Goal(s)/Objective(s): Determine the initial concentration and the persistence of Dylox residues in the forest environment and in water
Key Findings: Detectable residues of Dylox persisted on leaves, twigs and in forest litter for at least 106 days after spraying, although the levels of residues decreased rapidly during the first week
Goal(s)/Objective(s): Describe how Quebec put into application the results of specific research in its battle with the Spruce Budworm on several million acres
Goal(s)/Objective(s): Determine optimum swath widths and spray application rates which achieve a uniform coverage of 20 to 25 drops per square centimeter at the top of the forest canopy under various meteorological conditions for five different types of spray aircraft.
Goal(s)/Objective(s): Determine the efficacy of reduced application rates and dosage levels in reducing larval populations of the budworm and minimizing the amount of defoliation occurring in a given year
Recommendation: A single application of a finished spray of mexacarbate and kerosene, applied at a rate of 0.25 gallon/acre containing 0.15 lbs. AI, when budworm larvae are in the 4th and 5th instars, will effectively reduce budworm populations and minimize defoliation on balsam fir
