Dosage mortality regression analyses were completed for 28 candidate insecticides with 6th-stage larvae of Euxoa auxiliaries (Grote) and their oral toxicities were compared with endrin as the standard. As a group, the pyrethroids were more toxic than the organophosphorus insecticides. Bioethanomethrin and permethrin were more toxic than the endrin standard, whereas cypermethrin and fenvalerate were slightly less toxic. Fenpropanate and FMC 26021 ((5-benzyl-3-furyl) methyl(+)-cis-2,2-dimethyl-3-(2-methyl-I-propenyl) cyclopropanecarboxylate) were 2 times, and chlorpyrifos, methamidophos, endosulfan, BAY 77049(0,0- diethyl-0-(2-quinoxalinyl) phosphorothioate), leptophos, and monocrotophos were 3–4 times less toxic than the standard. The remaining insecticides were 5–30 times less toxic than endrin.

In greenhouse tests, permethrin, fenvalerate, cypermethrin, and fenpropanate at 0.14–0.28 kg/ha as sprays to barley plants gave control comparable to endrin at 0.28 kg/ha. However, as soil treatments, the pyrethroids were more effective than endrin at comparable rates of application. Endosulfan, chlorpyrifos, leptophos, and monocrotophos required 0.56 kg/ha to produce control comparable to endrin and, except for endosulfan, these insecticides were less effective as soil treatments. Microplot tests on barley confrrmed the effectiveness of the pyrethroids at 0.14 kg/ha both for control of the army cutworm and for significant reduction in plant damage.
