Fungicide Spray Schedule
for Home Garden Tree Fruits
Jennifer L. Chaky, Extension Educator, Plant Pathology
John E. Watkins, Extension Plant Pathologist
Growing tree fruits in the home garden can be a very
enjoyable experience, and with proper management, can
provide many years of enjoyment. Success in growing tree
fruits depends on following an approach known as
integrated pest management, or IPM. In this management
program, variety selection, cultural practices and chemical
means are used to prevent or reduce losses due to diseases
or insects. Efforts spent in initial planning by selecting
hardy cultivars with resistance can save much time in the
future and will minimize the need for other management
strategies.
Cultural practices, such as rotation, sanitation, and
planting resistant varieties can be effective in managing
some diseases, but with other diseases these measures
may not be sufficient. When variety selection and cultural
practices are not sufficient to control disease problems,
fungicides may be applied to provide adequate control.
When used correctly, chemical controls are safe for the
environment, the applicator and also the consumer. It is the
responsibility of the applicator to properly use, store and
dispose of fungicides and other pesticides. Effective
chemical control of diseases depends on use of the proper
chemical at the correct time and thorough coverage of both
fruits and leaves with the product. Proper timing and
chemical application is necessary for effective disease
control.
Reading and following the product label is an important
part of any fungicide program. It includes directions for
mixing and applying the product, safety information and
waiting periods from last application to harvest. By following
an IPM approach, which includes the responsible use of
fungicides and other pesticides, the number of enjoyable
years that one can expect from a home tree fruit planting
can be considerable.
