This book was released on 1992 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: A detailed assessment of spray deposition and efficacy of Dipel 6AF and Thuricide 48LV was carried out as part of the 1988 western spruce budworm control program. An analysis of covariance model was used in an attempt to examine the relationship between deposit density and field efficacy (larval mortality and defoliation) for the two formulations. The model could not be justified and relationships between the variables were investigated using chi-aquare analysis.

This book was released on 1993 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents results from a series of trials to evaluate replicate test sites, two treated with fenitrothion followed by an application of Bacillus thuringiensis (B.t.) and two treated with two applications of B.t. A team of Cessna 188 aircraft equipped with Micronair AU4000 rotary atomizers applied all spray treatments; there were also unsprayed control plots for comparison. The investigators conducted biological evaluations of 60 selected balsam fir trees at each treatment site to record such information as number of buds and shoots, defoliation category for each bud/shoot, number of spruce budworms, and state of development of each bud/shoot. They also determined spray deposition. The report concludes with an assessment of the comparative efficacy of the treatments studied on spruce budworm mortality.
