California

Here are summaries of some of the IPM research, innovations and projects going on in California, or benefitting California agriculture, communities and natural areas. Projects listed here are not necessarily funded by the Western IPM Center.

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.



Safflower Makes an Areawide IPM Program Work

Safflower, a low-value oil seed crop, is the key to an incredibly successful soil health and areawide integrated pest management program in California — and a great illustration of how IPM works. 



Embracing Functional Agricultural Biodiversity to Tap into Nature's Services

Bringing natural diversity to a farm can help boost production and benefit the bottom line. The concept is called functional agricultural biodiversity, and a work group in Oregon is helping Pacific Northwest farmers and conservationists know what plants to incorporate, insects to encourage and habitat to install to maximize their natural benefits.

In Kings County, California, safflower is an important rotational crop that improves the soil health and makes farming more productive. It's also the key to an areawide IPM program that manages pests and reduces pesticide sprays.



VIDEO: Functional Agricultural Biodiversity

Farmers embracing functional agricultural biodiversity incorporate habitat for beneficial insects and wildlife on their farms - and benefit from the ecosystem service that habitat provides.

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: 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.



Tribal Work Group

The Western Region Tribal Work Group brought together representatives of several tribes and federal agencies to combat invasive species on tribal lands.



Toolkit for Assessing IPM Outcomes and Impacts

The Western IPM Center’s IPM Adoption and Impacts Assessment Work Group, a collection of natural and social scientists from across the country, created online resources showing IPM researchers how to conduct basic impact assessments.



South American Palm Weevil

The South American palm weevil is a serious palm pest in its native range in Mexico, Central and South America. It is highly likely that the insect has established permanent populations in southern San Diego County in an area that ranges, at least, from San Ysidro to Chula Vista. 



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.



Eco-Label Programs Promote IPM, but Aren't Perfect

There are dozens of eco labels and sustainable agriculture certification programs in the United States, all designed to differentiate products in the marketplace and assure consumers that this apple, potato or bottle of wine was produced in an environmentally responsible manner. 

And eco-label programs do have clear benefits and promote more sustainable pest-management and growing practices. They also provide certain benefits for growers. 

However, there are downsides for growers as well, and significant differences between the programs can make judging eco labels challenging for consumers. And with dozens of similar yet competing certification programs and standards, certification chaos is likely for the foreseeable future.

 


Croptime Project Expands Pest-Modeling Website to Include Vegetable-Development Models

Pest managers are familiar with the concept of using degree days to predict pest outbreaks. Insects, like many other organisms, develop according to the temperature around them and degree days are a way to measure accumulated temperature.

Plants – at least in part – also develop based on temperature, so a team in Oregon is adapting a degree-day modeling system built for pest management to make a tool for vegetable growers to better plan their planting and harvesting dates.



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.”



Identify Herbicide Damage to Crops and Ornamental Plants

Identifying nontarget crop and ornamental plant damage from herbicides has become much easier, with the launch of a new online photo repository by the University of California Statewide IPM Program.



Small Farms IPM Group Finds Invaders, Opportunities and Challenges

Bringing IPM information to small-scale farmers is a significant challenge, but one that has many potential benefits - including expanded opportunities to spot invasive pests and diseases.



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.
