In south-west New South Wales, there is a program approach to prevent potato diseases from becoming a problem, says Steven Serafin of Yenda Producers Co-operative. “Our production area is a little bit unique compared to other places. Target spot is a real concern, as is Sclerotinia. But it’s target spot that really knocks us about by the end of the season,” he said. Syngenta products have long been at the core of his fungicide programs, particularly AMISTAR® Top fungicide and SCORE® fungicide.
The arrival of MIRAVIS® fungicide in 2018 represented another shift in what Serafin would come to expect of target spot control, when applied at row closure helping to keep his canopy healthy. “Using MIRAVIS to start off with gave us target spot control that was more superior to what we had been using up to that point,” he said.
However, then there arrived another Syngenta fungicide, combining the active, pydiflumetofen, in MIRAVIS fungicide with proven fludioxinol creating the co-formulation MIRAVIS® Prime fungicide.
“When applied in a program, by utilising MIRAVIS Prime, it took pressure off our BRAVO and AMSTAR Top applications. Where we saw botrytis and Sclerotinia come in, once applied, MIRAVIS Prime started to eliminate those diseases and gave us a longer coverage period.” MIRAVIS Prime fungicide provides specialist protection against Sclerotinia in areas prone to the disease, in addition to target spot and botrytis.
