A number of the tolerant varieties identified are already being grown at present or are being evaluated on a small scale by growers and industry personnel. The increased use of the identified tolerant varieties will definitely reduce the number of fungicide applications needed for control of these diseases, thus it will reduce production costs and contribute to environmental health. The effectiveness and impact of the combined use of tolerant varieties and the recommended scouting and forecasting procedure in the management of leaf blight diseases need to be demonstrated in collaboration with carrot growers. The latter will not only greatly reduce the number of fungicide applications needed per growing season, but may well eliminate the fungicide applications especially during a growing season such as that of 1999.en-USAgricultural IPMVegetablesCarrotsreport
