Mechanism of action
The active ingredient suppresses acetolactate synthase enzyme and stops cell division in sprout and root growing points of sensitive weeds. It is absorbed mainly by leaves, and its efficiency is not therefore dependent on moisture content in soil.
Protective period
The bio-effect lasts throughout the vegetation period.
Speed of action
In several hours after exposure, sensitive weeds cease growing and no longer compete with crop plant for moisture and mineral absorption. Other visible symptoms (reddening, chlorosis, necrosis, and leaf deformation) appear in 2 or 3 days after treatment, and sensitive weeds die totally in 5 to 15 days.
Spectrum of action
Annual and perennial cereal and bilobate weeds.
Sensitive species: ragweed, quack grass, Aleppo grass, common orach, loose silky bent, rough-stalked bluegrass, barnyard grass, foxtail (species), crabgrass, sorgho, oat grass, ryegrass, velvetleaf, amaranth (species), pigweed (species), wild radish, caseweed, common fumitory, catch weed, chamomile (species), charlock, spring groundsel, sow thistle (species), sheep bur, vetch, satin, foxtail, copper rose, tufted vetch, hemp nettle (species), woundwort (species), dish mustard, day-nettle.
Moderately sensitive species: Canadian thistle, sheepbine, bladder campion, prickly lettuce, pepper plant (species), field pansy.
Feebly sensitive species: tansy mustard, jimsonweed, houndsberry, blue couch grass.
Compatibility
Efficient when used alone. It may be commingled with 2,4-D based preparations for maize treatment, or Zontran, CSC for potato treatment. When combining in mixes, perform trial mixing. Where physical and chemical properties change, avoid combined use.
Potential for resistance
Where recommended doses and preparation application technique are met, resistance is unlikely to occur.
