The San Jose Scale was introduced
into this country in the early seventies

Come ''bugologists'' claims that the
mother scale from the nrst Of Tune

pect several million descendants the
next year.
Until the scale II some two weeks

Perhaps the most extensively used
4 remedy 10 the sulphur lime or sulphur
salt lime wash. Either formula when
properly compounded = effective IN
killing the scale.
These sprays have also proved to be
such an excellent fungicide a. to be
! worth far more than its cost In

cleaning away fungus. and stimulating

The efficiency OF the sulphur-lime

Briton Of Connecticut. has shown
conclusiveiy that after II has been
placed on the tree its efficiency re-
mains for months. He found more
dead scale at the end OF two weeks
than at the end OF one and more dead
at the end Of four months than at the
i, end OF three.
II has been said that II this spray
stands over night It looses Its strength
and Il worthless. This u . mistake
that has bean proven by practical fruits
growers and horticulturists, not only
IN our own state but various other
states IN the union. III
