Curly willow has borers. Would like to save tree. How much product would it take? Tree is way to large for me to spray.
It is quite possible that Merit 2F Insecticide would work on what it eating your tree as the tree will absord the product. So insects feeding on the tree will also injest the product. Keep in mind the product may take up to 6 weeks to work. It would be best to check with your extension office to identify the insect & ensure the product would work. The product states to use 0.2 fl oz (6 mL) per inch of trunk diameter
