CleanFARMS Collection Dates Released

cleanfarmsCleanFARMS will be offering its obsolete and unwanted pesticides collection campaign this fall.

This program allows farmers to bring in unwanted or obsolete agricultural pesticides, at no cost, to one of 27 collection sites for safe disposal at an approved waste management facility.

Note that these are single day programs, so you need to drop off at the assigned location on a specific day.  For more information, and specific drop-off dates, you can see the Clean Farms Program poster.

For Niagara area growers, note that drop-offs will be accepted at Vineland Growers Co-op Jordan Station location on September 27, 2019.

2018 Poinsettia Wrap Up: Whitefly and Pesticides

Bemisia 4_SJAs suspected, it’s turned out to be a heck of year for Poinsettia.  Many growers faced Erwinia, others had rooting issues, and all faced significant pressure from Bemisia whitefly from infested cuttings.
