Abstract
Ethoprop, oxamyl, PP 156 [1,4-dithiepan-6-one N-[(methylcarbamoyl)oxy]oxime], fenamiphos, carbofuran, AC 64,475 [2-(diethoxyphosphinylimino)-1,3-dithietane], Bunema M, CG 12223, aldicarb, aldicarb sulfoxide and aldicarb sulfone were tested for their effects on hatching and emergence of larvae from cysts of H. schachtii [major pest of sugar beet]. The oxime carbamates and carbofuran inhibited hatching, but this response was reversed by removing the chemical treatment. Inhibition of hatching by Bunema M and all organophosphates tested was irreversible.
