Imprelis possibly killing trees and shrubs
Posted from our Reliable News email publication
Not good
Imprelis, a new weed killer from DuPont, went on the market this year (after significant testing) and is possibly killing trees and shrubs across the country.
Reliable Property Services does not use Imprelis.
Do not think ill of your lawn care vendor - unless we find damage is due to improper application - this could happen to any company. Imprelis was thoroughly tested and should have been safe for commercial use. Click below for video - a touch sensational - from KSTP in the Twin Cities. Story continues below video.
Here's what's happening
Imprelis is only available to licensed, commercial applicators as a broadleaf weed killer (clover, dandelions, creeping charlie, etc.) and by all accounts is doing a great job killing the weeds. It appears that trees throughout the country are taking the herbicide up through their roots and killing new growth, branches and entire trees.
There is very little known about the possible Imprelis damage right now. Dupont - the maker of Imprelis - is cautiously investigating but taking no responsibility. Many chemical distributors have stopped selling Imprelis. One of those distributors is Reinders. I spoke with their Joe Churchill this afternoon. He is hearing of multiple cases of damage in the Twin Cities. He says that Imprelis has a 90 day residual (stays active in the soil for 90 days) and we are just in the first two weeks of learning what is going on with Imprelis.
What property managers can do
Sorry, not a whole lot. Hopefully trees that only have damage to new growth will grow out of it but this is a very new problem and little is known. Speak to your lawn care vendor and request MSDS (Material Safety Data Sheets) sheets for all chemicals being used on your properties. They are required to have them available for you (here are ours). Right now, there is no known course of action and we do not know how to minimize the damage of Imprelis.
