Mountain Pine Beetle Pesticides Registered in South Dakota

Pine BeelteSDDA advises landowners to carefully consider the preventative treatment options available to protect their pines from mountain pine beetles.

You MUST read the label of each product you are considering to ensure you are using the correct product for your situation. Not all products are registered for all uses. You MUST read and follow all label precautions, warnings, safety recommendations and use instructions. The label is the final authority for a product?s use on a particular plant or pest.

Information about the labeled General Use Pesticide Products can be found here.

Information about the labeled Restricted Use Pesticide Products (Certified and Licensed Applicators only) can be found here.

According to Dr. John Ball, SDSU Extension Forestry Specialist, there are no effective systemic pesticide treatments that will kill the adults or larvae inside the tree. Pesticide treatments are limited to protecting trees from becoming infested.

If a tree is already infested, pesticide treatments will not prevent the beetles from emerging and infesting other trees. Tree owners should not attempt to save an infested tree with pesticide injections. While there are pesticides on the market labeled for such purpose there are few published reports that indicate any success and a number of reports that show failure, either to save infested tree or protect a tree from becoming infested.

Dr Ball also states that generally, it is more effective for homeowners to hire a commercial applicator with the experience and equipment to properly treat and protect the trees. Homeowners considering treating their own trees are cautioned to use the proper equipment and only apply pesticides that are labeled for this purpose. Homeowners may not treat trees that are not on their property unless they are a South Dakota certified applicator.
