The official first report of red crown rot of soybean in Indiana is now out, in collaboration w/@PurduePPDL we have confirmed it in four counties. Be on the lookout during the 2024 season. Indiana Soybean Alliance Purdue BPP Purdue Extension | Plant Disease apsjournals.apsnet.org/doi/10.1094/PD…

Our 2024 field season has kicked off. Soybeans planted yesterday and started corn today. Research evaluating planting dates and seed treatments on soilborne pathogens. What a team!! Purdue Agriculture Purdue BPP Purdue Extension

We are just graduate students, please help us 😊 #PurdueDayofGiving

Time to setup and spray USWBSI supported wheat scab UFT and IM fungicide trials at Southwest Purdue Ag Center Purdue Agriculture Purdue Extension Purdue BPP

I am pleased to share that my latest research article about Tar Spot colonization in maize leaves has been published in Phytopathology! Anjali Iyer-Pascuzzi Helm Lab John Bonkowski Camila Rocco da Silva Austin McCoy Martin Chilvers Darcy Telenko apsjournals.apsnet.org/doi/full/10.10…

Come to see my poster number #266 on Cercospora spp. causing CLB of soybean resistant to QoI fungicides I will be presenting on July 30th from 4:00 to 4:45 PM #PlantHealth2024

With high tar spot severity, ground-applied fungicide resulted in a partial net-return ranging from $11.9 loss to $83.9/A gain. With low tar spot severity, the partial net-return ranged from a $46.5 loss to a $5.8/A loss. Yield data and fungicide efficacy tar spot research

“Combined cultural practices and resistant variety selection can likely provide sufficient [white mold] control for most organic soybean systems...” From the PhytoFrontiers™ article doi.org/10.1094/PHYTOF… by Camila Rocco da Silva Erin Silva Darcy Telenko Damon L. Smith +more

We have officially confirmed tar spot in all 92 counties in Indiana for the first time in a single year. There are differences across the state on yield impacts, from little to no loss up to reports of 100 bu/A. It will be a busy winter discussing future management options.

We are still looking for a new team member to help us operate all our fun field equipment in our research program. careers.purdue.edu/job/Research-A…

I am still looking for a field technician to join our team - here's the new application link if you know of anyone that might be interested. careers.purdue.edu/job/Associate-… Purdue BPP Purdue Agriculture Purdue Agronomy Extension

Another successful day planting both soybean and corn trials at Pinney PAC for tar spot and SDS research Purdue Agriculture Purdue Extension Purdue BPP

I found tar spot in our research plots yesterday and have turned on the map for 2025 season. See link on what that means for corn and making an informed fungicide decision on your farm indianafieldcroppathology.com/tar-spot-what-… Dan Quinn Purdue BPP Purdue Extension Damon L. Smith

Additional information, especially now that tar spot is active for 2025.

These are not tar spots but insect frass, if you are unsure please submit to our diagnostic labs (images can also be sent, but be prepared as we may ask for the leaf especially for these early scouting efforts) ag.purdue.edu/department/btn… Damon L. Smith Martin Chilvers Alison Robertson

Reposting my Extension article from last week and some images of tar spot to help distinguish from other things that mimic it. indianafieldcroppathology.com/tar-spot-what-… Purdue Extension Damon L. Smith Alison Robertson Martin Chilvers Tamra Jackson-Ziems

Looking forward to talking about my PhD research in today’s poster session! cCome swing by poster P-097 to talk tar spot, effect of fungicide, and application timing #PlantHealth2025
