BASF Potato product manager Rob Storer said: "Ametoctradin prevents disease by inhibiting the infectious stages of the pathogen, through preventing zoospore formation, release and motility and through direct effects on the germination of sporangia. It will play a useful role in preventing both foliar and tuber blight."
The two new approved products, to be test marketed in the UK this year, consist of co-formulations with two other blight fungicides.
Resplend contains 300g/litre ametoctradin and 225g/litre dim- ethomorph and is formulated as a suspension concentrate.
Decabane contains 80g/kg ametoctradin and 480g/kg mancozeb formulated as a water dispersible granule.
