Several soybean fields scouted in a number of Eastern counties have plants dying or dropping leaves prematurely. While the majority of these fields have drought stress causing early senescence, a few fields have also stem canker developing
Sclerotinia Concerns in Sunflower
Sclerotinia diseases are a concern in sunflowers, because the fungus can infect the plant through the root, mid-stalk or the head. Wet weather and cool temperatures two-to-three weeks prior to and during flowering favor disease development.

Drought Conditions May Increase Soybean Cyst Nematode Population in Soil
Moisture stress coupled with above-normal temperatures have been linked with increased soybean cyst nematode populations in the soil. In order to keep populations in the soil below the yield-reducing levels, there are a few management practices which can be used.
Stripe Rust Starting To Develop in Winter Wheat
Stripe rust was found in a few winter wheat fields scouted this week. The presence of a few plants with stripe rust indicates there is inoculum of this pathogen in the state.
Use Fusarium Head Blight Risk Prediction Tools for Better Disease Management
Winter wheat has reached the flowering growth stage, which is a time of high risk for Fusarium head blight. By using disease prediction tools correctly, a producer can protect wheat from infection by applying a timely fungicide when the tools show moderate to high risk.
