Dusty Barroso, pest control adviser for BioSafe Systems, which produces ZeroTol, said, “ZeroTol 2.0 foliar applications gives the grower more options for controlling plant pathogens. It can be used as a standalone treatment or tank mixed with insecticides or fertilizers depending on IPM program needs.”
According to a spokesperson from the DPR, ZeroTol 2.0 is approved by the U.S. EPA for use on hemp up to the day of harvest. "In March, DPR approved USEPA’s label, meaning it’s registered in California for use on hemp as well. DPR has determined that the product label meets the 'legal use' criteria for cannabis in California, meaning that such use would not violate the legal prohibition on use in conflict with the pesticide label."
