Throughout my PhD work, it became obvious that the challenges of spinach downy mildew were most heavily impacting organic growers. They were unable to rely on conventional synthetic pesticides that were able to suitably control disease in the conventional crop, and had to rely on resistance to control the disease. I wanted to see if any biofungicide had effect on the disease.
I was part of an upcoming book chapter on the threat of climate change for pathogens, and all I could think of was the idea of pathogens on the horizon. I painted a watercolor illustration for the book chapter, maybe it’ll be used as the book cover! The painting draws inspiration from Outrun/vaporwave sort of art that became popular in the late 2010’s, although the color palette is wayyyy off, it should be neon blue and pink!

During my master’s degree, we set out a lot of projects (I had originally intended for my master’s to be a PhD…but thats a story for another time). So I ended up having a ton of different interconnected projects running with Doug Gubler looking at different aspects of grape powdery mildew biology and epidemiology. While we knew that there were differences in how grape varieties and cultivars reacted to powdery mildew, we couldn’t find a great resource that looked at the cultivars grown in California in the present.
For an ordinary least squares regression model, the coefficient of determination R2 describes the proportion (or percentage) of variance of the response variable explained by the model, and is a widely-accepted summary measure of predictive power. A …
Plant pathology must address a number of challenges, most of which are characterized by complexity. Network analysis offers useful tools for addressing complex systems and an opportunity for synthesis within plant pathology and between it and …
Phylogenetic relationships between thirteen species of downy mildew and 103 species of *Phytophthora* (plant-pathogenic oomycetes) were investigated with two nuclear and four mitochondrial loci, using several likelihood-based approaches. Three …
Seedborne pathogens and pests limit production in many agricultural systems. Quarantine programs help reduce the introduction of exotic pathogens into a country, but few regulations directly apply to reducing the re-introduction and spread of …
Spinach downy mildew, caused by the biotrophic oomycete *Peronospora effusa*, is an economically important disease that is found in all spinach growing regions of the US. To effectively predict disease risk we need to understand the response of *P. …
Laurel wilt kills members of the Lauraceae plant family in the southeastern United States. It is caused by *Raffaelea lauricola* T.C. Harr., Fraedrich and Aghayeva, a nutritional fungal symbiont of an invasive Asian ambrosia beetle, *Xyleborus …
