Foliar fungicide offers wheat growers tool for resistance management
Few wheat varieties offer much in the way of genetic protection against Septoria tritici blotch infections, with reliance instead 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.
Syngenta has submitted an application to the Australian Pesticides and Veterinary Medicines Authority (APVMA) for the registration of ELATUS™ ACE to help growers with their resistance management programs.
ELATUS ACE possesses the active constitute Benzovindiflupyr, which has been through extensive field development between Syngenta’s Australian and European R&D teams.
“Benzo, as we call it in the field, belongs to the SDHI mode of action (Group 7),” Syngenta Technical Services Lead Trevor Klein said.
“ELATUS ACE combines Benzovindiflupyr and a DMI (Group 3) to create a foliar spray specifically for Australian conditions. Our trials have demonstrated excellent protection against Septoria and rusts, offering control over the broadest range of diseases of any foliar spray on the market.”
Trevor said it was 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.”
Trevor said ELATUS ACE would offer growers an excellent resistance management tool, pending APVMA registration.
“If rusts and Septoria are a reality in your district, look carefully at your resistance management strategy,” he said.
“Trials have demonstrated that ELATUS ACE has a good fit in a program with AMISTAR XTRA, and together represent a sound resistance management strategy.
“ELATUS ACE will prove particularly helpful as a preventative foliar spray at the first sign of disease, or by early stem elongation (GS 32).”
