2. The following known as the 6-4-50 formula is in very 



general use : 



6 pounds copper sulphate. 



4 pounds lime. 

 50 gallons water. 



3. BORDEAUX MIXTURE FOR PEACH FOLIAGE. 



The Bordeaux Mixture as ordinarily applied frequently injures to 

 some extent the foliage of the peach etc. causing a shot-hole effect 

 on the leaves. This injurious effect has been shown to be largely 

 obviated by the use of the following : 



3 pounds copper sulphate. 

 6 pounds lime. 

 50 gallons water. 



This is known as the 3-6-50 formula. Some experimenters have 

 also recommended the following for peach foliage : 



(a). 2-2-50 formula, (Cornell Agr. Exp. Sta. Bull. 180). 



(b). 3-9-50 formula. 



The latter contains three times as much lime as copper sulphate. 



4. BORDEAUX RESIN MIXTURE. 



5 pounds resin. 



I pound potash lime. 

 I pint fish oil. 

 5 gallons water. 



To make resin solution place resin and oil in a kettle and heat 

 until resin is dissolved. Cool slightly and then add lye slowly and 

 stir. Again place the kettle over the fire, add the required amount 

 of water, and allow the whole to boil until it will mix with cold 

 water forming an amber-colored solution. Take 2 gallons of the 

 resin solution and add to it 10 gallons of water. Mix this with 40 

 gallons of Bordeaux Mixture. 



Recommended for Asparagus Rust on account of its adhesive 

 properties. (N. Y. Agr. Exp. Sta. (Geneva) Bull. 188).
