Spray Schedule for Home Orchards
ber of recommended materials and the time of application are a minimum.
Many commercial combinations of fungicides an(l
insecticides are available. If used as the manufacturer
recommends, these are effective in controlling the insects and diseases listed on the label.
To get good pest control, thorough spray coverage
of trees is necessary. It is hard to get complete coverage
with hand equipment, but it can be clone. Good cover-
age means thoroughly wetting the leaves, twigs, and
branches. When mixed with water, some chemicals such
as methoxvchlor, Sevin, wettable sulfur, and ziram tend
to settle out. Shake or stir the spray mixture frequently
during application.
Mature fruit will not have excess chemical residues
if you observe the proper interval between the last spray
and harvest, as indicated on the manufacturer's label.
All fruits should be washed before eating.
