On September 6, DuPont began a process to fairly resolve claims for impact on trees that DuPont™ Imprelis® herbicide may have caused. Below are links to documents useful to turf professionals who applied Imprelis® last fall or this spring. More information is available at http://www.imprelis-facts.com/ and at (866) 796-4783. The deadline for submission of claims is November 30, 2011.
Note on fall fertilization: Fertilizing affected trees and shrubs during 2011 is not recommended, but fertilization of the turf in the fall of 2011 is recommended per normal turf fertilizer recommendations (see recent turf tips on September 1, 2011). When damaged trees and shrubs are surrounded by turf, take care to fertilize outside the drip line of damaged trees so not to stimulate new growth of the trees.
