Application Tips
For optimum results, apply to actively growing weeds. An early application will maximize crop yields by reducing
weed competition. Do not apply to crop that is stressed by conditions such as frost, low fertility, drought, flooding,
disease or insect damage as crop injury may result. Application before the 4-leaf stage may injure the crop.
