  2. If required add the correct amount of any dry formulation product.
  3. If required add the correct amount of grass control product.
  4. Add the required amount of Clobber.
  5. Add required amount of MPower® MPCA Ester.
  6. Add any required surfactants, complete filling of sprayer and apply.

UNDERSTANDING PERFORMANCE

  • Optimum results will be achieved between 15° C and 27° C in warm moist growing conditions when weeds are actively growing.
  • Canada thistle control will be reduced if weeds are larger than 10 cm and have already budded.
  • When weeds are stressed due to drought, flooding or prolonged hot or cool temperatures (less than 8° C or more than 24° C), control can be reduced or delayed since weeds are not actively growing. Weed escapes may occur under prolonged stress conditions or low fertility.
  • Do not make applications to weeds stressed longer than 20 days due to lack of moisture as unsatisfactory control can result.
  • Very dry soil conditions following application can result in a risk of injury to field peas, beans, clover, alfalfa or other legumes grown in rotation. Do not seed lentils on treated fields for at least 2 year
Always read and observe all label directions including rates, restrictions, and grazing and harvest limitations.
*Supported by AgraCity under PMRA tank mix guidelines. When applying tank mix combinations, read and observe all label directions for each product used in the tank mix, and follow the more stringent label precautionary measures for mixing, loading and applying stated on both product labels.
