Fontelis 12 is a suspension concentrate fungicide containing 20.4% Penthiopyrad. It is used for the prevention and control of various fungal diseases in a wide range of crops, including vegetables (such as tomatoes, cucumbers, and leafy greens), fruits (such as berries, stone fruit, and tree nuts), and certain ornamentals. It works by targeting specific fungal pathogens like Botrytis gray mold, powdery mildew, and various leaf spots. The product can be applied via various methods including soil application, in-furrow spray, drip irrigation, or foliar spray. When using in a tank mix, users must ensure compatibility with other products. Key handling notes include wearing long-sleeved shirts, long pants, shoes, and socks, and avoiding contact with water or edible crops during application. It is important to follow specific pre-harvest intervals (PHI) which vary by crop, ranging from 0 to 28 days.
