A spray of tobacco extract at 1 to 500 was ineffective against 
this moth ( Crambus caliginosellus Clem.). A spray of nicotine sulphate 
at 1 to 1,000 was not of much value in preventing injury by the worms, 
but seemed to repel flea beetles. Tobacco dust, scattered about to- 
bacco plants directly after planting, may possibly have some value as 
a repellent (p. 26).

Good results against Cra m bus haytiellus Zinek. attacking grasses 
were obtained from the use of tobacco dust applied with a dust gun. 
T/here lawns were thus treated the larvae were either killed or they mi- 
grated from the dusted area.

Nicotine sulphate (40-percent) solution gave little or no control 
against the larvae of moths of the genus Crambus (pyralidae).

Canes for planting in uninfected areas should be obtained free 
from borers ( Diatraea saccharalis crambidoides Grote) if possible other- 
wise they should be soaked for at least an hour in nicotine sulphate or 
bordeaux mixture, which prevents the eggs from hatching.
