Daconcil Weather Stik Fungicide by Syngenta is used for the control of a broad-spectrum of turf and ornamental plant diseases. Daconcil Weather Stik contains the active ingredient chlorothalonil and a built-in surfactant to provide a greater sticking power for longer coverage and unsurpassed protection on grass blades, even after heavy rains or watering. Daconil Weather Stik is a great fungicide to use on residential lawns, producing a protective film on plants to make sure that disease spores don't infect the plant.

Tools Needed

Spray Daconil Weatherstik

To use Daconil Weather Stik you will need either a hose-end sprayer, handheld pump sprayer, backpack sprayer, or spray rig. For small household jobs, we recommend a handheld 1-gallon pump sprayer or a hose end sprayer.

How to Use

  • Step 1: Determine how much Daconil Weather Stik you will need to mix by calculating the square footage of the treatment site. To do this, measure (in feet) the area length and width, then multiply the two values (length x width = square footage). For a pre-disease treatment, use Daconil Weather Stik mix at a rate of 1.0 to 5.5 ounces per 1,000 square feet (rates vary depending on target disease).  For a post-disease treatment mix Daconil Weather Stik at a rate of 4.0 to 5.5 ounces per 1,000 square feet (rates vary depending on target disease). 
  • Step 2: Shake well and mix the product into your selected sprayer by adding half the required amount of water to the spray tank, followed by the appropriate measured amount of Daconil based on your calculations. Fill with the remaining half of the required amount of water and agitate the sprayer to ensure the product is mixed well.
  • Step 3: Spray the fungicide onto the leaf of the plant, placing the sprayer on a fan spray setting for even coverage. Apply water to the plant after spraying in order for a film to form and protect the plant from infection.
  • Step 4: Repeat applications can be made 7 to 28 day intervals if necessary.

Where to Use

Daconil Weather Stik is for use on sod farms, turf on golf courses, professional, and collegiate athletic fields, lawns, around commercial and industrial buildings, nurseries, greenhouses, conifers, and apricot, cherry, nectarine, peach, plum, and prune trees.

When to Use

Use Daconil Weather Stik either preventatively once a year during the growing season or whenever you have noticed and identified a disease on your plants.
