procedures recommended undoubtedly have reduced infestation, they 
have not afforded the trees adequate protection. Commercial peach 
growers for the most part have de- 
pended upon ‘‘worming’’ the trees. 
A few use a wash on the trunk after 
worming, or mound the earth around 
the trees, or do both, but the great 
majority have followed no other 
method than worming the trees in 
the fall or spring, the more careful 
growers worming during both seasons. 
Worming of peach trees has always 
been a bugbear to the commercial 
orchardist. It is a disagreeable and 
arduous task and likely to be slighted 
by the worker. Unless done consci- 
entiously and thoroughly, with due 
care to remove all borers and not to 
injure the trees, worming is of ques- 
tionable expediency. A _ decidedly

better method of borer control, 
especially valuable for commercial 
growers, has been developed by 
the Bureau of Entomology and is 
described on pages 10-14. Careful 
worming of trees, however, may 
be preferred by some, especially 
where only a few trees are involved, 
as in small home orchards. 
‘““WORMING.”’ 
Previous to worming, the earth 
should be removed from around the 
crown of the tree to a depth of 4 or 
5 inches, and, if feasible, the trunk 
brushed or scraped to remove loose bark and dirt. With a little 
experience the worker can readily locate the borers in their burrows
