Dormancy

Manage orchard floor vegetation.

• Continue postharvest weed assessment in late fall to identify those that were not controlled by fall treatment.
• Keep records (example winter weed survey form PDF).

Assess mummy nut levels on the ground and in trees for navel orangeworm management.

Look for scale pests and mites and evidence of parasitism.

• Examine scaffolds, limbs, branches, spurs and prunings, for scale pests (walnut scale, San Jose scale, frosted scale, European fruit lecanium) and European red mite eggs.
• Note areas of concern for possible treatment.

Other pests you may see:

• Fruittree leafroller egg masses
• Italian pear scale
• San Jose scale
