Rust Mite - UPDATE 8/10/2009

Rust mite are slowing down some vineyards and restricting early shoot growth. This damage seems to be the most severe in blocks that were pruned late this season.

This is seen as shoots with slow and perhaps stunted shoot growth with distorted leaves. It is too late for spraying to be effective this season. The stunting effects of Rust Mite are limited by the application of Sulfur at bud-burst.

With warm weather and good growing conditions, these any distorted shoots will begin to grow normally and the damage becomes difficult to detect by flowering.
