Pinot Leaf Curl

Pinot leaf curl affects grapevine leaves, causing curling and distortion particularly in Pinot noir varieties. This viral condition limits photosynthesis and reduces grape quality. Remove infected vines and replant with virus-tested stock. Manage aphid vectors to prevent spread. This disease is best managed through prevention. These viral conditions are spread by insect vectors. Control the insect population to limit disease spread.

Management depends on catching it early. Scout susceptible plants regularly and remove affected tissue before the pathogen can spread. Improve growing conditions by addressing drainage, spacing, and irrigation practices. For persistent or severe cases, contact your local Master Gardener program or Extension office for treatment options specific to your host plants.
