Fish oil (0.25 percent) was about as effective with nicotine 
sulphate (l to 200) as mineral oil, and this mixture may prove useful 
against the second "brood, in view of the difficulty experienced in the 
removal of residue when nicotine sulphate and mineral oil has been 
applied after lead arsenate. It is concluded that lead arsenate remains 
the most satisfactory single spray material for the codling moth, and 
lead arsenate and fish oil the best combination.

Tannic acid 1 lb. to 50 gal. plus Nicotine 50 at the rate of 0.5 
pt. to 50 gal. gave considerable control, but is considered unsuitable 
for use under South Carolina conditions.

Many growers used the nicotine-oil combination for the second 
brood, with satisfactory results, but this interfered somewhat with 
cleaning the fruit, especially if heavy applications of lead arsenate 
had "been made earlier. A few growers used this combination after the 
first cover spray with fair success, but such a schedule is expensive, 
and in many instances it cannot be employed, owing to injury by the oil.

In the experiments nicotine t annate and nicotine were used. 
Among the various insecticides tried, nicotine with oil was one of 
three which proved superior to all others. While nicotine with oil 
possesses useful properties, its field of usefulness is restricted 
(p. 221).

In the spray program nicotine sulphate (l pt. to 100 gal. spray) 
is used to control red bugs. Nicotine is also used in the second or third 
cover sprays to help control the codling moth.
