University of Wyoming researchers will use kochia in a five-year study to help find a solution to weed-resistance to herbicides.

Department of Plant Sciences associate professor Andrew Kniss has received a National Institute of Food and Agriculture grant to analyze methods of weed control other than herbicide.

Experimental kochia populations will be seeded in fields without major infestations, and all sites will be sprinkler irrigated, said Kniss, in the College of Agriculture and Natural Resources. The populations will have herbicide-resistant and susceptible strains at a known ratio. The fields will be exposed to varioustreatments including crop rotation and tillage. Soil samples collected eachfall will be used to record management practice data relative to kochia.

The sites are at research stations near Powell, Scottsbluff, Neb., and Huntley, Mont.  The sites represent three different regions significantly affected by the study’s weed-of-choice.

In-depth presentations that highlight research projects at the University of Wyoming’s Laramie Research and Extension Center are part of the open house at its Greenhouse Complex Thursday, Aug. 29, in Laramie.

The new format is based upon suggestions from last year’s open house, said Doug Zalesky, LREC director.

“This gives us time for questions and gives the presenters more time to provide information withouttrying to hurry through their information,” he said.

The Greenhouse Complex is at the corner of North 30th and East Harney streets. Tours begin at 4 p.m. and dinner is at 5 p.m. Presentations are 6-7:30 p.m. and include weed control, native plants and revegetation, high tunnel production and wind and solar power options.

“I am excited to have extension energy coordinator Milt Geiger provide information on green energy options that can apply both to producers and to those with high tunnels or gardens,” said Zalesky. “ It is not possible to highlight all of the projects and activities that are ongoing at the greenhouse, so each year we try to highlight new ones.”

Afternoon sessions at Sheridan College for producers and for homeowners follow crop variety trial tours in the morning near Wyarno during the Sheridan Research and Extension Center (ShREC) Field Day Saturday, June 15.

Registration begins at 9 a.m. and tours start at 9:30 at the Wyarno site seven miles east of the Sheridan Information Center on 5th street, said Valtcho Jeliazkov, ShREC director.

Tours include reclamation projects, a reclamation project using coal-bed methane water, alfalfa variety and sainfoin trials, a homeowner turfgrass demonstration trial, trials with oilseeds for biodiesel production and organic gardens. Also toured will be high tunnel grape production and the apple orchard.

The venue then switches to the Sheridan College Science Center building for a tour of the Adams Ranch forage trial and vineyard, and also forage, oilseeds, specialty crops and sugar beet trials close to the science building.  Lunch will be provided to anyone who registered at Wyarno or who RSVPs in advance, said Jeliazkov. RSVPs are requested by Monday, June 10, by calling 307-737-2415 or by email at shrec@uwyo.edu.
