This is an important im-portant spray against the second brood of the codling moth and lesser apple worm; also the plum curculio, apple blotch and other insect pests and diseases. dis-eases. Later sprays may be necessary, but under average conditions the work as outlined above, if thoroughly done, should control not only the codling moth but the other more important insect in-sect pests and diseases of the orchard. Other spray schedules might be suggested, sug-gested, but this is the one which has given the best results in the tests of the Missouri agricultural experiment station. (By T. J. TALBERT, Missouri College of Agriculture.) Spray the apple trees immediately after the blossoms or petals fall in order to fill each little calyx cup or cavity with poison. About three-fourths three-fourths of the codling moth worms which hatch from eggs three or four weeks later enter the apples through this cavity. If we succeed in putting a few grains of arsenic in each little calyx cup the first meal the apple worm takes will be its last one. Since the calyx cups stand wide open for only a week or ten days, the spray must be applied within this time in order to be effective. What to Use. Commercial lime sulphur at the rate of 1 gallons to 50 gallons of water, and arsenate of lead paste at the rate of 2 or 2 pounds to each 50 gallons of spray mixture should be used. The trees should not be sprayed while in full bloom. Such work would Interfere with pollination, without which fruit cannot set, and destroy the fruit grower's best friend, the honey bee. It is safe to spray when two-thirds two-thirds of the petals have fallen, because be-cause the flow of nectar has practically stopped and few, If any, bees will be injured. This should be the most thorough and drenching spray of the season. A nozzle throwing a rather coarse driv- Light Power Spray Should Be Used on Orchards of Five Acres or More. ing spray with high pressure should be used in order te force the poison down deep into the calyx cups. Most Important Spray. This Is the most important single spray of the season. It not only controls con-trols the first brood larvae of the codling cod-ling mcth. but it also prevents, to a great extent, the losses occasioned by the later broods of the best. It is also an important spray in controlling the lesser apple worm, plum curculio, cankerworm, apple scab, black rot and other less important insect pests and fungous diseases. Later Sprays Necessary. The next spray should be applied about two or three weeks after the calyx spray. This will be about the time the majority of the first brood codling moth eggs are hatching, and if the surface of the leaves and fruit is thickly peppered with the poisonous poison-ous spray many of the worms will be killed by feeding slightly before they reach the blossom end of the little apple. ap-ple. Since this is also the first important impor-tant spray against apple blotch, bordeaux bor-deaux mixture should be used with the arsenate of lead if this disease is prevalent in the orchard. About eight or nine weeks after the blossom or calyx spray the third application ap-plication should be made, usinz the |
