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
Goal(s)/Objective(s): Present spruce budworm survey and evaluation data gathered by the Insect and Disease Management Staff.
Key Findings: A future budworm outbreak in Maine is likely to vary considerably from the recently concluded outbreak. Budworm is certain to return and provide new management challenges to Maine landowners
Goal(s)/Objective(s): Evaluate the spruce budworm situation and provide technical assistance in the planning and conduct of suppression projects for the Passamaquoddy Tribe
