Important notes or exceptions
1.
Apply when chickweed is small (1-6 leaf) and actively growing, but before canopy prevents thorough herbicide coverage of weeds.
2.
Apply when the majority of thistles have emerged and are actively growing. For best top growth control, apply before bud stage when thistles are no
larger than 15 cm in height. A single application will effectively inhibit the ability of emerged thistles to compete with the crop.
3.
If the product is used without a wild oat herbicide, add a non-ionic surfactant such as Ag-Surf at a rate of .2% v/v (2L/1000 L of spray solution).
