Mode of action
A systemic herbicide, which is mainly absorbed by the leaves of weeds and quickly moves to the root system and the stems, where it concentrates in the growing-points and exerts a herbicidal effect. At the biochemical level, the mechanism of action is to block the acetolactate synthase (ALS) enzyme, which is involved in the biosynthesis of essential amino acids in the weed meristematic tissues. This causes cessation of protein synthesis and stops cell division, which leads to the death of weeds.
Period of protective effect
Depending on the species composition of weeds, the soil and climatic and weather conditions, the period of protective action is up to 8-10 weeks after the application of the herbicide.
Rate of exposure
The active growth of sensitive weeds and competition with the crop halt within a few hours after treatment. Visible symptoms, such as halt of growth, chlorosis, dying of growth points and necrosis, appear after 2-3 days. The death of sensitive weeds occurs in 10-20 days. Weeds that are in the late developmental stages during spraying stop their growth, which significantly weakens their potential to compete with the crop.
