Avocado Branch Canker Disease Management

  • Apr 16, 2013

The primary means of managing avocado branch canker disease is applying chemical treatment to any open wounds to prevent Botryosphaeriaceae spores from entering and initiating infection.

Other avocado grove cultural management practices that help prevent and manage branch canker disease are as follows:

  • Avoid pruning avocado trees during or immediately after rain
  • Prune out dead limbs and twigs where the pathogen pycnidia spore forming structures are
  • Dispose of dead wood and old fruit away from healthy avocado trees
  • Protect pruning wounds with chemical treatment
  • Properly irrigate avocado trees ensuring soils are free and loose and drain easily
  • Implement proper avocado tree fertilizer management
