Medication description

The drug includes a special active substance - tribenuron-methyl, which belongs to the chemical class of sulfonylurea. This component penetrates into plants through the root system and foliage, after which it begins to spread through them.

As a result of these processes, acetolactate synthase is blocked. This leads to suppression of the production of amino acids, which leads to a violation of mitosis and the synthesis of substances that are required for the formation of DNA. As a result, cell division slows down, which leads to the suppression of weed growth.

Composition

The drug belongs to selective herbicides. It is produced in the form of water-dispersible granules. The active ingredient of the drug is tribenuron-methyl. 1 liter contains 750 grams of active ingredient.

Means Benefits

The advantages of the drug include the following:
