Tools for a PMSP for New Jersey Carrot

Carrot was chosen by our NJinPAS Advisory Committee as the next candidate for a PMSP (2004) due to a significant carrot weevil problem. Rutgers Cooperative Extension integrated pest management scouts have continued to work with local carrot growers in monitoring pest activity during the growing season. Extension Vegetable IPM Coordinator Joseph Ingerson-Mahar  worked through our IR-4 liaison, Gerry Ghidiu to assess and formulate a pest management strategy for a continuing severe pest problem in carrot that first occurred in 2001.  This issue was brought to the attention of the Advisory Committee and it was unanimously agreed that carrot should be the next crop.  Joseph Mahar completed a 'Crop Profile for Carrots for New Jersey' as a precursor to the PMSP; it was posted to the NJinPAS Crop Profile webpage at http://www.pestmanagement.rutgers.edu/NJinPAS/CropProfiles.htm on February 25, 2003.

Joe Mahar and Kris Holmstrom provided the technical tools below for the Work Group to use.  See 'Tools' below.

There was a Carrot PMSP Work Group Meeting at the Rutgers Agricultural Research and Extension Center in Bridgeton, New Jersey on Tuesday March 16, 2004. The Work Group was led by Joseph Ingerson-Mahar, Vegetable IPM Coordinator for Rutgers Cooperative Extension. The participants in the Work Group included sixteen commodity and technical specialists: scouts, growers, a leading processor (Campbell), IR-4, and researchers and specialists in entomology, diseases, weeds, and pest management.

The Work Group identified what the most serious threats are to the production of carrots in NJ, as well as what are the most pressing research, regulatory, and educational needs.  A draft PMSP Plan was used as a working document at the meeting. 

This draft was revised according to the Work Group’s input at the meeting, and is posted below in 2 formats:

The final Pest Management Strategic Plan for Carrot for New Jersey has been revised to address all comments and was released on January 29, 2006.

USDA CSREES Risk Avoidance and Mitigation Program (RAMP)GRANT – A Partnership Among Eastern US Carrot Stakeholders to Develop and Implement IPM

Carrots are an important part of the diets of young children and infants, and consumers have concerns regarding pesticide use and the potential for residue in baby foods as well as other processed and fresh products. Collectively, Michigan, Wisconsin, New Jersey, and New York provide nearly half of all carrots used for processing in the U.S. However, the eastern U.S. carrot industry is at a critical juncture because of many of the currently relied upon pesticides face an uncertain future as a result of the Food Quality Protection Act (FQPA) and processor concerns. Without replacement products or management strategies to offset the loss of one or more pesticides at risk due to FQPA, growing carrots in the eastern region of the U.S. will not be profitable.

Research in New Jersey dealt specifically with:

  1. controlling foliar blights using the Tom-Cast disease forecasting program for optimizing fungicide applications integrated with cultivar resistance;
  2. determining the efficacy of reduced risk fungicides as compared to standard fungicides in controlling foliar blight throughout the season; and
  3. evaluating carrot cultivars for foliar disease resistance. This research was conducted over two growing seasons (2002 and 2003).

These studies are summarized in four reports and are provided below.

Rutgers Agricultural Research and Extension Center (RAREC) staff conducted studies in 2002 and 2003 comparing the efficacy of a Bravo only fungicide program with a Bravo /strobilurin alternation program (with and without a disease forecasting schedule) applied to processing carrot varieties of differing leaf blight susceptibilities.

  1. Fungicide Study 2002
  2. Fungicide Study 2003

Rutgers Agricultural Research and Extension Center (RAREC) staff conducted studies examining the horticultural characteristics, yield and foliar disease resistance of 10 and 17 separate processing carrot varieties respectively in 2002 and 2003.

  2. Resistant Variety Study 2003
