Clopyralid (as 2-ethylhexyl ester) 100 g/l + fluroxypyr 15 g/l

Postemergence herbicide of systemic effect intended to control annual and perennial bilobate weeds on rape plantings.

General information


  • highly effective at reduced concentration of the active ingredient due to innovative preparative form CSC;
  • efficient control of catch weed and corn bindweed;
  • fast penetration and high bio-efficiency due to unique preparative form;
  • wide range of application timing;
  • elaborate combination of two active ingredients complementing each other prevents the occurrence of weed resistance.

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.

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 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.
Use ground-based beam sprayers Amazone, OPSh-15-01, OPSh-3-24, ON-400, OP-2000-2-01, or similar.
No cases of phytotoxicity to crops were recorded when recommendations on preparation application timing and rates were met. No adverse effect of the herbicide on growth and development of crops treated was recorded.
