Here are summaries of some of the IPM research, innovations and projects going on in Colorado, or benefitting Colorado agriculture, communities and natural areas. Projects listed here are not necessarily funded by the Western IPM Center.
Detecting a Hidden Weed with Drones
Just like the early bird gets the worm, early detection is often what gets the weed. But hairy willow-herb can be difficult to find. After finding that mature plants were easily visible by drone, Jake Courkamp, a rangeland weed ecologist at Colorado State University, and collaborators are testing if drones can find earlier life stages of this weed.
Testing the Ecology of Fear in Colorado Chile Pepper Fields
Tiny aphids are causing outsized losses for Colorado growers by transmitting alfalfa mosaic virus to pepper plants. The insects aren’t in the crop long enough for insecticides to be effective, and because the aphids don’t stay in chile fields, neither would the beneficial insects that eat them. So Colorado State University graduate student Lara Amiri-Kazaz is researching something novel: fear.
Exploring a Fiery Method for Replacing Invasive Grasses
In California and throughout the West, land managers face huge challenges on huge acreage. Threats include invasive annual grasses, drier summers and changing fire regimes. To combat this combined threat, UC Davis researchers are testing a burn-and-replant method as a combined solution.
Work Group Aims to Make New Endangered Species Rules Workable
“If it’s so complex that it’s impossible, then no one wins.”
That was the key takeaway from a recent two-day workshop in Vancouver, Washington about implementing new U.S. Environmental Protection Agency pesticide-use rules to protect endangered and threatened species.
Group Educates Health Care Providers about Pesticide-Related Illnesses
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.
Evaluating Chaff Lining for Weed Control in Dryland Crops
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.
IPM Experience is Helping Schools Plan for Reopening Amid COVID Concerns
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.
Looking for Answers as Kochia Rolls Across the West
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.”
Dropping the Emerald Ash Borer Quarantine Could Impact the West
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.
Preparing for the Invasion: Emerald Ash Borer in Colorado
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.
Targeting Weed Seeds at Harvest
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.
Feral Swine Wreak Havoc
As pests go, wild pigs are huge – and hugely effective.
Bed Bug Website and Work Group Share Knowledge and Resources
Through a website or workshop, the members of the Western IPM Bed Bug Work Group can teach you everything you ever wanted to know about bed bugs – and then some.
Eco-Label Programs Promote IPM, but Aren’t Perfect
Eco-label programs have clear benefits and promote more sustainable pest-management and growing practices. They also provide certain benefits for growers but have downsides as well. Significant differences between the programs can make judging eco labels challenging for consumers, and with dozens of similar yet competing certification programs and standards, chaos is likely for the foreseeable future.
Decoding Chemical Communications to Control Insects
University of California, Riverside chemical ecologist Jocelyn Millar identifies the chemical signals insects use to communicate, then synthesizes versions of them to help monitor, trap or disrupt their activities. Lygus bug is just one of dozens of species Millar and his team are working on. The common thread is that they all communicate chemically, and decoding those chemical signals can create new ways to control those species where they are pests.

Hill-Climbing Cows May Bring Big Benefits to Western Rangeland and Ranchers
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.
School IPM Protects Kids from Pests and Pesticides
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.
Grazing Guidelines for Noxious Weed Control
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.
IPM Adoption is Widespread in the West
Many integrated pest management practices are so widely adopted in Western agriculture they have become conventional pest management. That is one of the key findings of a new report by the Western Integrated Pest Management Center titled Adoption and Impacts of Integrated Pest Management in Agriculture in the Western United States.
Colorado Battling Emerald Ash Borer with Coordination and Cooperation
In Boulder, Colorado, Assistant Forester Kendra Nash was marking a dead tree for removal, when her spray-painted “X” crossed a D-shaped exit hole characteristic of the insect. The September 2013 discovery was the first in Colorado of the invasive beetle that’s killed tens of millions of trees since first being detected in Michigan in 2002. Here’s what’s happened since.
IPM Curriculum for Elementary Students Creates InPESTigators
How do you get teachers interested in integrated pest management? Turn IPM into a science curriculum they can use in their classrooms.
Montana Develops Weed Seedling Guide for the Northern Great Plains
Rapid and accurate identification of weeds at the seedling stage can save producers and land managers time and money but most weed identification guides only provide information about the mature stage of the plants. Not this one.
New Guide Helps Land Managers Control Medusahead
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.
Boosting Invasive Species Cooperation Using Zebra Chip as a Model
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.
Center Funding Helps Develop a Better Way to Control Prionus Beetles
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.
Protecting Kids from Pests and Pesticides by Promoting IPM in Schools
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.
Progress against Onion Pests
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.
