Abstract

Orchard evaluation of five strains of Erwinia herbicola for control of blossom infection.

Abstract

Each E. herbicola strain grown in liquid culture was diluted and sprayed on blossom clusters of Idared apples when 75% of the blossoms were open. The next day the blossom clusters were inoculated with E. amylovora followed by a second application of the test treatments. All bacterial treatments reduced infection by an av. of 57% and streptomycin reduced infection by 84%. This paper was presented at the Fourth International Workshop on Fireblight held in Ithaca, NY, USA on 22-26 Jun. 1986.
