Watch Disease Spores Explode on YouTube

Watch disease spores explode with a new YouTube video clip of the exciting activity of Medallion TL. The video highlights the crucial importance of early protection against turf disease spore germination to stop leaf damage

The explosive activity of the new Syngenta turf fungicide, Medallion TL, can now be viewed on-line, with a YouTube video clip showing just what happens when treated disease spores rapidly absorb water, to the point where they quite literally explode and are rendered harmless to turf.

Syngenta Technical Manager, Dr Simon Watson reports the video clearly demonstrates how rapid mycelial growth of untreated spores can penetrate the leaf surface during early disease infection and cause damage to the leaf surface. “This highlights the importance of preventative application to stop spore germination.

“Medallion TL locks onto the membrane protein structures of specific selected turf disease spores. It triggers them to rapidly absorb water, to the point where they swell and burst. This happens so quickly there is no time for the spore to grow and infect the leaf, thus preventing damage to the leaf.”

Dr Watson adds that importantly this activity on disease pathogens not only takes place on the leaf surface to protect against infection, but also in the thatch and at the soil surface to provide effective Contact+ results. “This can reduce the sources of infection and thus lower disease pressure and risk. It means that Medallion TL can offer quite exceptional long-lasting protection.

“We see this as a really exciting opportunity to develop new disease control strategies.”

The Medallion TL video can also be viewed through the free GreenCast turf management website – – which includes further information on how it works and how to get the best results in turf management programmes.
