ENEMIES OF FRUIT TREES AND PLANTS 
Only a few years ago little or nothing was known about fungous diseases, and almost 
nothing about the insects that trouble the fruit-grower. But we know now the life history 
of all the common insects, as well as fungous diseases, and know how to combat them at 
each stage of their life. It is only necessary to follow directions, and be prompt and thor- 
ough, to insure success. A man will spend weeks cultivating his corn field, that will barely 
yield a crop to cover the labor, and begrudge a week's time to his fruit that will yield him 
returns running into hundreds of dollars' profits per acre. 
INSECTS 
There are some insects that escape our attention entirely unless we look closely. Among 
these are the gnats, mites, scale lice, and the ordinary plant-lice. These are all insects 
that live by sucking the sap of the plant for food, and have to be combated with some 
mixture that dries on them, stopping up their breathing pores, which are arranged along 
their .sides, or else by their caustic action eats away their tissues and destroys them. They 
have a great many natural enemies. Among them are the Ichenumon Fly — a fly looking 
much like a tiny wasp — and the Lady Bug. The insects that eat the leaves for food, .such 
as the Potato Bug, the Apple Tree Tent Caterpillar, etc., are killed by poisoning their 
food, and some form of arsenic has been found best for this purpose. 
FORMULAS FOR SPRAYING 
PARIS GREEN. 1 lb. Paris Green, '>, lbs. hme, 100 gallons water. Spray upon foliage 
to kill elm leaf beetle and all biting insects. Commonly used with Bordeaux Mixture. 
KEROSENE EMULSION. 2 gals, kerosene, 14 lb' common soap, 1 gal. water. Dissolve 
the soap in hot water, add kerosene, and churn all together until a white creamy mass is 
formed, which thickens on cooling. Dilute nine times before using. This is to kill the 
sucking insects. 
LIME SULPHUR SPRAYING MIXTURE. 14 lbs. lime, 14 lbs. flowers of .sulphur, 40 gals, 
water. Put about one-third of the water in a receptacle, then the sulphur and lastly the 
lime, and stir constantly until the lime is slaked, then boil for an hour, or until the mix- 
ture becomes a reddish amber color, which indicates the sulphur has been dissolved. Add 
balance of water, and it is ready for use. Only best quality of fresh lime should be used. 
This mixture should be applied while fresh, and only on dormant trees, to kill San Jose 
scale insect. 
BORDEAUX MIXTURE. 4 lbs. copper sulphate, 4 lbs. fre.sh Hme, 40 to 50 gals, water. 
Dissolve the cojjpcr sulphate in hot water, or from a coarse bag suspended in cold water; 
slake the lime separately. Dilute the former to about 20 gals., into which pour the lime 
diluted to about 10 gals., stirring the mixture; dilute further to form the 40 or 50 gallons. 
Stock solutions of the copper sulphate or lime, rate 1 lb. to 1 gal. water, can be kept in- 
definitely. Bordeaux Mixture is for fungous diseases, and by adding Paris Green to it. it 
can be made a remedy for both fungous and insects. 3 ounces of Paris Green to the barrel 
is enough. The Bordeaux mixture, when used on such plants and trees as the peach 
and Japanese plum, should only be used about half the above strength, as the foliage is 
injured by the stronger mixtui-e. 
We aim to keep on hand an up-to-date line of SPRAYING IM- 
PLEMENTS, including Pumps, Hose, Nozzles and other equipment for 
spraying. Catalogue of Spraying accessories sent on request.
