Expanded spectrum of action against dicotyledonous and grass weeds
Eradication of weeds from sprouting to early development phases
Long-term protection from repeated crop infestation
No phytotoxic effect on crops or restrictions on crop rotation
Working-in is not required
Propisochlor is mainly absorbed by the roots of seedlings. Effective against weeds during sprouting; has a weak effect on growing weeds. Inhibits meristematic cell division and protein and nucleic acid synthesis, which suppresses root growth, decreases osmotic potential and results in death of sprouts. Propisochlor effectively eradicates annual grass weeds as well as some broad-leaved weeds. Terbuthylazine has a systemic action. It is absorbed by the roots and leaves of weeds and moves acropetally via the xylem. The substance inhibits electron transport during photosynthesis, which leads to death of weeds. The herbicidal effect is observed for both germinating seeds and sprouts. Main spectrum of action: annual dicotyledonous weeds as well as some grass weeds
VERSIA, OD, combines two mechanisms of action and exhibits a synergistic effect of active ingredients, significantly broadening the spectrum of weeds eradicated (dicotyledonous and grass weeds), as well as the range of herbicidal effect (is effective against both germinating seeds and sprouts).
Protective effect period
A single application ensures the purity of seeds for 60–80 days (mainly throughout the growing period).
Rate of exposure
Weeds die several days after sprouting.
Spectrum of eradicated weeds
Annual grass and dicotyledonous weeds Highly susceptible species (95–100% eradication): barnyard grass, yellow foxtail, green foxtail, rough bristle grass, large crabgrass, annual meadow grass, etc. Susceptible species (85–95% eradication): common millet, witchgrass, Aleppo grass, Cuba grass (from seeds), black grass, amaranth (species), goosefoot, black nightshade, chamomile (species), little-flower quickweed, shepherd's purse, red dead-nettle, chickweed, common purslane, drug fumitory, potentilla (species), etc. Moderately susceptible species (75–85% eradication): trailing hollyhock, duck wheat, black bindweed Low susceptible species (60–75% eradication): common ragweed, lady's thumb, field mustard, butterweed

Pesticide application method
Prepare the working solution immediately before use. Prepare the stock solution in advance. Fill a separate container half full with water, add the required amount of the product for the stock solution concentration of 30–40% and mix for 1–2 minutes. Pour the resulting stock solution into the sprayer tank, filled three quarters full with water in advance. Flush the stock solution container with water several times and pour the water into the sprayer tank. Add water to the sprayer tank to the full volume and mix thoroughly.
Prepare the working solution and refill the sprayer at designated places that are to be deactivated later.
Use rod sprayers (Amazone, Lemken, Hardi, OPSh-15-01, OP-2000-2-01 or similar sprayers).
In soils with high humus content, the maximum dose of the product shall be used. Within 2‑3 weeks after treatment, inter-row cultivation is not recommended (in order not to compromise the protection).
Compatibility with other pesticides
Effective when used alone. If there is a need to use the product in tank mixtures, the components to be mixed should be checked for physical and chemical compatibility.
Transport and storage conditions
Comply with all conventional rules of toxic substance transport. Keep the preparation in a room dedicated for pesticide storage. Storage temperature range - minus 15⁰C to plus 35⁰C. Stir before use.
Shelf life
