Mode of action
Iodosulfuron-methyl sodium from the sulfonylurea class is an acetolactate synthase (ALS) inhibitor that acts on sensitive plants. It targets dicotyledonous weeds.
Florasulam from the triazolpyrimidine class also provides systemic action. They are mainly absorbed by the leaves of weeds and quickly move to the root system and stems, where they accumulate in growth points and exert a herbicidal effect. It inhibits acetolactate synthase (ALS), an enzyme involved in the biosynthesis of essential amino acids in the meristematic tissues of weeds.
Protective effect period
Against annual weeds — at least 25–30 days before the appearance of a new wave of seedlings. Against perennial weeds — throughout the entire growing season.
Rate of impact
Active growth of sensitive weeds stops within several hours after spraying the crops with the product. Yellowing of leaves of susceptible plants is noted for the first 3–5 days, after 7–14 days chlorotic spots are formed and growing points die off. Although the herbicide quickly penetrates into the leaves and roots of plants, complete die-off of weeds is noted 2–3 weeks after treatment of crops.
The most rapid herbicidal effect can be achieved by spraying weeds during early growth phases, as well as under favorable growth conditions (optimal humidity and temperature).
