Abstract

Carbaryl and endosulfan provided good residual protection of oats from the cereal leaf beetle, Oulema melanopus (L.), and GS 15-171 [1-[b (carbethoxy)-ethyl]-3-methyl-5-(N-dimethyl carbamyl-oxy)-pyrazole], TD 8550 [S-(N-methoxy-carbaryl-N-methylcarbamoyl-methyl) dimethyl-phosphonothiolathionate] and Supracide® $[{\rm S}\text{-}(2\text{-}\text{methoxy-}5\text{-}{\rm oxo}\text{-}\Delta ^{2}\text{-}1,3,4\ \text{thiadiazolin-}4\text{-}{\rm yl})\ \text{methyl}\ {\rm O},{\rm O}\text{-dimethyl phosphorodithioate}]$ proved promising for this use. Padan® [S,S'-[2-dimethyl-amino) trimethylene] bis (thiocarbamate), hydrochloride] and Sandoz 52135 [O-methyl-O-[2-diethylamino-6-methyl-pyrimidyl-(4)]-N-methyl-phosphoramidate] gave only fair initial control, and Orthene® [O,S-dimethyl acetylphosphoramidothioate] was poor, against this pest. Endosulfan, TD 8550, Supracide®, GS 15-171, Sandoz 52135, and Orthene® gave some control of aphids (primarily the English grain aphid, Macrosiphum avenae (Fab.), while carbaryl and Padan® did not.
