the spray tank. In larsc operations it 

 is best to prepare stock solutions of both 

 bluestone and lime. The bluestone may 

 be dissolved at the rate of one pound 

 per sallon of water. The lime may also 

 be slaked, but not too far in advance of 

 the time necessary to use it. By having 

 a sufficient number of barrels for stock 

 solutions, one man can easily keep three 

 or four power spray outfits supiilied with 

 the Bordeaux mixture. An elevated plat- 

 form upon which the mixing may be done 

 will save a great deal of time. As little 

 hand labor as possible should be the rule. 

 and all that should be necessary in a well- 

 appointed mixing plant should be simply 

 opening and closing valves or gates. A 

 scale to weigh the materials used should 

 be a necessary part of the equipment.

First slake the lime, stir the poison 

 into a thin paste with a little water, add 

 this to the lime, then strain the mixture 

 through a sieve into a tank containing 

 the required amount of water. If it is 

 desired to spray for both fungi and in- 

 sects on peaches or other tender foliage. 

 200 gallons of water should be used. Jl 

 is necessary to keep this mixture well 

 agitated while spraying.

The Paris green and lime are thorough-

 appears; then add the above to each 50 

 gallons of Bordeaux mixture made ac- 

 cording to the 5-5-50 formula, given above. 

 The reason for usinp; the resin mixture 

 is to cause the Bordeaux to spread and 

 adhere better. The Resin-Bordeaux 

 should be applied with a good spray 

 pump and a nozzle giving a very thin 

 fine mist spray. Keep the mixture well 

 agitated, and before using remember that 

 it should be carefully strained so as to 

 keep out all material which would tend 

 to clog the nozzle.

FUNGICIDES AND CONTACT INSECTI- 

 CIDES FOR SUCKING INSECTS 

 Liquids 



Lime-sulphur is easily the most im- 

 portant insecticidal spray now used and 

 its fungicidal properties make it even 

 more useful to the orchardist. It is 

 especially valuable for controlling scales, 

 insects and fungi on deciduous fruit 

 trees, though if properly weakened it 

 may also be used as a summer spray, 

 particularly for the citrus and almond 

 spiders. 



Formerly lime-sulphur spray was a 

 home-made product, but today the com- 

 mercially prepared product is so supe- 

 rior to the home-made inixtures that the 

 latter have almost ceased to exist.
