Maintaining a vineyard requires precise and effective weed control to ensure that grapevines thrive without competition. The right herbicide helps reduce labor, manage invasive species, and maintain a clean environment for optimal vine health.

Choosing a vineyard-safe herbicide ensures the safety of crops while controlling weeds efficiently. Whether you’re managing a small boutique vineyard or a large commercial operation, selecting the correct herbicide is vital.

Key factors include selectivity, residual activity, rainfastness, and application flexibility.

This guide covers the top-rated herbicides tailored specifically for vineyards.Below are 10 of the best herbicides for vineyards,. Let’s explore the options.

Top 10 Herbicides for Vineyards

1. Chateau Herbicide

Chateau Herbicide is a pre-emergent herbicide widely used in vineyards for its long-lasting weed suppression. It controls broadleaf and grassy weeds, offering up to eight months of residual control. Its active ingredient, flumioxazin, binds to the soil and prevents weed germination.

Chateau is rainfast within hours and works best when applied to moist soil. It must be activated by light irrigation or rainfall to enter the root zone. Use it in dormant vineyards to avoid vine contact during application.

Growers favor it for low soil mobility and strong pre-emergent action. It helps reduce post-emergent herbicide use and labor. Safety gear is required when applying.

2. Roundup PowerMAX

Roundup PowerMAX is a non-selective, post-emergent herbicide that quickly kills most weed species on contact. It contains glyphosate, which inhibits enzymes essential for plant growth. This formula is rainfast in 30 minutes and ideal for targeted vineyard row applications.

When used with shielding, it effectively manages weeds without harming grapevines. Apply during calm weather to prevent drift. It is one of the most widely used herbicides due to its quick knockdown and affordability.

Although non-selective, its careful application in vineyards ensures clean rows. Best results come when weeds are actively growing. Use with a surfactant for improved uptake.

3. Rely 280 Herbicide

Rely 280 is a non-selective, post-emergent herbicide containing glufosinate ammonium. It disrupts photosynthesis, killing weeds within days. This herbicide is known for its vineyard safety when applied properly.

It controls broadleaf weeds and grasses, including glyphosate-resistant species. It is rainfast within four hours and works best on younger weeds. Vineyard managers trust it for clean rows and low phytotoxicity.

It breaks down quickly, minimizing environmental risk. Combine with a crop shield for added safety. Rely 280 is suitable for organic production in certain regions.

4. Matrix SG Herbicide

Matrix SG uses rimsulfuron to deliver both pre- and post-emergent control in vineyards. It targets tough perennials and annual weeds. Matrix is selective and safe for use in bearing vineyards.

It provides up to six months of residual activity and is rainfast within 24 hours. It works well in tank mixes for enhanced control. Vineyard operators value its versatility and long window of control.

Always apply to healthy vines with good soil moisture. Avoid contact with grape foliage. Matrix SG offers strong return on investment through long-term weed suppression.

5. Prowl H2O

Prowl H2O is a pre-emergent herbicide containing pendimethalin. It prevents seedling emergence by inhibiting cell division. Use it in established vineyards for broad-spectrum weed control.

It has low volatility and low odor, making it user-friendly. It should be activated with irrigation or rainfall. Growers appreciate its long-lasting control and low phytotoxicity.

Prowl H2O is compatible with several tank mix partners. Avoid applying to newly planted vines. It’s a dependable option for early-season weed management.

6. Goal 2XL

Goal 2XL is a contact herbicide that uses oxyfluorfen to manage broadleaf weeds. It works by inhibiting cell membrane function, resulting in fast weed desiccation. This herbicide is most effective when weeds are small and actively growing.

It’s rainfast within 4 hours and suitable for dormant-season vineyard use. Goal 2XL must not contact green vine tissue. Growers like its visual effect and compatibility with other herbicides.

Wear protective gear during application. Avoid windy days to reduce drift. Goal 2XL is best used as a burndown or pre-emergent solution.

7. Surflan A.S.

Surflan A.S. is a long-lasting pre-emergent herbicide containing oryzalin. It controls annual grasses and some broadleaf weeds. Applied to soil, it prevents weed seed germination in vineyard rows.

It is non-volatile and water-activated, providing up to 6 months of control. Surflan is often mixed with post-emergent herbicides for broader effect. It’s a favorite among vineyard managers for its reliability.

Do not apply directly to vines or foliage. Use a shield or apply during dormancy. Surflan is cost-effective and easy to apply with standard sprayers.

8. Alion Herbicide

Alion Herbicide provides residual control with indaziflam, a pre-emergent active ingredient. It inhibits cell wall formation in germinating weeds. Ideal for vineyards, it offers season-long control of grasses and broadleaf weeds.

Alion is rainfast within an hour and can be used on bearing and non-bearing vines. It must be applied before weed emergence. Users benefit from reduced spraying and labor over time.

It has excellent crop safety when label directions are followed. Use only in mature vineyards. Alion reduces resistance development through its unique mode of action.

9. Treevix Herbicide

Treevix offers post-emergent control with fast-acting burndown. Its active ingredient, saflufenacil, causes cell membrane disruption. Treevix controls many resistant broadleaf weeds.

It is rainfast within one hour and visible effects appear within 24 hours. It can be tank-mixed for extended control. Vineyard professionals like its quick action and short re-entry interval.

Apply only to dormant vines. Avoid green bark and leaves. Treevix provides an efficient way to clean rows quickly.

10. Venue Herbicide

Venue uses pyraflufen-ethyl for broadleaf weed control in vineyards. It acts fast by disrupting photosynthesis and cell function. Venue is often tank-mixed with glyphosate or glufosinate for better efficacy.

It is labeled for both dormant and growing-season use. Application during early growth stages of weeds enhances control. Vineyard owners use it for its quick visual results.

It breaks down rapidly, reducing environmental impact. Avoid application during high wind. Venue is a solid pick for rotational weed management programs.

Buyer’s Tips for Choosing Vineyard Herbicides

• Check for crop safety: Use only herbicides labeled for grapevines.
• Pre- vs post-emergent: Combine both for season-long control.
• Rainfastness matters: Look for products that resist wash-off.
• Watch application timing: Apply when vines are dormant when possible.
• Use shields for sprays: Prevent drift and vine injury.
• Tank mix compatibility: Combine products for broader spectrum.
• Rotate modes of action: Prevent weed resistance with rotation.
