ties given an equal number of sprayings during the season were not 

 injured by the spra}'. 



A question : Is there any particular position that you noticed on 

 the apple where the bitter rot first attacked it? 



No, there is no particular point on an apples where bitter rot first 

 attacks it as far as I know. 



A member: I noticed in my orchard, for a year or two, that it 

 was the side of the apple that hung to the south that it first attacked. 



That is a fact, as you probably noticed the apples on the south 

 side of your trees were first attacked, and then, naturally, on the out- 

 side, or on the south side of the apple. 



A- member: Xearh^ always on the side hanging to the south. 



In all orchards in South Missouri last year the first injurv was 

 ■on the southwest side of the trees, and naturally it would be on the 

 south side of the individual apple, but as to any particular point where 

 the bitter rot first attacks it, there is none. The statement is made 

 sometimes, and I have seen it in print, that it is necessarv for an insect 

 to injure apples before bitter rot could take hold. That must be a 

 mistake, because this vear, and last vear more especially, from one to 

 twentA'-five and even forty of the bitter rot specks were on one 

 apple. 



A question : Is any one variety afifected worse than others ? 



Yes, sir : A\'illow T^vig was the worst, and Ben Davis, Little Red 

 Romanite and Huntsman are all subject to the disease. I do not think 

 it would pay to plant a \\"illow Twig tree in any orchard in South ]\Iis- 

 ■souri. 



Xow regarding a few preventive measures for Bitter Rot. As is 

 known the spores live over the winter in the mummied apples and on 

 the trash, etc., under the trees and between them. In our experiment 

 work at Mountain Grove we took out everything from under the trees, 

 every mummied apple and all trash of any kind, and scraped the ground 

 with rakes several times. Unquestionably there is a difference when 

 this is done and when it is not, in the amount of spores that attack 

 the fruit, whenever the season is right for it. 



This year, in studying the disease, we found that bitter rot at- 

 tacked the trees differently than it did last 3-ear. Last year it usually 

 made its first appearance on the southwest side, and often high up in 

 the tree. This year we found that it made its first appearance on the 

 fruit on limbs growing near the ground, and that it gradually spread to 

 the higher branches. This should teach us the value of cleaning out 

 all of the mummied apples and the trash from under the trees.
