Paul Hermann Muller discovered the insecticide effect of DDT in 1939 but the compound is known from 1874.
DDT (Dichlorodiphenyltrichloroethane) was first synthesized in 1874, but it's insecticide properties weren't discovered until 1939.After finding that DDT was harmful to animals and humans, it was outlawed for most uses in the U.S. in 1972. Subsequently, it was banned for agricultural use worldwide in the Stockholm Convention. So, the short answer is, there should not be *any* DDT present on plants.
