PURE PARA-DICHLOROBENZENE 
For Peach Borer Control. 
Very powerful and effective remedy just 
coming into general use as a result of the 
experiments of the Department of Ento- 
mology. Should be applied September Ist 
to October 10th, according to latitude. 
Some growers prefer to make two applica- 
tions, the first being in the month of Juhe. 
One pound is sufficient for 10 to 80 trees, 
according to size. i{t is not advisable to 
treat trees under 4 years of age with Para- 
Dichlorobenzene, and apple trees should 
never be treated. 
Remove all grass, weeds and rubbish from 
around the tree, make a smooth, bare sur- 
face and about sixteen inches wide around 
the tree at the soil level. 
Remove any gummy exudation ahering 
to the crown or collar of the tree. 
After the ground is prepared, distribute 
the crystals of Para-Dichlorobenzene even- 
ly in a narrow circular band around the 
tree, keeping the inner edge of the band at 
least two inches away from the bark of the 
tree. 
After the crystals are placed on the soil 
around the tree cover them with earth, at 
first lightly so as not to disturb the chemi- 
cal, and complete .by nionuding the earth 
against the trunk of the tree until a cone 
shaped mass of dirt four or five inches deep 
has been made, tamping the dirt down with 
the back of the shovel. 
Use one ounce to a tree 6 years old or 
older; in case of very large tree, 144 ounces 
may be needed to form a satisfactory band. 
On trees four or five years old, use 4% to 3% 
ounces to a tree.

Scalecide is truly the complete dormant 
spray. Applied in the fall it controls scale 
of all kinds, bud-moth, pear psylla, peach 
leaf-curl, and fungous cankers. The delay-

scale, aphis, pear thrips, leaf miner, case 
bearer, leaf roller, European red mite, bud- 
moth, ahd fungous cankers. And in addi- 
tion year after year use of Scalecide in- 
vigorates the trees. Scalecide is guaran- 
teed to make a better ordhard than lime- 
sulfur. 
Scalecide is pleasant to use; it does not 
injure even the eyes. It is non-poisonous. 
It saves half the labor of spraying—a tank- 
ful of dilute Scalecide goés as far as two 
tankfuls of dilute lime-sulfur. Scalecide

spreader; saves more than three-fourths 
the freight and haulage. A fifteen-gallon
