CONTROL OF THE JAPANESE BEETLE ON FRUIT AND SHADE TREES 11 



SMALL FRUITS 



On account of the objection to spray residue appearing on small 

 fruits such as the raspberry and blackberry, protective sprays can 

 not be applied until the fruit has been harvested. Recent experi- 

 ments with certain varieties that produce two crops annually have 

 shown that sprays can be applied as soon as the first crop has been 

 picked without any injury to the second crop resulting from spray 

 deposits. One application of lead oleate coated lead arsenate, 9 

 pounds to 100 gallons of water, after the crop has been harvested 

 prevents further injury to the foliage and developing fruits. 



RECOMMENDATIONS FOR CONTROL IN CITIES AND TOWNS 



SHADE TREES 



Certain shade trees (fig. 8) and ornamental plants which are 

 favorite food plants 

 of the beetle are 

 grown extensively in 

 the towns and cities 

 in the heavily in- 

 f e s t e d zone. The 

 protection of these 

 plants from injury 

 has presented a dif- 

 ficult problem because 

 few property owners 

 are equipped to apply 

 the sprays properly. 

 Power spraying out- 

 fits are necessary to 

 protect a tree over 

 10 feet in height. 

 Property owners usu- 

 ally have only a few 

 trees or ornamental 

 plants to protect and 

 are in no position to 

 afford equipment of 

 this nature. 



During recent years 

 such situations have 

 been met by commu- 

 nities undertaking or 

 sponsoring a shade- 

 tree-spraying cam- 

 paign. Other com- 

 munities and indivi- 

 duals have employed commercial spray companies to do the work. 

 These arrangements have worked out quite satisfactorily. Details 

 regarding the organization of the community spray program can be 

 obtained from the local county agent. 



The following shade trees should be spra} T ed with lead oleate 

 coated lead arsenate. 9 pounds to 100 gallons of water, or, if small
