Western Integrated Pest Management Center

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. 

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.

In south-central Colorado’s high desert, Rockey Farms has followed a path toward increased sustainability. Beginning with integrated pest management, the multi-generational family farm has experimented and implemented one new farming practice after another, steadily increasing its sustainability, profitability, soil health and crop quality.

And it began with IPM.

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.”

The city and county of Boulder, Colorado illustrate IPM perfectly. They each have weeds to manage on public land, but because their goals, weeds, acreage and approaches differ, their management differs.

The U.S. Animal and Plant Health Inspection Service has proposed lifting the domestic quarantine designed to slow the spread of emerald ash borer, an action that could speed the destructive insect’s introduction into Western states that have so far kept it at bay.

As part of its urban planning, the city of Denver recently asked residents what they wanted most in a revitalized downtown and they chose trees. It’s a shame so many of them are about to die.

As herbicide-resistant weeds become more common across the country, researchers and growers are looking for other ways to control weeds. In Colorado, they’re looking at harvest weed-seed control, IPM-friendly methods designed to destroy or remove weed seeds during harvest.

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

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.

How do you get teachers interested in integrated pest management? Turn IPM into a science curriculum they can use in their classrooms.

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.

Hop growers in the Northwest - as well as a sweet cherry, apple and other fruit growers around the nation - now have a new mating disruption tool to combat the Prionus beetle and its root-boring larvae, thanks to research funded in part by the Western IPM Center.

When an invasive species is first detected in an area, the initial response is critical. Like with a cancer, the correct early detection and response can make a big difference in controlling the spread and severity of the outbreak.
