Nicotine sprays have proved excellent in Luxemburg against the 
second generation of the vine moths Clysia ambiguella Kb. and Poly- 
chrosis botrana Schiff . The minimum effective strength of pure nicotine 
is 1#5 per mille. ^he nicotine can be used with bordeaux mixture but 
is better in water containing 1/2 percent soft soap.

The spray used in Austria and Germany with satisfactory results 
against the vine moths ( Pplychrosis botrana Schiff. and Cly sia am- 
biguella Hb. ) consists of bordeaux mixture containing 0.15 or 0.20 
percent paris green, 0.75 or 1.00 percent quicklime and 2.5 percent 
tobacco extract.

The substitution of lead arsenate for nicotine against the second 
generation of Clysia ambiguella Hb. and pplychrosis botran a Schiff. is 
recommended, since not only is it as effective and. less expensive, but 
it has been found that nicotine is more likely to affect the quality of 
the wine .

Wines made from grapes which had been treated throughout the 1929 
season with nicotine, copper, and arsenic sprays were examined for 
quality (taste) and for the presence of nicotine. Nicotine was not 
found in sufficient quantity to be injurious to health, but there was 
sufficient to seriously affect the taste, especially with wines from 
grapes sprayed late in the season. Most of the nicotine was found in 
the lees. The nicotine content was appreciably greater than in either 
1927 or 1928 wines from the same district.
