PROTECTION FROM INJURY BY THE JAPANESE BEETLE / 



PLUMS 



The lime spray recommended for peaches is also effective in pro- 

 tecting plums. 



CHERRIES 



The cherry crop is usually harvested before the Japanese beetle 

 appears in sufficient numbers to cause damage to the foliage or fruit. 

 After the fruit is harvested, an application of 6 pounds of lead arsenate 

 and 4 pounds of flour in 100 gallons of water is recommended for the 

 protection of the foliage. When leaf spot or yellow leaf is present in 

 the orchard, 2% gallons of commercial lime-sulphur solution should 

 be added to the mixture. It may be necessary to repeat the applica- 

 tion 2 or 3 weeks later. 



GRAPES 



Bearing and nonbearing grapevines can be protected by spraying 

 thoroughly with 6 pounds of lead arsenate and 4 pounds of flour in 

 100 gallons of water, or with 32 pounds of hy drated lime in 100 gallons 

 of water. The Japanese beetle does not feed on the fruit. The 

 spray should be directed downward from above to avoid excessive 

 residue on the fruit at the time of harvest, but every leaf should be 

 covered. Where it is the practice to use 8-12-100 bordeaux mix- 

 ture 2 on the grapes about the latter part of June, lead arsenate without 

 the flour may be added. Additional applications of these sprays are 

 usually necessary to protect the new growth that develops after the 

 first application. 



SMALL FRUITS 



As there is no satisfactory procedure for removing the spray residue 

 from raspberries, blackberries, and blueberries without causing 

 damage to the fruit, the bushes should not be sprayed until after the 

 crop is harvested. The lead arsenate and flour mixture may then 

 be applied to protect the foliage. 



SHADE TREES AND ORNAMENTAL SHRUBS 



The foliage of shade trees and ornamental shrubs that are subject 

 to attack by the Japanese beetle can be protected by spraying with 

 6 pounds of acid lead arsenate and 4 pounds of wheat flour in 100 

 gallons of water, or with 6 pounds of acid lead arsenate and 1 }i pints 

 of light-pressed fish oil in 100 gallons of water. These sprays, how- 

 ever, will not protect from damage the unfolding blooms of flowering 

 plants. The spray residue adheres well to the foliage, but it may be 

 necessary to make a second application 2 or 3 weeks later. 



2 Copper sulphate, 8 pounds; hydrated lime, 12 pounds; water, 100 gallons.
