Broadleaf Weed Control Using Broadcast Applications Herbicide and Timing Recommendations | ANNUAL WEEDS Important Notes—Annual and Biennial Weeds Match herbicide rate with the growth stage of weeds and difficulty of control. Within the herbicide’s labeled range, increase the application rate as plants become more mature, when weed foliage is tall or dense or when growing conditions are less than favorable. Use enough spray volume. Recommended spray volume is 10 to 25 gallons per acre for ground broadcasts or 2 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. NOTE —The lowest cost feed you can buy is the extra grass you get from spraying weeds. As a rule of thumb, for every pound of weeds you control, you’ll get an extra pound of grass.
