Agricultural experts in Illinois say they're unsure how this winter's mild weather will affect the planting and growing season.

Insects have been one concern for farmers. University of Illinois professor Mike Gray says many insects that impact crops don't spend winters in the area, so the mild weather wouldn't affect them.

Gray says the mild weather may lead some insects to appear earlier but he says that doesn't mean there will be more insects. He says that's because the number of adult insects last year was "relatively low." Gray is more concerned about spring weather.

The weather has been a bonus for cattle producers. Knox County Cattlemen's Association President Matt Johnson says the weather has let him use less feed and do field work.
