Other claims from this paper (11)
- Observation G. graminis var. tritici isolates varied in in vitro sensitivity to PCA and Phl.
- Observation Four G. graminis var. avenae isolates were insensitive to both antibiotics in vitro.
- Observation The tested G. graminis var. graminis isolate was insensitive to PCA at 1.0 (mu)g/ml.
- Intervention effect P. fluorescens 2-79 suppressed take-all caused by two PCA-sensitive pathogen isolates.
- Intervention effect P. chlororaphis 30-84 suppressed take-all caused by two PCA-sensitive isolates.
- Intervention effect PCA-producing strains had reduced or absent suppression of take-all from PCA-insensitive isolates.
- Intervention effect P. fluorescens Q2-87 suppressed take-all caused by three Phl-sensitive isolates.
- Observation Suppression of take-all caused by Phl-insensitive isolates was not significant.
- Mechanism Additional mechanisms beyond PCA contribute to take-all suppression by strain 2-79.
- Observation Pathogen isolates insensitive to PCA and Phl occur in the population.
- Recommendation The authors favor mixtures of Pseudomonas with distinct suppression mechanisms to manage take-all.
