These studies deal with the moth, called the western peach and 
prune root "borer. The soil was removed from the "bases of fruit trees 
and 40-percent nicotine sulphate, nicotine oleate, nicotine resinate, 
or tobacco dust were applied aid the top soil was replaced. In no case 
was there a satisfactory control, and these substances do not seem 
promising (p. 331). Nicotine sulphate was also used in tree -rashes 
containing 5 or 6 different substances, and it may have had some value 
(pp. 333, 335) .

■Whitewash treatments have been found beneficial, a successful 
formula being 8 lb. quicklime, 1/4 lb. lead arsenate powder, 2 lb. salt 
1/4 lb. glue, 2 oz. 40-percent nicotine sulphate, and enough water to 
make into a thick paint.

A spray consisting of 2 lb. soluble sulphur, .l.pt. nicotine sul- 
phate, 4 lb. fish-oil soap, and 100 gal. water, applied as a drenching 
spray immediately be-fore the blossoms opened, gave almost perfect contrc 
of budmoths, canker-worms, fruitworms, and many other lepidopterous 
larvae.

Nicotine (1:400 or 1:800) was the only insecticide effective in a 
apple orchard heavily infested with budmoths particularly the eye-spotte 
budmoth ( Eucosma ocellana Schiff.). The use of a spreader did not in- 
crease its effectiveness.
