Tribenuron-methyl

This product is a selective, internal and chemical herbicide. It can be absorbed by the roots and leaves of weeds and transmitted in plants. Biosynthesis of branched chain amino acids (such as leucine, isoleucine, valine, etc.) is affected by inhibiting the activity of ALS. The plant suffered from growth spot necrosis and green chlorosis, and the plant growth was severely inhibited and dwarfed, and finally the whole plant died. The sensitive weed stopped growing immediately after its absorption, and died 1-3 weeks later.

Glyphosate

Glyphosate is an internal transmission type, broad-spectrum herbicide with low toxicity. Glyphosate within strong systemic conductibility is known, it can not only through the stems and leaves of conduction to the underground part, but also can be conducted in different tillers of the same plant, the underground deep roots of perennial weed damage is very strong, can achieve the general agricultural machinery can not reach the depth. There are 40 families of plants of glyphosate on controlling effects, including monocotyledonous and dicotyledonous, annual and perennial herbs and shrubs, and other plants, but not for soil treatment. Glyphosate soon loses its activity after being buried, and has no adverse effects on the underlying seeds and soil microorganisms in the soil.

atrazine

This product is a selective, pre - and post - seedling closed herbicide. Root absorption was dominant and stems and leaves were seldom absorbed. It is easy to be leached to deeper soil by rain water. It is also effective for some deep roots, but it is easy to cause phytotoxicity. Longer duration of efficacy. It can kill many kinds of annuals, grasses and broadleaf weeds.

Oxyfluorfen

Selective pre - or post harvest herbicides. It was a contact killing herbicide. Exert its herbicidal activity in the presence of light. Mainly through the coleoptile and hypocotyl into the plant, less absorbed by the roots, and a very small amount of transport through the roots into the leaves.
