Winter Annual Weeds

Winter Annual Weeds

Four types of broadleaf weeds exist: 1) perennial (those living more than two years), biennial (those living two years), 3) summer annuals (those germinating in the spring and dying in the fall), and 4) winter annuals (those germinating in the fall and surviving the winter and dying the following spring). Since many of these winter annual weeds are now germinated, I thought it might be a useful exercise to review their identification. Below is one picture of various winter annual broadleaf weeds. Be on the lookout for these this fall and next spring.

Imprelis Return and Refund Program

Imprelis Return and Refund Program

On October 17, DuPont began a process to recall and refund Imprelis from Turf professionals. DuPont has contacted distributors, who will be coordinating with turf professionals to ensure that all remaining full and partially full bottles of Imprelis® are returned. Turf professionals have 10 business days to return all Imprelis® product (4.5 fl. oz., 1.0 gallon, and 2.5 gallon bottles) to them after the initial contact from the distributor. After returning the remaining Imprelis® to the distributor, turf professionals will be given either a refund or credits, depending on the distributor’s policy. In this EPA approved disposition plan, the EPA suggests that you maintain records associated with Imprelis®, including but not limited to: 1) quantities used and returned, including product lot numbers 2) application records, and 3) purchase records.

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.
