Recognition and management of diseases noted in 2020 will be covered as well:oak leaf blister, Tubakia leaf spot, apple scab, powdery mildew, rusts, Sclerotinia canker, and rose rosette—along with the new beech leaf disease.

Learning objectives:

  1. Participants will learn which insect pests were most problematic this year and what to expect next year as a residual effect.
  2. Participants will learn about pesky diseases from this season and emerging diseases such beech leaf disease.
  3. Control practices for all pests and diseases will be discussed.
