Green Peach Aphis 
Oyster Shell Scale 
Peach Leaf Curl 
Pear Leaf Blister Mite 
Lime-Sulphur 
Winter strength 
Apply while buds are swelling to Apples, Pears, Peaches, Plums 
and Cherries and small fruits, using the winter strength lime-sul- 
phur, drenching all parts of the tree. 
Test both the commercial and home-made lime-sulphur with hy- 
drometer before using to secure the correct strength. The tree 
must be completely covered with winter strength lime-sulphur 
when spraying for scale insects. Coat every portion from ground 
to tip of twigs. 
Strawberry Leaf Blight 
Lime-Sulphur 
Summer strength 
Apply when new leaves start. 
Repeat every 10-15 days until flowers appear. Bum leaves as 
soon as crop is harvested. 
Thrips 
Nicotine Ext. (40Vr ) % pint 
Water 100 gals. 
Soap 2 to 6 lbs. 
The period for effective spraying against adult thrips is during 
the time when the buds are swollen and partly open, and until they 
are entirely open at the tips. Spray for the larvae after the petals 
drop to reduce the numbers of insects for the following year. 
Apple Scab 
Black Rot of Apple 
Brown Rot of Prune 
Bud Moth

Codling Moth 
Lime-Sulphur 
Summer strength 
and 
Arsenate of Lead 
3 lbs. to 50 gallons 
First application. Just before blossoms open, for apple scab and 
various leaf-eating insects, use lime-sulphur solution (32<^ Beaum6) 
diluted with forty parts of water, with two to three pounds ar- 
senate of lead to forty gallons. May be omitted if insects are few 
and weather is dry. 
Second application. When blossoms are about two-thirds off, 
give same treatment as (2). This is the most important spraying 
for apple scab and codling moth. Should never be omitted. 
Third application. About two weeks later repeat (2) if weather 
is favorable for apple scab; that is, moist and warm. 
Fourth application. About first week in August repeat (2) to 
prevent late infections of apple scab and to control second brood 
of codling moth. 
PEARS 
Spray as for apples. As foliage appears to be more susceptible to 
injuries by the spraying mixture, dilute concentrated lime-sulphur 
solution (32® B.) in the proportion of 1 to 50 and apply the 
liquid in minimum quantities, using nozzles with fine apertures. 
For life history of codling moth, write Experiment Sta., Geneva. 
Canker (N.Y. Apple)

See Arsenate of Lead for combination spray. 
Grape Rot and Anthrac- 
nose 
Bordeaux Mixture 
5-5-60 formula 
Apply when leaves are half grown ; just before blossoming ; 
when fruit has set. 
Repeat once or twice at intervals of two weeks. If later applica- 
tions are necessary, use ammonical copper carbonate solution. 
Plum Curculio 
Arsenate of Lead 
PLUMS 
First application. When “husks” or calyxes drop, spray vrith 
arsenate of lead, 3 lbs. to 50 gals, of water for the curculio. For 
leaf spot on European varieties use bordeaux mixture 5-5-50 with 
arsenate of lead. 
Second application. For leaf spot repeat spraying with bor- 
deaux mixture about ten days later. 
Spray Japanese varieties of plums as directed for peaches. 
CHERRIES 
Spray as for plums for San Jose scale and the curculio. 
PEACHES 
First application. When “husks'* or caly.xes are dropping use 
two pounds of arsenate of lead, to fifty gallons of water for the 
curculio. The self-boiled lime-sulphur mixture may be used as 
carrier of the poison to control also brown rot and scab. 
Second application. Two or three weeks later use 8-8-50 self- 
boiled lime-sulphur mixture and two pounds of ai’senate of lead. 
Third application. About one month before finiit ripens repeat 
treatment with self-boiled mixture, omitting the poison. 
AphLs 
on fruit trees 
on garden crops 
Leaf Hopper 
Oyster Shell Bark Louse 
Red Spider 
Woolly Aphis on Branchs 
Kerosene Emulsion or To- 
bacco Black Leaf 
These are contact insecticides and should be applied to exposed 
and tender bodies of young. These are all sucking insects and 
food poisons are of little value. 
Be sure to penetrate covering of woolly aphis ; be thorough, do 
not allow any to escape. 
Peach Brown Rot 
Peach Scab 
Lime-Sulphur 
Self-boiled 8-8-50 
Spray four w-eeks after blossoms have fallen, again in three

Apple Cankers 
Aphis Eggs 
Pear Leaf Blister Mite 
Red Spider Eggs 
Tent Caterpillar Eggs 
Woolly Aphis 
Lime-Sulphur 
Winter strength 
Spraying in spring before buds open may be substituted for this 
for combating insects and fungus pests. However, it may be de- 
sirable to apply in fall on account of rabbits. 
Grape Mildew 
Flowers of Sulphur 
For mildew on grape use finely pulverized sulphur. Dust the 
ground and vines freely during a warm, bright morning when 
the slightest attack of mildew is suspected. This should not be 
applied while the weather is damp or the vines w’et. 
Tussock Moth 
Band Trees 
Band trees with tanglefoot or strips of raw cotton, binding it 
in the middle, leaving band loose above or below. Do not apply 
sticky preparations directly on bark of trees. Use bands during 
June, July and Augu.st. Remove egg clusters which appear in 
masses as a white froth. 
Crown Gall 
Fire Blight 
Raspberry Cane Blight 
Strawberry Crown and 
Root Borers 
Leaf Rollers 
Destroy infected parts 
See notes 
Crown Gall is a bacterial disease of root or crown of trees. All 
infected trees should be destroyed. Keep a constant lookout for 
thU trouble. 
Fire Blight Bacteria may extend below discolored or blackened 
region, hence cut should be made about one foot below. Disinfect 
knife and wound with mercuric bichloride one part to 1000 parts 
of water. 
Strawberry plants should be dug up and burned before May 1 
to destroy insects before beetles escape to lay eggs. 
For straw'berrv leaf roller burn too as soon as crop is gathered.
