USDA Announces Measures to Help Farmers Diversify Weed Control Efforts
WASHINGTON, Oct. 15, 2014 — Agriculture Secretary Tom Vilsack today announced several steps that the U.S. Department of Agriculture (USDA) is taking to address the increase of herbicide resistant weeds in U.S. agricultural systems.
"Weed control in major crops is almost entirely accomplished with herbicides today," said Vilsack. "USDA, working in collaboration with the Environmental Protection Agency, must continue to identify ways to encourage producers to adopt diverse tactics for weed management in addition to herbicide control. The actions we are taking today are part of this effort."
Today USDA is announcing several of the steps it is taking to help farmers manage their herbicide resistant weed problems in a more holistic and sustainable way:
- USDA's Natural Resource Conservation Service (NRCS) will offer financial assistance under its Environmental Quality Incentives Program (EQIP) for herbicide resistant weed control practices that utilize Integrated Pest Management plans and practices.
- Later this year NRCS will be soliciting proposals under the Conservation Innovation Grants (CIG) Program for innovative conservation systems that address herbicide resistant weeds.
- USDA's Animal and Plant Health Inspection Service (APHIS) will actively promote use of best management practices (BMPs) in design protocols for regulated authorized releases of genetically engineered (GE) crops and will include recommendations for BMPs with the authorization of field trials of HR crops.
- USDA is partnering with the Weed Science Society of America (WSSA) and is providing funds to develop education and outreach materials for various stakeholders on managing herbicide–resistant weeds. The Secretary has directed Dr. Sheryl Kunickis, Director of the USDA Office of Pest Management Policy, as the point person leading this effort with the USDA.
The issue of herbicide resistant weeds has become one of increasing importance for agriculture. When herbicides are repeatedly used to control weeds, the weeds that survive herbicide treatment can multiply and spread.
With EPA's announcement today on the registration of new uses for herbicide mixtures containing the herbicides 2,4-D and glyphosate (in the Enlist® formulation) in conjunction with new genetically engineered crop varieties, farmers are being offered one more new tool to better manage emerging populations of herbicide-resistant weeds in corn and soybeans crops. In its decision for 2,4-D use on genetically modified corn and soybean, EPA has outlined new requirements for registrants as part of a product stewardship program.
The USDA Office of Pest Management Policy worked with EPA to address the issue of herbicide resistance through appropriate label language that will require registrants to develop a stewardship program for the herbicide, develop training and education on proper use of the product that includes diversifying weed management, investigate and report nonperformance, and develop and implement a remediation plan for suspected herbicide resistant weeds.
EPA intends to require the same stewardship plans for all new applications for product registration on genetically modified crops with the goal being to encourage effective resistance management while maintaining needed flexibility for growers.
USDA recognizes that the problem of herbicide resistant weed control will not be solved solely through the application of new herbicides. USDA has worked with the Weed Science Society of America for a number of years on identifying best management practices for farmers and on addressing impediments to adoption of those practices.
USDA will continue to work to ensure that growers have the diverse tools they need to address the management of herbicide resistant weeds.
UC IPM Pest Management Guidelines for Olive" (UC ANR Publication #3452). You can download the whole document as a pdf here, or use it online at the above link.
Like the most of the other Pest Management Guidelines (PMGs), there are sections on management of a broad range of pests in olive including insects, mites, nematodes, vertebrate pests, and weeds. Since this is the UC Weed Science blog, here's the link directly to the Integrated Weed Management section authored by:
- B. Hanson, Weed Science, UC Davis. This revision was built on the past contributions of C. Elmore, Weed Science, UC Davis (emeritus), D.W. Cudney, Weed Science UC Riverside (emeritus), D.R. Donaldson, UCCE Napa Co., and W.T. Lanini, Weed Science, UC Davis (emeritus).
I think these PMGs are among the most useful sources of pest management information published by the UC Statewide Integrated Pest Management Program. These agricultural and home garden pest management guides are updated every year or so with extensive revisions every few years. The authors usually include University of California faculty, specialists, and farm advisors and the guides are produced and edited by UC Statewide IPM Program, University of California, Davis.
Visit the UC IPM homepage for more pest management information. This web resource gets nearly 50,000 pageviews per day by folks from around the world!
UCCE Position Announcement
If you've ever wished you could be a weed scientist with the University of California Cooperative Extension system (and really, who among us hasn't wished that?), this just may be your lucky day!
See the following job description and link for the position of Area Weed Ecology and Cropping Systems Advisor.
Area Weed Ecology and Cropping Systems Advisor
County Locations: Lassen County, Modoc County, Plumas County, Sierra County
Date Posted: October 7, 2014
Closing Date: December 5, 2014
The University of California, Division of Agriculture and Natural Resources, a statewide program with local development and delivery, is seeking a Cooperative Extension advisor to conduct a multi-county-based extension, education and applied research program. The programmatic focus of this position is weed ecology and cropping systems, providing leadership in research and extension for invasive weed management and forage crop production in the Intermountain sub-region.
The CE advisor will facilitate interactions and information exchange among campus-based academics, CE advisors and community stakeholders. The programmatic focus is expected to be directed on developing effective management strategies for invasive weeds that impact forage crop production systems and natural ecosystems and associated ecosystem services. The primary effort of the cropping systems program will be irrigated forage production, particularly high quality grass hay and irrigated pastures. The CE advisor will also have responsibility for the other crops grown in the area (e.g. alfalfa and cereal grains), coordinating and collaborating with neighboring CE advisors.
Below is a recent press release from the Weed Science Society of America (WSSA) announcing a new fact sheet addressing misconceptions about the so-called "superweeds".
I alluded to this few weeks ago in my post "Can herbicide resistance move from crops to weeds?" when I discussed the potential for gene flow from crops to weeds and how that might or might not affect the development of herbicide-resistant weeds. That earlier post was basically the working draft of background information provided to the WSSA committee that developed this new fact sheet.
[As an aside, at one point in time, I lived and breathed gene flow research. My PhD dissertation at the University of Idaho was on pollen-mediated geneflow among wheat cultivars and from herbicide-resistant weed to a related weed species called jointed goatgrass. It was fun to revisit some of those issues for this project]
The test of the WSSA press release is below and here is the direct link to the fact sheet "Dispelling Common Misconceptions about Superweeds"
Weed Scientists Uproot Common “Superweed” Myths
LAWRENCE, KANSAS – OCTOBER 8, 2014 – Today the Weed Science Society of America (WSSA) issued a new fact sheet to uproot common misconceptions about “superweeds”– a catchall term used by many to describe weeds resistant to herbicides. The paper explores the truth behind two widespread fallacies.
- Fallacy 1: Superweeds are a product of rampant gene transfer from genetically modified field crops. The truth:
WSSA scientists say gene transfer from some crops to certain weed species can happen, but it has not been a factor in the development of herbicide resistance across large acreages. The true culprit, they say, is overreliance on a single class of herbicides, resulting in selection for weeds that can survive the products in that class.
“Resistance to pesticides is not new or unique to weeds,” says Brad Hanson, Ph.D., a member of WSSA and Cooperative Extension weed specialist at the University of California at Davis. “Overuse of any compound class, whether antibiotic, antimicrobial, insecticide, fungicide or herbicide, has the potential to lead to reduced effectiveness. Although weeds resistant to herbicides were first reported more than a half century ago, integrated weed management strategies that included more tillage, more hand weeding and multiple herbicides kept them in check to a large degree. Today, however, it has become common in some cropping systems for farmers to repeatedly use a single class of herbicides to the exclusion of other weed control methods, and this has led to the growing problem with herbicide-resistant weeds.”
- Fallacy 2: Superweeds have supercharged abilities to muscle out competing plants in new and more aggressive ways. The truth:
Many believe today's herbicide-resistant superweeds exhibit properties unlike anything we've ever seen before. But WSSA scientists say bully-like weed behavior isn't new. In the absence of herbicides, resistant weeds are no more competitive or ecologically damaging than their non-resistant relatives.
All weeds – herbicide resistant or not – can outcompete other more desirable plants for water, nutrients, sunlight and space. They grow by leaps and bounds and can be prolific seed producers. A single Palmer amaranth plant, for example, can produce hundreds of thousands of seeds.
Scientists say the key to keeping weeds from causing dramatic changes in crop production is to adopt effective management strategies.
According to Andrew Kniss, Ph.D., WSSA board member and University of Wyoming faculty member, "Nearly any weed species can be economically devastating if left uncontrolled. It is important to incorporate a variety of weed management practices and not rely exclusively on herbicides for weed control. Monitoring weed populations is also important. Early recognition of resistant populations and rapid intervention can help reduce the impact these weeds have.”
The full WSSA paper on superweeds is posted online at http://wssa.net/weed/wssa-fact-sheets. The same website contains a variety of best management practices recommended by WSSA to combat herbicide resistance – from proactive steps to reduce the number of weed seeds in the soil to the use of well-established cultural practices to suppress weeds through crop competition.
