New foliar fungicide controls Septoria and more key cereal diseases

Few wheat varieties offer much in the way of genetic protection against Septoria tritici blotch infections, with management being placed on foliar fungicide applications.

This has put increased pressure on triazole programs (Group 3) with agricultural departments across New South Wales, Victoria and South Australia having reported cases of resistance.

The registration of ELATUS™ ACE gives growers a vital resistance management tool. It contains Solatenol™, a powerful and globally proven SDHI fungicide that offers broad spectrum control of major wheat and barley foliar diseases, including Septoria.

The combination of Solatenol (Group 7) with a DMI (Group 3) creates a foliar spray specifically for Australian conditions. Syngenta trials have demonstrated excellent protection against Septoria and rusts, offering control over the broadest range of diseases of any foliar spray on the market.

Syngenta Technical Services Lead Pete Wilson said it’s important for growers and agronomists to be aware of their disease profile in their paddocks, and have a management program in place.

“Septoria survives season-to-season on wheat stubble and primary spores are spread widely as new crops emerge,” he said.

“Moisture plays a big part in Septoria infections. Rain tends to bring it on but it can also occur after heavy dews in late autumn and early winter, meaning that growers and farm managers should take all necessary precautions.”

If rusts and Septoria are a reality in your district, look carefully at your resistance management strategy.

“Trials have demonstrated that ELATUS ACE has a good fit in a program with AMISTAR XTRA, and together represent a sound resistance management strategy,” Pete said.
