Use ATAK to eradicate powdery mildew and improve your crops' health. The dual action of the formula combats and eliminates powdery mildew while improving your plants' immune systems. Use the formula once every week to keep your plants clean and shiny. Store the product in a safe and protected place and keep it away from extreme temperatures.
