Satisfactory results were attained in the control of Clysia 
ambiguella and Polychrosis botrana with ordinary bordeaux mixture 
to which from 1 1/2 to 2 percent of tobacco extract had been added. 
Spraying against the first generation was carried out between May 25 
and June 2 and against the second between the 16th and 20th July. In 
a vineyard at Ivrea 8.57 percent of treated grapes and 53.66 percent 
of untreated ones were injured, the other conditions being equal. At 
Palazzo the figures were 17.6 and 34.1 respectively in one vineyard, 
and 8 and 16 in another. Neither leaves nor grapes were scorched ex- 
cept in one instance where an overdose of nicotine had been used, nor 
was the flavor of grapes or wine affected. Nicotine is always preferable 
to arsenicals which should never be used after the middle of July.

Authorities are quoted to show that a carefully prepared nicotine 
spray applied at the proper time communicates no taste to musts and 
wines, at any rate when copper sulphate is nearly, or entirely absent. 
The spray solution should therefore contain only nicotine and soap.

Nicotine-soap gave very fine results. The spray was made up of 
20 gal. of a l/2-percent lime-copper-sulphate solution, 4 l/2 oz. of 
90-percent purified nicotine and 2 lb. of soft soap. Nicotine-soap is 
mainly a control of the second generation and must be applied immediately 
after the moth flight is over.
