North Farm
Address: 1925 Research Farm Rd. Lexington, KY 40511
Details provided by Matt Peake
Each program typically handles its own pesticide applications, making this a multi-user facility.
Smaller, more frequent applications are common compared to larger applications on commercial farms.
Heavy use of pesticides occurs in the spring (mid-April to end of June), with continued use into the summer and fall.
Estimated pesticide loading rates:
Peak use period (spring): 25 to 50 gallons per day.
Other months: 10 to 15 gallons per day.
Significant sprayer clean-out is required due to the frequent, smaller applications.
A holding area for rinsate may be needed on high-usage days when more rinsate is generated than the system can handle.
Princeton Research Farm

Details provided by Travis Legleiter
Peak usage periods:
Spray bay: Peak in May to July; used from March through November.
Prep room: Peak in May to August; some usage from February to December.
Estimated rinsate generation for the growing season (March to November):
Approximately 2,000 gallons of rinsate.
The biobed needs to handle up to 3,000 gallons of rinsate.
Pesticide diversity:
The UKREC has 445 different trade name products, with 100-150 different active ingredients.
Weed Science program used 38 active ingredients in 2023; lists of active ingredients from other programs are being gathered.
Future use of experimental pesticides and new active ingredients will likely alter the products used and contained in the rinsate tanks.
UKREC Crop Protection Bldg PLAN 111323.pdfDraft of the Crop Protection Complex created by UKREC's in-house team that has been given to the architects.
Crop Protection Complex is being designed which will be producing the rinsate that will need to be handled by the biobed.
The facility is divided into three sections:
Spray bay: Handles large sprayers like the Case IH Patriot 3240 (800-gal tank) and smaller sprayers (20 to 250-gal tanks). Peak use is from May to July, with 8-10 sprayer cleanouts per week.
Prep room: Used for mixing herbicides, insecticides, and fungicides in smaller amounts (2 liters to 3 gallons). Creates rinsate from cleaning measuring vials and triple rinsing containers.
Both the spray bay and prep room drain to sump tanks, which pump rinsate into two 1,500-gallon storage tanks (total 3,000 gallons).
Additional facility design details:
The biobed system should handle peak rinsate volumes between mid-April and mid-October.
Storage tanks are at a higher grade to allow gravity feeding into the biobeds.
An anti-frost system is being considered for one of the tanks to handle rinsate from late fall and early spring applications.
The top 15 of this list would accurately reflect the majority of herbicides being applied by the large Case IH sprayer and research ATV and tractor sprayers that will create the majority of rinsate needing to be handled by the biobed.
Glyphosate and glufosinate are the most commonly applied herbicides by the Case IH sprayer and other sprayers.
