Plant Diagnostic Tool

The Double A Vineyards Grape Diagnostics Tool is designed to assist grape growers in diagnosing the likely cause of problems in the vineyard based on symptoms the grower has observed, and to suggest potential remedies, including the application of pesticides when warranted. While descriptions and photos of problems are primarily based on university research and publications, Double A Vineyards makes no claim of guarantee that the Grape Diagnostics Tool will result in an accurate diagnosis of the problem. Furthermore, while the information regarding the application of pesticides is true to the best of our knowledge at the time of publication, it is the grower’s responsibility to apply pesticides in accordance with local, state, and federal regulations. It is illegal to apply pesticides in a manner not recommended on the pesticide label. Read and understand the label before applying a pesticide – the label is the law.
