Select the phenological stage below to see a list of potential diseases that need to be managed during that time of year, and products that can be used to manage them. Not all diseases need to be managed for in all blocks and in all years. A grape phenological chart is provided below to help identify what stage of development your vineyard might be in.
Additional in formation is available on the Grape Decision Aid System (Grape DAS) to help determine the best timing for pesticide applications. Currently, models are available for: Grape Powdery Mildew, Grape Mealybug, Phylloxera, and Northern Rootknot Nematode.
