eventually the spot is a more or less irreguiar blotch with a sharply defined gray 

 center surrounded by concentric brown rings with lighter zones betvreen. 



Badly infected leaves turn yellow, drop prematurely, reduce the vitality 

 of the tree and affect fruit production the following year. 



Control ; 



1«, Prune out all dead or cankered wood and destroy mummies before nevf 

 growth starts in spring to reduce amount of infective material, 



2. Protect leaves and fruit with ferbam, captsin, or Crag before rains, 

 A good scab control program early in the season will protect the leaves and fungi- 

 cides in the summer insect sprays will protect the fruit.

COLD STORAGE HINTS

Keep the Relative Humidity High. Up to the present tlratb the main apple 



producing areas of the State have received no appreciable amount of rain since early 



August, Any used boxes or crates to be used as orchard storage containers are bone 



dry and unless we get some heavy rains will remain so when they enter the storage. 



Since a dry box may absorb up to a pound of tirater, one should be sure to soak the 



boxes well before they enter the storage or as soon as they are placed in storage. 



One can soak them regardless of whether apples are in- the containers or not. Don't 



forget to use your humidity instruments and add water to the room when needed, A 



relative humidity of 90 to 9S% is what you want. Once apples have lost about ^% cf 



their weight as water they will show some shriveling. 



Cool the Apples Rapidly to 32 degrees F, Move apples to the storage 

 as rapidly as possible. Every day an apple remains at 70 degrees F, about one weel 

 cf storage life is lost, Mcintosh apples held at iiO degrees F, for the first month 

 in storage may not keep a month or six weeks as long as similar apples held contin- 

 uously at 32 degrees F, 



Failure to cool apples rapidly to 32 degrees F. probably constitutes 

 one of the main reasons why many Mcintosh are not in a firm condition by January or 

 February , 



I- Pick Apples Before They Become Too Soft , Sometimes apples do not keep 



well because they were too ripe when picked. The use of a pressure tester can 

 serve as a guide in determining when Mcintosh apples are becoming too soft for late 

 storage. For good storage I.'lclntosh should be picked before the flesh is softer 

 than lUtO pounds using a 7/16 inch headT Most of your county agents have a pres sure 

 tester which is available for your convenience. Make use of it or obtain one of
