For many parts of Iowa, 2023 is the third consecutive year of drought conditions. This has made establishing cover crops challenging. Drought conditions make overseeding cover crops into standing corn and soybean less successful because of a lack of rainfall to get seeds to germinate. Advice to...

After about a month of minimal rainfall across the state, some much welcomed rain fell over the weekend and on Monday, September 11. The couple of hot weeks and dry conditions in August really pushed crops along across the state, even causing some to reach maturity prematurely. Silage harvest is...

Field crop health matters throughout the entire growing season. The types of diseases on crops depend on the point in the growing season and the environmental conditions. Many later-season diseases result from soilborne pathogens over which in-season fungicide applications have no control. Most...

While it is no secret soybean disease has been more prevalent in soybean fields in southwest Iowa this month. However, not all the problems in soybeans can be attributed to disease incidence. I have received and observed an unusual pest this month, Dectes stem borer! Look at your soybeans...

I received several questions about blister beetles in alfalfa hay over the weekend. I thought it might be helpful to review what they look like and provide a few management tactics to minimize the negative effects for animals.

There are at least four species in Iowa, including a) black, b...

We have now reached the critical period for maximizing yield for both corn and soybeans. I will focus on soybeans for this blog and how soil moisture affects moisture stress in beans and soybean yield. With recent rains across a sizable portion of Iowa in mid-July, soil moisture profiles changed...

Blister beetles are an occasional late-summer problem in Iowa alfalfa fields. The beetles feed on alfalfa and soybean foliage, but leaf loss is not of economic importance. The bigger concern with blister beetles is their toxicity to livestock when accidentally consumed in feed. The beetles...

The smoke from the 2023 Canada wildfires was noticeable in Iowa, especially on June 28 and 29, and concerns about impacts on crop productivity were voiced. The smoke from the California wildfires (August 2021) was evident in Iowa too, however, this did not have a negative effect on crop...
