Request for Quote: Selective spraying of Teasel Species at Wildlife Areas in Northern Ohio

History and Overview

The ODNR, Division of Wildlife is seeking contractors to help control teasel on wildlife areas throughout Hancock, Wood, Sandusky, and Wyandot counties within Northwest Ohio (figure 1) through selective herbicide applications during

November and December 2025 and again in mid-May – mid-June of 2026. These areas consist of existing herbaceous upland fields with briars, shrubs, and tree seedlings in need of selective treatment of teasel.

Using dormant-season broadcast treatments of broadleaf selective herbicide (e.g. Grazon Next HL; EPA Reg. No. 62719-

628) in early November allows for a more selective management technique that favors most native plant species, as many native forbs are top-killed by frost this time of year while teasel rosettes are green. It also makes sense to use dormant-season broadcast applications in areas that are difficult to spray and avoid native vegetation during the growing season. These are sites that have teasel surrounded by native, susceptible plant species. This dormant-season application of Grazon Next HL will be focused on growing rosettes of teasel spp. This residual herbicide could also effectively kill two generations of rosettes, both existing rosettes at the time of application and future rosettes that would germinate and grow within the following 3 to 4 months. These dormant season broadcast treatments will be followed up by spot treatments within these areas during early summer with a low-rate application of Milestone herbicide (EPA Reg. No. 62719-519) to assure any remaining plants are treated selectively within application areas.

Methodology and Timeframe for application of Grazon Next HL and Milestone Herbicides

This request for quote will be for the broadcast treatment of Grazon Next HL targeting rosettes of teasel species in

November and December of 2025. Given ideal weather conditions, contractors may start work after the 21st of October at the earliest to avoid damage to native forbs. The weather conditions should be the key to application timing, where applications should only be done after two hard frosts (below 30 degrees Ferenheit) have occurred. The weather should be sunny or a warmer than average day (minimum of 40 degrees Fahrenheit) with no precipitation. The broadcast treatments should be applied just above the low rate listed on the label for teasel species and may be conducted via spray boom, boomless nozzle application, aerial (drone, rotary wing, etc.) techniques, ATV/UTV-mounted sprayer, or hand equipment as needed.

The contractor should select the ideal techniques to maximize coverage and control of invasive vegetation in mapped areas. Some fields may need bushogging due to existing tall vegetation prior to application of herbicides if contractor doesn’t have access to a boomless nozzle or drone. Tall herbaceous vegetation and interspersed woody vegetation exists at some sites that will impede travel with a boom sprayer. Other fields may have sparse tall vegetation that can be handled with a boomless sprayer or aerial/drone equipment, and mowing may not be required. This will be left to the option of the contractor. A contractor determination on the need for complete mowing or spot-mowing fields prior to boom spraying vs. utilizing alternative boomless or aerial spray techniques should be completed during the site visit prior to bidding to assure that the proper technique is utilized to get complete coverage of mapped areas. No application of Grazon Next HL shall be allowed after December 24th, 2025 due to negative residual affects on emerging forbs during the following early spring.

Follow-up spot-treatments application of Milestone herbicide must be done on bolting teasel after May 15th and before

June 15th, 2025, at just above the low rate listed on the label for teasel. Touch-up applications of Milestone herbicide may most easily be done in late May or early June when teasel is taller and most recognizable. There may be a need for multiple touch-up applications. Again, the contractor should determine the best techniques for spot applications, whether utilizing ATV or UTV sprayers, aerial techniques, or low-volume hand equipment to spot treat all invasive vegetation within treatment areas. Mapped application areas will be evaluated by the project manager after June 15th, 2025 and any areas that have a greater than 5% presence of teasel on an acre-for-acre basis will be omitted from the acreage payment. The contractor will need to provide all herbicides and adjuvants.

Efforts need to be made by the contractor to avoid work during weekends in November and during any deer-gun seasons to avoid conflicts with property users. All work shall be conducted Monday through Friday unless prior approval is obtained from the ODNR, Division of Wildlife project manager. Ground disturbance must be kept to a minimum and equipment with low ground pressure, is encouraged but not required. The use of GPS-enabled phone or other equipment is recommended for this project but not required. An electronic KML file for Google Earth Pro or another phone app is available upon request.

All work will need to be completed by June 15th, 2025. Extensions for work may be granted at the discretion of the project manager but are not likely. The contractor is required to contact the ODNR, Division of Wildlife project manager at least two business days prior to initially entering the property for work. The work sites are split into the following tasks and can be bid separately or omitted by contractors at their option. Contractors that bid on one or more tasks, need to assure they have the capacity to complete all work efficiently within slim weather windows during November, as weather conditions are volatile that time of year.

Task 1. Wyandot Wildlife Area (Wyandot County): The mapped application area is a herbaceous field with teasel. The

Wyandot County application area is approximately 7 acres and delineated in figure 2 and the attached KML.

Task 2. Hancock County Wildlife Areas: The mapped application areas cover old fields with sparse and thick teasel.

Most woody vegetation is less than 6 feet tall but there are scattered trees and shrubs present in both areas. Hancock

County application areas are approximately 45 acres or more and delineated in figures 3 and 4, in addition to the attached KML.

Task 3. Wood County Wildlife Area: The mapped application area is comprised of a newly restored field that has been top mowed and vegetation is less than two feet tall. This application area is approximately 41 acres and delineated in figure 5 along with the attached KML.

Task 4. Sandusky County Wildlife Areas: The mapped application areas cover the recently restored fields with herbaceous vegetation. In total, these application areas are approximately 62 acres and delineated in figure 6 and 7, along with the attached KML.

Guidelines for submitting a quote (deadline August 28th, 2025):

A site visit is required prior to bidding. Contractors must reach out (call or text) to the project manager during their site visit to communicate any thoughts or questions. The call will be documented that the contractor was on site, once questions are answered form both parties. Bidders without documentation of a site visit will be disqualified. Please submit a quote by August 28th, 2025 in Ohio|Buys. The vendor will not receive payment until all products and services have been received as per the above specifications and deadlines listed in this document. If the successful bidder does not complete the work as specified above or exhibit work progress during ideal weather conditions the ODNR, Division of Wildlife reserves the right to pro-rate the payment or cancel the purchase order. Thank you for your interest and please don’t hesitate to give me a call with any questions!
