## Description

A wetting agent that increase coverage & penetration of any herbicide. Reduces the surface tension of water to insure more uniform coverage & penetration of weed killers.

Review: Great product - great price - This surfactant is a must have when spraying for weeds. It bonds to the weed to absorb the weed killer more effectively. It's not expensive and this brand is my go-to every time. Do yourself a favor and don't spray weeds without it.
Review: Great for hydrophobic soild - The “soil” where I live is basically decomposed sandstone and clay which is very hydrophobic. Even watering with a light mist results in runoff without any real penetration. I applied this with a hose-end sprayer and it worked like a miracle. Getting deep water penetration and no runoff. Plants are loving it. Cut my watering time in half and tripled the effectiveness. Highly recommend.

### ⭐⭐⭐⭐⭐ Good, use a lot
*by M***N on April 23, 2018*

Recommended. The label says 1-2 teaspoons per gal for general selective herbicides. I find you need closer to 1-1.5 tablespoons (3-4 teaspoons) / gallon. Why use this? Herbicides act faster - 3-5 days instead of a week+ More dead weeds at the same dose Less resprays Less effect on grass (weed vs. grass leaf surface area) 1tbspn/gal means 256 gallons of spray can be made Surfactants are much cheaper than herbicides This surfactant is low foaming, thus I believe it is of high quality. Dont waste time with the 16oz / pint. You’ll use it in a season. A gallon will last far too long. Tip1: Also, I’ve had good luck using this with Methylated Seed Oil (MSO). MSO is definitely not required though it helped with very mature weeds. Tip2: For general weeds don’t use plain 2-4D like I did. Get a mixture. Add either: quinchlorac, dicamba, tricylopr, sedge hammer, etc. 2-4D is amazing for dandelions, but most people have a lot of weed varieties: clover, creeping charlie, wild violet, spurge, etc. The mixture will save your sanity and resprays. Tip3: If it’s cold or the grass is not stressed you can mix a bit heavier than label. If it’s hot and sunny and you dont water 2x a day or 2x a week (depending on grass type) then mix at label rates or a bit less. Tip4: Look for the following chemical names Amine - summer spray (slower acting) Esters & acetic acid - spring & fall (faster acting but can burn grass more easily) Good luck. P.S. Donate to my lawn fund so I can actually mow grass not weeds. Hahah
