Step 1

Premix Garlon, oil and surfactant in a clean metal container. You can use a variety of oils, including kerosene, diesel fuel or basal oil, depending on availability. The amount of ingredients you need depends on the size of land and type of weed you are treating, so read all product instructions carefully.

Step 2

Fill your mix tank halfway with clean water and begin agitating; most mix tanks include an agitator. Slowly pour the premix solution into the water, allowing the agitator to mix the two liquids.

Step 3

Fill the mix tank the rest of the way with clean water, continuing with moderate agitation. If possible, let the agitation continue while applying the herbicide.


For ground application, the premix solution should be 5 to 10 percent oil. For aerial application, you should use 1 part oil to 5 parts water. You can use up to 1 gallon of oil per acre of treated land.

Never let any water get into the premix. The water and soil will form a thick substance if they are not under constant agitation while being mixed.


Never mix herbicide solutions near open flame or a high heat source, as the ingredients are extremely flammable. Mix in a well-ventilated are to avoid inhaling fumes from the poison or the oil.
