Satisfactory results IN spraying de-
pend upon the careful performance OF
the work. Carelessness VIII result In
dissatisfaction. a good pump and plen-
~ OF hose, extension pipe and iine noz-
2le are essential
The most experienced and successful
sprayers In Utah are unanimous In the
opinion that the spraying should be
continued through July and at least up

Cleanliness Is the first step toward

sources OF great production Of worms

best dsnfectants

ure against San Jose scale and as an
