Show PAYS TO SPRAY APPLE TREES Comparatively Few Orchardists Who Doubt Advisability of Spraying for Injurious Insects. There are comparatively few orchardists or-chardists at the present day who doubt the value of spraying apples for the curculio and the coddling moth. On the other hand there are many who are, in reality, not protecting their orchards from these two cardinal cardi-nal apple pests as is possible, or, indeed, in-deed, practicable. Undoubtedly the worst enemy of the apple crop Is the coddling moth the insect that causes the wormy apple. This pest is taking altogether too much toll from the apple ap-ple growers and as the fruit industry Cash Value of Crop Doubled by Sprays. On the Right 80 Per Cent, of Number One Apples.

It is unnecessary to go into detail in explaining all the reasons why fruil wormy from the coddling moth or stung and deformed by the curculio. is permitted. Suffice to say in many cases there is no reasonable excuse, except the failure of persons to carry out plans of spraying which are already al-ready known to be effective. There is' a strong tendency, however, how-ever, among fruit growers in genera) to do more careful, and intelligent spraying so that a higher per cent, of first-class fruit may be produced.

Since the curculio and coddling moth are probably responsible for over 90 per cent, of all blemished and windfall apples caused by insects against which sprays are used, the subject is one deserving careful study by every successful apple grower. In controlling the above-mentioned as well as other insects, apple growers grow-ers should apply their arsenical sprays at times when they will be of the greatest possible service. There Is a limit to the number of sprays which can be profitably applied, especially since in many cases it Is also necessary neces-sary to give separate sprayings of fungicides at times when no insecticide insecti-cide Is required and vise versa. For instance, it is generally conceded that spraying with a ' fungicide is necessary neces-sary before the opening of the apple bloom, for the purpose of reducing apple scab, though the addition of an arsenical at that time can have no effect in destroying the larvae of the coddling moth and little, if any, value against the curculio. Again, sprays of Bordeaux mixture, when used late in the season at the time of the appearance appear-ance of bitter-rot are given at a time too late to be of much value in preventing pre-venting damage from either of these two insects. A very important spraying Is the one Just as the blossoms begin to show the pink. At that time we get the two kinds of canker worms, bud moth, leaf roller, aphis and curculio. But the most Important spraying is :he one for the coddling moth, just ifter the petals fall and after the bees lave stopped working on the blossoms at that spraying we try to get poison into the calyx of every apple.

Moreover, with poison on the leaves some worms never live to reach the calyx. ; The second spraying for coddling worms is about 10 to 14 days after the first, and is to cover any blossoms blos-soms or leaves that were missed at the first spraying. Both of these sprayings are made as thoroughly a possible |
