Adjuvants

Adjuvants are chemical compounds that can be mixed into a herbicide spray solution to enhance the effectiveness of the herbicide and boost its performance. The word “adjuvant” is a catch-all term that describes a number of different chemical enhancements such as non-ionic surfactants, crop oils, anti-foaming agents, drift retardants, spray buffers and spray pattern indicators or dyes among others.

Adjuvants can improve the effectiveness of a herbicide by modifying the herbicide solution to be able to apply more evenly on the plant or to reduce the surface tension of a plant (known commonly as spreaders and stickers). This essentially makes the herbicide kill undesirable weeds more efficiently and quickly.

Adding adjuvants to a pesticide product is very easy to do. Simply add a minuscule amount, following label directions for how much exactly, to a tank sprayer that contains a pesticide mixture and shake and begin spraying.

Recommendations

Alligare 90 Surfactant Wetting Agent

Alligare 90 Wetting Agent is a non-ionic low-foam surfactant. It is used to enhance various types of pesticides, insecticides, and herbicides. When applied, it helps the active products spread evenly and improves sticking so the active ingredient remains on surface areas for maximum results.

Alligare MSO (Methylated Seed Oil)

Alligare MSO (Methylated Seed Oil) is an oil-based adjuvant formulated for use with pesticides or herbicides that may require an oil adjuvant to get best results out of the product. MSO does a great job of penetrating the thick waxy coating of certain weeds and is able to penetrate weeds that are under stress.

Super Marking Dye

Alligare Super Marking Dye is a high strength blue marking dye that is a colorant used to monitor spray applications. The dye helps during the spraying process by making it easy to indicate where you have sprayed to prevent overspraying and drift into unwanted areas.

These expert-recommended adjuvants can be mixed with any weed killer to help enhance your spray application and make it easier to perform treatments.

In some herbicide formulations, adjuvants are already included in the formula while others are sold separately and recommended to be added to a herbicide solution before applying it to the targeted plantlife.

It is very important to read the instructional label on the herbicide for any information in regards to whether adjuvants can be added to the product or any other important details when mixing a recommended adjuvant.

• Selected Adjuvant Product

• Handheld or Backpack Sprayer

PPE

• Chemical Resistant Gloves
• Dust / Mist Mask
• Safety Glasses

Step 1: Mix up the Insecticide concentrate

Make sure that you always read and follow the label instructions for proper mix and usage rates. Fill the sprayer halfway with water and then add the appropriate amount of product for your application. Fill the sprayer the rest of the way with water and agitate the sprayer until the solution is well mixed.

Step 2: Add And Mix The Adjuvant

To use spray your selected adjuvant, read the product label to determine how much of the product you will need. After that, you simply fill the sprayer with the required amount of water and then measure the amount of adjuvant needed then pour it into a sprayer and agitate your sprayer gently to ensure it is thoroughly mixed.

Step 3: Apply the Spray and Adjuvant Mixture To The Target Area

With your PPE on, begin applying the adjuvant/herbicide mixture you created the target area needing to be treated.

Key Takeaways

• Adjuvants are essentially a sort of enhancement chemical that will improve the effectiveness of a herbicide chemical, making it kill more undesirable weeds more efficiently and quickly.
• To use adjuvants, all you need is a selected pesticide, an adjuvant such as a plant penetrant or surfactant (Alligare 90) and a handheld sprayer.
• The adjuvants we carry give you the most value for the price. You won’t find them at big box stores as they are specialty items.
