- Highly effective at reduced concentration of the active ingredient due to innovative formulation OD;
- Ideal combination of active ingredients;
- Most extended spectrum of action on weeds at soybean plantings;
- Prolonged protective period:
- Exposure on weeds through leaves and roots;
- Soil herbicidal activity.
Mechanism of action
The preparation penetrates leaves of weeds and quickly moves towards roots and stalks. In several hours, cell division in sensitive species of weeds and their growth stops. The formulation of oil dispersion increases wetting and absorbing capacities and improves penetration of active ingredients.
Useful to control bilobate and cereal weeds throughout the vegetation period. Affects weeds already emerged and sprouting during treatment virtually throughout the entire crop vegetation period.
Speed of action
Sensitive weeds cease growing in several hours after treatment. The herbicide is quickly absorbed by leaves and moves along the entire plant, however complete perishing of weeds is observed in 2 or 3 weeks after treatment. How fast the signs of delayed growth appear depends on weather conditions during treatment (humidity, temperature), species composition of weeds and their growth stage. Young weeds are more sensitive to the herbicide. Leaves of sensitive weeds become chlorotic in 1 to 3 weeks after treatment, and the growing point perishes.
Range of inhibited weeds
Annual bilobate and cereal weeds.
Sensitive species: ragweed, pepper plant (species), charlock, jimsonweed, sheep bur (species), common fumitory, satin flower, velvetleaf, common orach, copper rose, pigweed, field oat grass field, catch weed, common purslane, barnyard grass, wild radish, violet (species), horehound, foxtail (species), amaranth (species), etc.
Compatibility with other pesticides
Crop rotation limitations shall be observed after using Concept, OD herbicide considering its potential aftereffects.
When re-sowing during the year of application, winter wheat shall be sown. Next year, spring and winter cereals may be sown, and in 2 years all crops without limitations.

Application technique. Mix preparation method
Prepare the mix immediately before use. Fill the sprayer tank with water to 3/4 of its volume, slowly add the entire preparation dose while stirring, and rinse the preparation remainders several times with water. Pour water after rinsing the preparation vessel to the sprayer tank and top up with water until full while continuously stirring.
Prepare the mix and fill the sprayer on dedicated sites that are disinfected afterwards.
Commercially available ground-based boom sprayers intended for herbicide application shall be used for treatment purposes.
The best result and quickest herbicide action of the preparation are achieved by:
- Treatment at ambient temperature of 10⁰C to 25⁰C with optimal temperature over 15⁰C.
- Do not treat soybean plantings that are under stress due to low ambient temperature (cooling to 6⁰C), heat, drought, mechanical damage, attack by pests and diseases.
- Planting spraying at earlier stages of weed growth. If overgrown (more than 4-6 leaves), weeds sensitive to the herbicide become more resistant.
- To maintain ‘herbicide’ screen and to extend soil action, avoid mechanical treatment of plantings during three weeks after herbicide application.
The preparation is not phytotoxic to soybeans if used in line with the regulations. However, in specific cases, maximum herbicide dose may cause short-term discoloration of leaves exposed. Such damage vanishes with time and is not manifested on new soybean leaves.
In most experiments, removal of competitive weeds increased soybean yield dramatically.
Potential for resistance
In case of long-term use, biotypes of weeds may appear that are resistant to sulfonylurea and imidazolinone herbicides. To avoid this, herbicides from various chemical groups with different mechanisms of action shall be alternated.
Keep the preparation in a room dedicated for pesticide storage. Storage temperature range - minus 10⁰C to plus 35⁰C. Stir before use.
