Scab—Use one and one-fourth gallons of lime sulphur 
solution, two pounds of arsenate of lead to each fifty 
gallons of water. Spray first, just before buds open; 
second, repeat as soon ns petals fall; third, three or 
four weeks after petals fall; fourth, eight weeks after 
petals fall. 
Woolly Aphis (Schizoneura lanigera) — for above¬ 
ground colonies, spray with Black Leaf 40, 1 part to 200 
parts of water, or a tobacco decoction. The summer 
spray of 1 Vz gallons of lime-sulphur to 50 gallons of 
water will also kill them, but must be applied with great 
• force. 
For root-inhabiting colonies, remove the soil to a depth 
of about three inches, or sufficient to partially expose 
the roots; open a circle from four to eight feet in diame¬ 
ter, depending on the spread of the roots; distribute 
three to eight pounds of tobacco dust or use 10 per cent 
kerosene emulsion. Enough emulsion should be used to 
saturate the soil to a depth of three or four inches. 
Recent experiments have shown that kerosene emulsion 
may be used with success. Tobacco dust is of more 
value as a preventive and fertilizer. Badly infested 
trees should be treated with kerosene emulsion, applying 
this in April or May, but be sure to have the stock solu¬ 
tion properly made or it may injure the trees. 
BLACKBERRIES. 
Rust—Use a spray of sulphate of copper solution; one 
part to fifteen gallons of water before buds break. Use 
Bordeaux Mix t *ire (4-6-50) if Rust appears in spring 
or summer. 
GRAPES. 
Black Rot—Use Bordeaux mixture (3-4-50). Spray 
first, when leaves have expanded; second, just after fruit 
has set; repeat every two weeks until fruit is nearly 
grown. 
Borer (Prionus)—Its presence is manifested by the 
unhealthy appearance of the vine. Search must be made 
at the roots and the grub destroyed. 
Curculio—Use Bordeaux Mixture (3-4-50) adding two 
pounds of arsenate of lead. Spray, first, before bloom- 
ing; second, when fruit is about one-eighth inch in 
diameter; third, about first or fifteenth of July. 
Flea Beetle—Use two pounds of arsenate of lead, three 
pounds of lime to fifty gallons of water. Spray as buds 
are swelling and a second time about two weeks later. 
Leal Folder (Desmia funeralis)—Kerosene emulsion 
or paris green or arsenate of lead as a spray. 
Mildew—This can be controlled by Bordeaux mixture 
same as recommended for Black Rot. 
JAPAN PERSIMMONS, WALNUTS AND PECANS. 
Borer (Prionus)—These bore through the roots and 
usually destroy the tree, and must be carefully removed. 
Carefully examine collar of tree in winter and mid¬ 
summer, and apply lime-sulphur wash. 
Caterpillar (Catocala m®tosa)—Feeds on the leaves of 
pecans, and is sometimes quite injurious. Spray with 
paris green four ounces, lime one pound, to fifty gallons 
of water. 
Pecan Bud Worm (Proteopteryx deludana)—Spray 
the trees just as the buds are opening, with arsenate of 
lead, three pounds to fifty gallons of water, and two 
pounds of lime, and repeat application ten days later. 
If the worms appear again in June or July, repeat the 
treatment. This will also help control the pecan husk 
borer. 
Twig Girdlers (Oncideres cingulatus)—All limbs that 
have been girdled and have fallen must be burned at 
thus destroying all future broods of sawyers. 
White Fly—One and one-half gallons of Schnarr’s 
Insecticide to 100 gallons of water, or whale-oil soap 
1 to 1 % ounces to 1 gallon of water, or Thomsen Chem¬ 
ical Company’s lime-sulphur solution, 1 part to 25 parts 
of water. 
PEACHES AND PLUMS. 
Peach Tree Borer (Sanninoidea exitiosa)—The old 
method of worming peach trees in winter has been found 
ineffective, principally because the worms cause too 
much damage before being removed. 
In the spring remove the earth from about the body 
of the tree down to the crown, scraping off gummy ex¬ 
udations, and carefully search for the borer. For this 
work use a farrier’s knife or a tool especially made for 
worming peach trees. 
An excellent wash for borers is the following: One 
bushel of quicklime, 20 pounds of sulphur, 1 gallon of 
coal-tar, 50 gallons of water. Mix tar and sulphur in 
10 gallons of water and add lime. Stir well while 
slaking. When it is entirely slaked dilute the above to 
50 gallons, and apply this wash to the tree, allowing it 
to run well down upon the roots. As soon as it is ap¬ 
plied, draw up the earth to the tree so that it will form 
a cone about six inches above the level. A second ap¬ 
plication of this wash should be made during August. 
During the last of October remove the mound of earth 
from around the tree and thoroughly scrape the bark, 
as in the spring, and give another application of the 
wash. This is a vigorous treatment, but is effective in 
all cases. 
Black Knot in Plums — Cut off the affected branches 
below affected parts and burn to prevent its spreading. 
Spray with bordeaux mixture. 
Brown Rot on Peaches, Plums and Nectarines—As 
Brown Rot, Curculio and Scab work together, the same 
treatment is, therefore, recommended for all. 
For Early and Mid-Season Varieties—First: Spray 
the trees about ten days after the petals fall, when the 
calyces or shucks are being pushed off, using 1% pounds 
of tri-plumbic arsenate of lead and 3 pounds of lime to 
each 50 gallons of water. This is for the curculio and 
should be applied with a nozzle capable of throwing a 
fine spreading mist, covering the fruit and foliage with 
a very thin film of poison, but under no circumstances 
should the trees be drenched. 
Second: About twenty days later, or one month after 
the petals fall, spray the trees with atomic sulphur, 5 
pounds to 50 gallons of water, or self-boiled lime-sulphur 
(8-8-50). To this should be added IVz pounds of tri- 
plumbic arsenate of lead, and where arsenate of lead is 
used, 3 pounds of lime to each 50 gallons of the spray. 
This is the second treatment for the curculio and the 
first treatment for scab and brown rot. 
Third: About one month before the fruit is expected 
to ripen, spray the trees with atomic sulphur, 5 pounds 
to each 50 gallons of water, or with self-boiled lime- 
sulphur. No poison should be used at this time, and 
since the application is intended to prevent the develop¬ 
ment of brown rot during the month preceding the 
ripening of the fruit and during the picking season, the 
trees should be sprayed rather heavilv so as to coat the 
fruit on all sides. 
For Late Varieties—Date varieties should be sprayed 
with an additional application of atomic sulphur or self- 
boiled lime-sulphur about three weeks after the second 
treatment. This extra treatment is for the protection 
of the fruit from the attacks of peach scab, to which 
late maturing varieties are especially susceptible, as the 
interval between the second and third treatments would 
be much too long without it. 
Curculio—To prevent the depredation of this pest see 
remedial measures under Brown Rot and Scab. 
Peach and Plum Rosette—Root up and burn the af¬ 
fected tree as soon as the disease is observed. 
San Jose Scale—Same treatment as recommended for 
Apples. 
PEARS. 
Pear Blight—Cut off and burn all affected limbs. 
Careful pruning should be resorted to during the winter 
to remove all affected limbs and affected areas. Disin- 
fect the pruning shears after removing each branch or 
affected part. About a 4 per cent solution of formalde¬ 
hyde can be used for this purpose.
