An updated version of the popular Corn Field Guide is now available for purchase online. It includes over 200 photos and illustrations and environmental criteria to help identify diseases.
SCN-resistant soybean varieties produce profitable yields in fields infested with the nematode. There re hundreds of SCN-resistant soybean varieties from which farmers can choose. Iowa State has just released the updated list of resistant varieties in maturity groups 0, 1, 2, and 3.
This year's Integrated Crop Management Conference will feature presentations on traditional topics as well as ones of current interest, including past resistance to herbicides, fungicides and insecticides and sustainable biofuel production using perennial plants.
Meetings scheduled for December will give agriculture input providers up-to-date information on Pythium seedling disease, Palmer amaranth management, cover crops, soybean aphids, changes to nutrient management recommendations and more.
Fall is a perfect time to sample fields for the presence of the soybean cyst nematode (SCN). Knowing if SCN is present and at what population densities will increase the chances of profitable soybean production in 2014.
Now is a great time to spot Palmer amaranth infestations. The weed right now is much less mature than waterhemp, making it easier to see the differences.
Tobacco streak virus is being confirmed in Iowa fields. Learn how to identify the symptoms and where to send your plants for diagnosis.
Tillage reducing soil cover can compromise soil quality. Corn residue left on the field after harvest is a critical source of soil organic matter, provides protection against wind and water erosion, and improves soil water storage and quality.
Iowa State researchers are investigating green stem syndrom (GSS) in soybean and are looking for fields with any amount of GSS in them.
Crop conditions across the U.S. Corn Belt varied dramatically in 2013. Iowa was no exception and this year sits in a rare position in terms of yield potential: lower than several other Corn Belt states.
This harvest season will feature large variability in both corn and soybeans. Expect more problems in storage and a greater need to inspect and manage stored grain.
Recent field research indicates the need for some changes in nutrient management recommendations to improve the profitability and sustainability of crop production.
Producers in southwest and western Iowa are reporting an unusual disease in their fields. Read more about the symptoms and signs of Physoderma.
A recent Iowa State University survey assessed current corn rootworm management practices and the degree to which farmers perceived resistance in 2012. Read the results and contact the Iowa State University Department of Entomology if you suspect resistance.
Elwynn Taylor gives a video update on this year's difficult growing season and how an an early frost might impact production.
At casual glance, waterhemp can be easily mistaken for Palmer amaranth. While there is much overlap in there general appearance, there are distincitions you can make.
Crop producers with questions related to the late spring, dry summer and slow crop development should attend one of three upcoming meetings planned in north central Iowa.
Registration is now open for the Advanced RUSLE2 workshop, which will explore practice-based changes that can be implemented to reduce erosion.
Several soybean diseases are starting to make an appearance in local fields, including sudded death syndrome. Iowa State researchers want to study SDS-infected plants; find out how you can help.
An Aug. 30 field day at the Iowa State University research farm in Boone will focus on cover crops and corn production. The field day is free, and the public is invited to attend.
The simpliest and most cost-efficient manner of manaing Palmer amaranth, or any new weed species, is early detection and eradication.
The timing of the first 28⁰ F frost this fall will affect corn yield potential. A later than normal frost encourages longer seed-fill period and higher yields, while an early frost is not ideal.
Honeybee populations are declining across the United States. Here are some simple things you can do to help conserve bees.
Improve your knowledge of corn and soybean diseases by attending Iowa State University's annual late season disease workshop,
Have aphids in your fields? Here are a few scouting reminders and treatment thresholds for aphids in field crops.
Iowa State University agronomists are intrested in confirming the presence of Palmer amaranth infestations in Iowa.
The Neely-Kinyon Farm Field Day is scheduled for Tuesday, Aug. 20 in Greenfield. The focus will be on sustainable and organic ag topics.
Adult corn rootworm is active this year, so it is recommended that growers keep an eye on their fields in order to protect yield.
Drainage systems that are properly designed and operating are essential to achieving excellent agricultural production capability. Producers and others interested in this topic can learn more at the Iowa Drainage School August 20-22.
Cool, wet weather this spring reduced corn plant heights and increased variability of plant heights across fields. Shorter plants are not necessarily lower yielding. Whether corn is knee-high or elephant-eye high by the 4th of July is less important than whether the crop intercepts near maximum light at silking and the timing of the first major fall frost.
