Popis: | The insecticidal value of sulfur, in the elementary form, is receiving increasing recognition especially for high temperatures. Such increase in usage is at least in part, due to improvements in the process of manufacture, particularly the very finely ground sulfurs and precipitated sulfurs. The latter are becoming available in increasing quantities and at low prices through the recovery of sulfur in purification processes. Very large potential supplies of this form of sulfur are available as the demand may justify their recovery. Experimental results are given of the value of sulfur dust for the control of thrips and the larval stage of scale insects. |
