Furthermore, herbicides will provide little long-term control of weeds that have begun to flower and produce new seed. As annual weeds grow larger and mature, an herbicide’s effectiveness often decreases.
Therefore, you must also consider the weeds’ size and growth stage. Herbicide products often work best on younger, actively growing weeds. Tip 2: Apply at the right time of the year Many herbicides that are registered for use to control weeds in lawn or turf areas contain active ingredients that are not EPA-approved for application on pastures to be grazed by animals. It is also important to determine if an herbicide product is approved for application on grazed pasture fields.
Consult the product label and other resources such as university weed control guides (e.g., Weed Management in Grass Pastures, Hayfields, and Other Farmstead Sites, AGR-172 or Broadleaf Weeds of Kentucky Pastures, AGR-207) to determine if an herbicide will control the weeds of greatest concern. Most pasture herbicide products selectively target broadleaf weeds, but certain products are better for controlling specific weed species. It’s important to choose the right herbicide for the specific weed(s) you want to control. Furthermore, consider reseeding and a field’s future uses before applying an herbicide.īelow are some important tips to consider when choosing and applying an herbicide product. Stewardship includes proper spray applications to minimize the potential for off-site movement of herbicides that might damage nearby sensitive crops and vegetation. However, good stewardship and management practices are required to ensure you’re getting the most benefit from an herbicide application. Herbicides are one of the best ways to effectively control several troublesome broadleaf weeds.
These include mechanical and cultural practices such as mowing or clipping fields, maintaining a good soil fertility program, grazing methods, and other management practices that promote desirable forage grass growth, which in turn competes against weeds. Property owners can use various methods and strategies to combat weed problems in pastures.
