Abstract |
The effective use of insecticides is dependent upon the availability of efficient and durable applicators. Many hundreds of sprayers, dusters, fumigators, and other devices have been designed, manufactured, and marketed; yet, equipment available today is generally inefficient and easily damaged. Acutely aware of this, manufactorers are expending great effort in research and development, but efficient applicator equipment remains one of the great unsolved problems of public health engineering. The paper discusses the problem of obtaining efficient applicator equipment. (Author Modified Abstract) |
