Action

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.

Application technique. Mix preparation method
Prepare the mix immediately before use. Dose the herbicide for a single fill of the sprayer. To prepare the stock solution, fill the vessel (bucket, tank) with water to 1/4, add the herbicide dose, stir uniform liquid and top up with water to 3/4. The fill the sprayer tank with water to 1/2, add the prepared stock solution of herbicide, add the surfactant to the mix, fill the tank with water until full while continuously stirring the mix with hydraulic agitators. Then rinse several times the vessel where the stock solution was prepared. During spraying, the hydraulic agitator of the sprayer shall be in operation. Use the prepared mix immediately after preparation. After treatment with the herbicide, thoroughly rinse the sprayer tank with water and soda ash.
Prepare the mix and fill the sprayer on dedicated sites that are disinfected afterwards.
Use ground-based beam sprayers OPSh-15-01, OPSh-3-24, ON-400, OP-2000-2-01, or similar.
The best result and quickest herbicide action of the preparation are achieved by:

  • crop treatment in the most favorable weather conditions: optimal air humidity and temperature of 15⁰C to 25⁰C.
  • Do not use when plants are wet after rain or dew.

Phytotoxicity
The preparation does not pose phytotoxic effect on crops protected when used in recommended doses.

Recommendations on protection of valuable flora and fauna objects
The preparation is of low hazard to bees – Hazard Class 3, and virtually of no hazard to fish – Hazard Class 4.
Basic provisions of the ‘Guidelines for preventing bee poisoning with pesticides’ and following environmental regulations:
treat plants in morning and evening;
treat plants at wind speed up to 4 or 5 m/sec;
protection boundary zone for bees – 2-3 km;
bee’s flight time limitation – 3-4 hours.
Warn apiary owners 4 or 5 days before treatment.
Do not use the preparation in private farms and by aerial method.
