Alligare 90 Wetting Agent Can Help You Enhance the Effectiveness of Herbicides

ALLIGARE 90 is a general purpose nonionic surfactant, used to enhance spreading and coverage of sprays. ALLIGARE 90 may be used with various insecticides, fungicides, herbicides, PGR’s and nutrients at rates determined by pesticide label and field experience.


Often a problem with certain pesticides and chemicals is that they often run off of the plant and won't stick onto the plant to be able to be properly absorbed and do damage, With the help of a surfactant, or wetting agent, it improves the surface tension of such products so that they stick better onto the treated area. With Alligare 90, you can mix this product with any herbicide or pesticides that can allow a surfactant for enhancement.

Jeff G on Apr 5, 2018

I use fully strength (41 %) Round-Up (glyphousate) stump application to kill large Russian olive and Autumn Olive shrubs that are invading my property. This works well but is labor intensive. I am trying to kill small Russian olive and small autumn olive seedlings/plants one to four feet tall with foliar application of Round-Up diluted as per label. Because these invasives have waxy leaves, the water based Round-up does not get absorbed. Will this surfactant aid in absorbtion by the leaf or do I need an oil based adjuvant to get through through the waxy leaf.?
Greg S on Jul 6, 2018
BEST ANSWER: Hi Greg, I'm just a home owner and by no means a pro on this wetting agent. I did use Alligare (90 in combination with Triclopyr for my Creeping Charlie issue.I used it as directed with my hand pump sprayer and you could see the Triclopyr on the Creeping Charlie. Alligare 90 I would say worked great in sticking to every unwanted broadleaf weeds as well as the brush I sprayed. Hope this helps. John N Westchester Il
I have a small pond for raising koi, which is 14 ft diameter by 3 ft deep. There is a heavy growth of weeds at the very bottom of the pond. I am going to treat with diquat. Do I require a surfactant and could diquat/surfactant be applied by simply stirring the water with a large oar?

BEST ANSWER: I have used the diquat in my pond which is twice as big and two feet deeper without using surfactant and it worked well on my dense infestation on the bottom of the pond.
Can I mix Alligare 90 with Dithiopyr preemergent for crabgrass control?
Peague B on Dec 16, 2017
BEST ANSWER: Yes. Not needed for Dithiopyr alone, So I'm assuming you are adding a herbicide to your mixture. Just know that the Pre emergent needs to eventually be watered in and herbicide works best without rain/irrigation

I ordered acclaim extra yesterday, do I really need the surfactant?
crab grass front yard on Jul 24, 2017
BEST ANSWER: It is always recommended that a surfactant be used with herbicides and fungicide, it will make the product work more efficient. The cost if so low I am not sure why anyone would skip this process and adding a spray pattern indicator.

Once dry will this keep the insecticide from washing off in a rain?
Citrus guy on Jul 8, 2017
BEST ANSWER: Insecticides are meant to bind with the surface, so once they are dry, most will last about 30 to 90 days. Adding surfactant helps it work better, especially when applied on living grass, plants, etc.

The product is effective. I use it with Monsanto AquaMaster Herbicide on Lilly Pads.

Our company uses this product as an additive to our L&O applications and it definitely helps target weeds much faster than just herbicides alone.
