Tank -mixed nicotine tannate (cf. Rev. Appl. Ent. (A) 19: 385; 
20: 515), with 3 lb. powdered sweet skim milk per 100 gal., was tested 
as a substitute for arsenicals against the codling moth. The control 
obtained was satisfactory but slightly inferior to that resulting from 
the use of lead arsenate sprays. Should it become possible to increase 
the retention of nicotine tannate on foliage and fruit, this substance 
will probably become the preferred substitute (p. 677). Dusts and 
sprays containing nicotine tannate gave some promise but could not be 
recommended as a substitute for magnesium arsenate against the Mexican 
bean beetle ( Epilachna varivesti s Muls.) (p. 678). 
The application of a strong spray of soap and nicotine merely 
stupfied the weevils Diorymerellus laevimargo Champ, (p. 673). 
Young potteo gardenia plants, treated with a spray containing 5 percent 
coconut fatty-acid soap and 0.25 percent free nicotine (40-percent) and 
dipped in the same material prior to sotting out, remained comparatively 
free of the mealybug Pseudococcus citri Risso (p. 679) .

Excellent control was obtained against the fireworm with nicotine 
tannate at 1 to 500, when used at the rate of 1 to 400 against the 
cranberry fruitworm the number of injured berries was less than 0.5 
percent. The season's work indicates that nicotine tannate is a 
more effective control for both the cranberry fireworm and the cran- 
berry fruitworm than nicotine sulphate (p. 66) .

In codling moth studies, nicotine tannate showed promise of 
good control as a supplementary insecticide. It wis the most suc- 
cessful of the insecticides tried against the onion thrips ( Thrips 
t abaci Lind.) (p. 450). Some control of psyllids ( Paratrioza c ockcrelli 
Sulc. and Empoasca ab rup t a DeLong.) was obtained with bordeaux - oil - 
nicotine sprays.
