Introduction

Skip to Introduction

This guide is published to help homeowners select fungicides, bactericides, and alternative products that will help prevent or manage common diseases in the landscape or garden. Chemical control options should be considered as part of an integrated approach to manage disease. The following cultural practices should also be included in an integrated management plan: 1) sanitation of tools and equipment, 2) supplying appropriate water, 3) rotating crops, 4) planting disease-resistant varieties, and 5) implementing other practices to promote plant health (for example, proper soil conditions, plant nutrition, and reduction of plant stressors). Common diseases of herbaceous ornamentals, woody ornamentals, lawns, fruit trees, small fruits, and vegetables are listed in the tables along with the most effective fungicides, bactericides, and alternative products available to homeowners for their management. Homeowners should take great care to read and follow the entire label of any product before treatment. The label indicates approved crops, safety precautions, timing, dilution instructions (if applicable), and application rates. Products listed here are sold at most garden centers. Product names can change, so it is important to look for the active ingredient if you cannot find the product name. Note that many products contain multiple active ingredients, targeting insects or mites as well as diseases.

These lists are not exhaustive, and the inclusion of specific products in this publication does not imply endorsement by North Carolina State University or discrimination against similar products or services not mentioned.
