Garden Phos is a systemic fungicide that controls a wide range of fungal problems in the vegetable garden. Made with salts of phosphoric acid, this product will effectively control powdery mildew, downy mildew, pythium, late blight, and more in common vegetable crops. Garden Phos is particularly useful to manage mildews in cucumbers, cantaloupes, summer squash, winter squash, watermelons, and pumpkins. For nightshades including tomatoes, peppers and eggplant, it does a great job of mitigating late blight that may be accelerated as temperatures warm and humidity increases in the mid summer months. It can also be used as an effective fungicide on root crops like carrots, potatoes, and onions.
