Tom Petty said he was “learning to fly, but I ain’t got wings.” The last two weeks have made me think about flies way too much. The black flies, sometimes called buffalo gnats, have been terrible and making it hard to be outside. These small flies (1/4" in length) are black or gray and somewhat...

True armyworm is a migratory pest that arrives in Iowa from southern states and lays eggs on living tissue. Adult females are attracted to fields with green plants, particularly weedy grasses or living cover crops. These plants serve as initial feeding sites for larvae. When these original host...

Cool conditions during planting season increase the potential for herbicide injury to seedlings due to slow emergence and reduced ability of the crop to metabolize herbicides. While herbicides may be responsible for emergence issues, most problems that have been brought to our attention seem to...

Over the weekend, someone let me know they saw a western corn rootworm adult. Remember this pest overwinters as an egg that hatches in June! They get confused with closely-related species every spring: striped cucumber beetle. Striped and spotted cucumber beetles overwinter as adults and become...

Every year is different. This year’s weather from January 1 to April 25 was cold and wet; a stark contrast to last year’s weather. While we know the differences in weather conditions every year, we do not know the implications on soil water and N at planting time. Field operations have just...

It has been a slow start to #Plant18 in Iowa. The cooler and wet weather has kept many farmers out of the fields despite the fact that it is getting to be the end of April. Spring finally seems to have arrived (or at least for parts of Iowa), and with that farmers are not wasting anytime getting...

This spring has already brought on concerns about poor weather resulting in delays on corn planting. At this point in time, there is still time. It is highly important to remain patient and wait for the right corn planting conditions. Planting into marginal conditions can result in problems all...

Green cover crop fields are slowly starting to appear across the state. Despite the recent snow that fell across the state, #plant18 is right around the corner. Farmers should have a game plan in place for how they plan to terminate their overwintering cover crop. Killing cover crops with a...
