INJURING THE FRUIT. 71 



Summary of Treatment. — Soon after the blos- 

 soms have fallen, spray the trees with Paris green in 

 water mixture — 3 ounces to 50 gallons — to destroy 

 the Codling Moth and Curculios. Repeat the appli- 

 cation ten days or two weeks later. If the Pear-tree 

 Slug appears in the latter part of June, spray again 

 then. In the case of danger from the bark-lice or 

 apple-tree borers, carry out treatment recommended 

 under the special heads. 



Some authors recommend that in case the Pear- 

 leaf Mite becomes injurious the trees be thoroughly 

 pruned in winter, removing and burning as many 

 of the buds in which the mites are concealed as pos- 

 sible without injuring the trees.
