Spraying With Bordeaux 



By Leroy Childs, Entomologist, Hood River 

 Experiment Station 



Apple tree anthracnose is causing 

 more damage in apple orchards of Ore- 

 gon than any other disease. In order 

 to effectively combat this disease, grow- 

 ers must be more vigilant than they 

 have been in the past. The Bordeaux 

 spray should be applied to every orch- 

 ard, and to be effective it must go on 

 as soon as possible. Every grower 

 should arrange his work so that the 

 spray machine will follow up the pick- 

 ing as fast as the fruit is removed. 

 Don't plan to do this, but do it. Early 

 rains may have caused infection to take 

 place, but this is only a fraction of what 

 will follow if the spray is not applied. 

 The approved way of mixing Bordeaux 

 follows: 



Manufacture: Use wooden containers 

 for dissolving the bluestone formula: 

 Six pounds bluestone, '6 pounds lime 

 (stone of best grade), 50 gallons of 

 water. 



Stock solution: Take a 50-gallon bar- 

 rel of water and suspend near the top 

 of the water a grain sack containing 50 

 pounds of bluestone, it will dissolve in 

 about an hour. Take 50 gallons of quick 

 lime and slack carefully, constantly 

 stirring, adding water as needed to pre- 

 vent it from becoming dry and burning. 

 When thoroughly slackened add water 

 to make 50 gallons. These stock solu- 

 tions then contain 1 pound each of the 

 original material to 1 gallon of water. 



Method: We have been placing the 

 materials direct into the tank diluted 

 with water, but the following proced- 

 ure is believed to give a better mixture. 

 It is as follows: (Use the "1-pound to 

 the gallon stock solution" mentioned 

 above). 1. Take 6 gallons of the cop- 

 per sulphate solution and add 19 gal- 

 lons of water. 2. Stir up the stock so- 

 lution of the milk of lime and take 6 

 gallons and add 19 gallons of water. 

 Pour together slowly into another bar- 

 rel (it takes two men to do this in order 

 that the amounts may be kept in equal 

 proportions) and stir thoroughly. It 

 will be found more convenient to pre- 

 pare the two solutions on an elevated 

 platform and run them simultaneously 

 from the dilution tanks into the spray 

 tank. Pour the mixture into the spray 

 tank, start the agitator and fill with 

 water. These proportions may be 

 mixed in larger units, but remember 

 to keep the proportions the same. 



Use plenty of material while spray- 

 ing and be sure to cover the large limbs 

 thoroughly. Bordeaux shows up nicely 

 on the tree and it is very easy to note 

 whether the spraying is being done well 

 or not.

The results are not only indicated by the thrifty appear- 

 ance of the trees themselves but are shown every year by 

 their heavy yield of fruit. 



Tree planting with dynamite is successful because it — 

 thoroughly loosens and shatters the sub-soil 

 makes root-penetration easy 

 puts great stores of plant food in easy reach 

 destroys fungus and nematode 

 causes early maturity 

 cuts down tree losses 



and pays a heavy return on the investment through increased 

 yields.
