The addition of 40-percent nicotine sulphate (1: 800) to the 
last application of a lead arsenate and fish-oil spray resulted in a 
greater efficiency than without the nicotine. Nicotine sulphate should 
be included in the 10-day spray, since it is effective against the 
grape-berry moth polychrosis viteana Clem, and the grape leaf hopper 
( Erythroneura c omes Say. ) .
