Insecticides 
Insecticides are substances used to destroy injurious or 
troublesome insects. In practice, the term is often made 
to include also substances used to repel such insects. The 
insects may be injurious to man, to the lower animals, or 
to plants. Many of these substances are inorganic, but 
a number of them consist of parts or products of plants, 
and of these it is our intention to form a complete collection.
