should "be applied in July when most of the second generation moths 
are flying and ovipositing on the leaves. Melon aphids ( Aphis

A comparison of pure nicotine wash and nicotine sulphate has 
shown the latter to be quite as effective, to have more lasting powers 
when mixed with soft soap, and to be much cheaper. Nicotine wash de-

cella ) and nicotine sulphate with soap destroyed 92 percent.

Tests with lead arsenate and calcium arsenate in the spring were 
ineffective; "but 1 oz. 96-percent nicotine, l/2 lb. soft soap and 10 
gal. water killed over 80 percent of the larva.e, and 1 oz. nicotine 
sulphate, 1/2 lb. soft soap and 10 gal. water, over 90 percent. The 
latter took 48 hours longer to have the same effect as the former, but
