Anticarsia g-eismatllls &bn.). the velvetbean caterpillar 
A low concentration of chlordane showed some premise for the control 
of this insect in Louisiana in 1946, but the next year it gave very little 
control after five day 6. — Dugas j»t a^.. ( ll6 t 118 ) . 
A 1-percant chlordane dust was less effective than 1-percent DDT and 
1-percent ganma benzene hexachloride dusts in controlling caterpillars on 
alfalfa in Alabama in 1946. All dusts were applied at the rate of 15 
pounds per acre. In 1947, 5-percent chlordane dust gave 68 percent control 
of the larvae on soybeans 48 hours after dusting at the rate of 25 pounds 
per acre.— Arant (21) . 
Cjrphis unipuncta (Haw.), the armyworm 
In preliminary laboratory tests chlordane was much less toxic than 
DDT.-- Bishopp Q2). 
Rellothis armigera (Hbn. ) , the tomato frultworm, the bollworm, the corn 
earworm 
A field test on tomatoes made in Louisiana in 1946 showed 2-percent 
chlordane dust to be inferior to cryolite and calcium arsenate. — Floyd 
A 5-psrcent chlordane dust gave controls of 41.6 and 38.7 percent in 
two tests on western Long Island in 1948. The effectiveness of chlordane 
was less than that of DDT, TDE, parathion, or methoxychlor . — Butler and 
Carruth (&) . 
Dusts containing 5» 10 • and 20 percent of chlordane failed to give 
adequate control of the bollworm. — Arant (20) ; Kulash ( 27^ ) • 
In laboratory and cage teats in Texas a 20-percent chlordane dust 
was less effective against the bollworm than DDT or toxaphene. — Ivy and 
Eving (2^2). 
In Texas diu-ing 1947 a 20-percent chlordane dust was as effective as 
calcium arsenate, but less effective than a 20-percent toxaphene dust ox 
a 5-percent DDT plus 3-percent gamma benzene hexachloride sulfur dust in 
controlling bollworm. — Gaines and Dean (l6ii) • 
An emulsion of chlordane atomized on corn ears showed promise against 
the corn earworm. — Bishopp (32). 
In Horth Carolina in 1947 a 5-percent chlordane dust gave 40.4 per- 
cent clean ears as compared to 75*5 percent clean ears resulting from the 
use of 0.25 percent DDT in mineral oil. Of the untreated ears 27.0 per- 
cent were clean. — Kulash (273,) « 
In Florida in 1947 a 5-percent chlordane dust and a 50-p«rcent chlor- 
dane wet table powder at 2 pounds per 100 gallons of water were inferior to 
DDT and methoxychlor dust and sprays in controlling earworms on sweetcorn.— 
Kelsheimer (249).
