As the growing season winds down, ISU Extension field agronomists share what they are seeing out in fields or are getting questions on. Some of the common observations include the drought stress resulting in crops shutting down early, tar spot becoming more prevalent in fields, sudden death...
While the story of the "haves" and "have nots" continues across the state, some areas in NW did finally get some much-needed rain early this week. And unfortunately, the Zearing area in Central Iowa also had some hail damage. Some of the observations or questions coming in from the field this...
You are invited to attend the upcoming field days that will be hosted at the outlying Iowa State University Research and Demonstration Farms this fall. These field days will feature the latest information on crop production and crop management practices. Below is a list of the upcoming field...
It’s the story of the haves and have nots when it comes to rainfall across the state. Unfortunately the areas that could really use the rain, seem to miss the rains. Consequently, some parts of the state are looking pretty tough with the drought conditions. Besides the drought conditions in...
Parts of the state are classified as being abnormally dry to being in an extreme drought based on the most recent U.S. Drought Monitor map. With the hot temperatures returning this week and little to no rainfall...
The past week brought again spotty rainfall across the state. With the dry conditions and warmer temperatures forecasted there are concerns about what this may mean for the crops. Spider mites, corn rootworms, grasshoppers, aphids, and weed escapes were other observations or concerns coming from...
Signs of stress could be seen in corn and soybean fields, especially in the drier areas of the state with the warmer temperatures last week. Most of the corn either has pollinated or is pollinating and soybeans are in the R2 to R3 growth stages. Corn rootworm beetles, Japanese beetles, drought...
With hot weather and few rain chances in the forecast, concern turns toward soil moisture reserves and the ever-important pollination timing in corn. ISU Extension field agronomists observed corn rootworm beetles, Japanese beetle feeding,...
While there was some much-needed rain across the state last week, the rain also brought some wind with it as well that resulted in lodged or leaning corn as well as some greensnap in fields. In addition to the wind damage, herbicide injury in soybeans, tar spot concerns, and Japanese beetles...
Herbicide injury in soybean, Japanese beetles, potato leafhoppers in alfalfa, tar spot being found in Marshall and Jones counties (and some additional counties since) at low levels, and some hail damage in NE Iowa were some of the issues observed by ISU Extension field agronomists this last week...
While most areas received some needed rain last week, some areas in Western Iowa continue to miss out on the rain or get minimal amounts of rain and it’s starting to show more in the crops. Getting out in the fields, some pests or issues observed by...
Isolated hail and wind damage, iron deficiency chlorosis, herbicide damage, and moisture stress (too much or too little depending upon the area) were some of the big issues that ISU Extension field agronomists noted in fields across the state. Read on to for more specifics about what’s happening...
Farmers and farm businesses are invitied to join us on July 7 at Southeast Research and Demonstration Farm near Crawfordsville for our Agronomy Workshop and Certified Crop Advisor Training in the morning and our Summer Field Day in the afternoon. These events are being hosted by the research...
While parts of western Iowa seem to miss the rain or get small amounts of rain, other parts of the state received over 3 inches of rain this past week and experienced flooding. Unfortunately, some areas, particularly southwest and south-central Iowa, received some significant hail damage as well...
Cutworms and armyworms, flooding, replant considerations, and weed management/herbicide application considerations were some of the more common questions ISU Extension Field Agronomists received over this last week. Read on for more specifies about what is happening and being seen across the...
Regional Update: May 23 – June 1, 2022
With planting wrapping up across the state, the attention is focusing to taking the first cutting of alfalfa, herbicide applications, and starting sidedressing nitrogen in corn. Read on to hear what ISU Extension Field Agronomist’...
Weather conditions were quite favorable this past week allowing Iowa farmers 5.4 days for fieldwork across Iowa allowing for significant planting progress across nearly all of Iowa. With that said, there are still isolated pockets where soils remain too wet to allow for fieldwork. Frost...
Farmers finally caught a break last week and were able to make a lot of planting progress across most of the state. Some areas that did not miss the rains last week had more limited progress made with getting the crop in the ground. The earlier planted crops and even some of the crops put in...
While not much planting progress was made last week (again), the warmer and drier weather this week should provide more favorable conditions for fieldwork and planting. Some of the hot topics over the last week across the state included concerns about cover crop termination, seeding forages yet...
It has been a slow start to the 2022 growing season with minimal fieldwork and planting done across the state. According to the USDA-NASS May 2 Crop Progress...
The cooler temperatures this spring have slowed down alfalfa growth, but alfalfa weevil could already be active based on growing degree day (GDD) accumulation since January 1. We recommend beginning...
