Green Crinkle Disease

Your Golden Delicious apple develops deep fruit depressions and pitting on one or two limbs, with discolored vascular strands beneath. Viral agents including apple stem pitting virus cause this serious issue. Use only virus-tested planting material and remove infected trees. The disease doesn't spread readily within orchards.

Use only virus-tested (and found to be free of all known viruses) planting and propagation material. Remove and destroy infected trees.
