Abstract
Full- and half-strength Silvisar 510 injected trap trees gave mortalities of 94 and 90%, respectively, for Dendroctonus rufipennis (Kirby). Half-strength treated trees received more attacks and also had lower arsenic concentrations in the phloem and cones than did the full-strength treatments. The tenth and quarter-strength treatments resulted in spruce beetle mortalities of 40 and 70%, respectively. Injection of trees in late August, followed by felling one mo later, is preferable to earlier or later injection and felling times.This publication has 1 reference indexed in Scilit:
