Show New Dusting Methods Tested in Michigan Charging Fungicides Revolutionize Spraying Fighting Insects and plant diseases which damage farm crops may be revolutionized by charging dust particles in fungicides and Insecticides with Michigan researchers reported Laboratory tests by Michigan State College researches show charging of dust particles of normal dusting compounds gets five to ten times better coverage than through usual dusting A. W. head of the Henry D. assistant in agricultural engineering at is shown experimenting with apples in the electrostatic dusting agricultural engineering says field tests will be made this summer to try the new process Fine dust particles of the fungicides and insecticides are charged with from to volts as they emerge from the nozzle of a regular commercial dusting This high charge Is held for several With dusts blown at a velocity of a mile a it permits them to travel a great distance before losing the electric Engineers estimate the cost of necessary electrical attachments for the ordinary four-row duster would run around |
