How to treat brown rot in apricots?
If brown rot has been a chronic problem in your garden and the cultural methods discussed above have not proven successful for control, consider using fungicides. Select products that are labeled for use on apricots, cherries, peaches and/or plums and that contain captan, myclobutanil or propiconazole. To prevent blossom infections, make one application when approximately 10% of flowers are open. To prevent fruit infections, begin making applications three weeks before anticipated harvest, particularly if there is wet weather. When applying more than one application, DO NOT use myclobutanil and/or propiconazole for all treatments as these active ingredients have similar modes of action; excessive use of these active ingredients can select for fungicide-resistant strains of brown rot fungi. Instead, alternate use of these active ingredients with use of captan or only use captan (which is not known to have problems with resistance development) for control. Also consider insecticide treatments to manage insects that can damage fruits and provide entry points for brown rot fungi. See University of Wisconsin Extension Bulletin A2130, “Apricot, Cherry, Peach, and Plum Pest Management for Home Gardeners” (available at http://learningstore.extension.wisc.edu) for suggested insecticides and timings of applications. Be sure to read and follow all label instructions of any fungicides and insecticides that you select to ensure that you use these products in the safest and most effective manner possible. Be especially careful not to apply any pesticides closer to harvest than is allowed on the label.
