Book Description
Excerpt from The Control of Apple Blotch, Vol. 15: 1919-20 Apple blotch has become one of the most destructive apple diseases in many orchards of southern and more particularly of southwestern Ohio. It is spreading rapidly northward and eastward. Already it has become a problem of state-wide magnitude to apple growers. This publication is designed to give practical information on apple blotch and its control, based on the results of demonstrations conducted jointly by the Agricultural College Extension Service of the Ohio State University, cooperating with county agricultural agents and apple growers. The Fungus. - Apple blotch is a fungus growing on the fruit, foliage, and twigs of the apple. It is seldom a serious trouble on foliage, where it is evidenced by small grayish-white spots. On the fruit, twigs, and fruit spurs it becomes extremely serious on susceptible varieties. On the fruit, the disease first makes its appearance as a small brown spot which rapidly enlarges, showing a ragged border of radiating splashes. Severe infections are followed by a cracking open of the apple toward the end of the growing season. Apples badly infected in this manner become worthless for any purpose, even for cider stock, as the flesh of the apple dries up into a spongy mass. On the fruit spurs, terminal twig growths, and water sprouts the disease develops typical cankers. On extremely susceptible varieties, such as Duchess of Oldenburg, Northwestern Greening, and Mann, infected fruit spurs are often seriously weakened or killed outright by cankers. Badly cankered trees lose an immense amount of bearing surface in this manner and become very unproductive. Pathologists who have investigated the life history of the blotch fungus report that the disease holds over winter in these cankers. It is their conclusion that little, if any, spread of the disease from year to year occurs from mummied fruits and diseased foliage. A spray treatment which will prevent the formation of new cankers and gradually eliminate the old ones, at the same time keeping the apples and foliage free from infection, is the basis of Such a plan was attempted in the demonstration Twigs showing apple cankers. blotch success in blotch control. work, some of which is reported in this bulletin. These demonstrations were conducted during the seasons of 1918 and 1919 in Clermont, Hamilton, Warren, Scioto, and Washington counties.
