To No. 1 was applied the ammouiacal carbonate of copper mix- 

 ture, as given in the previous (bruuihi, with 1 part of Paris green to 

 200 of the mixture. 



To No. 2 was applied the same copper solution and 1 lb. of Paris 

 green to 300 parts of the mixture. 



No. 3. Check tree. 



To No. 4 was applied the ammoniacal carbonate of copper solu- 

 tion and 1 lb. of Paris green to 400 gals, of the mixture. 



No. 5. Check tree. 



To No. 6 was applied a mixture composed of one ounce of carbon- 

 ate of copper, 4 lbs. of quick lime and 22 gallons of water. With 

 this mixture Paris green was used in the proportion of 1 lb. to 500 

 gallons. 



To No. 7 was applied simply the ammoniacal carbonate of copper 

 solution without any Paris green. 



The above trees were sprayed May 29th, June 7th, June 17th, 

 July 1st and July 31st. The last time no Paris green was used. 

 The results are shown by the following table. 



*Check trees. 



RESULTS. 



Again the same results with the Paris green are obtained, as in the 

 first experiment, reducing the injury from the codling moth to 29J%, 

 while where no Paris green was used the per cent of wormy fruit 

 was 70. 



No beneficial results were obtained from the use of carbonate of 

 copper or Bordeaux mixture. In fact, in every case the amount of 

 scab is larger where the fungicides were used than where not used. 



This result may be in part due to the injury resulting from the 

 Paris green, which was especially noticeable where it was used at 

 the rate of 1 lb. to 200 and 300 gallons of the liquid.
