An eagerly awaited fungicide product that has delivered substantial yield gains in wheat and barley trials has received authorisation for use in Great Britain, confirms its manufacturer, Syngenta.

On 03 April 2024 Syngenta received the official decision by the Health and Safety Executive (HSE) for the approval of the active substance pydiflumetofen. On 05 April HSE also authorised the product MIRAVIS^® Plus, which contains pydiflumetofen, for use on a wide range of arable crops, including winter and spring wheat and barley, says Syngenta cereal fungicide portfolio manager, Lizzie Carr-Archer.

"MIRAVIS^® Plus contains an SDHI known as pydiflumetofen (ADEPIDYN^® technology) and will be available to the market in a co-pack with the tried and tested triazole fungicide, prothioconazole," Ms Carr-Archer explains.

"More detail on MIRAVIS^® Plus will be provided at an upcoming launch, but key points to note include that trials have shown it is extremely effective against the important diseases of Septoria tritici in wheat, and net blotch and Ramularia in barley. It has also been shown to provide robust potency against Rhynchosporium in barley, and significant reductions in Fusarium head blight in wheat and in DON mycotoxin.

"ADEPIDYN^® technology has been undergoing rigorous development in the UK for the last seven years and is already registered and used successfully in many wheat growing countries around the world, Miravis being the leading fungicide brand in the Canadian market. In the UK alone, it has been tested in over 500 trials, with a visible increase in green leaf area retention and significant yield improvement results, including yield increases in barley even in the absence of disease.

"Since announcing ADEPIDYN^® technology in GB in 2021, we have had an opportunity to conduct two full years of additional trials. This extensive testing and track record should give added confidence to British growers and advisors looking to use MIRAVIS^® Plus in the 2024 fungicide season."
