Low-toxicity organophosphorous insecticide:Sumithion
|
Sumithion was developed by the Sumitomo Chemical Company in 1960. It is a very effective insecticide against the larvae of the rice borer, the house fly,cockroaches, the rice stinkbug (Oebalus pugnax), caterpillars of the cabbage butterfly (Pieridae) and other domestic and agricultural pests.The toxicity of Sumithion is low for humans and also for mice up to an oral dosage of LD50 870mg. Sumithion must be applied frequently since it decomposes rather easily and has low residual effect.
