 p. 368, c. 2 — 15 cm.) 



In answer to inquiries from Brockport, N. Y.: Spray for the canker-worm 

 with Paris green when the apple-tree buds are opening, again before blossom- 

 ing. For the codling-moth, after the blossoms have fallen, and again a week 

 or ten days later. For preventive of apple scab, spray with a solution of 

 copper sulphate before growth starts, or with ammoniacal solution of copper 

 carbonate. For pear-tree blight, spray with the last-named solution as the 

 leaves begin to open, and repeat two or three times at intervals of two 

 weeks. For quince-tree blight, same as preceding. A formula is given for 

 an insecticide and fungicide combined,

Apple-Tree Borer. (Country Gentleman, for May 18, 1893, Iviii, 

 p, 387, c, 1 — 17 cm.) 



Two pupae sent from Fairlee, Md., found in the trunk of an apple-tree are 

 those of the apple-tree borer, Saperda Candida Fabr. Chrysobothris femor- 

 ata (Fabr.) — also an apple-tree borer, is referred to. Probing the Saperda 

 burrow with a wire is the remedy usually employed. A newspaper 

 arranged according to directions given, around the base of the tree, is 

 claimed to be an effectual preventive. 



The Bud- Worm. (Country Gentleman, for May 18, 1893, Iviii, 

 p. 387, c, 1 — 14 cm.) 



The best remedy known for the bud-moth [Tiiietocera ocellana] is spraying 

 with Paris green just as the buds begin to open. Paris green may be used 

 in a stronger solution without injuring the opening buds, if combined with 

 Bordeaux mixture, than if used alone. Bordeaux mixture would also ward 

 off the very prevalent apple-scab .
