Herbicide Glufosinate Ammonium CAS 77182-82-2

Glufosinate ammonium belongs to the phosphonic acid herbicide, partly systemic, non-conductive contact herbicide. Unlike glyphosate, which kills roots, glufosinate first kills leaves and conducts transmission in the xylem of plants through plant transpiration. Xylem is the transport organization of vascular plants and is responsible for transporting water absorbed by roots and ions dissolved in water. , For the use of other organs and tissues, and also has the role of supporting plants. High temperature, high humidity and high light intensity enhance the absorption of glufosinate ammonium and significantly increase the activity.

Solubility

It has low solubility in common organic solvents, and high solubility in water. It is hydrolyzed at pH 5-9, and the half-life in soil is <10d. Stable to light.

Control Object:

Used in orchards, vineyards, non-arable land, potato fields, etc. to prevent and control annual and perennial dicotyledons and gramineous weeds.

The weeding spectrum is wide. According to current information and data, many weeds are sensitive to glufosinate. These weeds include: goosegrass, bluegrass, sedge cyperus, bermudagrass, barnyard grass, ryegrass, bentgrass, cardamine sedge, alien sedge, crabgrass, wild licorice, fake smelly grass, corn Grass, Scaly-leafed Flower Grass, Flying Grass, Wild Amaranth, Seed Mai Niang, Alternanthera philoxeroides (Revolution Grass), Chrysanthemum, Little Scabies, Granny, Purslane, Brachiaria, Corydalis, Field Bindweed , Polygonum, shepherd's purse, sorrel, plantain, crowfoot, gypsophila, European Senecio etc.

Features

1. Glufosinate ammonium has strong penetrating ability and can prevent some glyphosate-resistant weeds, such as gooseweed, scabion, adenophora, etc.

2. Glufosinate ammonium has better properties. Its sex is between paraquat and glyphosate, and it usually has a significant poisoning reaction in 3 days.

3. Glufosinate ammonium has unique advantages in economic crops. This advantage stems from the superior control effect of glyphosate and its high safety. The use of glufosinate on bananas and papaya will not cause harm even if it hits the xylem.

4. Glufosinate ammonium can be widely used for spraying between rows of crops. Because it belongs to ammonium contact, it will not cause phytotoxicity as long as it is not sprayed directly on the crops. A small amount of floating liquid will only form spots at the contact points. Will not kill.
