Mode of action
Tifensulfuron-methyl, flumetsulam, and florasulam are systemic compounds. They are mainly absorbed by the leaves of weeds and quickly move to the root system and the stems, where they concentrate in the growing-points and exert 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.
The total synergistic effect of the three active substances maximizes the herbicidal activity of the product in relation to the widest spectrum of dicotyledonous weeds.
Period of protective effect
Throughout the growing period (depending on the weather conditions and in the absence of a new weed "wave").
Rate of exposure
The active growth of sensitive weeds and competition with the crop halt within a few hours after treatment. The first visible symptoms of weed depression appear 2-5 days after application, and their final death occurs 2-4 weeks after treatment and depends on the species composition and the developmental phase of weeds, the degree of contamination, and climatic conditions before, during, and after spraying.
