When to Spray. (Country Gentleman, for May 11, 1893, lviii, 

 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. 



Clover-Leaf Weevil. (Country G-entleman, for May 18, 1893, 

 lviii, p. 386, c. 4 — 29 cm.) 



Clover fields in Hillsboro, Va., injured by the clover-leaf weevil, Phytono- 

 mus punctatus. Imported from Europe; when first noticed; distribution; 

 ravages arrested by fungus attack; indication of attack; habits, life-history 

 and figures in the Country Gentleman, for May 29, 1889, in the Annual 

 Report of the Department of Agriculture for 1881, and in the First Report 

 on the Insects of New York. Two remedies: Plowing the field before the 

 larvae have matured; crushing the larvae by going over the field after dark

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

 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, lviii, 

 p. 387, c. 1 — 14 cm.) 



The best remedy known for the bud-moth [Tmetocera 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.
