Pre-bloom resistance induction for fire blight suppression
Author: Kenneth B. Johnson
Published: 2022
Summary: Suppression of fire blight (caused by Erwinia amylovora) with resistance-inducing materials was investigated. Solitary, prebloom treatment of Kudos/Apogee (prohexadione-Ca), Actigard, or Regalia were of little value. Three-spray, bloom period programs of Actigard only provided up to 75% infection suppression. Organic, bloom period spray programs that combined the materials, Regalia and LifeGard, provided 59% infection suppression.
