Broadcast Applications on Brush
The following table gives you a list of several choices available to control certain species. The cost and degree of control offered by the different tank mixes will vary, so it’s important to talk with your Corteva Agriscience ™ representative before you decide. Notes For brush densities of more than 200-300 plants per acre, broadcast applications usually will be more cost-effective than individual plant treatments.
Important Tips 1. Read and follow all label directions and restrictions. 2. Properly calibrate equipment.
3. Use enough spray volume. Recommended spray volume is 10 to 25 gallons per acre ground broadcast or 4 to 5 gallons per acre by air. Higher spray volumes in the range generally provide better coverage and better control. Use the recommended rate of an agricultural surfactant, plus a drift control agent where needed. 4. Apply herbicides when environmental conditions are as close to optimum as possible. Use the recommended rate of an agricultural surfactant, plus drift control agent where needed. Do not apply with liquid fertilizer. Consult your local Natural Resource Conservation Service office, County Extension Agent or a Corteva Agriscience representative for more details concerning proper timing. 5. For woody species, make sure the target plant has good foliage. Insects, hail, freezing weather or drought may damage plant foliage reducing your degree of control. 6. For Macartney rose, multiple treatments may be needed for control. Broadcast Brush Applications Brush Species • Herbicide • Product Per Acre • Time to Treat
