Quintec is a protectant fungicide used to control powdery mildew in various crops including artichoke, gourds, lettuce, melons, pepper, pumpkin, stone fruits, strawberry, winter squash, cherry, grapes, and hops. The active ingredient is quinoxyfen at a concentration of 22.58%. It is designed for use as a preventative measure, as it does not control existing or latent powdery mildew infections. The product can be applied via ground spray or aerial application, though aerial application is restricted to specific crops. When mixing, users should be aware that it can be tank-mixed with other fungicides, insecticides, or herbicides, but compatibility tests are recommended. Handling requires specific Personal Protective Equipment (PPE), including long-sleeved shirts, long pants, chemical-resistant gloves, and shoes plus socks. Users must follow Worker Protection Standard (WPS) requirements. Environmental precautions include avoiding drift to water surfaces and preventing contamination of water bodies. The label specifies strict application limits, such as maximum applications per year and pre-harvest intervals, to ensure crop safety and efficacy.
