Landowners should use a number of approaches and techniques to tackle weed issues in pastures. These involve mechanical and cultural methods such as mowing/clipping fields, keeping a consistent soil fertility program, grazing methods and other management practices that encourage favorable grass forage growth while acting against weeds.Herbicides with chemicals are one of the easiest approaches to successfully manage a variety of problematic broadleaf weeds. Nevertheless, proper stewardship and management techniques are required to ensure that you profit best from the usage of herbicides.

Stewardship requires sufficient spraying applications to mitigate the risk for off-site transport of herbicides that could threaten surrounding sensitive crops, plants and animals. In addition, consider reseeding and potential usage of the field prior to the use of the herbicide.

Regulation of weeds in pastures can be a very challenging problem. Plant types are special to livestock grazing schemes. Focus on the plants that animals stop consuming and others of poor nutritional value. Effective weed control requires the dedication and usage of a variety of weed control techniques.

Below the experts offer a few powerful solutions for chemical weed control on pastures. Check the comparison table and individual review of each herbicide for pastures to make a decision on what suits your demands. The buying guide includes some useful tips as well.

The Buyer’s Guide

Active ingredients

The active component is the concept that describes the chemical in the formulation of the herbicide specifically liable for its phytotoxicity (meaning it can weaken or kill plants). Such herbicides only produce one active component, whereas others contain two or three components: 

  • 2,4-D is marketed under a range of trade names, and dicamba is generally sold as Banvel or Transparency. Reasonable utilization rates are dependent on a variety of variables, including forage species and age, weed species current, weed growth habit, weed growth stage, the season of application, over-seeding, grazing or harvesting;
  • Aminopyralid is a selective weed killer used for the control of broadleaf weeds, particularly thistles and cloves. It is included in the herbicide class of picolinic acids, which also contains clopyralid, picloram, triclopyr and other less popular herbicides;
  • Triclopyr is a weed killer applied to manage woody plants and certain broadleaf weeds, including right-of-way, agricultural fields, plantations, railroads, meadows, grassland and permanent grass pastures, corn, turf and planting crops such as palm oil. Triclopyr collects in the meristematic tissue (growing region) of the plant. Triclopyr is prepared as soluble, emulsifiable concentrates, pigments, pellets, granules and liquids;

The application timing

Herbicide chemicals also perform well on younger, actively developing weeds. Therefore, you must also note the scale of the weeds and the level of development. As annual weeds develop greater and mature, the potency of herbicides also declines. In comparison, herbicides can have no long-term protection of weeds that have started to bloom and grow new plants.

Target the cool-season weeds, such as buttercup, biannual thistles, and poisonous hemlock, after they begin to appear in the fall (October-November) or the early spring (March-April). Treat annual summer weeds, such as common ragweed, and cocklebur, spiny amaranth, with an herbicide for pastures in early summer (June) when these plants begin to appear as seedlings.

The preferred time for the control of such perennial broadleaf weeds as tall iron weeds, curly dock, Canada thistle is summertime (August-early September). Mid-summer mowing with the proper herbicide treatment performs great with annual weeds such as high iron weeds. Late summer applications can often result in more movements of herbicides to the root systems of annual plants on pastures.

The volume

Another practice for creating bigger droplets is the usage of spray tips for spraying amounts of 15 or more gallons of fresh water per acre handled. But resist increasing spray intensity to reach higher spray concentrations, which may, in fact, result in finer droplets for certain spray tips.


A few horse owners confirmed that the horses that lick Roundup might get colic. For 2,4 D, there are no limits on pasture horses, so you can spray while plants are vigorously developing (not during the hot season), using 4 quarts per acre of spray or 2 ounces per 1 gallon of spot spray.

Delicate non-target plants, such as other seeds, grasses, ornamentals, and trees, can be significantly harmed or destroyed if herbicides are permitted to come into contact with their leaves, branches, roots, or soil in their rooting areas. Damaged non-target plants can trigger aesthetic or financial damage. Non-target plant damage is often induced by pesticide drift or straight application to vulnerable plant sections.

Waiting period

Any herbicides have a necessary waiting time between application of the herbicide and corresponding grazing or harvesting (grazing and harvest restrictions). The amount of time focuses on the herbicides and the livestock eaten or grazed. You must wait for the most stringent herbicide to be used.

An optional rule of thumb is to wait for the appropriate period and restart grazing or harvesting operations only if half an inch or more of the rainfall has accrued after the submission. Otherwise, wait for a half inch of rainfall precipitation before grazing or harvesting starts. Consult the herbicide manufacturer or the qualified expert for applications.

Check the labels

Until using a herbicide, read the label cautiously. Any of the herbicides prescribed has the advantages and risks correlated with its application. Apply the remedy to perennial weed at the particular growth stage(s) listed on the label.


How much herbicide do you need to mix with water to cover one acre?

The amount of herbicide you need will vary depending on the type of grass and weeds you have. For most products, you will mix two to four ounces of herbicide per gallon of water. One gallon of mixed solution will cover approximately one acre.

Weed types will also affect how much herbicide you need. Broadleaf weeds are generally larger and easier to control than grassy weeds. As a result, you may need less herbicide for broadleaf weeds.

Are there any negative aspects to using herbicides on pastures?

The main downside of using herbicides is the potential for negative impacts on the environment. When used incorrectly, herbicides can pollute water sources and kill helpful plants and animals. Another concern is the possibility of developing resistance in target weeds. Over time, weeds may evolve to become resistant to a particular herbicide, making it less effective. Finally, some people are concerned about the health risks associated with exposure to herbicides. While most products are considered safe when used as directed, some people may experience skin irritation or other side effects.

Before using any herbicide, it’s important to read the label carefully and follow all directions. Pay special attention to warnings and precautions to help minimize any risks. If you have any concerns about using herbicides, talk to your local extension agent or other agricultural expert. They can offer helpful advice and guidance on choosing and using products safely.

When used properly, herbicides can be a valuable tool for managing pastureland. By working to control weeds, they can help improve forage quality and quantity, which can benefit both grazing animals and farmers. When used in combination with other management practices like mowing and grazing rotation, herbicides can play an important role in maintaining healthy pastures.
