#IEW13 day two starting with plant disease modelling Alexey Mikaberidze

Group photo of the 13th International Epidemiology Workshop held in Foz do Iguaçu Brazil 9-12 April 2024. Privileged to have been the leading organizer. Long live Epidemiology! #IEW13

José González-Acuña speaks about using environmental variables to predict frogeye leaf spot in #soybean caused by fungal pathogen Cercospora sojina using logistic regression #iew13

José Maurício Fernandes speaks about mitigating impact of drought and wheat blast on rainfed wheat in Brazilian Cerrado via adjusting sowing dates and varieties #iew13

Adam Sparks CCDM gives overview of useful resources for modeling climate change effects on plant diseases. why don't we share code in plant pathology publications? extremely useful tools to get climate data in Julia, Python and R #iew13

Carlos Gongora-Canul Purdue Botany and Plant Pathology - GSO insights from comparative epidemiology of tar spot in corn caused by fungus Phyllachora maydis: endemic in South America, emerging in North America #iew13

Belachew Asalf speaking about effect of cover crops & green manuring on Sclerotinia white rot in carrot; many other pathogens cause post-harvest diseases in carrots #iew13

Ayalsew Zerihun presents fungicide resistance modeling: "Do Growers Using Solo Fungicides Affect the Durability of Disease Control of Growers Using Mixtures and Alternations? The Case of Spot-Form Net Blotch in Western Australia" doi.org/10.1094/PHYTO-… Joe Helps CCDM #iew13

Arne Stensvand's talk: Botrytis in strawberry serious problem in Norway exacerbated by fungicide resistance; multiresistance 96% in 2018; fewer applications -> less resistance #iew13

Sara Thomas-Sharma speaks about using epidemiological knowledge to improve management of Cercospora leaf blight in soybean #iew13

David Gadoury memorable overview on ultraviolet light to suppress plant pathogens: poison is in the dose; access to target is crucial; UV activity only eradicative; recontamination and interplot interference possible #iew13

Renato Bassanezi speaks about epidemiology-based management strategies for citrus Huanglongbing: regional disease management effective but hard to implement Fundecitrus #iew13

#IEW13 extremely grateful for this opportunity to present our work on modeling economic costs of fungicide resistance evolution; thanks to fantastic collaborators Prateek Verma Chaitanya Gokhale Maria BR pre-print here shorturl.at/bjpPV

We had a great #IEW13 last week in Brazil. For those interested in signing up to receive messages about plant disease epidemiology activities in the future, please sign up here: docs.google.com/spreadsheets/d… Emerson Del Ponte Larry Madden

Nice work by Alexey Mikaberidze on how they've been assessing the economics of fungicide use in wheat fields in Europe, plus a VERY cool and thought provoking work on how some leaves may function as super spreaders for outbreak by hosting an abundance of pycnidia #IEW13 #sketchnotes

Remember Alchemy in 2007? Brown rust ran riot following a winter/spring that was 2-4 degrees above average. Crusoe in Cambridgeshire this week - its early for Brown rust, but no surprise - Oct, Dec, Feb and March all unseasonably mild. ADAS ADAS Boxworth

Genome-wide association study identifies markers and candidate genes affecting leaf-level tolerance to the #wheat pathogen #Zymoseptoria tritici our preprint shorturl.at/7wSTy great collaboration with Bruce McDonald Lukas Kronenberg #ZymoPapers

Our paper "A Genome-Wide Association Study Identifies Markers and Candidate Genes Affecting Tolerance to the #wheat Pathogen Zymoseptoria tritici" published doi.org/10.1094/MPMI-0…; fantastic collab Bruce McDonald, Lukas Kronenberg #ZymoPapers SAPD at Reading Uni ETH Zurich John Innes Centre
