On April 13, Doug Cooper , Extension communications specialist, interviewed Iowa State University Extension climatologist Elwynn Taylor, integrated pest management specialist Rich Pope and corn agronomist Roger Elmore for the weekly crops and weather update.
Extension climatologist Elwynn Taylor tells Cooper that La Niña appears to be making a comeback, maybe. The Southern Oscillation Index (SOI) has gained back some of its strength the past week or so.
Rich Pope says winter annual weeds need to be scouted in some parts of the state.
Extension corn agronomist Roger Elmore reports that farmers are starting to express concerns that wet weather may delay spring planting again this year. Last year’s yields were surprisingly good – thanks to a major improvement in weather conditions in the middle of August.
