Understanding what to add ensures better weed control in various environments. It also saves time, labor, and money in the long run.

This article outlines the top 10 best additives you can mix with glyphosate for boosting glyphosate’s power. Discover what works, how it helps, and why it matters.

What Can I Add To Glyphosate To Make It More Effective?

1. Ammonium Sulfate (AMS)

Ammonium sulfate is a common additive used to enhance glyphosate effectiveness. It works by conditioning hard water and preventing calcium and magnesium ions from binding with the herbicide.

This helps glyphosate penetrate plant tissue better. AMS is particularly useful in areas with hard water sources. It helps glyphosate maintain its chemical integrity during mixing and application.

Weed control becomes significantly more efficient. Using AMS with glyphosate can result in quicker absorption by the weeds. This ensures faster results and less herbicide waste. It’s ideal for use on large farms and tough perennial weeds.

Pros:

• Water conditioner
• Faster uptake
• Cost-effective
• Enhances potency
• Easy to mix
• Compatible widely
• Boosts penetration

Cons:

• Requires measuring
• May cause clogging
• Needs clean storage

2. Surfactants

Surfactants reduce the surface tension of water, allowing glyphosate to spread evenly on plant surfaces. This leads to better coverage and absorption into weed foliage. The result is a more effective herbicide application. These additives are especially effective against waxy or hairy weed leaves. They help glyphosate overcome the barriers that would otherwise repel the spray. Enhanced contact increases the chance of weed death. Non-ionic surfactants are commonly recommended with glyphosate. They are neutral and do not interfere with the herbicide’s chemical makeup. Their use can significantly improve results.

• Pros:
  • Improves coverage
  • Helps absorption
  • Works on waxy leaves
  • Widely available
  • Easy to use
  • Economical choice
  • Boosts control
• Cons:
  • May foam
  • Needs dilution
  • Possible eye irritant

3. Crop Oil Concentrates (COCs)

Crop oil concentrates are petroleum-based oils that help glyphosate penetrate the waxy cuticles of weeds. They work by softening the outer layer of leaves for deeper herbicide absorption. This results in more lethal contact with target plants. COCs are best used when weeds are mature and resistant. They improve the action of glyphosate on stubborn species. Their efficiency makes them a favorite among commercial applicators. These additives are particularly helpful in dry, hot climates. They slow down evaporation and increase the window of herbicide action. COCs also enhance rainfastness.

• Pros:
  • Penetrates waxy leaves
  • Increases rainfastness
  • Works on tough weeds
  • Long-lasting
  • Useful in heat
  • Lowers evaporation
  • Improves control
• Cons:
  • Can burn plants
  • Not eco-friendly
  • Higher cost

4. Methylated Seed Oils (MSOs)

Methylated seed oils are made from seed-based vegetable oils combined with surfactants. They help glyphosate enter plant tissues more quickly. MSOs are known for their compatibility with multiple herbicides. They perform well in tough conditions, such as low humidity and high temperatures. MSOs are ideal for drought-stressed or mature weeds. Their use increases herbicide activity and effectiveness. MSOs are suitable for use with a variety of broadleaf and grass herbicides. They are commonly used in both agriculture and landscaping. Their versatility makes them a valuable glyphosate additive.

• Pros:
  • Fast absorption
  • Versatile usage
  • Works in heat
  • Safe for crops
  • Reduces drift
  • Enhances effect
  • Easy to mix
• Cons:
  • Needs precision
  • More expensive
  • Not for all crops

5. Urea Ammonium Nitrate (UAN)

UAN is a liquid fertilizer that improves glyphosate absorption through plant leaves. It acts by increasing nitrogen levels, making the plant more susceptible. This speeds up the herbicide’s effect. UAN is especially effective on fast-growing weeds. It helps create a stress response in the plant, allowing glyphosate to act faster. This additive is popular in large-scale farming. Mixing UAN with glyphosate should be done carefully to avoid crop damage. It’s best used in pre-plant or post-harvest applications. Proper usage results in excellent weed control.

• Pros:
  • Increases nitrogen
  • Speeds reaction
  • Works on fast weeds
  • Fertilizer benefit
  • Easy to mix
  • Great for farms
  • Increases uptake
• Cons:
  • Can burn leaves
  • Needs care
  • Can harm crops

6. Humic Acids

Humic acids improve soil quality and plant health while enhancing glyphosate’s performance. They act as chelating agents that help herbicide uptake. Plants absorb glyphosate more efficiently. Humic acids can increase the permeability of cell membranes. This allows for better herbicide translocation within the weed. They work well with both foliar and soil applications. These additives are organic and safe for the environment. They provide dual benefits of weed control and soil enrichment. Suitable for sustainable agriculture practices.

• Pros:
  • Improves uptake
  • Enhances soil
  • Eco-friendly
  • Boosts permeability
  • Safe to use
  • Multi-functional
  • Organic source
• Cons:
  • Slower effect
  • Can stain equipment
  • Needs frequent use

7. Citric Acid

Citric acid helps lower the pH of spray solutions. Glyphosate performs better in slightly acidic conditions, making citric acid a helpful additive. It ensures the herbicide remains active longer. It also works as a chelating agent, binding to minerals in hard water. This prevents deactivation of glyphosate. It’s particularly useful in high-mineral water sources. Citric acid is inexpensive and readily available. It’s often used in combination with surfactants and AMS. This makes it a reliable additive in various farming environments.

• Pros:
  • Lowers pH
  • Readily available
  • Prevents binding
  • Enhances stability
  • Cost-effective
  • Multi-use additive
  • Non-toxic
• Cons:
  • Can irritate skin
  • Requires pH test
  • Short shelf-life

8. Vinegar (Acetic Acid)

Vinegar contains acetic acid that can help break down plant cell walls. This makes glyphosate more effective at penetrating weeds. It’s especially useful for spot treatments. It is a natural and safe additive that enhances the weed-killing action of herbicides. It’s also biodegradable and eco-friendly. Useful for organic gardening practices. However, vinegar should be used cautiously to avoid crop damage. Only apply in target areas. It’s best for small gardens or localized weeds.

• Pros:
  • Eco-friendly
  • Biodegradable
  • Natural option
  • Aids penetration
  • Spot treatment
  • Organic safe
  • Low toxicity
• Cons:
  • Strong smell
  • Limited use
  • Can harm crops

9. Liquid Dish Soap

Liquid dish soap can act as a surfactant when mixed with glyphosate. It helps break down surface tension and improves herbicide adhesion to leaves. This increases overall coverage. It’s a cost-effective and readily available solution for small-scale users. Many gardeners use dish soap for home-based weed control. It’s also safe for many plant types. However, commercial-grade surfactants are more reliable. Use dish soap as a last resort or in emergency situations. Its efficiency may vary with weed types.

• Pros:
  • Easy access
  • Cheap option
  • Breaks tension
  • Improves stickiness
  • Garden-friendly
  • Simple mixing
  • Useful backup
• Cons:
  • Not professional
  • May not mix well
  • Variable results

10. Iron Chelates

Iron chelates help glyphosate work better by binding free ions in hard water. This prevents interference during herbicide application. It ensures glyphosate remains active and efficient. Iron chelates can also act as micronutrient supplements for crops. They enhance the weed-killing process while boosting plant health. This dual function is beneficial in integrated farming. They are especially useful in alkaline soil regions. This helps ensure better herbicide efficiency in difficult conditions. Their impact on glyphosate stability is well-documented.

Pros:

• Chelates minerals
• Boosts effect
• Improves health
• Dual-purpose
• Soil-friendly
• Alkaline suitable
• Easy to use

Cons:
