Mechanism of action
Clopyralid has an auxin type systemic effect. It is absorbed by leaves and roots, easily moves along plants and accumulates in the growing point and roots. Fluroxypyr is quickly absorbed by weed leaves and partially by plant roots from soil. It actively moves and spreads along the entire plant, including growing points. By the principle of action, fluroxypyr is similar to a natural hormone - indolyl acetic acid. It causes unbalance of growth hormones in weed meristems. Oversaturation of meristem cells with synthetic hormone results in impairment of cell division and growth.
Protective period
Protects the crop against weeds throughout the vegetation period.
Speed of action
Sensitive weeds cease growing in 2 hours after preparation application. Visible signs of exposure (growth arrest, leaf and stalk deformations) appear in 2 to 5 days after herbicide application, and total extinction takes place in 2 or 3 weeks depending on kind of weeds and weather conditions. The best result is achieved when treating young, actively growing weeds.
Range of inhibited weeds
Annual and perennial bilobate weeds, including catch weed and corn bindweed.
Compatibility with other pesticides
The preparation may be used in mixes with herbicides and insecticides provided the registered usage regulations are met and their application times coincide.
Hazard class
Hazard class III, moderate hazard.
Potential for resistance
To avoid resistance of weeds, alternate the preparation with herbicides of other chemical classes.
