At any event tlie Vednlia did not control this insect and it was nec- essary to devise some means of arti- ficial control. .Spraying with oil emul- sions and using crude oil as higli as 35 to 40 gallons per 20U-gallon tank failed to control this insect, and the pears were sticky and smutty by pick- ing lime, due to the work. Experi- ments last year showed that a miscible oil, used about 12 gallons per 2(l(l-gallon tank in combination with several gal- lons of cresol soap (extra) to increase the welting power and penetration, controlled tliis insect admiiably and succeeded in killing most all of the eggs. In aildition to this the treatment stimulated the trees very materially, and they came out in bloom ten or fourteen days ahead of unsprayed trees, and set a much heavier crop. Laundry soap applications in combi- nation with home-made distillate-oil emulsion killed the scale cjuile readily, but the friiil buds also, and was al)an- doned by the owner of the orchard in favor of the miscible oil and cresol- soap combination. This condjination. or one such as miscible oil in combi- nation with liciuid whale-oil soap, could pr(il)al)ly lie adjusted and used to advantage in the Northwest for fall applications of the Woolly Aphis, and also for Scale insects where great wet- ting power and penetration is de- sirable without increasing the oil con- tent very malerially. In fact the oil content can be cut down below normal for these fall applications after the extra soap is added. Lime - sulphur solution and Black Leaf 40 have been used to advantage in the Northwest and elsewhere for scale, fungus and aphis. Wilson, in "Biennial Crop I'est and Horticulture Report" for 1913, reconunends coml)i- nation of lime sulphur 1-10, plus Hlack Leaf 40, 1-000, just after the fruit buds open to destroy the Aphis stem mothers. This also has the advantage of being a scalecide.
