How Metribuzin Works: Stops Weeds from Growing

What is Metribuzin herbicide?
Metribuzin is a weed killer that works by stopping weeds from making food. Like all plants, weeds use sunlight to create energy through a process called photosynthesis. Metribuzin blocks this process so that weeds cannot grow. Without energy, they turn yellow, dry up, and die.

Where Does It Work?

Metribuzin can enter the weed in two ways:

• Through the leaves – when sprayed after weeds have already grown
• Through the roots – when applied before weeds appear (pre-emergent)

This double method makes Metribuzin very flexible and effective at different stages of weed growth.

What Does Metribuzin Kill?

• It kills many kinds of broadleaf weeds (like pigweed, mustard, nightshade)
• It also controls some grassy weeds (like foxtail, crabgrass, and barnyardgrass)
• Yes—Metribuzin can kill grass if the grass is not part of the main crop

That’s why it’s important to only use Metribuzin herbicide on labeled crops, such as soybeans, wheat, and tomatoes.

Does Metribuzin Work on Corn?

Yes—but with care. Metribuzin on corn must be used at the right dosage and only on corn varieties that are tolerant to this herbicide. Some corn types may be sensitive, especially under poor weather or soil conditions. Always check the metribuzin herbicide label for crop-specific instructions.

Summary of Mode of Action

Action Step	What Happens
1. Spray the herbicide	Metribuzin touches leaves or reaches the roots
2. Enters the weed	It moves into plant cells
3. Stops photosynthesis	The plant cannot make energy
4. Weed dies	The plant turns yellow and stops growing

So when people ask, “what is Metribuzin?” — the answer is simple: It’s a smart herbicide that stops weeds from making food and keeps your crops clean and productive.

Where Can You Use Metribuzin? What Weeds Does It Kill?

Farmers use Metribuzin herbicide on many crops to control both broadleaf weeds and some grassy weeds. It is popular because it works well on different types of soil and in many farming systems.

Crops You Can Use Metribuzin On:

Crop	Application Timing	Notes
Soybeans	Before or after weeds appear	Very common use. Safe when applied correctly.
Wheat	Before or shortly after weeds emerge	Controls early weed pressure.
Corn	Before weeds grow (pre-emergence)	Only for certain tolerant corn types.
Potatoes	Before or soon after planting	Helps prevent weed competition early.
Tomatoes	Before transplant or after planting	Controls weeds during early crop stages.
Alfalfa	Before or after planting	Helps protect long-season crops.

Always read the metribuzin herbicide label to check if your crop is supported.

What Weeds Does Metribuzin Control?

Metribuzin works on many problem weeds that lower yields and compete with crops for nutrients, water, and sunlight.

Broadleaf Weeds:

• Pigweed
• Lambsquarters
• Mustard
• Nightshade
• Velvetleaf
• Chickweed
• Ragweed
• Cocklebur

Grassy Weeds (Yes, it can kill some grasses):

• Foxtail
• Barnyardgrass
• Goosegrass
• Crabgrass
• Wild oats

So if you’re wondering, “does Metribuzin kill grass?” — the answer is yes, but mostly the unwanted types. Make sure your crop isn’t sensitive before spraying.

Important Tips for Crop Safety

• Metribuzin is safe for labeled crops, but you must use the correct dose and timing.
• If your crops are under stress (from drought, flooding, or disease), do not apply.
• Always perform a small test area if unsure, especially for corn and soybeans, which may react differently depending on soil and weather.

Knowing exactly where and how to use Metribuzin helps prevent crop injury and gives you clean fields with fewer weeds.

How to Apply Metribuzin: Rates, Timing, and Method

To get the best results from Metribuzin herbicide, it’s important to apply it at the right time and in the correct amount. This helps kill the weeds without hurting your crops. Metribuzin is usually applied as a spray mixed with water and sprayed evenly across the soil or crop surface.

Application Chart by Crop

Crop	When to Apply	Dosage (per hectare)	Method
Soybeans	Before planting or early after sprouting	280–560 g/ha	Spray evenly over the soil surface
Wheat	Before or soon after weeds appear	220–440 g/ha	Apply when weeds are small
Corn	Before weeds emerge	220–500 g/ha	Make sure soil has enough moisture
Potatoes	Before weeds grow or just after planting	550–1120 g/ha	Apply before crop and weeds emerge
Tomatoes	After transplanting or before weeds appear	200–400 g/ha	Apply carefully around young plants
Alfalfa	Before or after emergence	280–560 g/ha	Use for season-long weed control

Always read the metribuzin herbicide label before spraying.

How to Mix and Spray

Metribuzin is powerful and effective, but only when used carefully and correctly.

Metribuzin Tank Mix Combinations: Stronger Weed Control When Mixed Right

Sometimes, using Metribuzin alone is not enough—especially when the field has many types of weeds or herbicide-resistant plants. In these cases, farmers often mix Metribuzin with other herbicides to get better, longer-lasting results.

Here are some of the most common and effective Metribuzin tank mix partners:

Metribuzin + Sulfentrazone

• Use: Soybeans
• Targets: Broadleaf weeds and tough grasses like waterhemp and pigweed
• Benefit: Improves control of resistant broadleaf weeds
• Application: Pre-emergence

Metribuzin + Atrazine

• Use: Corn
• Targets: Annual grasses and broadleaf weeds
• Benefit: Widely used for pre-emergent corn weed control
• Note: Only for Atrazine-labeled areas

Metribuzin + Flumioxazin

• Use: Soybeans, potatoes
• Targets: Early-season broadleaf weeds
• Benefit: Long residual effect, keeps fields cleaner for longer
• Timing: Pre-plant or pre-emergent

Metribuzin + Glyphosate

• Use: No-till farming systems
• Targets: Green emerged weeds before planting
• Benefit: Strong “burndown” action + soil residual control
• Timing: Before planting

Metribuzin + S-Metolachlor

• Use: Corn and soybeans
• Targets: Both grasses and broadleaf weeds
• Benefit: Two modes of action for broader control
• Timing: Pre-emergence, especially in high-rainfall zones

Tips for Safe Mixing

• Always mix in this order: water → Metribuzin → other herbicide
• Do a jar test first to check compatibility
• Do not mix with strong acids or very alkaline products
• Read all labels to ensure each product is approved for the crop
• Keep tank contents agitated while spraying

Why Use Mixes?

• Wider weed spectrum: Controls weeds that Metribuzin alone might miss
• Resistance management: Slows weed resistance to any single herbicide
• Longer weed control: Residual partners keep fields clean for weeks

Mixing Metribuzin correctly means fewer weed problems and fewer trips back to the field.

• Keep away from food, animal feed, and drinking water
• Store in the original, sealed container to prevent contamination
• Shelf life: 2 years from the date of manufacture if stored properly

Make sure your warehouse is clean, protected from rodents, and organized by chemical class to avoid accidental mixing with incompatible products.

Safe Handling Practices

Metribuzin is generally safe when handled correctly, but basic personal protection is required during mixing and spraying:

• Wear chemical-resistant gloves, long sleeves, and pants
• Use safety goggles or face shield to protect eyes
• If applying large volumes, use a respirator or mask
• Wash hands and exposed skin with soap and water after handling
• Avoid eating, drinking, or smoking during use

When cleaning spray equipment, do not dump rinse water into rivers or canals. Use designated rinse areas or recovery tanks to reduce environmental impact.

Environmental Safety

Metribuzin is toxic to some aquatic plants and fish, especially if applied near water bodies. To protect the environment:

• Do not apply near lakes, streams, or irrigation ditches
• Avoid spraying before heavy rain to reduce run-off
• Follow buffer zones and local guidelines for protected areas
• Triple-rinse empty containers before disposal

Empty containers should be:

• Punctured and discarded according to local pesticide regulations
• Not reused for storage of food, water, or other chemicals

Crop Safety and Weather Conditions

Crops can be harmed by Metribuzin if:

• The soil is too sandy or too light
• There’s been recent heavy rainfall or drought
• The plants are already under stress from disease or poor nutrition

Always test the herbicide on a small area of the crop if you’re unsure about soil type or weather impact. Avoid applying Metribuzin during extremely hot, dry, or windy conditions, as this may increase the risk of injury or reduce herbicide performance.

Good safety practices protect not only your field, but also your workers, your equipment, and your final yield.

Frequently Asked Questions (FAQ)

What is Metribuzin and how does it work?

Metribuzin is a selective herbicide used to control many types of weeds in crops like soybeans, wheat, corn, potatoes, and tomatoes. It works by blocking photosynthesis in weeds, which means it stops the plants from making energy. The weeds then turn yellow and die. Metribuzin is absorbed by both roots and leaves, so it works well before and after weeds appear.

What weeds does Metribuzin kill?

Metribuzin controls a wide range of broadleaf weeds like pigweed, lambsquarters, and chickweed, as well as grassy weeds such as foxtail, crabgrass, and barnyardgrass. If you’re wondering, “does Metribuzin kill grass?”, the answer is yes—it can kill many types of unwanted grass weeds. However, you should avoid using it on grass crops that are not labeled as safe.

Can I use Metribuzin on corn?

Yes, but with care. Metribuzin on corn is only recommended for corn varieties that are tolerant to it. You must apply the herbicide before weeds emerge, and always use the correct dosage. Some types of corn may show injury if Metribuzin is over-applied or if the soil is too sandy or wet.

Is Metribuzin safe for soybeans?

Yes. Metribuzin is commonly used on soybeans, especially in pre-emergent or early post-emergent programs. However, soybeans can be sensitive to Metribuzin if the soil is too light, or if the crop is stressed. Always check your soil type and follow label instructions. For new fields, doing a small test patch is a good idea.

What is the difference between Metribuzin 70 and Metribuzin 75?

The number refers to the percentage of active ingredient in the product.

• Metribuzin 70% WDG contains 70% active content and is widely used in commercial farming.
• Metribuzin 75DF or 75WG contains 75% active content and may offer slightly stronger effects at lower doses.
  Both are effective and the choice often depends on price, spraying system, and local preferences.

Can Metribuzin be used with other herbicides?

Yes. Metribuzin herbicide is often mixed with other weed killers to get better control or stop herbicide resistance. Common partners include glyphosate, sulfentrazone, flumioxazin, and atrazine. Always perform a jar test to make sure the products mix well, and read the labels to confirm crop safety.
