Continue to manage weeds in the orchard:

  • Control summer perennials such as field bindweed, bermudagrass, and johnsongrass.
  • Apply preemergence spray in fall based on weed surveys (combine with postemergence if needed), targeting dandelion, clovers, and curly dock to limit X-disease.
  • Keep tree bases free of vegetation to reduce problems with rodents in winter and peachtree borer in summer.

Seed cover crop in October – avoid using clovers that can host the X-disease pathogen and leafhopper vectors: Berseem, crimson, rose, subterranean, and sweet clovers.
