Mechanistically compatible mixtures of bacterial antagonists improve biological control of fire blight of pear.
Mixtures of biological control agents can be superior to individual agents in suppressing plant disease, providing enhanced efficacy and reliability from field to field relative to single biocontrol strains. Nonetheless, the efficacy of combinations of Pseudomonas fluorescens A506, a commercial biological control agent for fire blight of pear, and Pantoea vagans strain C9-1 or Pantoea agglomera...
متن کاملinvestigation of changes in antioxidant enzyme and total phenol level in some pear cultivars inoculated with fire blight disease
fire blight, caused by the bacterium erwinia amylovora, is one of the most destructive diseases of plants in the rosaceae subfamily pomoideae. the objective of this study was to determine the level of resistance of 30 pear cultivars and describe the biochemical changes induced in some resistant and susceptible cultivars. the level of resistance was determined by the length of the fire blight le...
متن کاملField evaluation of carrot cultivars for susceptibility to fungal leaf blight diseases in New York
Carrot cultivars grown in New York were evaluated for susceptibility to the fungal leaf blight pathogens Alternaria dauci (1999) and Cercospora carotae (2000–03) in an experimental field under continuous carrot cultivation since 1996. Replicated plots were established in a randomized complete block design. Plants were rated for disease incidence and severity at regular intervals. Cultivar susce...
متن کاملthe study of biological control of pear fire blight caused by erwinia amylovora by some antagonistic bacteria
fire blight is an important worldwide disease of pome fruits that control of which through antibiotics is particularly critical. in this case and in absence of another chemical methods, the biocontrol methods can be considered as the best alternative for control of fire blight. in this study efficacy of 5 isolates of antagonistic bacteria belongs to pseudomonas fluorescens and pantoea agglomera...
متن کاملRelative attractiveness of colour traps to pear psylla in relation to seasonal changes in pear phenology
Monitoring of pear psylla (Cacopsylla pyricola (Förster), Hemiptera: Psyllidae) prior to spring bud break could aid in predicting the size of subsequent spring populations and lead to improved proactive management decisions. Yellow traps are commonly used to monitor hemipteran pests including pear psylla, but very little is known regarding seasonal changes in attractiveness of yellow traps or r...
