4() DECIDUOUS FRUIT INSECTS AND INSECTICIDES. 



it is obvious that anything Avhich will tend to mitigate or prevent 

 these conditions will in tnrn largely prevent the borer's presence. 

 Therefore proper orchard management, keeping the individual trees 

 in a good, clean, and vigorous condition of health, avoidance of 

 mechanical injury when cultivating, and prompt treatment of wounds 

 made about the body of the tree, are the surest ways to keep the 

 orchard free from this insect. 



For its control in orchards already infested there is but one avail- 

 able remedy, namely, cutting the worms or larvae out of their bur- 

 rows. This is best done in conjunction with the regular " worming "' 

 for the peach borer, the operator taking care to examine all portions 

 of the trees from the roots up to the large limbs above the fork. In 

 doing this it will be necessary to cut away portions of the bark, and 

 wounds so made should be promptly cleaned and treated with some 

 protective antiseptic, as thick Bordeaux mixture or the lime-sulphur 

 wash. All rough, cracked, or diseased areas should be cleaned out 

 and similarly treated, whether they are infested or not, as they form 

 points of entrance for the borers and are in other ways a menace to 

 the life of the tree. The " worming " for this insect should be ar- 

 ranged for the early spring, if convenient, as wounds made at that 

 time heal more readily, and, besides, the larvffi are then pupating in 

 numbers and can be more easily gotten at. 



So far as known, other remedial treatments in the shape of caustic 

 or preventive washes are practically worthless in the control of the 

 insect, and their application would be merely a waste of money.
