Roy’s soilborne inoculum work
Roy spent plenty of time in the laboratory quantifying Fusarium oxysporum f. sp. vasinfectum (Fov) DNA from field soil, and some of his work is now reported in a Plant Disease publication: https://doi.org/10.1094/PDIS-08-21-1664-RE The work’s objective was to describe spatial variability in Fov inoculum density in the field, because that variation is hypothesized to affect…

Roy’s Citrus Greening Research
I recently started research focusing on citrus greening and inoculum density. In the left picture, Candidatus Liberibacter asiaticus (CLas), the presumed causal agent of citrus greening, was first detected 6 years ago. The right picture shows a more recent infection first detected in 2020. The damage from a long-term infection is apparent between the two pictures…

Roy’s Sampling at the Citrus Center
I went to the Citrus Center in Weslaco, Texas, to set up data loggers and collect samples. Data loggers will be used to record soil and canopy temperatures. The data from these loggers will be interesting as they were set in place shortly before Winter Storm Uri, which is likely to have affected citrus trees.

Roy’s LARS work
Roy’s collaboration with other researchers using unmanned aerial systems led to an application recently published in Agronomy. doi: 10.3390/agronomy10050633 Roy set out to make use of available low-altitude remote sensing data. Available data are often more useful than unavailable data, in practice. Work led us to recognize that data generated through LARS are different from…
