Yes, you can use Merit 75 WP on trees that aren't infected with anything; however, be aware that there is a limit on how much product you can use per year. As a low cost alternative we recommend Dominion 2L which has the same active ingredient as Merit and treats the same insects. One bottle of Dominion 2L contains enough product for about 137 inches of tree trunk diameter at the highest concentration, where one 2 oz jar of Merit 75 WP contains enough product for about 30 cumulative inches of tree trunk diameter (at the highest concentration for systemic control).
