These herbicides are effective in controlling broadleaf weeds, grassy weeds, or both, depending on their mode of action. Selective herbicides are often used in pastures to target specific problematic weed species while preserving the growth of desirable forage species.

Non-Selective Herbicides: Non-selective herbicides are broad-spectrum herbicides that control all plant vegetation, including both weeds and desirable plants. These herbicides are useful when dealing with a wide range of weed species or when renovating a pasture and starting from scratch. However, caution must be exercised when applying non-selective herbicides in pastures to prevent damage to desirable forage species.

Systemic Herbicides: Systemic herbicides are absorbed by the weed and are transported throughout the plant, affecting multiple areas, including leaves, stems, and roots. These herbicides are effective at controlling established perennial weeds with extensive root systems. Systemic herbicides can provide long-lasting control by killing the weeds from the inside out.

Contact Herbicides: Contact herbicides kill the part of the weed that they come into direct contact with, usually the leaves and stems. These herbicides work quickly and provide rapid initial control. However, they may not have lasting effects on perennial weeds with extensive root systems. Contact herbicides are often used for spot treatments or controlling weeds in specific areas of the pasture.

Residual Herbicides: Residual herbicides are designed to stay active in the soil for a certain period, inhibiting weed seed germination or growth. These herbicides are particularly useful for preventing weed emergence over an extended period, providing long-term control. Residual herbicides are commonly used in pastures to minimize weed competition during key stages of forage crop development.

Pre-emergent Herbicides: Pre-emergent herbicides are applied before weed seeds germinate, forming a barrier that prevents weed growth. These herbicides work best when applied prior to weed seed germination, targeting the weed seeds in the soil. Pre-emergent herbicides are effective at reducing weed populations and preventing weed establishment.

Post-emergent Herbicides: Post-emergent herbicides are applied to actively growing weeds, targeting foliage and other plant parts. These herbicides work best when applied to young, actively growing weeds. Post-emergent herbicides provide control for existing weeds but may not prevent new weed seedlings from emerging.

Herbicide Resistance Management: It is important to be aware of any herbicide-resistant weed species in your area. Herbicide resistance occurs when certain weed populations develop the ability to survive and reproduce even after exposure to herbicides. To manage herbicide resistance, it is crucial to rotate herbicides with different modes of action, use tank mixtures of herbicides with multiple modes of action, and implement integrated weed management practices.
