Lime e-Sulphur solution: strong lime I sulphur solution is used as a dormant 1 tree treatment for the control of scale insects and certain diseases, and in
 much more dilute condition as a spray l on trees in foliage for the control of various fungous diseases. Many grow 1 CTS prefer to purchase the commercial article. which comes on the market of
 a specific gravity of about 33 degrees I Baume. This is used at the rate i of 1 gallon to or gallons of water for winter spraying, and at the rate | of 1 1-2 gallons of water for use on apple and other pome fruits as sum- l mer fungicide. In summer spraying | the arsenate of lead and 40 per cent.
 nicotine sulphate is added to the dilute | lime-sulphur solution, thus permitting the treatment of sucking and biting ] insects and fungous diseases. Con- centrated lime-sulphur solution can
 be made at home, which practice is followed by numerous growers. Those l interested in this matter should write to the Department for more explicit i information than is feasible to give | here.
 Nicotine: Nicotine is used for the | control of certain sucking insects as ! l psylla, etc. This product comes on the market of various grades, but the grade known as 40 per cent nicotine | sulphate is mostly employed. This | may be used alone in water to which has been added a little soap, or in | lime-sulphur and arsenate of lead, | or in Bordeaux mixture and arsenate
 of lead sprays. It is employed at the 1 rate of from 3-4 to 1 pint per hundred | gallons of spray.
 | Bordeaux Mixture: Bordeaux mis-
 ture is composed of pounds of blue
 stone Cooper sulphate) and pounds | of stone lime to 50 gallons of water.
 Tor early summer spraying the amount l of blue stone may be reduced to \ poundh to lessen risk of injury. To
 make Bordeaux mixture for use in an 1 ordinary barrel sprayer, dissolve 5 sto
 4 pounds of blue stone in 25 gallons | of water and in a separate containeI slake pounds of stone lime and dil- ute to 25 gallons, then pour the solu- tions simultaneously through a strain
 CT into the spray tank. Stock solu. l tions, especially where large quanti- | ties are to be used, are desirable
 since they save time. A stock solution
 of bluestone is made by dissolving il
 at the rate of one pound to one gal l lon of water. The bluestone shoulo be suspended in sack in the upper part of the barrel or other containel
 so that it is just beneath the surface
 of the watsr It will be dissolved ii
 left for few hours in cold water
 and more rapidly in hot water. 4
 stock solution of lime may be made by slaking the lime in a little water
 and then diluting so that each gal
 of water contains one pound of lime Just before the stock solutions art used they should be stirred thorough from stock solutions, it is only neces ly. To make up Bordeaux mixture sary for or gallons of the stool solution of bluestone to be poured in to a suitable container and 4 gallons I Of the stock solution of lime into { separate container, dilut.ng each to 2! gallons and then pouring them simul taneously into the spray tank. Com 4 mercial Bordeaux may be used il place of the homemade product.
 Il Self-boiled 1ime-sulphur mixture The self boiled lime-sulphur mixtur
 consists of pounds of sulphur ant i 8 pounds of good stone lime to eacl 'E5O gallons of water and is made a } follows: The lime is placed in
 barrel and enough water added t
 nearly cover it. As soon as the linn
 begins to slake the sulphur shoul' be added. Water should be adde,
 from time to time to form a thorough
 ly thick paste which should be con stantly stirred. As soon as the Jim is entirely slaked, enough water shoul be added to cool the mixture, which then ready to be strained into tn spray tank. where it should be dilut ed to the proportions given above. Tn
 sulphur used may be in the form (
 flowers" flour" or 'commercis s ground" and should, if necessary, b : run through a screen to break u

 g Spraying Apparatus.
 }, For the proper application of spra. r some form of spray pump with sui ,. able nozzles is absolutely essentia r Most spray outfits are supplied wit It spray rods permitting the operator
 direct the spray as desired. IT l, hose should be of sufficient length l. permit convenient spraying.
 e Spray outfits vary in size from sms bucket pumps to gasoline power ou l. fits for large-scale operations. Buck 'e pumps answer well for small hon = orchards where but 8 few trees are
 be sprayed. Where the orchard i D. terest is larger, and especially whe '.' older trees are to be treated, barr s- pump is essential. A barrel pun ;- may be purchased for 20 to 25 ds "a lars depending on the equipment
 spraying the outfit can be mount
 upon sled or placed in a cart or iwo "a on. An outfit for operations on "a still larger scale consists of 100 "a 200 gallon tank mounted upon tru "a having a strong .double-acting han n pump mounted upon it. For lar
 commercial operations. gasoline pow ,e outfits are largely used.
