Spraying with DDT

Sorry about all the posts from the July 22 1948 edition of the Toronto Daily Star, but I found so much in that paper!

Here’s one final news item:


DDT was developed as an insecticide; its year of peak usage was 1959. It was found to have toxic effects on the environment, particularly on the eggshells of certain species of birds; Rachel Carson’s book, Silent Spring, brought environmental problems of this sort to public attention.

DDT was banned for agricultural use in the United States in 1972; it is still occasionally used for vector control.
