Integrated Pest Management

Nevada Department of Agriculture’s records show the use of traditional pesticides continues to increase in the state. Nevada’s Integrated Pest Management (IPM) program helps agricultural producers, land managers; pest control operators, homeowners and other pest managers learn about and use alternative pest management strategies in a variety of environments and settings.


The Western Area’s Horticultural Needs Assessment targeted IPM as a top educational programming need. Nevada Department of Agriculture’s records show the use of traditional pesticides continues to increase in the state. Just one threat is excessive Mormon cricket invasions (a $6-million allocation for their management). Increased urban sprawl into native lands and heavy pest pressures in drought-stressed agricultural crops such as timothy hay all require improved pest management systems that are less dependent upon traditional pesticides. Also, production and marketing of organic products increases the alternatives to the traditional use of pesticides.

Meanwhile, weeds are one of the most serious threats to Nevada rangelands and lawns. Noxious weeds have already invaded thousands of acres of Nevada’s ands and waterways. They threaten water quality, wildlife habitat, recreational activities and the economic stability of ranchers, farmers and other land managers.

What Has Been Done:

Nevada’s Integrated Pest Management (IPM) program helps agricultural producers, land managers; pest control operators, homeowners and other pest managers learn about and use alternative pest management strategies in a variety of environments and settings. Nevada efforts target the national IPM program’s four objectives: 1) to safeguard human health and the environment, 2) to increase the range of benefits achieved by those who use IPM methods, 3) to increase the supply and dissemination of IPM knowledge, and 4) to enhance collaborations among stakeholders.

In Nevada, the IPM program addresses rural and urban issues on several scales and with a broad range of clientele. Programming strategies and activities are addressing identified needs, which include, but are not limited to, 1) integrated invasive weed management in all environments across Nevada, including the development and strengthening of Cooperative Weed Management Areas (CWMAs), 2) educating and training pest control operators to use IPM in their pest management work, particularly in urban settings, 3) educating homeowners to use adapted, environmentally friendly landscaping principles and practices and to use IPM to reduce the use of pesticides and improve their immediate environment, 4) increased integrated pest management for hay crops and 5) initial and continued training of Master Gardeners, Weed Warriors and other volunteers in science-based IPM strategies and, when necessary, the use of biorational and least toxic pesticides.

To Safeguard Human Health and the Environment: Cooperative Extension teaches pest ID, pest mapping, pest monitoring, and cooperative management among public agencies and private entities using IPM techniques, watershed IPM management, and reduced pesticide reliance. The following techniques are used: inspection and quarantine of invasive species in products shipped into Nevada; mowing, fire, cultivation; modifying cultural practices; predators, biologicals, grazing; and soft and traditional chemicals.

To Increase the range of benefits achieved through IPM Technologies or Strategies: Cooperative Extension is working with agencies and private land managers in mapping invasive weeds as part of their commitment to and participation in Cooperative Weed Management Areas (CWMAs). Cooperative Extension trains volunteers, who are participating in Weed Warrior training, helping neighborhoods and local organizations understand the impacts of invasive species, cooperating in weed pulls (Reno, Spring Creek, Lake Tahoe and Las Vegas), promoting integrated weed management (IWM) and providing public awareness of the invasive species issues.

To increase the dissemination of IPM Knowledge: A broad public education campaign aimed at the residents of the Truckee Meadows was conducted with a newspaper insert on weeds; a one-hour High Desert Forum radio feature on KUNR public radio; design and content for a weed group website ( was completed; messages from the hotline transcribed by Weed Warrior volunteers; three versions of bus tail panels displayed on 10 Regional Transportation Commission busses for four months and two, 2- hour volunteer weed "Dig-It" events.

Nevada Weed Management Association held a successful conference with support from University of Nevada Cooperative Extension, the IPM program, Nevada Department of Agriculture, other state and federal agencies and private individuals. Presentations, panel discussions and private strategizing included plant identification, the economics of invasive weeds and their management, cooperatively managing watersheds and basins for invasive weeds, Integrated Weed Management (IWM), and discussion of issues relating to management of cooperative weed management areas.

Hundreds of Weed Warriors, Woad Warriors, and other volunteers have been trained by UNCE personnel in how to spot, control and eradicate noxious weeds.


There are more than 30 coordinated weed associations and other groups in Nevada, according to the Nevada Department of Agriculture’s weed coordinator. These are formed among private entities, state agencies (conservation districts, parks, etc.) and federal agencies (BLM, FS, FWS, PS, etc.) usually with memoranda of understanding and work agreements.

UNCE faculty plays an active role in many of these groups, serving as catalysts, educators and grant consultants. The goal is to achieve long-term sustainability of the weed control efforts.

The number of active weed control districts has gone from three to six with three additional groups now forming with the help of Cooperative Extension. Within the past three years, the Tri-county Weed Management District was formed, mapped and successfully continues to treat and reduce the presence of noxious and invasive weeds in Lincoln, Nye and White Pine counties and on private and public lands.

Examples of volunteer group impacts include:

The Tahoe Weed Group mapped and treated a total of 282.9 acres in the Tahoe Basin, making significant progress in controlling invasive weed species and measuring a 20 percent decrease in total weed infestations from 2004 to 2005.

The Truckee Meadows Weed Group hired four seasonal staff to complete 12 weeks of weed mapping and control in 2005. Seasonal staff surveyed 12,454 acres and mapped 3,342 weed sites. Weed controls were implemented on 5,196 acres.

The Truckee Meadows education campaign was successful. The website was accessed 863 times by late-December 2005 and 27 Web-based weed reports were made by residents, in addition to 14 calls to the hotline. Transit advertising data estimates 6,032,400 gross impressions.

Master Gardeners continued to receive IPM training and disseminate IPM information to the public. In 2005, Nevada’s 600 Master Gardeners handled nearly 21,000 telephone calls, answered emails and gave presentations to thousands more Nevadans.

A research trial was conducted to determine the effectiveness of Christmas tree mulch from the annual recycling program as a control method for tall Whitetop. In spring 2005, plots were established to study the use of varying depths of Christmas tree mulch in controlling the tall Whitetop. Results from the mulch study were variable, but average canopy cover decreased with increasing mulch depth, and average number of stems also decreased with increasing mulch depth.

Cooperative Extension continues to work with the Nevada Hay Growers Association continues to provide a collective voice and leadership in hay growing issues, including IPM used in producing high quality grass hay for export.

Integrated Pest Management

Nevada Department of Agriculture’s records show the use of traditional pesticides continues to increase in the state. Nevada’s Integrated Pest Management (IPM) program helps agricultural producers, land managers; pest control operators, homeowners and other pest managers learn about and use alternative pest management strategies in a variety of environments and settings.

Integrated Pest Management (IPM) and IR-4 program

This program is to test potential pesticides necessary for producing forages in Nevada and submit requests for federal testing and registration from the IR-4 program, which is a federal cooperative program established in 1963 to help the producers of minor crops obtain clearances for pest control materials on those crops. The purpose of IR-4 is to work with farmers, agriculture scientists and Cooperative Extension personnel to carry out research and petition the Environmental Protection Agency (EPA) in order to obtain tolerances for specific pesticide uses needed by minor-crop producers.

Noxious Weed Control and Awareness Education

Noxious and invasive weeds are widespread throughout Nevada. They threaten agricultural and rangeland productivity. Rural counties are susceptible to significant adverse economic damage. University of Nevada Cooperative Extension education programs help individuals and weed control organization reduce the abundance of noxious weeds.

Project MAGIC

Project MAGIC is an innovative, collaborative program designed to help juvenile offenders leave the criminal justice system and become productive members of society. While participating in the program, young people ages 12 to 18 learn: positive communication skills, team building, problem solving and decision making, self-responsibility, conflict resolution, aspiration building and goal setting. Youth also select and conduct a service project designed to benefit their community. Parent sessions include the same life skills.

Risk Management

University of Nevada Cooperative Extension (UNCE) develops and delivers a comprehensive risk management education program to livestock and forage producers in Nevada.

Small business development in rural Nevada

While small business development courses have been offered in Nevada’s urban and metropolitan areas (Washoe and Clark counties) for some time, the need for economic development in rural counties is even more critical. University of Nevada Cooperative Extension offered business planning classes to existing and potential small-scale entrepreneurs through a series of interactive video and face-to-face classes.

Sustainable Agricultural Practices

University of Nevada Cooperative Extension conducts several sustainable agriculture programs including researching alternative crops, introducing sustainable biodiversity/multiple use of rangelands, and increasing the number of pest control materials labeled in and increasing the knowledge and implementation rate of IPM practices in Nevada.

Tef Crop Production

The purpose of this program is to introduce Nevada farmers to and help train them in the cultivation of tef, a small-seeded grain and forage crop that requires less water than alfalfa and can be more profitable. There is a strong market for tef seed, which is made into flour to make an Ethiopian flat bread known as injera, as well as for tef hay as a high-quality horse hay.
