A 2 percent nicotine solution gave good results in some localities. 
A 2 percent tobacco extract gave good results against the second genera- 
tion, "but the most effective remedy against the larvae of the first 
generation is lead arsenate. Though tobacco extract is recommended, it 
is at present very costly and its nicotine content is variable. Its use 
may result in scorching.

Spraying in spring with lead arsenate is recommended for the 
control of Clysia ambiguella and P olychrosis botrana. In summer 
nicotine is used. The formula recommended is ordinary bordeaux 
mixture 20' gal . , titrated extract of nicotine 1 l/8 pt . , ordinary 
soap, 4 lb. Barium chloride may be used instead of the nicotine.

Vines were sprayed with a solution of 2 percent tobacco extract 
and 0.2 percent soft potash soap. The reduction in the number of 
larvae ranged from 71 to 85 percent. Other insecticides were also 
used, but it was concluded that the vine moth control was not en- 
tirely solved.

For the control of the vine moths Polychrosis botrana and Clysia 
gmbiguella two treatments are used, namely, two sprayings in spring with 
arsenicals and a siimmer treatment with nicotine. Summer treatment be- 
gins as soon as the grapes begin to develop; for this nicotine should 
be mixed with a copper solution.
