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...
Degradation and Residue
Glufosinate-ammonium can be rapidly degraded in soil by microbial degradation, producing 3-(methylphosphorylidene)propionic acid (MPP) and 2-(methylphosphorylidene)acetic acid (MPA) and releasing carbon dioxide. The leaching in most soils does not exceed 15 cm, and the soil available water content and soil oxygen content have a certain influence on the adsorption and degradation of glufosinate-ammonium. The degradation half-life (DT50) of glufosinate-ammonium is 4-10 days.
impact on soil
Glufosinate-ammonium can have a certain effect on some microorganisms in the soil. Different concentrations (0, 2, 4, 6, 8L/hm2) of glufosinate-ammonium on the number of soil microorganisms (bacteria, actinomycetes, fungi) and soil enzymes (catalase, phosphatase, urease, dehydrogenase) in wheat fields ) activity showed a trend of increasing first and then decreasing. When the application rate of glufosinate-ammonium was 6L/hm2, the total amount of microorganisms reached the highest. Among them, the number of bacteria and actinomycetes increased compared with the control, while the number of fungi did not change significantly. Under the low concentration (2, 4 and 6L/hm2) glufosinate-ammonium treatments, the tested soil enzyme activities all increased with the increase of glufosinate application rate, while under the high concentration (8L/hm2) glufosinate-ammonium treatment The enzymatic activity was inhibited.
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.
