FRUIT SPRAY PROGRAM FOR 
MINNESOTA 
Complete instructions for the recommended pro- 
gram may be obtained from the Agricultural Exten- 
sion Division, University Farm, St. Paul 1, Minn. 
The following is a suggested condensed program for home 
growers, designed to provide a reasonable degree of protection 
using the minimum number of applications and_ materials, 
Commercial growers should follow the more detailed recom- 
mended program. ; 
Spraying should be done under as high pressure as possible, 
egulate the discs of the nozzles so that the spray will be in 
the form of a mist. Cover the tree thoroughly. Spray at the 
proper time as a delay of a few davs will greatly reduce the 
effectiveness. Do not spray when blossoms are in full bloem 
stage.
