Excitingly presented my study on spatial distribution and population dynamics of nematodes influenced by environmental variables in the State of Goiás. Revealing insights into the intricate interaction between soil conditions and nematode populations. #Epidemiology #Modeling

@MahDuffeck Well done! Congratulations.

The 2026 season has officially started for our lab

[Felipe Dalla Lana @felipedallalana]

The Rice Pathology lab visited the Gueydan High School's senior class to share how science and technology shape rice production. We also share insights of what we do in our lab, Rice Research Station, and @LSUAgCenter

“While low-tolerance [soybean] cultivars benefit most from chemical interventions, high-tolerance cultivars offer a sustainable alternative by reducing reliance on fungicides, minimizing environmental impact, and mitigating economic risks associated with fungicide resistance and reduced efficacy.”

From the article Economic returns on fungicide use across soybean cultivars with varying tolerance to target spot (Corynespora cassiicola) https://t.co/u7WzJMQD3p by @tomazrg Claudia Vieira Godoy & @edelponte

@CropNetwork Thank you so much!
The target spot is an important disease in Brazil. Understanding the economic damage caused by the disease is essential.

🚨Check it out ! 🚨

Our preprint, "Economic returns on fungicide use across soybean cultivars with varying tolerance to target spot", is already online.

Thanks,@edelponte and Claudia Godoy!

This week, I had an amazing experience at the Mentee Program meeting with Bayer in Paulínia, SP!

It was a great opportunity to connect and learn from Bayer's researchers. Many thanks to Rayssa for the guidance and opportunities, and to Bayer for making this possible!

Check it out ! #TargetSpot 🥳

Our preprint ,"Performance of dual and triple fungicide premixes for the control of soybean target spot after seven years of use", is already online.

Thanks, @edelponte !

The spatial analysis by distance indices (SADIE) quantify spatial patterns by calculating the distance to regularity. It has found use in #plantpathology and modifications were proposed by @TheLarryMadden and @XiangmingXu1 . This animation helps to illustrate the concept.

For repetitive tasks, people suggest writing a function. I'm loving embedding those functions into R Shiny apps to speed up my analyses and reports of both individual (anova) and multi-location (meta-analysis) fungicide trials! #PlantDisease #DataScience #RStats #ShinyApps

Check out my newest R Shiny project. An interactive photo gallery of high quality images of plant rusts taken by Prof. @PretoriusZak and organized by @LandbouLisa and @B12272396Willem. Data hosted in google sheets and images in @OSFramework

@Mariela24fdez Hello Mariela. Thank you so much !

What is the profitability of fungicide application on resistant wheat varieties with high or low yield levels?

A simulation with parameter ranges developed has made it possible to visualize the break-even probabilities between income and cost.
