UNIVERSITY TEST DATA
In recent university fungicide trials on turf diseases, no statistical differences were observed in comparing the efficacy of Prothioconazole 4L Select versus Densicor®.
The trials also show Prothioconazole 4L Select outperformed the combination of azoxystrobin and difenoconazole on both disease complexes.
