The remarkably successful results of apple growers in the Rocky Mountain, Pacific and North- western States, in controlling codling moth are Based upon methods aimed at this insect alone, since the curculio is not destructive if at all present in those sections. Missouri fruit growers must, however, make allowance for an addi- tional and equally important factor—the curculio. There have been, upon the other hand, some very effective plans of sprays advised by entomologists, after experimental trials, to be used on apples with curculio principally in view. Since both insects have always to be dealt with in Missouri orchards it seemed that the problem was worthy of further study in perfecting sprays serving both purposes. The orchard spraying problem in Mis- souri, like many of the Mississippi \''al- ley States, is further complicated by the prevalence of several serious fungus dis- eases, most prominent of these being apple scab and bitter-rot. In the experi- ments of the writer these were taken into consideration, and in so far as they have bearing upon the sprays for the two insects under discussion they will be briefly referred to Figure 9—PICKED APPLES FROM PLAT 5 No. I's, on left, 70 per cent; No. 2's, on right, 30 per cent.
