Blight research: GM potato, IPM can reduce environmental impact of potato production by over 95%

Researchers with Teagasc in Ireland have concluded their field study which investigated both the environmental and agronomic impact of a GM potato variety genetically engineered to resist late blight disease, caused by Phytophthora infestans. Potato late blight can rapidly destroy potato crops with growers commonly having to resort to spraying their crops with fungicides on a near weekly basis. Teagasc research indicates that combining a cisgenic blight resistant potato with advanced Integrated management systems can reduce the environmental impact of potato production by over 95%. As part of the EU funded ‘AMIGA’ project and in collaboration with Wageningen University, Teagasc looked at issues such as the efficacy of disease control and the resulting environmental impact during cultivation of a susceptible potato variety (Désirée) and two different resistant potato varieties: Sarpo Mira, developed through conventional breeding, and a resistant version of the Désirée which received a resistance gene from a wild potato through cisgenesis.
