Some New Hampshire farmers have told me they preferred to fight the canker-worm by the banding, rather than the spraying, method, because their other work kept them so busy during the spray- ing season. But, in general, the orchardist will find it profit- able to spray, because he can thus kill oft'not only the canker- worms and other leaf-eating insects, but the codling-moth as well, and if he so desires, he can in the same mixture fight the apple scab and other fungous diseases. The spraying method of fighting the canker-worms aims to cover the leaves with fine particles of poison so that the young worms will eat it and be killed. When an orchard is infest- ed by canker-worms it is very desirable to spray once before the blossoms open. The insects begin hatching early in the season ; if trees are not sprayed until af- ter the blossoms fall considerable d a m - age will be done be- fore the worms are killed. One spray- ing when the buds are in the condition represented in Fig. 5 will be of much service. Another should be given as soon as the blossoms fall ; and if the canker-worms are very numer- ous a third—a week or ten days after the second—will be de- sirable. The spraying maybe done either with Parisgreen, Scheele's green, or arsenate of lead. Paris green may be applied in a water spray at the rate of one pound to two hundred gallons.
