Methods and Guidance for Testing the Efficacy of Antimicrobials against Spores of Clostridium difficile

EPA is announcing the availability of test methods for evaluating the efficacy of antimicrobial pesticides against Clostridum difficile as well as regulatory guidance for pesticidal claims for those products. These test methods and guidance provide a framework for registrants who seek to make a claim for antimicrobial pesticide products to control these spores on hard, non-porous surfaces.

Under the Federal Insecticide, Fungicide, and Rodenticide Act, the registrant of an antimicrobial product with a public health claim is required to submit efficacy data to EPA in support of the product’s registration.   Continue reading

Specialty Crop Research Initiative (SCRI)

The purpose of the SCRI program is to address the critical needs of the specialty crop industry by awarding grants to support research and extension that address key challenges of national, regional, and multi-state importance in sustaining all components of food and agriculture, including conventional and organic food production systems. Projects must address at least one of five focus areas:

  • Research in plant breeding, genetics, genomics, and other methods to improve crop characteristics
  • Efforts to identify and address threats from pests and diseases, including threats to specialty crop pollinators
  • Efforts to improve production efficiency, handling and processing, productivity, and profitability over the long term (including specialty crop policy and marketing)
  • New innovations and technology, including improved mechanization and technologies that delay or inhibit ripening
  • Methods to prevent, detect, monitor, control, and respond to potential food safety hazards in the production efficiency,handling and processing of specialty crops.

Join the Northeastern IPM Center for its Third Annual IPM Online Conference on October 23, 2017

The third annual IPM Online Conference hosted by the Northeastern IPM Center (NEIPMC) will feature updates from active projects funded by the NEIPMC’s Partnership Grants Program. In addition, the online conference will have updates from IPM-related projects funded through the Northeastern Sustainable Agriculture and Education (NE SARE) Program and USDA-NIFA’s Applied Research and Development Program (ARDP) and Extension Implementation Program (EIP).

The rapid style conference will feature 5 minute presentations in which the speakers will discuss, show, or possibly sing! about 1 or 2 highlights from their projects. The purpose of the conference is to increase collaboration and awareness about current IPM-related research and extension in the Northeast in a fun way. Continue reading

Predatory insect may help with whitefly control

Scientists at the University of Florida have found an insect predator that may help greenhouse tomato growers manage populations of the sweetpotato whitefly when used as a piece of an integrated pest management system.

Bemisia tabaci, also known as the sweetpotato whitefly or silverleaf whitefly, attacks a range of plants, including sweetpotato, squash, tomato and poinsettia. The biotype B species has been established in the United States since the late 1980s. It transmits Tomato yellow leaf curl virus. Young tomato plants infected with tomato yellow leaf curl virus are stunted and unproductive. Continue reading

Southern nursery group shows growers how to get the biggest bang for their buck with weed control

Most of us are used to seeing weeds in our yards or flowerpots, but not in the plants that we buy in the store. Nursery crop growers and workers go to great lengths to make sure that the plants we buy are weed free when we pick them up. That service comes at a great cost to the grower, however, so Joseph Neal at NC State University sought to remove some of the burden by teaching nursery owners more efficient and economical ways to weed their container plants.

Weeds are a serious problem for nursery crop growers, not just because they reduce marketability of their container plants, but also because they can inhibit plant development. Just one large crabgrass plant in a container with Japanese holly, for instance, can reduce the weight of the holly by as much as 60 percent. Nursery crop producers use between three and six applications of preemergence herbicides per year, and often must still hard weed after that. The cost of hand weeding is between $500 and $4,000 per acre per year based on labor costs. Continue reading
