Let’s grab some weed & feed for your pastures, friend. Summer’s heat has your grazing grounds growing weeds faster than your cattle can mow the grass. But have no fear – with the right know-how, you’ll keep your fields fit for livestock in no time.

Though tempting, holding off until autumn leaves you losing the weed war. Early summer’s prime time to act while weeds are young and less hardy against herbicide. Consult your local extension office to ID specific species, then choose systemic herbicides to knock ’em out at the roots.

With a custom spray plan in hand, you’ll keep your pasture – and profits – growing strong. So scout your acreage, map problem areas, and take aim at weeds now before they take over.

Healthy grass makes healthy cattle and a healthy bottom line.

Weed Identification and Herbicide Selection

You’ll want to inventory your pastures in early fall and adjust grazing pressure. Identify target weeds and match herbicide selection and application timing to the species and growth stages present. Walk through each pasture and note weed density, problematic areas, and evaluate overall forage stand density.

Adjust livestock pressure to avoid overgrazed areas where weeds thrive. Identify key weeds and determine if they are annual, biennial, or perennial in order to select the proper herbicide. Read labels thoroughly, choosing products labeled for the target weeds and registered for use in pasture.

Match herbicide rates to weed size and growth stage. Select the right product and time the application to weed growth for effective control.

Common Toxic and Noxious Weeds

Watch out for those pesky jimsonweeds, thistles ‘n such when ya mosey through the pasture, or your cattle could get mighty ornery after snackin’ on ’em.

Keep an eye peeled for poison hemlock’s ferny leaves and purple blotches.

Scout early for multiflora rose, now a certified noxious weed in many states.

Pigweeds like Palmer amaranth can quickly take over an under-grazed pasture.

Proper identification is crucial to control those bad boys before they spread their toxic seeds all over the place.

And don’t forget to walk the fence lines where pesky thistles and such like to hunker down.

Keepin’ up with those sneaky weeds takes some know-how and elbow grease, but payoff is healthier, happier cattle and pastures.

Forage Crops Herbicides Application

When selecting herbicides for pastures, match the product’s timing, rate, and spectrum to target weeds at their most susceptible growth stage. Know weed lifecycles and their timing of emergence. Time applications for during or just prior to weed seed germination.

Assess weed growth stages and spray weeds when small and actively growing. Tank-mix herbicides with different modes of action for broader spectrum control. Spot spray weeds using a handheld sprayer. Promote dense forage stands through fertility, proper cutting height, and stand renovation.

Time herbicide applications to avoid crop injury. Consider herbicide persistence and rotational restrictions. Implement cultural practices first, then use herbicides judiciously as needed for effective integrated weed management.

Identify the Weeds

Before choosing an herbicide, carefully identify the specific weeds infesting your pastures so you can select the right product and application timing.

1. Walk your pastures in early spring, late winter, and mid-summer to make a list of all weed species present.
2. Note aggressive weeds like broadleaf plantain, musk thistle, multiflora rose, curly dock, and purple loosestrife.
3. Differentiate annual, biennial, and perennial weeds since their life cycles dictate control timing.
4. Consider pre-emergent herbicides for early spring weeds; avoid summer spraying of perennials.
5. Rotate grazing animals before seedheads emerge to prevent spreading.

Knowing the weed species on your land allows matching the herbicide mode of action and application timing to target them most effectively. Proper identification and a customized plan are key for optimal pasture weed management.

Seasonal Applications

You’ll wanna target those rascally biennials in autumn once their leaves emerge and the weather’s still warm enough for the herbicides to be absorbed, lest those buggers go to seed come spring.

The ideal time for pasture spraying depends on the types of weeds present and their growth stages.

Weed Type	Optimal Spray Window
Annuals	Early spring or fall when small
Biennials	Fall rosette stage before winter
Perennials	Early fall with active growth

When selecting herbicides, match timing to the product’s strength on your weed targets. Consult labels for specifics on growth stages, adjuvants, rates, and grazing restrictions.

With a bit of planning and proper execution, you’ll keep those pesky weeds at bay and your pastures prancing.

Can You Spray Pasture for Weeds in Summer?

During the summer months, herbicide application on pasture forages requires careful consideration of growth stage and environmental conditions to achieve efficacy. Target spot spraying, rather than broadcast application, can help minimize herbicide usage while controlling key weed species.

Careful observation, timing, and selective herbicide use let summer spraying strengthen pasture quality and productivity while following label guidelines.

Applying Herbicide

You’ve made great progress controlling summer weeds. Now, focus on applying herbicide at the optimal time for your target weeds. Regularly scout pastures, estimate weed densities, and assess previous control efforts.

This helps determine timing and herbicide selection. Match application timing and herbicide mode of action to the weed growth stage for best results. Adjust applications based on scouting. With a plan targeting problem weeds, you’ll gain control.

Rotate Your Grazing Animals

Rotate your grazing animals.

Rotating your grazing animals helps reduce pressure on any one area, allowing pasture plants to recover and outcompete weeds. By moving livestock between paddocks and avoiding overgrazing, you give your forages a rest period to regrow thicker and crowd out opportunistic weeds.

This also prevents selective grazing, where animals repeatedly graze preferred plants while ignoring weeds. Work grazing rotations so each paddock has adequate recovery before animals return. Moving animals when weeds are still small interrupts seed production and the lifecycle of persistent pests like thistles.

Rest also supports root growth for drought tolerance. Adjusting grazing pressure along with other practices like fertility management, timely mowing, and renovating thin stands delivers integrated control that minimizes reliance on herbicides.

With a little planning, you can leverage grazing patterns and promote healthy, weed-resistant pastures.
