Optrol by Plant Care Science Shows Promise in Protecting Ash Trees
Tens of millions of ash trees are being killed by emerald ash borers, a flat headed borer with no natural predators in the United States. Few insecticides have been effective in controlling this attack””at least, until now.

Research in Toledo, Ohio shows Optrolâ„¢, a concentrated 21.4% imidacloprid formula developed by PlantCare Science, has proven effective in protecting ash trees from emerald ash borer, according to studies by Ohio and Michigan State Universities. Dan Herms, an Entomologist at Ohio State University, says, “Optrolâ„¢ soil drenches provided the most consistent control of Emerald ash borer. We recommend Optrolâ„¢ when a home owner is treating trees larger than 10 inch diameter themselves.”
What is the Emerald Ash Borer?
Emerald ash borer (EAB) is an invasive wood boring beetle from South East Asia that is predicted to infest all unprotected ash trees in the United States and Canada over the next 20 years. EAB has spread very quickly since it was found in Michigan in 2001, it has spread throughout the upper Midwest as far east as New York and as far west as Iowa.
Biology of the Beetle and Ash Tree
Emerald ash borer lays its eggs on the bark of an ash tree and the larvae tunnel through the bark and begins consuming the sapwood of the tree. This feeding disrupts water flow to the canopy dehydrating and killing that portion of the tree.
Symptoms of Emerald Ash Borer?
Early infestations of emerald ash borer are nearly impossible to detect ; the tree does not show outward symptoms. However as the infestation grows, the tree will decline and die.
What you will see as the infestation progresses:
- D shaped exit holes
- Early fall coloration
- Dieback of branches with sparse foliage
- New branches sprouting from the lower trunk
- Woodpeckers feeding on infested trees
- Decline in groups of ash all at the same time
Advantages to Using Optrolâ„¢
- Fast and easy to apply, just measure, mix, pour
- Available to homeowners, whose only resources until now have been to cut down their trees or use an ineffective products
- The only Do It Your-self emerald ash borer treatment that has been effective with trees that are 10″ or more in diameter. (One 8-ounce bottle will protect up to a 64″ circumference)
- Affectively protects trees, shrubs and flowers against Japanese beetles, aphids and many more garden pests
Optrolâ„¢, is a preventative method of controlling Emerald ash borer. One application provides 12 months of control. Experts recommend beginning treatment when borers have been found within 15 miles of a person’s property, no matter the season (as long as the ground is not frozen or over saturated.) Optrolâ„¢ is not harmful to the environment when used according to the EPA label instructions.
