Wheat is starting to head out across the central and northern Indiana, with flowering not too far behind. Our plots in southern Indiana hit early anthesis (flowering) last week and we put out our Feekes 10.5.1 fungicide trials out at Southwest PAC, Vincennes, IN.
Rainy, wet conditions will favor many fungal diseases in wheat. Already our southern neighbors have started reporting multiple diseases in wheat.
Wheat harvest has begun in Southern Indiana. Fusarium head blight (FHB) or scab is one of the most important diseases of wheat and most challenging to prevent. In addition, FHB infection can cause the production of a mycotoxin called deoxynivalenol (DON or vomitoxin). The environmental conditions have been extremely conducive to FHB development and it is not surprising that I have started to receive reports about issues with FHB and DON contamination. Our research sites in both West Lafayette and Vincennes have high levels of FHB develop in our non-treated susceptible variety checks and initial DON testing was at 7 ppm. Fusarium head blight management is difficult and requires an integrated approach. This includes selection of varieties with moderate resistance and timely fungicide application at flowering. We are now past implementing either of these management options, but these are important to remember for next year. In addition, it will be[Read More…]
Even though rainy conditions continue to slow planting across the state, we need to keep an eye on winter wheat. These wet conditions will favor many fungal diseases.
