heavy applications of lead arsenate for first brood sprays. Fish 
oil-nicotine combinations did not interfere with the removal of either 
arsenic or lead and seemed to be advantageous when sodium silicate 
washing solutions were used.

Tests carried out from 1930 to 1932, some of which have already 
been noticed (Rev. Appl. Ent. (A) 20: 34), have shown that lead 
arsenate, 2 percent summer oil, and a combination of 1 percent summer 
oil and nicotine sulphate (3/4 pt. to 100 gal.) will give good con- 
trol in heavily infested orchards. The use of non-arsenicals in the 
summer sprays kept the arsenical residues in most cases within the 
limits of tolerance.

An oil-nicotine combination in second-brood cover sprays has con~ 
tinued to give as good control as lead arsenate.

Nicotine tannate used as a. substitute for lead arsenate was of

Farrar determined that 1 percent summer oil with nicotine 
sulphate (1:800) has proved a satisfactory substitute for arsenicals 
against the second and third broods of the codling moth. Flint found 
that in years when this insect is excessively abundant, oil-nicotine 
sprays must he applied at intervals of 7 to 10 days when second-brood 
hatching is at its maximum.
