Unidentified wireworms 
Chlordane was tested against wireworms in lima bean fields in Orange 
County, California. It was applied April 20, 19^7. at the rate of 10 pounds 
per acre and the beans were planted 10 days later. In August all treated 
plots were better looking than the untreated plots. Ethylene dibromide 
gave the best control against wireworms and nematodes of all materials 
tested (DDT, benzene hexachloride, chlordane, and ethylene dibromide).— 
Crosby (82). 
In preliminary tests in California chlordane proved effective for the 
control of wireworms when used at the rate of 10 pounds of technical grade 
chlordane in 20 gallons of solvent (such as benzene) per acre. The material 
was drilled into the soil to a depth of 6 inches using 12 inch spacings in 
the same manner as ethylene dibromide. — Lange ( 2§i) • 
In Connecticut in 19^7 chlordane applied as a wettable powder by the 
conventional potato sprayer resulted in excellent tobacco stands at 5 and 
2 1/2 pounds per acre even in cases in which more than half of the plants 
in comparable control plots were down. There was no off-taste or impaired 
burning quality of cured tobacco leaves secured from these plots. Chlor- 
dane produced an off-flavor in potatoes but to a much milder degree than 
BHC. — Greenwood ( 195 ): Turner (k6l), 
Chlordane was inferior to parathion and benzene hexachloride in con- 
trolling vireworms attacking newly planted sugarcane in Florida. When 
chlordane was mixed with fertilizer and applied immediately, good control 
was obtained. —Hayslip ( 210 . 211). 
Chlordane offers some promise in wireworm confc*ol. Apply as a dilute 
dust to the soil surface and then disc or harrow into the top four to six 
inches of the soil. Five pounds of chlordane is the usual dosage. —

Meloidae 
Decapotoma lunata Pall., C.M.E. beetles 
In laboratory tests 5-percent chlordane dust killed all beetles in 
Zhe hours when applied at the rate of 0.22 mg./sqL. cm. (20 pounds per 
acre). —Petty (363). 
Eoicauta pennsylvanica (Deg.), the black blister beetle 
In Indiana in 1946 chlordane proved ineffective against the black 
blister beetle . —Could (186) .
