The 2018 Iowa harvest is posing many challenges. Higher than average harvest losses are likely due to excessive soybean shatter, flooded and wet field conditions, and lodged corn and beans.
Harvest losses can only be managed if you know where and why they are occurring. Measuring harvest...
With all eyes now on harvested grain quality and scouting for mycotoxins as a result of ear rot, it's important that producers and agronomists have access to all the information possible, on whichever medium they prefer to use.
An application is available on both Android and iOS that can...

It's Labor Day weekend, that means it's time for me to see what's happening at the first three Palmer amaranth infestations in western Iowa. The infestations (Harrison, Fremont, and Page Counties) were first reported in 2013. Harrison County had two fields (approximately 50 acres) with...
Late season weed escapes, off-target herbicide movement, sightings of soybean aphids, and a little bit of frogeye leaf spot were some of the common issues that Iowa State University Extension and Outreach field agronomists saw in...
Gray leaf spot, spotting of soybean aphids, and off-target herbicide movement seem to be common and big issues that Iowa State University Extension and Outreach field agronomists saw across the state this past week. Read on for more...
Mile-a-minute weed (Persicaria perfoliata) is an invasive species in the Polygonaceae (smartweed) family that is native to Asia. It is believed to have been introduced to the United States in the late 1800’s and early 1900’s, but the initial introductions failed to form permanent...
This past week brought drier conditions across the state. Northern Iowa appreciated the chance to dry out some, but parts of southern Iowa could really benefit from some much needed rain. Check out what Iowa State University Extension and Outreach ...
Humans are making more sound, and it can interfere with animals finding mates, food and other essential behaviors. Most of the research showing impacts of human-generated sound is largely focused on vertebrates. Biologists at Mississippi State University were curious about sound potentially...
The warm conditions continue to push crops along. Across the state we are approximately...
Strong storms rolled across the state again bringing more heavy rain and even some damaging wind to areas. Despite the flooding in some areas and drought in the southern part of the state, 78% of the corn crop and 76% of the soybean crop was rated in the good to excellent condition based on...
The saga continues with areas of northern Iowa receiving too much rain while southern Iowa continues to be on the drier side. Rainfall totals across the state ranged anywhere from nearly 10 inches in NW Iowa to less than half an inch in parts of southern Iowa. According to...
Parts of Iowa received some much needed rainfall last week, but unfortunately for some areas the storms that rolled through also brought along hail and caused flooding. Overall, crops are looking good across the...
This week, I’ve had a number of people tell me they spotted Japanese beetle. I was initially surprised, because I track degree days to predict adult emergence every summer and it seemed a bit early. According to the ISU Agronomy Mesonet, adults could be emerging...
While parts of Iowa are too wet and have experienced hail, wind, and flooding over the past week other parts of the state could desperately benefit from some rainfall. Despite the drastic differences in moisture levels across the state, according to...

Despite the late start to #Plant18, especially in northern Iowa, planting has nearly wrapped up with corn and soybeans across the state. According to Monday’...
The Iowa State University Integrated Pest Management (IPM) program is proud to announce the creation of its own YouTube Channel through which to promote the efforts of Iowa State University scientists and researchers in providing means-tested crop and pest management solutions to stakeholders in...
While #Plant18 has basically wrapped up in the southern part of the state for corn and soybeans are about three-fourths planted, #Plant18 has been much slower in the northern part of the state. According to...
