UW plant pathologist describes bacterial leaf streak of corn

A new publication from the University of Wyoming Extension details bacterial leaf streak of corn.

The disease is not yet in Wyoming but is in nine states, including Nebraska, Colorado and South Dakota, said William Stump, assistant professor of plant sciences in the College of Agriculture and Natural Resources.

In “Disease alert: Bacterial leaf streak of corn,” the extension plant pathologist explains the disease symptoms and disease cycle and management.

The disease was first detected in Nebraska in 2014 and confirmed in 2016. The origin of the disease in the U.S. is not known, nor are the mechanisms by which it has extensive spread, Stump said.

The bulletin is available for free download by going to uwyo.edu/uwe and clicking on the Publications link. Type in B-1301 or the title in the search field and click on the link. The publication is available in PDF, HTML or ePub formats.

UW center near Lingle hosts sugarbeet micronutrient, moisture sensor workshop

Extension irrigation specialist Vivek Sharma. who is based at the Powell Research and Extension Center.

What micronutrients are needed and when by sugarbeets to get maximum yields and soil moisture sensor field demonstrations are topics of a mini-field day 10 a.m.-noon Wednesday, Sept. 6, at the James C. Hageman Sustainable Agriculture Research and Extension Center near Lingle.

University of Wyoming Extension irrigation specialist Vivek Sharma will discuss micronutrient applications to sugarbeets.

Research has shown micronutrients can help grow bigger roots, increase leaf area and cause earlier canopy closure with an increased sugar percentage and tonnage per acre, said Caleb Carter, UW Extension educator. The project is in collaboration with Agriscience Technologies.

For the soil moisture sensor project, Sharma has installed several different types and will discuss the differences in their operation, maintenance and data interpretation.

There is no cost for the workshop but RSVPs for lunch would be appreciated, said Carter. Call him at 307-532-2436 to RSVP or with any questions.

Powell R&E Center hosts micronutrients for sugarbeets mini-field day

Vivek Sharma

What micronutrients are needed and when by sugarbeets to get maximum yields with the least stress is the focus of a mini-field day at the Powell Research and Extension Center.

The free workshop is 10:30 a.m.-noon Monday, Sept. 11, at the center north of Powell, said Jeremiah Vardiman, University of Wyoming Extension educator. Lunch is provided.

Vivek Sharma’s micronutrient management in sugarbeet research will be highlighted during the field demonstration and discussion. Sharma is an assistant professor of agronomy and extension irrigation specialist with UW.

Vardiman said Sharma’s research seeks to improve seedling vigor and root growth, increase leaf surface area and potentially reduce nitrogen applications while driving late-season sugar percentages and tonnage with micronutrient management.

“This research is honing the knowledge to more uniform and better beet emergence, building stronger and bigger roots in spite of cold wet conditions and improve seedling vigor,”
said Vardiman.

Early-season foliar applications drive row closure by increasing leaf surface area and late-season foliar applications drive sugar content into the beet at the end of the season, he said.

For more information or to RSVP for lunch, contact Sharma at 307-754-2223.

Two-day workshop prepares producers, emergency responders for ag emergencies

Emergency response and planning for agricultural emergencies are part of a two-day training workshop in Casper for producers and government entities.

The “Wyoming Ag Responder Academy” is Friday-Saturday, Sept. 8-9, at the Central Wyoming Fairgrounds in Casper, said Scott Cotton, University of Wyoming Extension educator and a presenter during the course.

The sessions are sponsored by UW Extension, Colorado State University Extension and Montana State University Extension addressing specific needs of western states that have fewer resources, deal with greater distances and more community dependence on agriculture, said Cotton.

UW team studies how ranch economics affected by sage-grouse conservation efforts

John Tanaka, associate director of the Wyoming Agricultural Experiment Station

How greater sage-grouse conservation practices have affected ranch economics across six states is being studied by a University of Wyoming research team.

The group in the Department of Ecosystem Science and Management will draw input from local ranchers across Wyoming, Idaho, Montana, Nevada, Oregon and Washington, said John Tanaka, professor and associate director of the Wyoming Agricultural Experiment Station.

The team will develop cow-calf ranch enterprise budgets for use in models to estimate the economic impacts of different conservation practices on ranches, said Holly Kirkpatrick, one of the research assistants.

Partnerships between federal and state agencies and private landowners have reduced threats to greater sage-grouse in 90 percent of the species’ breeding habitat, said Tanaka. He said the practices have changed the way livestock are grazed on millions of acres of land across the western United States, especially on public lands.

“Ranchers manage extensive areas of those lands and are critical to help keep the bird from being listed as threatened or endangered in the future,” said Tanaka. “The project will assess how ranchers and the communities in which they operate have been affected.”
