In June 2011 the Minnesota Department of Agriculture (MDA) began receiving reports that a new herbicide, registered by DuPont under the trade name Imprelis (active ingredient: aminocyclopyrachior), may be linked to non-target plant injury. In order to better understand the situation possibly linked to use of Imprelis in Minnesota the MDA sent out a letter on June 27, 2011 to all licensed pesticide managers asking them to fill out and return an anonymous online survey by July 11. The purpose of the informal survey was not to receive statistically valid information, but rather to quickly gather information. Note: This nonstatistical, anonymous survey was conducted early in July as the issue was unfolding and does not represent anything more than a snapshot in time.
Approximately how many properties have received an Imprelis application?(106 participants responded; of the 106 respondents, 26 had applied Imprelis)
Of those properties that received an Imprelis application, how many have signs or symptoms of non-target plant injury?
On properties where you have observed non-target plant injury possibly associated with an Imprelis application, how many have the following injuries:
Dieback of tissue on new growth on conifers
Death of conifers
Curling, stunting of deciduous trees
Death of deciduous trees
Curling, stunting of ornamental plants
Death of ornamental plants
In general how concerned are you about this issue?
Not At All
Do you plan to use Imprelis in future pesticide applications?
