As a Dust:
Control of disease
depends
upon thorough and complete
application
(a thin, uniform film) to both tops
and undersides
of leaves. Small canisters
may be used as a duster by partially
crushing and rapidly squeezing
the sides
in upright position,
or use a good pressure
duster
. Application
when wind is very light or absent, usually
early morning or evening, will prevent drift and loss of product to adjacent areas.
