An interview with Dr. Charles Petty LSU pathologist, indicates that toxicity of boll weevil and some other insecticides has been definitely linked with fatalities and illnesses in the wake of aerial spraying; and that progress has been made in instruction as to hazards, first-aid and safeguards. No fatalities have occurred since 1955 but 13 persons were hospitalized in 1956 and 1957 in Louisiana,
The possibilities were brought to attention in Mississippi in 1956, with special reference to accidents, and strange reactions, among "duster" pilots.
It is the "duster" pilot also who has aroused chief concern in California, where a similar educational program is under way in Kern county among both pilots, farmers and other handlers of insecticides. In the case of pilots, inhalation of phosphoric fumes from spray tanks is suspected of having dulled the senses of men who crashed into objects they previously were able to avoid.
It is no secret that the new methyl parathion insecticide is toxic, like other organophosphor-ous compounds. It is said to pass easily through the skin and in relatively small quantity produce symptoms, including eye effects, that certainly wouldn't help a "hedge-hopping" aviator.
Continuing education for safety will be necessary because Louisiana farmers have to turn largely to this compound due to the grow-. ing immunity of weevils to chlorinated hydrocarbons. This same evolutionary defense mechanism among insects may force trial of a rotation system for insecticides, and the changing precautions that uo with it.
