SEASONABLE SPRAYING

MIXTURES

Following are the formulas recoin* mended by the Government Agncul ural Department for sprayingmixtures suitable the winter mouths :

UoRDEAUX IVIIXTUKK ( Winter Formulae)' For Apple-scal>, Pear-scab and Parasitic Fungi generally, especially ■those attacking the peach : In the case of the peach, if possible ispray twice, the first time just after the leaves have fallen, and again just as the buds begin to swell, taking special care to cover the young wood. Proportions — lOib sulphate o{ copper, !oib fresh roche-lirne, and 40 gallons water. Preparation — Dissolve the 101b sulphate of copper in 20 gallons water, slake the 101b lime slowly, and make up to 20 gallons; strain this rank of lime into the solution of sulphate of copper, stirring briskly. This should be used within eight hours of mixingl, otherwise its value as a fungicide is largely depreciated. ' Red-oil Emjlsioks (Winter Formulae) For Mussel Scale, Red Spider, etc., on deciduous fruit trees : To be used when trees are quite dormant. Early application is recommended — say, July or August. Spraying with oil late in the season when, the buds are swelling is apt to destroy them. Any red oil, provided it has a specific gravity of over 900, is suitable for winter spraying. Proportions — 4lb sppcial soft-soap, 4 gallons red oil, 68 gallons cold water. Preparation—To make the emulsion put the soap into a tub ana pour 2 gallons of boiling water over it. Stir briskly to a good lalhpr and add the oil. Ndw make use of your spray-pump; put both delivery and suction suds of spray-pump hose into the tub and work the pump steadily ] for a few minutes—this will cause a perfect emulsion ; now add the 66 gallons of cold water and the mixture ] is ready for use. Some growers prefer to use the red oil in the proportion of 1 gallon of emulsified oil to 10 or 12 gallons \ of water, instead of: the proportion of , I to 17: * ] . Woolly Aphis—-Paint any colonies \ which may escape the winter spray with red-oil emulsion undiluted. 1 Lime- Salt -axd- Sulphur For Mussel Scale etc. A good, , general winter wash for deciduous fruit trees. ■ Proportions—JOlb quicklime, 15lb salt, 201b sulphur, 60 gallons water. 'c Preparation—First boil 20lbs lime ] and 201bs sulphur in 20 gallons c water until both lime and sulphur are dissolved. This will require about A one hour. When sufficiently done, the mixture will be of an amber ' colour. Be careful to use an iron boiler: as this preparation will destroy , any vessel or spray-pump made of , coy, er. The remainder of the lime \ should then be slaked into a barrel \ with hot water. Add the salt and ' stir briskly. Mix the two lots to gother with enough water to make 60 gallons, and apply hot if possible, \ using a good pump, and taking '. special care to cover the youug wood.. ; The best results are derived by ' spraying just before the buds begin ; to swell. As the liquid is very [ corrosive, a cup shaped piece of rretal should be attached to the ; director a few inches below the < nozzle. This will, in a measure, : chock the material from running ! down to the hands. Well-gresod , leather gloves should be used, or , else the hands should be protected by being well greased.

Emulsified Red Oil

The formula suggested by the Biologist for emulsifying the red oil is :—

1 gallon cod-oil, crude carbolic acid, U-lb caustic potash.

Heat in an iron boiler to temperature of 280 F., and then pour into 10 gallons of denatured oil. Add 2 gtJs of cold water. For spraying, diiuto with sufficient cold water to make a mixture containing 6 per cent of oil, or abouf- one part of oil to seventeen parts of wator. Tins formula enn also be used for emulsifying ■ the natural oil, hut if lib of resin bo first dissolved in the oil the results will be more satisfactory.

Many dealers now sell emulsfied red oil, needing only the addition of seventeen (17) parts "of water to be ready for use.

As Sergeant Larke patrolled the park, He heard two sneezes in the dark. With staff gripped tight, flashed his light, His stern tones echoed through the night, " Kape ahf th' grass! ye coople there : Yure dith ay cowld yell yet, f'r shure ! Come ! hurry home, ye love-sick pair, And both take Wood's Great Peppermint Cure."
