Project: Testing the effectiveness of low-dose application rates of TM-Biocontrol-1, the natural virus of the Douglas-fir tussock moth, Orgyia pseudotsuga (McDunnough).
Report: MacLauchlan and Ragenovich; SERG Project 2009-10.
The objective of this trial was to evaluate the effectiveness of low-dose application rates of TM-Biocontrol-1, the natural virus of the Douglas-fir tussock moth (DFTM), Orgyia pseudotsugata (McDunnough). If a lower dosage rate than the registered rate is successful, this would extend the useable amount of this limited resource currently in stock.
