decidedly more effective if applied in second brood sprays. The 
combination of oil, 1 to 100, and nicotine sulphate (1/2 pt. to 
100 gal.) has given a control of the codling moth equal to that of 
lead arsenate, 1 lb. to 50 gal. In view of the removal of residues, 
combinations of mineral oil or fish oil with lead arsenate should 
be applied in first-brood sprays and mineral oil-nicotine sulphate 
combinations in second-brood sprays.

Lead arsenate formed the common basis of the most satisfactory 
spray mixtures; of the non-arsenicals tried, a combination of white 
oil and nicotine sulphate proved the best. A mixture of nicotine 
sulphate and tannic acid (nicotine tannate) gave little control.

Nicotine sulphate (1:800) combined with oil emulsion gave 
control comparable to lead arsenate.

This is a revision of previous bulletins (Rev. Appl. Ent. (A) 
12: 247; 18: 384), the principal additional information dealing with 
the use of oil emulsions combined with lead arsenate sprays against 
the first brood or with nicotine sulphate against the second brood.
