132 THE AMERICAN PEACH ORCHARD 



verted position upon a wheelbarrow or some sim- 

 ilar truck so as to have the open slit at the forward 

 end of the circular catcher. This big canvas is then 

 run under each tree and the tree jarred so as to 

 cause the beetles to fall into it. The beetles are then 

 easily collected and burned. In some cases this 

 method doubtless pays its way. The energetic fruit 

 grower must be his own judge as to whether he 

 can afford this expense of jarring the entire orchard 

 five to 15 times during the growth of the crop. 



Really the most practical method of meeting the 

 attacks of the curculio is by spraying with arsenical

poisons. White arsenic, paris green or arsenate of 

 lead may be applied in the usual manner with the 

 spray pumps. Two or three treatments are required. 

 The first should be given very soon after the blos- 

 soms fall, the second treatment two weeks later, 

 and the third treatment, if one is given, two weeks 

 after the second. As paris green 'is apt to injure 

 peach foliage it is not recommended, though careful 

 applications, especially in combination with lime or 

 well-made Bordeaux mixture, may do no harm. 

 Arsenate of lead is by all odds the safest and best 

 of the arsenical poisons, and is now generally super- 

 seding all others in orchard treatment.
