Among the evidences of insect injur-
les is the turning brown and dying Of
the tops of peach trees. In some cases
rot Is blamable for this, but the injury
usually results from small green
caterpillar. the lGrva of the peach twig
borer. This insect, while a common
one in some sections of the country, is
not very well known in New Jersey.

quarters. This pest can be controlled
by spraying with paris green about
the time the foliage starts in The

The pest is the worst during hot
weather. About the only way TO save
the trees is TO stimulate early growth
by irrigation, and forcing by the use
of quick acting fertilizers.

The effects OF Insecticides on foliage
have been studied quite carefully One
rather peculiar face is that young and
tender foliage will stand stronger in
secticides than older leaves. Paris
green tends to choke the leaf or to
close the breathing pores. Crude pc
troleum should never be used. for the
paratfin that it contains fills up the
pores. II has been frequently observed
in orchards that no bad effects follow
the application oS paris green for some
days and even weeks. Then suddenly
the leaves appear burned, This is eX-
plalned by the fact that soon after ap-
plication the paris green becomes dry.
While in this condition no injury oc-
ours, but when moisture appears
through humidity or rain, the solu-

are burned. AS an insecticde paris

On some varieties of pears the San
Jose scale, which appeared very abun-
dant in spring, did not show any in
crease by autumn. This proves that
under certain conditions the San Jose
scale can be easily conGrolled. or there
are conditions under which Il does not
thrive. The pest known as the Paris
scale seemed to be abundant, ard is
about as bad as the San Jose.

most serious injury from this pest is

The pea louise is abundant in many
sections, and the only practical method
of controlling seems to be in raising
early varieties. IL the crop can he

will result. Sweet peas are just as
badly affected as garden or field crops.
For small lots a strong decoct.on o.
