Intended for an audience of pesticide users, this film demonstrates 

 the results of carelessness in the handling of these poisons. The 

 introduction to the film details the development of effective pesti- 

 cides, and a short sequence in the laboratory shows what minute 

 quantities are lethal to fish. The major portion of the film deals 

 with a single case of misuse. 



Pesticides, incorrectly applied so that the residue was washed 

 into a small stream, destroyed not only the valuable game fish it 

 contained but the insects which served as food for the fish. The 

 concentration of pesticides in the water was also a possible hazard 

 to larger animals and man. The stream was closed, and the process 

 of rebuilding its insect and fish populations may take years 

 provided new contamination does not occur.

Chemical research on the control of insect pests which threaten 

 crops is documented in this film. A complete picture of the various 

 methods and problems involved is given, and the necessity for 

 careful research emphasized. The film shows that ecological factors 

 must be considered equally as important as efficient mass spraying 

 techniques. This timely problem of pests and pesticides is treated 

 with a thorough understanding.
