Cf the many non-lead arsenicals and non-arsenical s, among 
which were oils and nicotine sulphate, used singly arid in various 
combinations in the experimental plots in 1933, none gave promise 
as an immediate substitute for lead arsenate (p. 2 30).

Recent work in New York showed lead arsenate to "be the most 
reliable single material for combating the codling moth. The com- 
bination of nicotine and oil has given most promise as a substitute, 
(p. 144).

27: 222-225. 
Among the materials that gave the best control with 5 summer 
applications was 3 lb. lead arsenate in the first codling moth spray, 
followed by 3 qt . of summer oil and 1 pt. of nicotine sulphate in the 
next four applications. These amounts "ere used in 100 gal. of water. 
The results were as follows:
