Here are summaries of some of the IPM research, innovations and projects going on in Arizona, or benefitting Arizona agriculture, communities and natural areas. Projects listed here are not necessarily funded by the Western IPM Center.
Research Aims to Build an Integrated Management Plan for Organic Cotton
Comparing the pest-management power of conventionally grown cotton and organically grown cotton is like pitting the New York Yankees against local Little Leaguers. Yet with 20,000 acres of organically certified land in Arizona growing vegetable and field crops, organic cotton could be an important, and profitable, rotation crop.
Building Urban Agriculture in Arizona
When supply chains collapsed and grocery shelves sat empty in the first years of the COVID pandemic, many people got interested in growing their own food. Most of those only had access to small plots, not dozens or hundreds of acres of land. So in 2022, the Center for Urban Smart Agriculture was launched at the University of Arizona to serve urban farmers throughout the state and build that sector of Arizona’s agricultural economy.
Plant Risk Evaluator Tool Helps Identify Potentially Problematic Plants
The easiest pest to manage is the one that’s not there. That’s why prevention and avoidance are first two principles of integrated pest management’s “PAMS Approach,” with monitoring and suppression following behind. It’s also the rationale behind the Plant Risk Evaluator Tool, an online database to evaluate the potential for ornamental and horticultural plants to become invasive weeds in different areas and environments.
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.
Electric Weed Control Shows Promise
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.
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.”
Preparing for Zika in Arizona
During a 2016 outbreak of the Zika virus in Florida, it took repeated aerial pesticide sprays to kill the mosquitoes spreading the disease. Arizona has the kind of mosquito that can transmit Zika, but doesn’t allow the kind of aerial spraying Florida needed to stop the disease’s spread. And that raises a serious public-health question: If an outbreak of Zika occurred, could Arizona stop it?
The Impact of Firebreaks in Southern California Sage Lands
During wildfires, crew use bulldozers to cut firebreaks to remove vegetation and prevent the fire from spreading. It’s effective firefighting, but those bulldozer lines can have lasting impacts on the recovery of vegetation afterward. New research is measuring those impacts and developing mitigations.
Feral Swine Wreak Havoc
As pests go, wild pigs are huge – and hugely effective.
VIDEO: Using IPM to Protect a Long-Vanished Community
In the Arizona desert, the National Park Service and the University of Arizona teamed up to develop an integrated pest management program to protect sensitive archaeological sites from digging pests. IPM is being used to protect a community that vanished 1,000 years ago.
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.
School District Creates a Healthier Environment by Adopting IPM
Every day, nearly 7,000 students come to the Maricopa Unified School District’s six elementary schools, two middle schools and one high school outside Phoenix, Arizona. They’re joined on the campuses by more than 800 teachers and other employees. And every one of those people comes to schools that are healthier to learn in and teach in because the district embraced integrated pest management.
Protecting a Long-Vanished Community with IPM
The practices and principles of integrated pest management are used across the country to protect communities from pests. And in the Arizona desert, those same principles are being used to protect a community that disappeared 600 years ago.
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.
Tribal Bed Bug Workshop Dispels Myths
There is a lot of fear about bed bugs, and a stigma surrounding them that can keep some people from seeking help with a bed bug infestation. But bed bugs have been hanging around humans for a long time and aren’t going anywhere anytime soon.
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.
VIDEO: Gold Spotted Oak Borer, or GSOB, in Southern California
The gold spotted oak borer is a tiny beetle causing huge damage in Southern California. It infests the region’s towering oak species – coast live oak and canyon live oak – and can kill a centuries-old tree in just a year or two. This video follows the beetle from San Diego to Los Angeles counties to see what damage it’s doing and what many fear may come next.
VIDEO: Gold Spotted Oak Borer, or GSOB, in Irvine Regional Park
Weir Canyon in the Irvine Regional Park is the only known infestation of gold spotted oak borer in Orange County – and land managers are working hard to protect the park and keep the destructive beetle from spreading.
VIDEO: Where to Get Good Gardening Advice
In this video, Ariel Agenbroad from University of Idaho offers great tips for home gardeners about where to get good pest-management advice.
VIDEO: Urban Farm Pest Pressures and Solutions
Learn about the pest pressures faced by urban farmers — and how integrated pest management provides economical solutions — with Ariel Agenbroad, Local Food & Farms Advisor with University of Idaho Extension.
Gold Spotted Oak Borer Threatens Oak Woodlands and Ecosystems across Southern California
From San Diego County to Los Angeles County, oak trees are dying rapidly, killed by a tiny beetle called the gold spotted oak borer. In areas where the invasive pest has become established, it’s killing 80 to 90 percent of the mature oaks – a dieback that’s fundamentally changing the landscape and the ecosystem the oaks support.
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.
Can an Economic Model Show Growers the Importance of Reducing the Weed Seed Bank?
How important is it to keep weed seeds out of vegetable fields? Mexico State University’s Brian Schutte recently looked at that very question. Funded by the Western IPM Center, Schutte studied one particular weed, tall morning glory, in Southwest chile pepper fields, and developed an economic model growers can use to see for themselves how managing the weed seed bank can help their operations.
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.
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.
Using IPM to Battle Bed Bugs in Public Housing
Public housing presents unique pest-management challenges, including rapid turnover of residents, language and cultural barriers and even second-hand clothing and furniture. And those pest problems – especially when bedbugs are involved – can lead residents to resort to some pretty drastic and harmful pest control strategies.
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.
Spray Reductions in Cotton
For the past 15 years, researchers have been tracking pesticide use on cotton fields in the Southwest, and the reductions they’ve documented have been nothing short of remarkable.
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.
