DDT is a pesticide that was used to kill bugs. It's bad for the environment because it was killing the animals that would eat those bugs once they were dead, and the population of those animals was decreasing fast. It was banned once scientists realized what it was doing to the animals.

∙ 7y agoIt depends on the environment you consider. If you are concerned that your environment has too many malarial mosquitos and similar disease transmitting insects it is a very good thing. If you want a pesticide that is generally harmless to many animal species (us included) it is a good thing. If you are worried about the bioaccumulation of materials in birds with subsequent problemss with sterility, thin egg shells and similar, it is a bad thing.

This led to ban in DDT in many countries.

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.
