Seedling disease is running rampant across Illinois soybeans. Many producers are wondering why. Afterall, you used a fungicide treatment. Well, there are many things that could be at play. I describe these in this weeks Field Crop Disease Blog (click here). Remember to sign up for updates!…
With the storm that moved through the state the past week, it is not surprising that we are seeing more seedling diseases in soybeans. In many cases Rhizoctonia has been identified as the causative organism, alone or in combination with other soil issues such as compaction. Rhizoctonia is one of the most common and problematic seedling issues for soybean producers in Illinois, and can cause significant yield losses due to stand reduction and reduced plant growth. …
Now is the time that seedling diseases of soybeans will start to be apparent. Indeed, we have started to see more images of soybeans that may have symptoms of seedling disease. However, it is important to understand that seedling diseases are complex, and a simple picture often is not sufficient to adequately diagnose the issue. I wrote a more extensive of seedling diseases of soybean on the Illinois Field Crop Disease Blog, which can be accessed here…
The Crop Protection Network is a free, online resource for producers and those in the agronomic community interested in diseases of field crops and their management. Recently, CPN started adding resources to the site to include diseases of small grains such as wheat. As part of this effort, we published a publication on how to optimize fungicide applications for Fusarium Head Blight management. The publication can be accessed for free at the CPN library …
Well, it is that time of year where we start to see issues developing in the field. Questions such as, “What happened?” and “Why me?” will become more common. The key to managing diseases is proper diagnosis, and this starts in the field. In my recent post on the Field Crop Disease Blog, I provide several tips for diagnosing issues in the field, and distinguishing disease related problems from abiotic issues. Check out the post,…
With the recent rain blast and rain forecast in the next week, coupled with the wheat crop starting to move into flowering within the next 7-14 days, it is important to start thinking about Fusarium head blight risk. I recently wrote an expanded article on the use of the FHB prediction tool that can be found by clicking here.
Some early flowering varieties will likely flower by the weekend. Most varieties are near flag leaf and will require another 7 –…
This past week we spent a few days surveying wheat fields throughout the state in order to see how the crop is progressing as well as better understand what disease related issues we may be experiencing. Most of the crop was near flag leaf emergence (Feekes growth stage 8/9) with a few fields near boot in locations further south. The good news is that of the 26 fields we looked at, none had any stripe rust,…

I received notice of stripe rust in S. Illinois today. Stripe rust is an important disease affecting wheat. Please find an article on this disease and management by clicking here.
If you locate stripe rust in your field please tweet a picture to me (@ILplantdoc) or email (nathank@illinois.edu) with the wheat variety, growth stage, and approximate percent of field infected. This information will be useful to IL wheat producers this year and in upcoming seasons.…
