Sample alert: grape powdery mildew in West Azerbaijan

A floury coat on leaves and berries, with stalled cluster growth, is a common sign of powdery mildew. This text is not a definite diagnosis for your vineyard.

In the photo module, one picture of both leaf sides and of the cluster is enough. The result gives confidence, IPM steps and a pre-harvest interval. If confidence is low, the sample should go to a clinic.

A regional alert reaches only plots that registered grape. Keep the pre-harvest interval before picking for a shop or for export. Residue makes the quota unusable.
