e0“This study investigated the efficacy of fungicide applications during flowering in forage maize using the overhead and dropleg spraying techniques as well as a combination for the control of Kabatiella zeae and mycotoxin-producing Fusarium species”
e2“Disease severities were significantly reduced on the upper leaves by the overhead application and the combination of the overhead and dropleg spraying technique, whereby the three spraying techniques were equally able to decrease the infestation on the yield-essential leaves around the main ear”

Other claims from this paper (10)
- Intervention effect The combination of overhead and dropleg spraying significantly reduced Kabatiella zeae disease severity on the upper maize leaves.
- Intervention effect The three spraying techniques were equally able to decrease infestation of the yield-essential leaves around the main ear.
- Intervention effect Fusarium inoculation of main ears at full flowering significantly increased DON and ZEN concentrations compared with natural Fusarium infection.
- Intervention effect Fusarium inoculation of main ears at full flowering did not affect dry matter yield.
- Observation The strongest K. zeae disease progression occurred after flowering on the upper leaves and on leaves around the main ear.
- Intervention effect No differences in dry matter yield were found between the fungicide application techniques.
- Intervention effect Fungicide application techniques significantly increased dry matter yield compared with the untreated control.
- Intervention effect Sub-canopy dropleg applications, alone or combined with overhead spraying, most effectively reduced DON and ZEN contamination.
- Intervention effect The applied fungicide reduced Fusarium infections of the main ears.
- Recommendation The dropleg technique offers an opportunity for improved protection of lower maize organs, especially in tall crops.
