Introduction

Postemergence - Leaf stage of the weeds is critical for good weed control. Smaller weeds are generally easier to kill but there needs to be enough leaf surface to intercept the herbicide. Apply according to recommended leaf stages. Always use appropriate drift management technology.

• Apply to young, actively growing weeds when temperatures are above 15°C.
• Complete coverage is necessary to achieve control.
• Use the low rate for annual weeds that are small (3 to 5 leaf).
• Ude the high rate for larger annual weeds and perennial weeds.
• Weeds that are near maturity, flowering, dormant or hardened due to drought or temperature stress are more tolerant to EcoClear treatments and may not be adequately controlled with a single application.
• A repeat application is effective for extended control of perennial weeds following initial burn down.
• Avoid application to reactive metals.
