UCONN IPM: Integrated Pest Management:UConn Grape IPM Message

As we head into the 1-5 inch shoot stage in wine grapes, vines should be protected with fungicides that are effective for Phomopsis cane and leaf spot and for black rot. This is especially true for sites that struggled with these pests last year. Predictive disease models that were run on weather collected from Connecticut vineyards indicated that infection risk was high for these important diseases. Although the recent weather has also been conducive to powdery mildew infection, the over-wintering inoculum is not mature yet.
