Envu releases new fungicide

Castlon is one of five products the company will debut in June 2024.


Envu announced Castlon fungicide will be available in June 2024.

Castlon is a new fluoxastrobin that can help mitigate 26 turf and 22 landscape/ornamental diseases. Castlon delivers control of multiple problematic turf diseases, including fairy ring, summer patch, brown patch, leaf spot and Pythium.

“Castlon fungicide is a strobilurin chemistry that is highly systemic in plants with a very fast rain uptake, making it a quick performer against foliar and root diseases,” said Dr. Jesse Benelli, Green Solutions Team specialist at Envu. “There aren’t many standalone products that can control brown patch and Pythium blight at the same time. Typically, applications require tank mixtures, but Castlon fungicide does both.”

Castlon can be tank-mixed with Mirage Stressgard fungicide, which features tebuconazole as an active ingredient, for improved plant health benefits. Envu announced superintendents are eligible for a $50 rebate on each bottle of Mirage Stressgard for every unit of Castlon they purchase.

“We are incredibly pleased to make this solution available for our customers alongside our recently introduced Resilia root health solution and trusted Stressgard brand fungicides,” Benelli said. “When put into rotational application programs, they can help ensure plant health and disease protection all season long.”

In addition to Castlon fungicide, Envu also is releasing four new herbicides:

  • Acclaim Accelerate for control of three- to five-tiller crabgrass and other challenging midsummer weeds, including torpedograss on warm-season turfgrass
  • Terradex Power Premix for broad-spectrum control of broadleaf weeds such as thistle on primary and no-mow roughs
  • Terradex Crabgrass & Broadleaf to provide postemergence control of both grassy and broadleaf weeds applied as a late-season cleanup.
  • Terradex Quick Strike to control broadleaf weeds fast with results in 24 to 48 hours while becoming rainfast in six hours
