Our experimental work on bud-moth control in Nova Scotia was coiimipnccd iii the orchard of Mr. R. S. Eaton of Kentrille, , in 1912. A ten acre orchard ol Wa«ner applet, planted 8 feet 2 inches each way was selected. This was divided into 12 plots, three of which were used as checks, the remainder being sprayed at different dates to the sprays which were most effective. A combined spray of lead arsenate, 5 pounds to KK) imperial gallons, and lime sulphur 1 to 40 was used, the â pray being applied with a hand pump. At that time it was open question as to whether the spray applied when the buds were opening and showing green at the tips, was the best spray in bud-moth control. The experiment was carried on for two years. The following table gives the results obtained:â. Fig. 9.âBud» from Ribston apple tree, 100 per cent infested by larvie of the Ey»potted bud-moth, and the blosMima borne on a mmilar twig fnnn the «ame tree. (Original.) Spray A. in table No. 1 means the one applied just when the tips of the buds wi-re showing green. Spray B. about three days before the blossoms. Spray C. immediately after the blossoms, and spray D. two weeks later than spray C. These results shown in Table No. 1 indicate that while thorough spraying as in plot No. 4 was preventing the increase of the insects in an infestation which was rapidly becoming more intense, there was still plerty of room for improvement in methods of controlling bud-motha. The hand outfit with low pressure was not givinjf the results that many growers wore getting with power outfits. The life-history of the bud-moths was studied at this time, and it was found that a period of 10 days elapsed in 1912, and 11 days in 1913, between the time the first larva left its winter quarters to b
