General Information: This strain has been developed for worldwide commercial use to control crown gall. This species is used commercially to control crown gall, a tumorogenic plant disease caused by the ubiquitous soil-borne pathogen Agrobacterium tumefaciens, which affects susceptible woody plants worldwide. The pathogen is responsible for nursery and orchard losses among stone fruit trees, grapes, apples, pears, nut trees, caneberries, clematis, hops, kiwifruit, persimmons, roses and many ornamental annuals, trees and shrubs. Infected plants are usually weakened and unproductive due to their damaged root system.
