Hundreds Of Scn-Resistant Soybean Varieties Available For 2014, Gregory L. Tylka 2014 Iowa State University

Hundreds Of Scn-Resistant Soybean Varieties Available For 2014, Gregory L. Tylka

Integrated Crop Management News

The soybean cyst nematode (SCN) is a serious yield-reducing pathogen of soybeans. It is present in many fields throughout the Midwest, wherever soybeans are grown.

To produce profitable soybean yields in fields infested with SCN, farmers should grow SCN-resistant soybean varieties. SCN-resistant soybeans can produce high yields while keeping SCN population densities from increasing.

Terminating Cover Crops, Robert G. Hartzler 2014 Iowa State University

Terminating Cover Crops, Robert G. Hartzler

Integrated Crop Management News

There is an increased interest in the use of cover crops due to the many agronomic and environmental benefits they offer. An important consideration when incorporating cover crops into the system is their termination. Failure to completely control cover crops at planting results in them acting as a weed and competing with the crop. Several factors influence the effectiveness of burndown treatments, including the cover crop species and growth stage, the herbicides and rates used, application parameters and environment.


Start Scouting For Alfalfa Weevil With Updated Economic Thresholds, Erin W. Hodgson 2014 Iowa State University

Start Scouting For Alfalfa Weevil With Updated Economic Thresholds, Erin W. Hodgson

Integrated Crop Management News

Even though it was an extremely cold winter, some alfalfa weevil adults are expected to survive. Adults will begin moving as soon as temperatures exceed 48°F and begin laying eggs in alfalfa. Alfalfa weevil eggs develop based on temperature, or accumulating degree days, and hatching can start around 200-300 degree days. Start scouting alfalfa fields south of Interstate 80 at 200 degree days and fields north of Interstate 80 at 250 degree days. Based on accumulated temperatures since January, weevils are active in southern Iowa now and scouting to monitor for larval activity should start in southwestern Iowa this ...


Predicted Mortality Of Bean Leaf Beetle Is Highest In 25 Years, Erin W. Hodgson, Adam J. Sisson 2014 Iowa State University

Predicted Mortality Of Bean Leaf Beetle Is Highest In 25 Years, Erin W. Hodgson, Adam J. Sisson

Integrated Crop Management News

Bean leaf beetle adults are susceptible to cold weather and most will die when the air temperature falls below -10°C. However, they have adapted to winter by protecting themselves under plant debris and loose soil. An overwintering survival model was developed by Lam and Pedigo from Iowa State University in 2000, and is helpful for predicting winter mortality based on accumulating subfreezing temperatures. Predicted mortality rates in Iowa were extremely high during the 2013-2014 winter and ranged from 89-99 percent (Fig. 1). Not surprisingly, central and northern Iowa experienced colder temperatures, and most of the bean leaf beetle adults ...


Myths And Facts About Residue Breakdown, Mahdi Al-Kaisi 2014 Iowa State University

Myths And Facts About Residue Breakdown, Mahdi Al-Kaisi

Integrated Crop Management News

Crop residue serves an important role in physically protecting soil by preventing soil erosion during rain events or high winds. Also, crop residue plays a significant role in enhancing the soil biological community by providing sources of organic carbon and nitrogen for its energy or food needs. To understand how residue decomposes or breaks down, we need to understand the processes and mechanisms that include both biological and chemical activities influenced by environmental and soil conditions, namely air and soil temperatures, soil moisture availability, soil pH, oxygen, and type of microbial community. The composition of crop residue includes lignin, cellulose ...

Compressed Spring Workload In 2014? What Are Nitrogen Application Options?, John E. Sawyer 2014 Iowa State University

Compressed Spring Workload In 2014? What Are Nitrogen Application Options?, John E. Sawyer

Integrated Crop Management News

It was a long winter, with conditions this spring suitable for field work perhaps being later than normal. Also, some areas of Iowa did not have the typical amount of fall anhydrous ammonia applied. Questions are already coming about options for nitrogen (N) fertilization this spring, and the usual question should time be taken to get N applied or plant corn and apply N later.


A Functional Framework For Improved Management Of Western North American Aspen (Populus Tremuloides Michx.), Paul C. Rogers, Simon M. Landhausser, Bradley D. Pinno, Ronald J. Ryel 2014 Utah State University

A Functional Framework For Improved Management Of Western North American Aspen (Populus Tremuloides Michx.), Paul C. Rogers, Simon M. Landhausser, Bradley D. Pinno, Ronald J. Ryel

Wildland Resources Faculty Publications

Quaking or trembling aspen (Populus tremuloides Michx.) forests occur in highly diverse setting across North America. However, management of distinct communities has long relied on a single aspen to-conifer successional model. We examine a variety of aspen dominated stand types in the western portion of its range as ecological systems; avoiding an exclusive focus on seral dynamics or single species management. We build a case for a large-scale functional aspen typology based on existing literature. Aspen functional types are defined as aspen communities that differ markedly in their physical and biological processes. The framework presented here describes two “functional types ...

Spring Tillage Pitfalls, Mahdi Al-Kaisi 2014 Iowa State University

Spring Tillage Pitfalls, Mahdi Al-Kaisi

Integrated Crop Management News

Generally, springtime is not an ideal time for conducting tillage because of potential negative soil and agronomic outcomes associated with tillage in wet conditions. These soil and agronomic problems are linked together in affecting yield. Here are some of the reasons to avoid spring tillage.

An Index Of California Regulations Affecting Rice Growers, Maddie Dunlap 2014 California Polytechnic State University

An Index Of California Regulations Affecting Rice Growers, Maddie Dunlap

Agricultural Education and Communication

The purposed of this project was to identify and compile California regulations that affect rice growers. The final product was an index designed for rice growers and their representatives to be used lobbying efforts with regulators and elected officials. The index serves to illustrate the intensive regulations that rice growers face in California. Areas of focus include water quality, air quality, labor and pesticides indirectly.
