ONE-SPRAY METHOD FOR CODLING MOTH, ETC, 135 
The demonstration plat (XIII) received in all three treatments of a 
combined Bordeaux mixture and arsenate of lead spray. Plat XV 
(one-spray method) received only one arsenate of lead treatment just 
after the falling of the petals, but two additional applications of 
Bordeaux mixture were given to protect the fruit and foliage from 
fungous diseases. Plat XVII was left unsprayed throughout. The 
Ben Davis variety of apple was used entirely in the experiments.
