Even so and for all that, man protects his tree by spraying it with poison, and thereby again does he have dominion. The spraying for apple-scab is with lime-sulfur to which may be added arsenate of lead. This treatment, properly timed, may suffice also for the codlin-moth.
The feature spots are now still more prominent on these apples, the ribs more pronounced, the blush against the sun more warm. Both these fruits, from one spur, will mature; but the smaller one will be blemished, for the apple-scab fungus has established itself on the crown and about the calyx. Already the growth is checked in that area, and the apple looks flattened.
On the leaves are spots or lesions, injured or "diseased" infected with the apple-scab fungus. Under a good microscope the investigator finds immature fruiting bodies in these areas. In the early days of Spring, these bodies or winter-spores mature. A rain discharges them in astonishing numbers. The tissue is penetrated and killed so rapidly that the practiced eye soon discovers a "spot."
