There are not any specific temperature guidelines with the Bayer Advanced Disease Control for Roses, Flowers & Shrubs. For best results per the product label, "Apply at the shorter interval specified under "Directions for Use" when disease or conditions favorable to disease (generally cloudy, wet and warm weather) are present. Prevent damage to your plants caused by disease by starting a spray schedule when diseases are likely in your area. For more information on what you can do to control plant diseases, contact your local County Extension Service (usually found in the White Pages of the phone book under the name of your county.)"
