Root rot seedling disease
scouted Aug. 7, 2023
- Scientific Name
- Rhizoctonia sp., Fusarium sp.
- Background
- Soybeans in Richmond county, variety AG59XFP, were scouted and observed 100% of the field was affected. This site has had soybean production problems for three years and the land has been farmed for 20 years. The majority of the seedling population failed to grow and the plants do not germinate well. Rainfall has been low, but still sufficient for production. The site is low and dry.
- Conclusion
- The issues was identified as Root rot seedling disease. The is disease is caused by Rhizoctonia sp. and Fusarium sp. Planting soybeans in optimal environmental conditions that favor quick stand establishment of the seedling will reduce plant stress and mitigate disease risk. Improving soil drainage may also reduce stress and risk of infection. Optimal seeding rates and planting depths may also increase the rate of stand establishment to reduce the susceptibility of seedlings to various diseases. Crop rotation can help in some situations; however, this may not always be effective due to the wide host range of Fusarium and Rhizoctonia species
