Have you ever heard of spray adjuvants? They are also called "surfactants". These are herbicide additives that allow us to use less herbicides, yet maintain equal or greater effectiveness. By definition, adjuvants are additives that increase effectiveness or safety of a product.
There are many different types of adjuvants and each with a different purpose. Below is a list of commonly used adjuvants.
The Sticker and Spreader Spray Adjuvants.
Many lawn weeds have a protective coating similar to a waxed car. On these weed surfaces, herbicides can bead up and roll off. When this happens you may not get the control you are looking for and it may lead to repeated spraying. This is where a sticker and spreader can help greatly.
Sticker and spreaders are generally sold together as a single item in home and garden stores. You can also purchase professional sticker/spreaders at farm stores or at a professional turf and landscape supply stores. They are very easy to use. After reading the label, simply add the correct amount listed on the label directly into the sprayer along with the herbicide mixture you prepared.
Why is a Sticker/Spreader Important?
Note: They cannot be used with hose end sprayers or with fertilizers. They are designed to be added to your hand pump or power pressure sprayer when using herbicides and certain pesticides.
Some herbicides will already have a sticker/spreader added to it. Read the label carefully to be sure. If there is not one added, then the addition of this adjuvant may help the product to be more effective.
