Study offers new method of identifying sweet corn hybrids for increased yield and profit.Corn hybrids with improved tolerance to crowding stress, grown at higher plant populations than their predecessors, have been a driver of rising field corn yields in recent decades.Large differences in crowding stress tolerance (CST) recently reported among popular sweet corn processing hybrids has growers and processors wondering if newly emerging hybrids also offer improved CST.For more information, click here.
Food Safety Considerations for Food Crops.According to the Illinois State Climatologist, after a record-setting June, as well as a wet May beforehand and a wet July so far, we are seeing the agricultural impacts of the wet growing season.Right now, the state-wide July precipitation in Illinois is at 3.1 inches.That is about 50% above the long-term average for this time in the month.
With all of this precipitation, what are the issues facing growers in light of our current growing conditions?Flooding is defined by the Food and Drug Administration (FDA) "flowing or overflowing of a field with water outside a grower's control." Due to microbial and other concerns, produce cannot be harvested and sold into the public food supply once it contacts flood water.The FDA publication, Guidance for Industry:Evaluating the Safety of Flood-affected Food Crops for Human Consumption, provides guidance to growers on how to evaluate the safety of flood-affected food crops for human consumption including:
- safety of food crops when flood waters contacted the edible portions of the crops;
- safety of food crops when flood waters did NOT contact the edible portions of the crops;
- assessment of flood-affected fields before replanting;and
- additional controls to avoid cross-contamination after flooding.
