Disease management in field crops is optimized by developing a long-term management program. Prevention and risk reduction through the integration of various cultural practices, including crop rotation, tillage, fertilizer management and pesticides, are the goals of an effective and economical disease management program. The starting point of any management program is the selection of locally adapted, disease-resistant cultivars. Because of the importance of this selection, tables providing descriptions of reactions of commonly grown cultivars to prevalent diseases have been included in this section. The lists are not all-inclusive because new cultivars may be released after the printing of this bulletin or lack of adequate testing prevents inclusion of information at printing. Updates are available through your county Extension office.
The remainder of this section is a compilation of recommended chemical disease control measures that were registered at printing. This is not intended to be an exhaustive index of all registered fungicides and nematicides. The information in this section is provided as a guide to available products, but does not substitute for or supersede the information found on the pesticide label of a specific product. Use pesticides only as the label directs. Trade names are included to aid in the identification of the specific active ingredient of a pesticide known to be effective. No discrimination against a similar product is intended or implied by omission. Mention of a commercial product does not constitute an endorsement by the authors or by their respective Extension services. Consult the pesticide label for any changes in rate, timing, handling, or registration.
