Sclerotinia and blackleg are the two most damaging diseases in Australian canola. And the higher the yield potential of the canola seed growers have planted, the more potentially costly any disease damage could be.
The same applies to key diseases in cereal crops with very high potential yields.
That’s why the release of new Revystar® is so significant.
Revystar is a co-formulated Group 3 and Group 7 fungicide unlike any other.
Just as advances in breeding have steadily increased the productivity of hybrid canola varieties, Revystar uses advances within two well-established fungicidal chemical groups to increase their effectiveness.
“The economics of growing hybrid canola make Revystar an especially good choice for foliar sprays in those crops,” says David Strong, BASF’s Market Lead – Canola (Seeds, Traits & Crop Protection). “Local trials and overseas experience have shown that Revystar consistently outperforms other fungicides with the same modes of action on the two most potentially costly diseases of canola in blackleg and sclerotinia. By preventing yield losses and reduced grain quality in such high-value crops, it will deliver an excellent return on a comparatively small investment.
“Revystar can also improve control of such key diseases as Septoria tritici and nodorum in wheat and both forms of net blotch in barley. When cereal crops have the potential to produce very high yields, that extra edge in performance and protection can be worth a lot of money.”
The game-changer in the Revystar formulation is Revysol®, an innovative DMI active. Revysol is the first ‘isopropanol azole’ and has a uniquely adaptable molecule that can change shape to bind strongly with mutated disease pathogens which older DMIs may no longer be able to control.
At a time when resistance to DMIs is becoming more apparent, that capacity makes Revysol a clear standout as the preferred choice in a crowded field of Group 3 fungicides, the rest of which are very similar.
Revystar delivers more than just the benefits of Revysol because its second active ingredient is also a ‘best in class’ contender. Xemium® is a next-generation Group 7 SDHI active.
“Given that most growers’ spray programs are likely to include a co-formulated Group 3 and Group 7 fungicide, it makes sense to upgrade to the new best-in-class option,” David explains. “Its very rapid uptake also makes it more suitable for use in tricky weather conditions during and after spraying than alternative fungicides.”
Revystar is registered to control sclerotinia and both seedling and upper canopy infection (UCI) blackleg in canola. “With a seed treatment like ILeVO® now providing such a high level of early protection against blackleg,” said David, “we recommend that growers apply Revystar at 20–50% flowering so they get the protection against both diseases instead of just one. In most cases, a spray at 20% flower for sclerotinia will also mean you pick up UCI blackleg infection which can be just as problematic in some seasons.”
Revystar is also registered to control 6 diseases in barley, including both forms of net blotch; 3 diseases in oats and oaten hay; and 5 diseases in wheat, including both Septoria tritici and Septoria nodorum, as well as for suppression of yellow leaf spot.
