Using the Forecasting System to Assess the Risk of Head Scab

Pierce 1By: Pierce Paul, OSU Extension

The head scab risk tool can be used to assess the risk of head scab and to help guide fungicide application decisions. Here are a few guidelines for using the system and interpret the output:

1.) Go to the website at www.wheatscab.psu.edu. You will see a map of the United States with some states in green, yellow, red, or gray. Continue reading

It’s important to correctly identify winter wheat growth stages to enhance management decisions, avoiding damage to the crop and unwarranted or ineffective applications. Remember, the exact growth stage cannot be determined by just looking at the height of the crop or based on calendar dates. Continue reading

Winter Wheat Stand Evaluation

Evaluating wheat standBy:  Laura Lindsey

Between planting in the fall and Feekes 4 growth stage (beginning of erect growth) in the spring, winter wheat is vulnerable to environmental stress such as saturated soils and freeze-thaw cycles that cause soil heaving. All of which may lead to substantial stand reduction, and consequently, low grain yield. However, a stand that looks thin in the spring does not always correspond to lower grain yield. Rather than relying on a visual assessment, we suggest counting the number of wheat stems or using the mobile phone app (Canopeo) to estimate the wheat grain yield. Continue reading
