Seeing disease symptoms in your soybean fields? Bring us your sick soybeans at Farm Science Review!
During Farm Science Review, September 22–24, the OSU Soybean Pathology and Nematology team will have a sample drop off box at the AgCrops Team Tent. We are especially interested in soybean plants showing symptoms that may be associated with sudden death syndrome (SDS) or red crown rot (RCR).
How to bring a sample:
- Collect several symptomatic plants, preferably still alive and showing moderate symptoms.
- Dig up the entire plant and keep the roots and lower stem intact.
- Place plants in a plastic bag, remove as much air as possible, and keep them away from heat and direct sunlight. Do not use moist paper towels.
- Print and complete one submission form for each sample and bring it with the plants.
Then simply drop your samples off at the AgCrops Team Tent (on the east end of Friday Ave). We will bring them back to the laboratory for diagnosis to determine whether the symptoms are associated with SDS, RCR, both, or another disease.
