Pest Management Solutions for Specialty Crops and Specialty Uses
Greetings!

During September, we held the first ever IR-4 Virtual Workshop! Final priority results are posted on the workshop page.

Management of Phytophthora in citrus with fluopicolide and spider mites in peanuts with fenpyroximate were the highlighted food crop successes, and EPA granted residue tolerances for saflufenacil and exempted Psuedomonas fluorenscens strain ACK55 from tolerance. For environmental horticulture crops, a summary for F6123 crop safety was prepared, and we described characteristic of and crop management issues for the popular foliage plant hosta.

Links to these recent successes for the Food and Environmental Horticulture Programs are below.

IR-4 is seeking an Associate Director of Regulatory Sciences at the IR-4 Headquarters at NC State in Raleigh, NC. The position description is located here.
