IeTMI ToloaMo FerwalM toy Pro#. Maynard, Every fruit and plant has its peculiar insect enemies and fungous diseases. Progressive farmers, gardeners and fruit growers are provided with spraying machinery for overcoming these pests, and spraying is as much routine work as is cultivation or fertilizing. For fungous pests, because of cheapness, effectiveness and lasting qualities, the bordeaux mixture has superseded all other mixtures.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 pound*, is then slaked slowly by adding small quantities of water until thoroughly dissolved. When

cooled, the Hme wash is poured through a fine mesh sieve into the dissolved copper sulphate. To the mixture is then added 25 to 50 gallons of water. Destruction to fungous is probably caused by the copper, which is held in place by the lime. Should the bordeaux mixture disfigure the fruit, the atnmoniacal carbonate of copper should be used and applied often, as it washes easily. Formula: Copper carbonate three ounces, ammonia enough to dissolve the copper, water 40 gallons.

Paris green and kerosene emulsion are the insecticides in most common use. Paris green effectually destroys chewing or leaf-eating insects, and is less liable to injure foliage than london purple. UseJn water, one pound to 200 gallons. If lime is added, or the paris green added to the bordeaux mixture, use one pound to 50 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 vet 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, Moss. Agr.
