What should 

 sprav your trees 

 IX, 



tions and at 



the apple growers 

 with 3 lbs CaCl-7 



tl 



do in 1976? We suggest that you 

 er 100 gal as separate applica- 



beginning about"the 1st cover and repeated at 2 



to 3 week intervals, totalling 5 to 6 applications. Those who ap - 

 ply pesticides at IX may want to add the CaCl2 to one tankful in 

 each cover spray as a trial; we have seen no evidence of incompati- 

 bility but with the many possible combinations, caution is advised, 

 If foliar damage appears and is considered excessive , reduce the 

 CaCl_ concentration to 2 lbs per 100 gal in subsequent sprays.
