HERBICIDE DEFENDA SHERIFF

Mechanism of Action

The active substance of the preparation – tribenuron methyl - by the method of action on the plant belongs to inhibitors of the synthesis of amino acids. Penetrating the plant through leaves, stems and roots, it is transported to growth points, blocks the production of basic amino acids and the division of plant cells. 2-3 hours after the sensitive plants of weeds have been treated with such the herbicide as SHERIFF, they are suspending in growth and development, stop absorbing water and minerals from the soil, and compete with cultivated plants. Visual signs of the preparation effect will appear 5-8 days later and manifest themselves in the rooting and death of plants. Young weeds are killed 2-3 days before the weeds of later stages of development.
