BETTER FRUIT 



June 



known as the 6-6-50 fornlula. 

 It should be used only upon 

 dormant trees. 



When the trees are in leaf 

 the following 4-4-50 formula 

 is used: Copper sulphate, four 

 pounds; quick lime, four 

 pounds; water, fifty gallons. 



A weaker formula, known 

 as the 3-6-50 formula, is some- 

 times used on plants of ten- 

 der foliage. In Oregon the 

 formula has been successfully 

 used on the peach foliage for 

 prevention of fruit spot, but 

 it is without doubt safer to 

 use the self-boiled lime-sul- 

 phur: Copper sulphate, three 

 pounds; quick lime, six 

 pounds; water, fifty gallons. 

 It is of great importance that 

 bordeaux be properly made. 

 The mixture must be fresh 

 each time it is used. The 

 ingredients may, however, be 

 stored in stock solution for an indefinite 

 period. Always use wooden or earthen 

 vessels in preparing bordeaux or the 

 solution of bluestone. 



When large quantities of bordeaux 

 mixture are required it is most con- 

 venient to have stock solutions made up 

 containing one pound per gallon of the 

 respective ingredients. Take a fifty-gal- 

 lon barrel of water and suspend near the 

 top a coarse sack containing fifty pounds 

 of crystallized or granulated commercial 

 copper sulphate. It will dissolve in a 

 few hours. It is convenient to arrange

this the night before the spraying is to 

 be done. In another barrel place fifty 

 pounds of lime freshly slaked. For this 

 purpose choose clean stone lime of the 

 best quality. Slaking should be done 

 carefully. Water should be added a little 

 at a time so that slaking will take place 

 rapidly. The process should be watched 

 carefully and the mixture stirred con- 

 stantly while the slaking is going on, 

 adding water as needed to prevent burn- 

 ing, as lime should never be allowed to 

 become dry while slaking or it will burn, 

 nor should it become entirely submerged

with water. The mixing can be con- 

 veniently done with a hoe. When thor- 

 oughly slaked make up to fifty gallons 

 with water. 



If small quantities only of stock solu- 

 tion are needed any quantity can be made 

 in the above mentioned proportions. 

 If the spray is to be applied to peach 

 trees in foliage use the 3-6-50 formula. 

 It is always best to test the mix- 

 ture before applying it with potassium 

 ferrocynide. 



These stock solutions can be kept for 

 an indefinite time if water is added to 

 replace that lost by evapora- 

 tion. They should be kept 

 covered to prevent dilution 

 by rains. Made up in this 

 way, each gallon of stock 

 solution represents one pound 

 of ingredients. Each should 

 be stirred very thoroughly 

 before any is taken out. 



In making up the mixture 

 from these stock solutions 

 both the copper sulphate and 

 the lime should be diluted 

 before being mixed. Have 

 two dilution barrels or tanks. 

 If the 6-6-50 formula be used, 

 and the spray tank holds one 

 hundred gallons, take twelve 

 gallons of copper sulphate 

 stock solution and dilute to 

 make fifty gallons in one bar- 

 rel, and take twelve gallons 

 of the lime paste and dilute 

 in the same manner in the 

 other barrel. The lime paste 

 should be run through a fine 

 strainer. 



For convenience it is well 

 to have a platform built high 

 enough to permit the liquids 

 to flow from the dilution 

 tanks into the spray tank. 

 Allow the two diluted solu- 

 tions to run together through 

 a twenty-mesh copper wire 

 strainer into the spray tank, 

 mix well and apply at once. 

 (It is always best to test the
