Tobacco dust 1 lb. of 70-90 mesh containing- 1.97 percent nicotine 
sifted over the crown of a rasp"berr7 plant and the surrounding soil fol- 
lowed "by an application of 1 gal. water killed the advanced stage larvae 
without injuring the plant. The addition of water after applying tobacco 
dust greatly increases its efficiency and the use of 50 percent tobacco 
dust with 49 percent hydrated lime and 1 percent sodium carbonate greatly 
increases the rate of evolution of gas provided the mixture is moistened 
after application.

Sprcving with lime-sulphur mixture (2.5 percent), lead arsenate 
(l percent), or calcium arsenate (0.4 percent) before and after blossom- 
ing of the trees gave good results against the winter moth ( Che im at obi a 
brumata ) in contrast to different nicotine contact sprays.
