Source of culture used. Apple variety. On Aug. 29. On Sept. 15. Years. Mm Ben Davis Arkansas canker Missouri Arkansas canker Yellow Newtown. The importance of cankers as sources of infection is also greatly ih creased by the enormous number of spores which a Single canker is capable of producing in a season. The writer estimated that the number of conidia in one canker 7 cm. Long by 2 cm. Wide, not a large specimen by any means, was not less than nine millions. When one considers that during moist hot weather the production of spores may be almost continuous, he realizes that the number produced from a single canker during one season must be enormous.

Download or read book Bitter Rot of Apples written by Thomas Jonathan Burrill and published by Forgotten Books. This book was released on 2018-02-15 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Bitter Rot of Apples: Botanical Investigations Department of Agriculture. Some direct, successful studies were made during the last quarter of the Nineteenth Century, and certain other important discoveries found afterward helpful had been made, but the knowledge which is at this date relied upon as a guide in the prevention of these losses has mainly resulted from investiga tions undertaken since the beginning of the year 1900. Thanks to these studies and experiments, it may now be said that what for merly seemed incomprehensible is easily understandable. The cause of the difficulty has been ascertained and a fungus identified as that cause. The time has gone by for any one to cavil in regard to the application of the word cause so used. It is true that the parasite must have conditions suited to itself, but conditions are not active agents. It is the fungus as the active agent working under permis sible conditions of susceptible fruits and of heat and moisture which must be charged, if there is to be such a charge, with the cause of the effects witnessed. Combative measures to be direct must be upon this basis, and even the control of conditions must be upon the assumption that this means warfare upon the living, injury-working parasite.

Book excerpt: Excerpt from Apple Blotch: A Serious Disease of Southern Orchards It appears, therefore, that apple blotch is the most destructive disease of the southern half of the apple belt. Occasionally bitter rot, as in the year 1900, overshadows all other diseases in destructive ness, but taken year by year apple blotch is more serious. Fortunately the disease Is amenable to treatment and can not gain a foothold In well sprayed orchards. It is not sporadic in its nature and must accumulate on the twigs several years before a serious outbreak on the fruit can occur.

Download or read book A Report on Plant Diseases of the State Classic Reprint written by John L. Sheldon and published by Forgotten Books. This book was released on 2018-02-20 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Report on Plant Diseases of the State Black Rot. This is another destructive disease, causing the fruit to rot and cankers on the branches. The young growth is some times killed, the twigs then resembling those attacked by the twig blight, for which it may be mistaken. The disease was found on apple leaves at Wellsburg. The black rot is similar to the bitter rot in general appearance, except that instead of the masses of pinkish spores that break through the Skin in the case of bitter rot, there are small black bodies imbedded under the skin in the case of'black rot. The shrunken and Shriveled apples often remain on the trees for a year or more. This disease has been Very destructive to quinces in several parts of the State. At a number of places where it was found on quinces, it was also found on apples near by. The same treatment is recommended as for bitter rot. It is possible that the black rot' might be controlled to some extent when it is found on quinces by picking the rotting fruit before the Spores have developed and become distributed. On apples this might not be feasible on account of the size of the trees. Canker. The cankers are the dead and shrunken areas occasionally found on the branches and trunk. They are due to a number of causes. (see under Bitter Rot and Black Rot.) One of the common ones found in old orchards is known as the Illinois Canker. It may be recognized by the black round bodies that push through the dead bark on the branches and trunk. These bodies are sometimes nearly one-fourth of an inch in diameter, and attached to the wood, so that when they are broken off, a black ring remains. Keeping the cankers and dead branches cut out should prove effective. Crown Gall. This has been reported as occurring on nursery stock shipped into the State. Several specimens of the disease have been received at the Experiment Station. It would be well to burn all infected stock, such as apple, pear, peach, cherry, raspberry and blackberry, that have hard, irregular, rough swellings on the crowns or roots, in order to prevent the introduction of the disease. The swellings or galls are sometimes covered with a large number of roots. A similar disease is produced by an insect called the woolly aphis.

Book excerpt: Excerpt from The Ripe Rot or Mummy Disease of Guavas It was not on account Of the economic importance of the ripe-rot or mummy disease of the guava that a study of the life history of the fungus causing it was begun, for at that time the disease was not thought to be of enough economic importance to warrant a careful investigation. It was studied, rather, as a side line along with the anthracnose of cucurbits, and more especially on account of its similarity to the bitter-rot disease of apples.
