(4.8 percent of rotenone) plus 1 quart of oil gave 95#5 percent, Black 
Leaf 40 in oil 98#5 percent, and lead arsenate 97.4 percent control. 
A combination spray of derris with a small amount of lead arsenate and 
oil provided effective control. In 1942 both nicotine and rotenone 
sprays again proved highly effective when applied every week or 10 days 
during the period of codling moth activity. The three most effective 
mixtures were 3 pounds of Black Leaf 155 plus 1 quart of oil, 2,5 pounds 
of derris (5 percent of rotenone) plus 1 quart of oil, and 3 pounds of 
lead arsenate plus 3 pounds of lime per 100 gallons of spray, each with 
a comroeroial spreader » — Harman (261-264) • 
Derris, cube, and pyrethrum in 1942 gave promise as substitutes 
for arsenicals.— Parrott (457 ) . 
In Delaware tests to determine the value of substitutes for ar- 
senicals against the second-brood codling moth included a spray con- 
taining 1.5 pounds of Black Leaf 155 and 1.5 pints of D-X (a rotenone 
and pyrethrum product) in 100 gallons of water. This spray gave 
53.6 percent of clean fruit while a lead arsenate spray gave 55.1 per- 
cent.— Stearns (564 ) • 
Tests for substitutes for lead arsenate, conducted in Pennsylvania 
in 1941, included three treatments in which rotenone products replaced 
two-thirds of the lead arsenate. None of these treatments were so ef- 
fective as lead arsenate on the two varieties of apples sprayed.— 
Worthley (701). 
In Massachusetts a modified schedule, employing a commercial py- 
rethrum-rotenone combination containing lead arsenate at reduced 
strength, practically eliminated codling moth damage.—Bourne (72, p. 36). 
In Germany two poison baits were tested, one a derris prepara- 
tion at a concentration of 1 percent with 0.15 percent of soft soap and 
4 percent of sugar, and the other containing 0,4 percent of lead 
arsenate with 4 percent of sugar. Moths confined with the poison died 
within 9 days in the laboratory and 11 days in the field. In an apple 
orchard sections of 83, 317, and 36 trees were sprayed 3 times, with 
the arsenical bait, the derris bait, and the normal arsenicel spray di- 
rected against the larvae. The percentages of uninfested apples from 
the three sections were 62, 67, and 49, respectively, while only 11 
percent of the apples from an unsprayed orchard were uninfested. No 
danger is likely to accrue to honeybees from the use of derris bait sprays.
