Product Overview

Daconil Weather Stik Fungicide will control diseases on professional turf and ornamental. Areas include golf course tees, fairways and greens, non residential turf grasses, ornamental turf grasses, sod farms, athletic fields and production ornamentals. It provides broad spectrum control with low resistance risk. It is classified as a Phthalimide, which stops the synthesis of amino compounds and enzymes. Daconil controls 14 turf diseases that include gray snow mold, dollar spot, brown patch, algae,gray leaf spot, leaf spot, anthracnose, rust fusarium patch, and red thread.

In ornamentals, Daconil controls more than 50 diseases, including scab and powdery mildew. Daconil Weather Stik Fungicide is sprayed on the leaf of the plant and the active ingredient, cholorothalonil stays on by the wax. After water is applied, a film forms on the leaf and then the active ingredient is mixed in with the water and redistributes over the leaf.  Disease spores are then unable to infect. This powerful fungicide makes it the ideal product for managing turf diseases.

Can I use Daconil Weatherstik on Boxwoods with Volutella?

What is the mix ratio? I have looked at labels online but I can’t tell how much Daconil to add to a gallon of water before spraying on Boxwoods? What is the best way to spray the boxwoods? What is the difference betweeen Daconil and Daconil Weatherstik?


To treat for volutella leaf blight, you would use 22 oz of Daconil Weather Stik Fungicide per 100 gallons of water on ornamentals, which breaks down to 0.22 oz per 1 gallon of water. Daconil Weather Stik has extra surfactant to help give you even coverage and better leaf penetration of the active ingredient.

Should I use Daconil Weather Stik or Daconil Zn to control Pestalotiopsis on Japanese Black Pine and Rhizosphaera on Colorado Blue Spruce? And can either of these be mixed with Floramite?

Neither Daconil ZN nor Daconil Weather Stik can be used on blue spruce but is safe for use on pine trees. Either can be mixed with Floramite. Be sure to do a small tank mix test first to ensure that there is no clumping between the two products. 

We would recommend using Clearys Spectro instead for blue spruce. This is safe for use on blue spruce trees and will kill and prevent diseases on various ornamentals.
