Symptoms
Squash Silver leaf symptoms have been observed on all types of squash and are common in many zucchini varieties. Symptoms further develop interveinally until the entire upper leaf surface is distinctively silver. Silvering does not occur on the underside of the leaf. When leaf silvering is severe, fruit color is lighter than normal. Yield reductions and poor fruit quality are usually associated with leaf silvering.
