| dc.description |
Two concentrations of dimethoate were applied with a hydraulic ground
sprayer to cone-bearing Douglas-fir and grand fir trees. Single application
(mid-June) and a double application (mid-June and mid-July) were
compared. Three of the four treatments applied to Douglas-fir resulted
in a significantly higher number of sound seeds produced per cone
compared to untreated cones. No seed protection was exhibited in the
grand fir treatments. |
