ZeroTol Algaecide/Fungicide from BioSafe Systems LLC has a newly updated label in California. The expanded label includes new applications for treatment of hard surfaces and greenhouse tools and equipment to prevent the spread of algal and fungal growth. ZeroTol is now labeled to treat several new organisms, including black spot, downy mildew, powdery mildew, leaf spot, Pseudomonas and Xanthomonas.
ZeroTol uses peroxygen chemistry to eliminate plant pathogens on contact. Because the peroxygen breaks down into water and oxygen after reacting, ZeroTol has a zero-hour REI and no run-off concerns. It can be used to treat plants, water and equipment. It is available in 2½-, 30-, 55- and 275-gallon sizes.
