FIGHTING INSECTS.

Some Valuable Formula* Fnrnlihed by Prof. Maynard. Every fruit and plant lias its peculiar insect enemies and fungous diseases. Progressive farmers, gardeners and fruit growers are provided with spray- ‘ ing machinery for overcoming these I pests, and spraying is as much routine work as is cultivation or fertilizing. For fungous pests, because of cheapness, effectiveness and lasting i. , the bordeaux mixture ha., si. ... ..o all other mixtures. To make it, four pounds of copper sulphate or blue vitriol are dissolved in two gallons of hot water; or, suspended in a coarse rack in a cask of cold water it will dissolve in a few hours,. Caustic or -quicklime, four pounds, is then s’r.lteci slowly by adding small quantities of water until thoroughly dissolved. When

Dcetructic . to fungous is probably by copper, which is held in place by the lime. Should the bordeaux mixture (.luf;;"irc the fruit, the animoniacal carbonate of copper should be used and applied often, unit washes easily. Formula: Copper carbonate three ounce s, ammonia enough to dis* i solve the copper, water 40 gallons. Paris green and kerosene emulsion arc the insecticides in most common use. Paris green effectually destroys chewing or leaf-ea:Jng insects, and is less liable to injure foliage than london purple. Use in water, one pound to 200 gallons. If lime is added, or the paris green added to the bordeaux mixture, use one pound to 60 gallons. For sucking insects, the kerosene emulsion is unequaled: Dissolve a half-pound of bar soap in two.gallons of hot water, and while, hot add two gallons of kerosene oil and stir until a lard-like substance is formed. When used, dilute ; with water to 15 or 25 gallons. Insects and fungous growths appear together, hence, many combine paris green with the bordeaux mixture, saving half the cost of application. For applying, the pump selected should throw a heavy Stream, with considerable force, and yet work with ease. The illustration herewith shows a powerful pump and suitable sprayer for all ordinary crops. ■; The barrel is readily mounted on any form of wagon. -Prof. S. T. Maynard, .Mass. Agr.
