    Aliette Fungicide

    By Mark on 07/11/2016

    Aliette is a great product. However, the manufacturer advises against using a surfactant/sticker/spreader with this product. "Due to ALIETTE(R) WDG Fungicide's acidic nature, do not tank mix with acid type compatibility spray adjuvants (e.g., Buffit(R) Spray-aide, Triton AG-44M) or with adjuvants designed to enhance pesticide penetration (e.g., Herbex(R) or Induce(R))."

Sort Questions
How do you mix Aliette WDG Fungicide in smaller quantities?

I have a 4 gallon sprayer and I need to know who much Aliette WDG to put in for my boxwood.

You would need to mix roughly 0.5 ounce of the Aliette with every 2 gallons of water to every 1000 sq/ft that you treat. The water will act as the carrier not the diluter.

Do you recommend to use a surfactant when applying Aliette WDG Fungicide?

Yes, adding a surfactant like Southern Ag Non Ionic surfactant, will allow for Aliette WDG Fungicide to stay on the surface you have sprayed. This helps promote better uptake of the product.

What is the mixing ratio of Aliette WDG Fungicide per gallon of water?

I am growing hops on a very small scale, spraying with a 4 gal back pack sprayer.


The mixing ratio is 0.5 oz. of Aliette Fungicide per two gallons of water. Water acts as a carrier with this product and will cover 1000 square feet.

Can I use Aliette WDG Fungicide if I sprayed copper last week?

What do I need to be concerned about or is there something I should mix with the Aliette to lessen any issues due to prior application? I read something on the label but don't quite understand it.


As long as 7 days has passed since the application of copper you should be ok to apply the Aliette WDG Fungicide.  The label is advising against tanking mixing with solubilized copper or applying back to back.
