Excerpt from Apple Rots in Illinois
Fruit burn. As indicated by the name this is a scalding of apples due to the sun's heat. Ordinarily this trouble is confined to the fruit after it has fallen to the ground, though during the past unfavorable apple season there has been some complaint of the fruit burning on the trees; The apples as they lie on the ground begin to scorch on the south or sunny side and the brown discoloration gradually increases in size both by spreading over the surface and by extending inward, eventually forming a sort of baked apple. In its earlier stage diseased tissue taken from the interior of such apples for cultural examination gives no growth of bacteria or fungi, but in time, no doubt, these agents often aid in the destruction of the tissues. The trouble, apparently, is not a very serious one. Plate A, Fig. 1, shows an apple affected with fruit burn in its earlier stage.

Paperback. Condizione: New. Print on Demand. This book details our present understanding of the different fungi that cause apple rot, a significant issue for fruit growers, particularly in the southern half of the state of Illinois. The author's work through the years 1879-1902, brought together here, describes various species of fungi that cause different types of rot. The author notes that while there are numerous fungi that can cause apple rot, the most aggressive and destructive is the bitter rot fungus, which has been known to ruin entire harvests, laying waste to entire orchards. The book contains detailed descriptions of the physical manifestations of infection by the various fungi, allowing the reader to identify them by the patterns and appearances of the rot. Further, the text includes the author's experiments in both preventing and inducing apple rot, and discusses the various methods of infection and the ideal conditions for the spread of rot. Many of the fungi that cause apple rot have been studied by other researchers, and the book also includes a review of that research, thus providing a comprehensive record of our understanding of apple rot up to 1902. This book is an essential resource for anyone interested in the cultivation of apples, particularly in the southern half of Illinois, or anyone with a general interest in plant pathology and mycology.
