unfolded, with the Copper Sulphate Solution, formula a, and again 

 just after the fruit was set, with dilute Bordeaux mixture, i. e., 100 

 gallons of water to the standard formula. Paris green was added, 

 1 lb. to 200 gallons, at this time to destroy the cureulio, but very few 

 of the peaches were attacked by them. At the time of the ripening 

 of the fruit of early varieties the trees were sprayed once with the 

 Ammoniacal Copper Carbonate reduced by adding water enough to 

 make 50 gallons of liquid with formula a. 



RESULT. 



The dilute Bordeaux mixture and Paris green did not injure the 

 foliage and may be considered safe to use on the peach, while the 

 dilute ammoniacal copper carbonate checked materially the rotting of 

 the fruit, though not wholly prevejiting it. 



TREATMENT RECOMMENDED FOR 1893. 



1. Spray trees before the leaves or flower buds unfold, with 

 Copper Sulphate, formula a. 



2. As soon as the petals have fallen, spray with dilute Bordeaux 

 mixture, i. e., 100 gallons of water to standard formula, adding 

 Paris green 1 lb. to 200 gallons of the mixture. 



3. When the fruit has reached two-thirds size, spray with dilute 

 Ammoniacal Copper Carbonate, i. e., 50 gallons of water to formula 

 a or b. 



4. Should no injury occur to the foliage, spray again in about 

 two weeks if rains have occurred, if not, no further spraying need be 

 done until it has rained. 



CONDITION OF PEACH BUDS MARCH 20, 1893. 



Another winter has passed and the buds are, thus far, much less 

 injured than for many years. The trees were examined every week 

 from December 1st to April 1st, and from 50 to 10(» buds of each 

 variety cut open at a time. 



\ The following table gives the average per cent of buds of each 

 variety that were destroyed March 20lh, 1893 : 



Reeves' Favorite, 



Wager, 



Wheatland, 



Crosby (Excelsior) , 



Stump,
