Reduced Application Rates of Orthene Forest Spray Give Less Effective Spruce Budworm Control in Maine – 1978

Problem Addressed: Spruce Budworm

Goal(s)/Objective(s): Compare 4 different concentrations of acephate (tank mixes) applied at different volume rates.

Key Findings: Reducing application rates of Orthene Forest Spray formulations from 64 fl oz per acre to 32 fl oz per acre or less decreased budworm control in Maine

Alkali Solubility as an Indication of Decay in Diseased Wood

Problem Addressed: Spruce Budworm infestation

Goal(s)/Objective(s): Determine if, in fact, the 1% alkaline solubility test could serve as a valuable empirical measurement of decay in wood to be used in pulping and to obtain experimental data to be used in a future study of the effect of decay on pulp yield and strength properties (using 5/8" and 7/8" chips in pulping)

Key Findings: The 5/8" and 7/8" chip samples led to accurate and reproducible results. Since 5/8" and 7/8" chips are typically considered to be part of the accepted chips used in industrial pulping, the 1% NaOH solubility test could serve as a useful and reliable measurement of decay of wood to be used in industry.
