The World Potato Congress is very pleased to present its next webinar on Wednesday, March 31, 2021 with Albert Schirring, Strategy Lead Vegetables & Potato, Bayer AG.

Presentation Outline

Late blight caused by the fungal like pathogen Phytophthora infestans is a challenging pathogen to control. One hundred-seventy-five years after the devastating outbreaks in Ireland, late blight still causes worldwide economic losses. Key lessons from the past provide us the basis for an integrated approach to support small and large scale farmers around the world in controlling the disease to secure their income and sustain national food security.

The key principles of robust late blight management strategies will be discussed. It is based on the control of primary inoculum, the adoption of tolerant varieties with stacked resistance genes, the implementation of an optimized fungicide strategy according to crop growth stages in which optimal application timings are digital enabled.

Special attention will be given on the global population dynamics of the late blight pathogen to improve fungicide resistance management strategies, building on the outcomes of research networks in Europe (Euroblight), USA (USAblight), Latam (Tizon Latino) and APAC. Overall there are exciting new outlooks for production concepts reducing the impact of Phytophthora on productivity to deliver on the UN sustainability goals to benefit all foods system participants.

Albert Schirring, born at Emmen (Netherlands), studied agronomy at the Agricultural High School in Groningen from 1977-1981. He finished the Wageningen University in 1989 and graduated on Plant Pathology majoring on fungicide resistance management and control strategies for soil born pathogens.
