In the Everglades area of Florida a 3~percent chlordane dust gave 6 
percent of ears with no worm damage; a 5-percent DDT dust gave 39 percent; 
and 2.7-percent DDT in oil gave 100 percent. A 40-percent chlordane 
emulsion, 1 quart to 100 gallons of water, was about equal to DDT emulsion, 
"but less effective than parathion (2 pounds of 15 percent wettable per 100 
gallons of water) in preventing tomato injury by the tomato fruitworm. — 
Hay slip (211). 
In laboratory tests 5 percent chlordane was slightly less toxic than 
DDT, natural cryolite, or 2 percent parathion. — Petty ( 3 63 ). 
A 1-percent solution of chlordane in refined mineral oil (Saybolt 
viscosity 185-195 sec. at 100° F.) injected into tips of ears of Golden 
Cross Bantam sweet corn in southern California was slightly less effective 
than 1-percent DDT and TDE solutions. These materials all gave good con- 
trol when applied as high pressure aerosols. — Anderson and Hashe (18). 
In Louisiana, in 1948 chlordane dust, applied 8 times at an average 
dosage of 12 pounds of dust per acre per application, failed to control 
insects on Mexican June corn planted August 13. The plants were more 
than 50 percent destroyed and no ears were produced. — Floyd ( l44 )» 
A 5-percent chlordane dust gave less than 50 percent worm-free ears 
in tests with sweet corn in North Carolina. Cotton treated with 5 percent 
chlordane was as heavily infested with bollworms as untreated cotton. — 
N. C. Agr. Expt. Sta. (353). 
In the Lower Eio Grande Valley of Texas a 5-percent chlordane dust 
(4 dustings at weekly intervals) gave 4-5 percent earworm injury as com- 
pared to 79 in the untreated plants. A spray of 4 pounds 50-percent wet- 
table chlordane per 100 gallons of water gave 2-percent whorls with live 
larvae compared to 45-percent in the untreated. — tfene and Blanchard (4. 9 , 5 ) » 
Heliothis ononis (Schiff), the flax bollworxn 
Chlordane dissolved in benzene-kerosene mixture and applied in a 
spray tower had very slight effect on the larvae. — Brown jgt ai. (50). 
LaT>hygma frugiperda (J. E. Smith), the fall armyworm 
A 5"*percent chlordane-pyrophyllite dust, applied 3 times to a total 
of 28 1/4 pounds per acre, gave a control of 98 percent of armyworms after 
72 hours. A bait containing 1.5 percent of chlordane, 5 percent of xylene, 
and 11 percent of oil in bran killed 100 percent of the armyworms after 24 
hours in cage tests, and 93 percent after 48 hours in field tests. Chlor- 
dane dust failed to control late fourth-instar larvae. — Brooks and 
Anderson (48) . 
In tests made on field corn at Norfolk, Virginia, in July 1948, a 
3-percent chlordane dust reduced the number of worms 57 percent below the 
check in 24 hours and increased the percentage of uninfested plants above
