Septoria fungicide toolbox
The Septoria fungicide toolbox is limited to three main groups of chemistry: SDHIs, DMIs and multi-site fungicides.
SDHIs (succinate dehydrogenase inhibitors) remain effective against Septoria. They should be used preventatively when disease pressure is low, but disease risk is high. SDHIs offer broad spectrum control of other foliar diseases, but need to be used in moderation to protect them from the increasing threat of resistance.
DMIs (DeMethylation Inhibitors) such as BOLIDE® or STELLAR® are an important component in Septoria control and also provide broad spectrum control. Similar to SDHIs, DMIs are single-site chemistries, so protecting DMIs from resistance is key.
Multi-site fungicide PHOENIX® Fungicide (PHOENIX) is a vital tool in the control and management of Septoria. PHOENIX, containing the active ingredient FOLPET, affects several different metabolic sites within a pathogen and is protectant in action. Folpet has no known resistance and remains at a very low risk of resistance developing in cereal pathogens. In fact, ADAMA’s testing has confirmed no sensitivity shifts against Septoria.
Break the resistance cycle with PHOENIX and BOLIDE
Win the fight against key diseases by combining PHOENIX and BOLIDE, the ultimate duo for resistance management.
Septoria remains a key issue for New Zealand’s cereal industry. It can have a devastating impact on wheat crops. This is especially the case when Septoria becomes resistant to established fungicide modes of action. It is therefore even more important to practice good resistance management in the field.
