Iris Borer Spray

Iris Borer Spray


Bonide intoduced this spray as a Tree and Shrub spray. It is a systemic which means it soaks into the plant. While it is not specifically noted as a iris spray, it is being widely used for borer control in irises. It is mixed 4 tablespoons to the gallon. Application is by mixing in a sprayer or mixed in water and used as a drench. We reccommend applying it once a week for 3 weeks in the early spring as temperatures reach 60 degrees. You should use a spreader sticker with this product. You can refer to our recent newesletter #7 for more application details. You can ask for the newsletter copy by e-mail if you are not on our newsletter list.
