Other claims from this paper (12)
- Observation Pathogen strains had kasugamycin minimum inhibitory concentrations of 1.86 to 11.52 µg/ml for at least 95% growth inhibition.
- Observation Pathogen strains had oxytetracycline minimum inhibitory concentrations of 0.13 to 0.40 µg/ml for at least 95% growth inhibition.
- Observation Most collected strains, 95.3%, grew below 20 µg/ml metallic copper equivalent.
- Observation Moderately sensitive strains comprised 2.7% at 20 to 30 µg/ml copper equivalent.
- Observation Copper-resistant strains comprised 2% at 150 µg/ml copper equivalent.
- Observation Pathogenicity tests confirmed high virulence of copper-resistant olive knot strains.
- Intervention effect Kasugamycin matched copper hydroxide for reducing knots after inoculation with a copper-sensitive strain.
- Intervention effect Kasugamycin outperformed copper against a highly copper-resistant strain.
- Intervention effect Oxytetracycline was less effective than copper or kasugamycin.
- Intervention effect Applying bactericides within 24 h of inoculation gave higher disease control than later application.
- Intervention effect Pre-inoculation copper or copper-kasugamycin reduced knot incidence by more than 50% in greenhouse trials.
- Recommendation The authors concluded that bactericide timing after inoculation is critical for disease management.
