Tools Needed
To apply Chlorothalonil DF Fungicide, a professional skid sprayer, sprinkler system, air assisted spray equipment, chemigation equipment, and various types of irrigation equipment can be used.
How to Use
- Step 1: Determine how much Chlorothalonil DF you will need by first calculating the acreage of the area you wish to treat. To do this, you will first need to get the square footage by measuring (in feet) and multiplying the area length times width (length x width = square footage). Once you have the square footage, divide by 43,560 to get acres (square footage /43,560 = Acreage). The general rate for using Chlorothalonil is 1 to 2.5 lbs. in 100 gallons of water per acre. So if you measured 3 acres to treat, you will need to mix 3 to 7.5 lbs. of product in 300 gallons of water. Applications rates vary depending on the disease and where you are applying.
- Step 2: Fill your spray tank with half the amount of water needed and then add the appropriate amount of Chlorothalonil DF based on your calculations. Add the remaining half of water and then agitate well to ensure the product is sufficiently mixed
- Step 3: Keep the agitator process running while making applications. Be sure to make even and thorough applications. Re-treatment applications depend on disease being controlled and the vegetation being treated.
Where to Use
Chlorothalonil DF Fungicide is ideal for use on tree crops, sod farms, golf course fairways, golf course tees, and greens, ornamental plants grown in fields, nurseries, or greenhouses.

When to Use
Applications of Chlorothalonil DF Fungicide should be applied when weather conditions are supportive of disease development. Applications can be repeated under these conditions using the application rates listed on the label.When treated label listed tree crops, the time to apply Chlorothalonil varies depending on the type of disease being controlled. Applications made during times of bloom can injure flowers and fruits.

Q:I have some brown areas on my Empire zoysia. I'm not sure if it is brown patch or Pythium. Will this work to fix the problem for both brown patch and Pythium? If so, how much do I use per gallon? Thanks.11/29/19A:Thank you for asking. Chlorothalonil DF Fungicide is labeled for use on Brown Patch, but not for pythium blight. Unfortunately, pythium blight can be mistaken as brown patch as it is similar in resemblance. Pythium blight will have a greasy look to it.
