SPRAYING NOTES ON THE CONTROL OF THE FRUIT TREE LEAF-ROLLER IN THE HOOD RIVER VALLEY
In the face of the already valuable information that is available on the life-history and the control of the leaf-roller, this paper and the work that it represents might appear to some as superfluous. In citing the literature, however, I find little or no published experimental work dealing with the control of this serious and numerically increasing apple pest on the Pacific Coast. A still more important point which made experimentation, at least with the oils, imperative was to determine if possible what influence spring applications of oils have on the adhesive properties of fall applications of Bordeaux mixture. In the Northwest we have a very serious apple disease known as apple tree anthracnose, for control of which Bordeaux is applied before the early rains in the fall. It has been suggested, and seems, indeed, quite possible, that there may exist some such condition, information relative to which is desired before the general use of oil can be recommended. The anthracnose spray has not been applied with the result that a report on this point is impossible at this time. The leaf-roller, however, has passed through its period of activity for this season and the data gathered relative to its control is complete.
