Carolina Bertuzzi, a DSc student from Tessman’s lab (Universidade Estadual de Maringá), is joining the Del Ponte lab where she will stay untill completion of the studies to decipher the variability of Fusarium graminearum population causing head blight of wheat and barley in Paraná State.

It is that time of year that we look back and realized how much has been accomplished in the last year - and a lot went on in 2017! It was the fourth one here at Viçosa and a very busy for a growing Lab.

Excited to announce our first manuscript available as preprint in bioRxiv accompanied by a research compendium which provides access to the raw data and the R scripts for the analysis.

This was the big last project I needed to finish before 2018 kicks the door. Now that the semester ended (and students and secretary have gone and phone does not ring), I was able to have some fun during several good hours…

The second thesis defense of the year was presented by Caroline Ávila (on the right at the photo), one of the students involved in the Fusarium rice project who focused her work on the diversity of the Fusarium incarnatum-equiseti species complex infecting rice in Brazil.

Another publication of the Lab goes fully reproducible with the manuscript full text, raw data and the R codes made available. Since the first reproducible report I made using R Markdown and deployed later last year, I was able to improve the interface of the HTML report which is now multiple-page.

Data and R codes to reproduce the analysis performed in a manuscript reporting estimates of yield loss and sclerotia production as a function of white mold incidence.

From August 25 and 26 we had our third one-day Fusarium rice project workshop at Lavras, MG. These workshops occur every six months, alternating between UFV and UFLA, and aim at updating and planning research activities, especially targeting planning of activities of the doctoral and MSc research.

Research efforts on soybean white mold increased in the last decade in Brazil, especially focusing on disease control methods. However, quantitative summaries of soybean yield and fungal sclerotia (a fungal sexual structure) due to the disease were not available. We used meta-analysis to obtain estimates of yield loss and sclerotia production with data from four-year field trials.

Prior to my move to Viçosa, back in 2012, I began interacting with research groups (leaders) of the Pharmacy (Prof. Fuentefria) and Chemistry (Prof. Schrekker) Departments at UFRGS. I was co-advising a doctoral student (Aicha Ribas) on her study on the search for alternatives to standard chemical fungicides for plant disease control.

Our recent article demonstrates the combined use of digital analysis and various spatial pattern techniques to study lesion distribution at the leaf scale. The study was conducted by my former M.Sc. student, André Aguiar Schwanck, currently a doctorate student at Toulouse France.

In early April, we attended the 5th International Symposium on Fusarium head blight and the 2nd International Workshop on wheat blast joint meeting at the beautiful Costão do Santinho resort hotel in Florianópolis, Brazil. It was a truly international meeting with over 150 delegates from more than 30 countries around the world, who works with head blight and/or wheat blast.

This past week (February 23 2016) we had our first thesis defense in the Lab two years after moving the Lab from UFRGS to UFV. Previously, I had advised eight M.Sc. students when I was a faculty member in southern Brazil.

Results from a long-term research collaboration with Tessmann Lab (UEM) and Ward Lab (USDA) on the diversity of FGSC species occurring at different maize parts (ear, stalks and stubbles) were published Online Early this December in Plant Pathology.

Recently, we collaborated with a research conducted by colleagues from Argentina (Prof. Stenglein Lab) and Uruguay (Dr. Pan Lab) to decipher the diversity and population structure of the F. graminearum species complex affecting barley in the main producing-regions in South America.

This week, from 9-11 November 2015, I taught my Epidemiology course for the students enrolled in the semi-present master degree in plant health protection (Defesa Sanitária Vegetal). This was the second of the three meetings of this group, this time held here at the Universidade Federal de Viçosa.

In early September 2015 I was invited by colleagues of the Graduate Program in Ecology of UFV to give a talk about modeling and risk assessment of plant diseases at their research seminar. For that audience, I briefly presented some concepts on plant diseases and epidemics, disease models, risk assessment and prediction and approaches to develop and test the models.
