 Some of the Benefits from Spraying with Arsenates in the Apple 

 Orchards of Nova Scotia. — Canadian Entomologist, London, Onl., 

 xlvii, no. 5, May 1915, pp. 137-Ul. 



A six- to seven-year-old orchard in the AnnapoUs valley was sprayed 

 in order to determine the extent of benefit derived from each of the 

 four applications normally employed there. The spray used was 

 commercial lime and sulphur, one to thirty-five, and Swift's acid paste 

 lead arsenate, 5 lb. to 100 gals. Spraying reduced the number of 

 bud-moths {Eucosma ocellata) by 60-75 per cent, and fruit-worm 

 (Rhagoletis pomoncUa) injury by 65'19 per cent, in 1912. In 1913, with 

 a much lighter infestation throughout the orchard, the benefit was 

 63'56 per cent, reduction in fruit-worm injury. The codUng moth 

 {Cydia pomonella) infested 4-54 per cent, of the control apples in 1913. 

 It was found that the second application of spray gave 71-3 per cent, 

 reduction in injury, the third 65-6 per cent., and the fourth 65-6 per 

 cent. The first apphcation was made when the buds were bursting, 

 as soon as the first bud-moth started eating its way into the bud ; 

 the second was appUed from two to three days before the blossoms 

 opened ; the third immediately after the blossoms fell ; and the 

 fourth two weeks later. The results obtained were almost entirely 

 derived from the second and third sprayings, the additional benefit of 

 the fourth apphcation being so small as to be scarcely noticeable.
