This year, given the widespread pre-harvest hail in Nebraska wheat, it's crucial to take measures that will minimize the risk of occurrence of wheat streak mosaic in next year’s winter wheat crop.
With shorter and thinner wheat this year, weed emergence and growth will be accelerated, making it essential to closely watch for weed developments and spray at the proper time noted on the label to achieve maximum control.

Volunteer wheat can provide the summer "green bridge" for the disease wheat streak mosaic and other virus diseases, as well as soil water loss that could translate into a substantial decrease in yields the following year.
Frogeye leaf spot — which will likely begin appearing in Nebraska soybeans within the next few weeks — can cause significant yield loss, but there are effective management options available.
White-margined burrower bugs will move to nearby crop plants to feed when their preferred host plants are terminated, but they typically don't cause economic damage to crops.
Irrigation Management

While a recent study revealed that irrigators tend to overwater on wetter years, extension experts recommend data-driven decisions for optimizing yields, saving water and lowering cost of production.

As of June 12, the majority of corn and soybean crops had emerged, with conditions rating 88% fair to excellent for corn and 90% fair to excellent for soybean.
A variety of resources are available to help Nebraska producers affected by recent hail events with assessing damage, recovery and replant options, as well as crop insurance considerations.
