RECO MMEND ATIONS. 



In order to control apple scab and codling-moth in the apple orchards 

 of eastern Nebraska, spray the trees as follows: 



(1) Spray with Bordeaux mixture after the cluster buds open, but 

 before the individual flower buds open. 



(2) Spray with Bordeaux and some poison, such as arsenate of lead, 

 Paris green, etc., as soon as possible after the blossoms fall, and at any 

 rate before the calyx lobes of the apple close. 



(3) Spray with Bordeaux and poison three or four weeks after the 

 flowers fall. 



(4) Spray with arsenate of lead about July 20th. 



(5) Spray with arsenate of lead about August 10th. 



Use Paris green at the rate of one-fourth to one-third pound per 

 barrel of Bordeaux. Use arsenate of lead at the rate of two pounds 

 per barrel of Bordeaux or water. 

 Make Bordeaux as follows: 



Bluestone 4 poxmds 



Quicklime 6 pounds 



Water 50 gallons 



Slake the lime, dissolve the bluestone, dilute each with half the required 

 quantity of water, and mix thoroughly. 



Use good nozzles and maintain a high pressure as uniformly as 

 possible in order to distribute the liquid in a mist-like spray. Take 

 care to reach all parts of the trees and to avoid drenching any part. 

 Careless spraying should not be tolerated.* 



* For a detailed discussion of methods of preparing and applying 

 Bordeaux mixture see Farmers' Bulletin No. 247 of the U. S. Department 

 of Agriculture, entitled "The Control of the Codling Moth and Apple 

 Scab."
