In spraying for the Codling Moth oiir object must be to see that every calyx end of the forming fruit is covered with the poison before the calyx closes. The deeper the poison is driven into the cavity at this part the more certain will be the destruction of tuc larvae trying to enter here. Therefore to accomplish this it is necessary to do very thorough work and to have as high pressure as can be conveniently obtained, never less than loo lbs. and if possible as high as 150 or even 200 lbs. Endeavor to hold the nozzles about 20 inches or 2 feet away from the blossoms and to send the spray directly into each. Anyone who tries to do this on a tree that has been well covered with bloom will soon sec that it requires great care, and before it is accomplished the tree will have been drenched. It is easy to see therefore that the old rule to stop spray-. Fig. 19. Tower for spraying UU trees, and spray tank with gasoline engine. ing when the mixture begins to drip is quite wrong. The rule should be: Stay at the tree till you have put the poison thoroughly into every calyx but waste no more material than you can help. From time to time examine the calyces to see if any are being missed. Do the soraying yourself or trust only your bsst man to do it. A careless man t spray well. Large trees may sometimes, if e have been many blossoms, r^uire as high as from 8 to even 15 gallons, and 's of 25 or 30 years of age from 4 to 8 gallons. If the tree has onl^ ^ very few blossoms look after these carefully and give the foliage a light coat to keep it hralthy. If time is pressing the trees that have had no bloom may be left until all the others are done and then touched Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability
