Mode of action
In dry conditions, the product is absorbed by leaves. In wet soil, the product is also absorbed by roots, which strengthens its effect. The product inhibits the acetolactate synthase enzyme driving the synthesis of leucine, isoleucine, and valine amino acids, stops cell division in sprout and root growing points.
Protective effect period
Until the second wave of weeds.
Rate of exposure
In several hours after treatment, the growth of sensitive weeds ceases. Visible signs, such as anthocyanin color, chlorosis, and necrosis, appear only several days after treatment with weed death in 10 to 15 days.
Action spectrum
Annual dicotyledonous weeds.
Susceptible species: green amaranth, common caseweed, sunweed, day-nettle (spp.), stinging nettle, common nipplewort, chamomile (spp.), houndsberry, burnet rose, wild radish, knotted pepper plant, common persicaria, rape drop, sunflower drop, yellowweed, field mustard, bird's-eye speedwell, field scorpion grass, hemp nettle, dish mustard, butterweed, sow thistle species (sprouts), catchweed, annual mercury, barnyard grass.
Moderately susceptible species: copper rose, maple-leaved goosefoot, field pansy, knotweed, common ragweed.
Low susceptible species: orach (spp.), Canadian thistle, pigweed, woundwort (spp.), common fumitory, chickweed, black bindweed, winterweed, sheepbine, prostrate amaranth.
For optimal results and the fastest possible herbicide action:
- Treat weeds when they are in the seedling to two-leaf stage. Certain species, such as field mustard and sunflower volunteer plants, are fully controlled at the up to six-leaf stage. Treatment at later stages demonstrates reduced efficiency, and some species of weeds are rather suppressed than killed.
- Apply the product to crops during the growth stage from germination (70-90% emergence) until row closure.
- To broaden the spectrum of control, the product is commonly mixed with reduced doses of other herbicides for sugar beets.
- The ideal application temperature range is between 15 °C and 25 °C.
- At temperatures above 25 °C or below 10 °C for 3-5 hours, metabolism slows, which can cause temporary yellowish spotting on the leaves of treated crops. These symptoms do not appear on new leaves and typically disappear within 10 days, without impacting crop growth or yield.
-
Do not apply the product if the crops are affected by diseases, pests, or unfavorable weather conditions such as drought or frost.
