Western Integrated Pest Management Center

Call it puncturevine, goatheads, devil’s thorn or whatever creative collection of expletives you mutter after sitting, kneeling or stepping barefoot onto it, Tribulus terrestris is one unpleasant plant. But with funding from the Western Integrated Pest Management Center, a researcher in New Mexico is measuring the cold-hardiness of weevils from different climactic zones to see if biocontrol efforts in cool northern climes could be boosted by importing warm-weather weevils from southern deserts.

Most people driving through Arches National Park in southeast Utah look up, marveling at the unique rock formations that give the park its name. Kelli Quinn looks down. 

Quinn is a National Park Service team lead for the vegetation and ecological restoration program at Arches and three nearby national parks and monuments and it’s her job to keep the native, natural landscape as native and natural as possible.  She and her colleagues use integrated pest management techniques to do that.

Moab, Utah is known as one the nation’s premier outdoor destinations, drawing millions of visitors each year to bike on its famed slickrock trails, hike through its painted canyons or 4x4 across its rugged desert.

What Moab is not known for – and the community wants to keep it that way – is mosquitoes.

Pesticide Educational Resources Collaborative-Medical produces educational materials and resources on pesticides,  specifically targeting health care providers so they can recognize, treat and report pesticide-related illnesses.

For weed scientists and growers, Western Australia is a cautionary tale. Herbicides failed, resistant weeds spread unchecked and non-chemical control methods had to be developed on the fly to keep the grain industry in business. As herbicide-resistant weeds spread in the United States, researchers are trying to adapt some of the lessons learned in Australia here at home, including harvest weed-seed control, before the situation gets as dire. 

Start with a heaping helping of weeds in an orchard owned by an electrical engineer, then add in a weed scientist and a dash of Western IPM Center funding. What you get is electric weed control – a promising (dare we say shocking?) new way to control weeds in certain landscapes.

As students return to classrooms in the fall of 2020, coronavirus is very much on people’s minds. In the West, having an IPM program in place seems to be helping schools plan for reopening.

Kochia is a tumbling weed plaguing growers and ranchers from Central Canada to West Texas.

“It’s salt tolerant, heat tolerant, cold tolerant,” said Kent Davis, a crop consultant with Crop Quest in Colorado. “I want to kill the damn stuff, there’s no question about it, but you have to admire it at the same time.”

As pests go, wild pigs are huge – and hugely effective.

Native predators like kestrels and barn owls can play a valuable role in controlling pests not only on farms, but also in parks, golf courses and large yards and gardens. While they rarely eliminate a pest problem, they can reduce the need for pesticide use and other pest-control measures.

As an ecosystem-transformer species, medusahead is among the worst weeds. Not only does it compete for resources with more desirable species, but it changes ecosystem function to favor its own survival at the expense of the entire ecosystem.

Researchers, ranchers, and land managers know that livestock grazing can be a valuable and selective noxious-weed management tool, and this guide summarizes all the effective techniques.

Conventional wisdom says cows don’t go up steep slopes. They don’t climb hills and don’t travel very far from water. But some cows never got that memo, and researchers are looking into whether naturally hill-climbing cows can provide production and environmental benefits in the rugged West.

Both pests and pesticides in schools can pose a health risk to children, so promoting IPM practices in schools is doubly important. That's why the Western IPM Center has been helping Western researchers develop regional resources and promote school IPM.

Both pests and pesticides are potentially harmful for kids and adults in schools. Common schools pests like the German cockroach or mice can carry disease and cause allergic responses. And children can be more at risk for harm from sprayed pesticides because of their behavior – playing on the floor or in grassy fields, for instance – and because of their developing physiology.

An update to the Pest Management Strategic Plan for dry bulb storage onions shows progress against thrips and Iris yellow spot virus, but still challenges to overcome.
