Epidemic in Turf Management: Herbicide Resistance in Annual Bluegrass

by Patricia McDaniels, University of Tennessee
Annual bluegrass is one of the most common weeds of turfgrass on golf courses, sports fields and sod farms, not to mention residential and commercial lawns. Unfortunately this nemesis of pristine landscapes has also developed resistance to many common herbicides. Researchers with the University of Tennessee Institute of Agriculture are participating in a national effort to address what many landscape managers call an epidemic of herbicide resistance in annual bluegrass plaguing managed turf systems.
As part of a $3.2 million, 15-state USDA Specialty Crop Research Initiative grant, UTIA turfgrass researcher Jim Brosnan will lead a team of Tennessee weed scientists in sampling annual bluegrass populations across the state. The team will travel the state’s three grand divisions to take samples from golf courses, sports fields, both residential and commercial lawns, as well as sod production farms. The sampled specimens will then be propagated in a controlled laboratory setting and tested for resistance to commonly used herbicides. The goal is to quantify the scope of herbicide resistance in annual bluegrass populations across Tennessee. Additionally, Brosnan’s team will also be developing new diagnostic assays to detect herbicide resistance in annual bluegrass, researching annual bluegrass seed persistence in soil, as well as the effects of turfgrass cultural practices on annual bluegrass infestation.

Webinar Recording is Online: Developing a Pest Exclusion Program for Cockroaches and Rodents

You can view the recorded webinar Developing a Pest Exclusion Program for Cockroaches and Rodents with Dr. Matt Frye here: http://stoppests.org/go/exclusion

Housing staff can now view this on-line training to learn about a vital part of any IPM program: exclusion. Keeping pests out of buildings is a priority in effectively addressing any pest infestation, but rodents and cockroaches in particular. To date there are no training guides on how to implement exclusion for pest management, which may prevent pest control companies from creating exclusion protocols. However, housing staff, especially maintenance and facilities staff and pest management professionals are uniquely qualified to identify entry points and harborage for cockroaches and rodents. This webinar emphasizes the steps in developing an exclusion program from the basics of identifying entry points to recommendations for sealing openings of different sizes and for different pests.

APHIS Adds Pale Cyst Nematode (Globodera pallida) Infested Field in Idaho

Effective October 10, 2018, the Animal and Plant Health Inspection Service (APHIS) added an 87-acre field to the pale cyst nematode (PCN) infested area in Bingham County, Idaho. APHIS took this action based on the confirmations of PCN cysts in soil samples from a potato production field in Bingham County received on September 25, 2018. This action brings the number of PCN-infested fields to 28 and the infested area to 3,130 acres.

Due to sharing of unwashed farm equipment and close proximity to this infested field, APHIS also placed an additional 93-acre field in Bingham County under regulation. In addition, APHIS made a geographic information system-based adjustment to the boundary of an associated field to improve accuracy of the regulated area map, which resulted in removing two acres under regulation in Bingham County. This brings the total regulated area in Idaho to 8,311 acres.  Continue reading

APHIS Removes the Mediterranean Fruit Fly (Ceratitis capitata) Quarantine Area in Half Moon Bay Area of San Mateo County, California

Effective October 4, 2018, the Animal and Plant Health Inspection Service (APHIS) and the California Department of Food and Agriculture (CDFA) removed the Mediterranean fruit fly (Medfly) quarantine in the Half Moon Bay area of San Mateo, California. Continue reading

NIFA Invests $4.7 Million to Address Critical Pest Problems

NIFA recently awarded 16 applied research and development grants to enhance the development, adoption, and implementation of innovative, ecologically-based, sustainable integrated pest management (IPM), technologies, tools, tactics and strategies that address regional and/or national IPM priorities. Among the projects funded include are the use of photobiology and lighting technologies for suppression of powdery mildew in strawberry production, developing techniques for management of Sclerotinia stem rot on soybeans, optimizing lures to detect invasive wood-boring insects, supporting homeowner IPM programs, and variable precision planting for maximizing weed suppression and yield increases in row crop systems. These grants are a part of NIFA’s Crop Protection and Pest Management Program, which addresses integrated pest management solutions for emerging weed, disease, and insect pests. Continue reading

APHIS Announces Schedule for Certifying Offshore Greenhouses That Will Ship Geranium Cuttings to the United States During the 2018-2019 Season

APHIS announced today that it will conduct annual certification visits in November and December to offshore facilities that wish to ship geranium (Pelargonium spp.) cuttings to the United States during the 2018-2019 season. During these visits, APHIS will confirm that the offshore facilities meet or exceed the “Minimum Sanitation Protocols for Offshore Geranium Cutting Production.”

APHIS must physically visit and certify all interested offshore facilities before December 31, 2018. Participating facilities must cover the full cost of these certification visits, including travel, salary, benefits, and overtime. The facilities will provide these funds through a trust fund established through a signed cooperative services agreement. Continue reading

Pesticide Program Dialogue Committee Meeting October 31, 2018 and Biotechnology Seminar November 1, 2018

EPA’s Office of Pesticide Programs (OPP) will hold a public meeting of the Pesticide Program Dialogue Committee (PPDC) on Wednesday, October 31, 2018, from 8:30 a.m. to 5:00 p.m. Additionally, on Thursday, November 1, from 8:30 a.m. to noon OPP will hold a Biotechnology Seminar. Both events will be held in EPA’s first floor conference center at One Potomac Yard South, 2777 South Crystal Drive, Arlington, VA 22202. Read the Federal Register notice announcing the PPDC meeting and biotechnology seminar.

The agenda for the PPDC meeting will be available on the PPDC webpage by October 19, 2018. The PPDC provides advice and recommendations to EPA on issues associated with pesticide regulatory development and reform initiatives, evolving public policy and program implementation issues, and science issues associated with evaluating and reducing risks from use of pesticides.
