Dean ( l64 . l6? . l63) . In several states dusts containing 10 percent chlor- 
dane gave boll weevil control equal to that given by calcium arsenate, pre- 
vented build-up of aohids, and killed sone weevils developing in fallen 
squares. In other cases very erratic results have been obtained. Con- 
flicting results were obtained regarding the practical benefits of killing 
weevils in squares and bolls. — U. S. Bur. Ent. and Plant ^uar . ( 466 . 467 .) « 
In South Carolina a dust containing 10 percent of chlordane and 5 per- 
cent of DDT, applied at the average rate of 10 pounds per acre - application 
has been recommended by the state agricultural experiment station for the 
control of the boll weevil and other insects on cotton. — S. C. Agr. Exot. 
Sta. (431). 
Reports from county agents in South Carolina on the value of chlordane, 
BHC-chlordane , and toxaphene-chlordane for cotton insect control have been 
summarized by Sparks ( 432 ) . 
Anthonomus signatus Say, the strawberry weevil 
A 5-percent chlordane dust reduced injury 85. 5 percent. — Christ and 
Driggers (22) • 
A 5-percent chlordane dust gave excellent control of this weevil on 
strawberries in Kentucky and doubled the yield. — £y. Agr* Expt. Sta. ( 2 58 ) :

In New Brunswick, Canada, chlordane proved less effective than DDT. —

Brachyrhinus 11/^usticl (L.), the alfalfa snout beetle 
In several field trials chlordane appeared promising for alfalfa 
snout beetle control and proved superior to the standard peanut shell bait. — 
Gyrisco fit al. (200 ) . 
Brach yrhinus ovatus (L.), the strawberry root weevil 
A 5-percent chlordane dust, applied at the rate of 10 pounds toxicant 
per acre to a block of 12-15 yeal old hemlock trees, killed all weevils 
within 3 weeks. — Schread ( 4-11 ) . 
Ceutorhyncus assimilis (Payk.), the cabbage seedpod weevil 
In Washington a chlordane dust was inferior to a 0.5-percent benzene 
hexachloride dust. — Eide ( 132 ) . 
Chal codermus aene us Boh., the cowpea curculio 
In Texas two applications of a 5-percent c^ilordane dust reduced the 
percentage of infested pods on Black Eye peas from 15»3 (untreated) to 4.0, 
and three applications reduced the infestation to 2.0 percent. — Wane ( 492 ) .
