BASF researchers have confirmed the discovery of a unique mode of action for Initium fungicide. The findings have shown that Initium inhibits fungal activity by binding to the stigmatellin subsite in the respiratory complex III of the fungus. This means that Initium is the first and currently the only fungicide in this classification and therefore not cross-resistant with other commercial fungicides, which makes Initium an ideal tool for managing fungal resistance in specialty crops. The classification has been shared with and accepted by the Fungicide Resistance Action Committee (FRAC).

“This discovery marks a significant scientific breakthrough for BASF’s research and development team. It is exciting for our team to have developed a molecule with such a novel mode of action,” said Philip Lane, Vice President Global Research Fungicides. “This will help specialty crop growers worldwide to better manage plant diseases. We remain committed to developing and delivering additional innovations in fungicides.” 

Initium is a highly selective fungicide that reliably and flexibly controls a range of downy mildews and late blights. Its rainfastness and ability to redistribute on growing leaves keep crops protected and healthy for longer, allowing them to develop to their full potential. Initium-based products were first registered in 2010 and, most recently in December 2013, received approval for grapes in India. As part of BASF’s commitment to delivering solutions for specialty crop markets worldwide, Initium-based products are currently available for more than 30 specialty crops, including grapes, potatoes, tomatoes, lettuce and other vegetables, in more than 50 countries.
