The best way to prevent disease and pests is by providing the appropriate care for your plants. Proper location choice, air circulation, watering, and fertilization are the keys to your success. Phlox don't tend to have a lot of issues with pests of disease, but because they grow at ground level there are a couple things to watch out for. Mites can be treated naturally with neem oil, or insecticidal soap. For severe infections you can use pesticides like carbaryl, also known as Sevin. To determine if mites are an issue look for the foliage to be dull and webbing to appear. Phlox can, on occasion, encounter fungal issues especially when moisture is high and air circulation is low. Neem Oil is an organic method of treating and preventing some fungal diseases and pests. It can be effective, but the entire plant must be coated in order for this method to be effective. Water at the base of this plant to avoid fungal disease on the leaves. For severe fungal infections treat with a fungicide.
