How much Merit insecticide do I need?
I am a bit confused about how much product I would need. I have used Bayer Advanced and they ask for the distance around the tree and then to use 1oz per inch of distance. These instructions are quite different with this product. You have me dividing that distance(circumferance)to get the diameter. According to your formula I have 7 trees with a combined DBH of 82.72. Which at a rate of 1.4 tsp would mean about 116 teaspoons. So how many teaspoons are in the 2oz jar of product.
One 2oz jar of Merit WP contains enough product for about 30 cumulative inches of tree trunk diameter (at the highest concentration for systemic control). These small 2oz jars are usually purchased by people who only have to treat one or two trees or shrubs. When you need to treat several trees the Merit 75WSP envelope is usually the way to go. One envelope of the Merit 75WSP contains enough product for about 96 cumulative inches of tree trunk diameter at the highest concentration. 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.
