosinate can effectively control the infection of rice sheath blight and reduce the colonies it produces. It has high activity against fungi causing sheath blight, sclerotinia and Pythium blight. At the same time, weeds and fungal diseases of glufosinate-resistant transgenic crops are controlled. Spraying a normal amount of glufosinate in the glufosinate-resistant transgenic soybean field can effectively inhibit the soybean bacterial pathogen Pseudomonas, which can inhibit or delay the growth of bacteria.
