Illinois: Late start, but good weather has both crops emerging and developing quickly, along with weeds.

Indiana: Planting ahead of five-year average, but strong weed control program needed.

Iowa: A mixed bag of planting dates, cool/wet soil issues, northern areas lagging behind, but recent warmth boosting planting and emergence.

Michigan: Planting on track with five-year average, but cooler temperatures have slowed germination and emergence.

Minnesota: Big mid-April blizzard and continued cold soils and rains slowed planting, but recent warmth finally getting seed in the ground. Nitrogen needs must be watched.

Ohio: Wet weather has farmers behind in both corn and soybean planting, with big temptations to try and plant wet fields.

South Dakota: Despite cool, wet April, recent warmth has planting near five-year average. Next up, weeds and monitoring nitrogen.

Wisconsin: Rains have kept planting minimal in the central part of the state, and lower than average temperatures are keeping weeds at bay, until the warmth hits.
