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
