Other claims from this paper (7)
- Observation All resistant Mycosphaerella graminicola isolates carried G143A.
- Method / resource The spore trapping PCR method quantified airborne ascospores and estimated resistant allele frequency.
- Observation Most ascospores were produced during wheat senescence.
- Intervention effect Resistant allele frequency rose from 35 to 80% after the first QoI application.
- Intervention effect After a second QoI application, resistant allele frequency in leaves and aerosols exceeded 90%.
- Observation Resistant ascospores spread as far as 85 m through the crop.
- Observation Fewer ascospores were detected after harvest, with resistant allele frequencies influenced by nearby wheat fields.
