For red spider and plant mites use flowers of sulphur as a dry powder dusted over 

 the trees when covered with dew or immediately after a rain. 



For hibernating insects use a miscible or soluble oil at the rate of i part of oil to 

 12 or 15 parts of water.

Bordeaux mixture; 5 Ibs. copper sulphate and 5 Ibs. lime in 50 gal. water. 

 Ammoniacal copper carbonate; 6 oz. copper carbonate and 3 pts. ammonia in
