the check 46 percent in 24 hours and 6l percent in 48 hears. In another 
test in a pasture a 5-percent chlordane dust killed 62 percent of the army- 
worms. Parathion and DDT gave the test control. — Hof master and Greenwood 
(225). 
Fire percent chlordane dust was fairly effective in controlling the 
armyworm but affected the corn adversely. — Tissot and Kuitert ( 456 ) . 
Chlordane dust was effective against this insect on tomatoes in 
Florida. — Kelsheimer (248). 
For the control of this insect attacking lawns in Florida it is 
recommended to use 2 pounds of 50-percent chlordane wettable powder per 
100 gallons of water per acre or a 5-P©rcent chlordane dust.- Kelsheiaer 
Chlordane, applied as an emulsion to corn ears, imparted an odor 
noticeable at harvest time. Dusts gave unsatisfactory control, but chlor- 
sLase emulsion (l ml. plus 0.5 ml. of emulsifier, 20 ml. of white mineral 
oil and water to make 100 ml.) gave consistently good control of this 
species and the corn earworm in sweetcorn. — Blanchard and Chamberlin (35) . 
Chlordane wettable powder (50-percent) at 2 pounds per 100 gallons 
of water gave good control of fall armyworms in the buds of corn. A 
poisoned wheat bran containing 5 percent of chlordane also gave good con- 
trol.— Hayelip ( 210 . 211 ). 
A 5-percent chlordane dust, applied at the rate of 10 pounds per acre 
to Ladino clover, killed 1/2 the larvae two days after dusting. No phyto- 
toxicity was observed. — Kulash ( 274 ).

Perldroma margaritosa (Haw.), the variegated cutworm 
In preliminary laboratory tests chlordane was much less toxic than 
DDT.— Bishopp Q2) . 
Platysenta sutor (On.) 
A 5-percent chlordane dust killed 24.2 percent of the larvae on celery 
in Florida in 24 hours.— Hay slip (211). 
Prpdenia er ldania, (Cram.), the southern armyworm 
In laboratory tests a 1-percent chlordane dust killed 96.? percent of 
medium larvae in 2 days. — Sun e_t aj,. ( 449 . 450 ) . 
In fumigation action against larvae chlordane was superior to gamma- 
BHC and DDT, "but in contact action and stomach action it wa6 inferior. — 
Sun e_l ai. (448).
