Conclusions

This report presented the result of a pesticide use survey given to New York State carrot growers summarizing their pesticide use and other data for the 1996 growing season. New York State ranks tenth nationally in carrot production, producing 500,000 cwt. in 1994, valued at $5,287,000 (1994 Agricultural Chemical Usage:Vegetables, p.27). Growers reported growing carrots on 800 acres.

Carrot growers in New York State face a variety of pest control problems. Some of the problems that concern them are listed in Table 4: Difficult to Control Pests. Nematodes and Rhizoctonia are mentioned as serious and troubling pests. Oxamyl, the only practical chemical treatment for the control of root-knot nematode, was used on 238 total acres; which is approximately 25% of the carrot acreage reported. Another problem requiring yearly management is foliar blight caused by Alternaria and Cercospora species.

Rotation with grain crops or other non-host crops can reduce the severity of root-knot nematode (Cornell Pest Management Recommendations for Commercial Vegetable and Potato Production, p.70). Crop rotation was commonly mentioned as an effective alternative pest control practice (see Table 2). Although the root-knot nematode will remain a challenge for New York State carrot growers, they are utilizing both chemical and non-chemical techniques to combat this pest.
