The only comments in regards to cactus on the Clearys 3336F product label is that it should not be used on Easter Cactus. We would recommend consulting with your County Extension Office for a positive id of the disease and for approved fungicide recommendations as 3336F Fungicide is only labeled for applications to lawns, turfgrasses, bedding plants, annual and perennial flowers, trees and shrubs.
