About this file
This is a Herbicide Standards attachment document issued by the Missouri Department of Conservation establishing requirements for pesticide application services related to post-harvest timber stand improvement work at Pea Ridge Conservation Area, Compartment #08 in Washington County, Missouri. The project encompasses five timber stands totaling approximately 58 acres across Stands 44, 51, 52, 53, and 66. Contractors must possess a valid Commercial Certified Pesticide Applicator license from the state of Missouri and comply with all provisions of the Missouri Pesticide Use Act. The scope of work requires herbicide application to tree stumps and girdled trees using two primary treatment methods: cut stump treatment for stumps of any size and girdle (frill) treatment for stems nine inches or greater in diameter. Acceptable herbicides include triclopyr ester, picloram, and 2,4-D solution, and all applications must follow label directions precisely. The Missouri Department of Conservation will conduct periodic inspections to verify compliance with established standards.
Herbicide applications must incorporate specific operational requirements, including the mandatory addition of a noticeable dye to herbicide solutions for spot-checking verification. Cut stump applications must be completed within one hour of cutting and applied only to the cambium layer using a flow rate regulator for consistent coverage. All herbicide applications must target only specified tree species—sugar maple, red maple, elm, black gum, and Carolina buckthorn—with application suitable year-round except during periods of sap flow. Contractors are prohibited from applying herbicides to non-target species or areas. Documentation of compliance with licensing requirements must be provided to the Department upon request. No pricing terms, set asides, funding amounts, or contract duration information is specified in this standards document.

ATTACHMENT 1
MISSOURI DEPARTMENT OF CONSERVATION
RECOMMENDED HERBICIDE STANDARDS
The contractor must abide by rules and regulations set forth in the Missouri Pesticide Use Act. The contractor must show proof of being a Commercial Certified Pesticide Applicator in the state of Missouri.
All herbicide application methods including solution ingredients and measurements must be consistent with the label for the chosen herbicide. All herbicide applications requiring cutting must be made within one hour of cutting the stem. Application of herbicides to non-target species or areas is prohibited.
A noticeable dye must be mixed into the herbicide solution to allow for spot checking by the Missouri Department of Conservation. A department representative will periodically inspect work performed to ensure that all treatments have been conducted according to the standards set forth in this contract.
Use of herbicides is required on any girdled trees and on the stump of the following selected tree species: Herbicide shall be applied to the stumps of any sugar maple, red maple, elm, black gum, and Carolina buckthorn stems that are cut.
The following application methods and standards are to be used under this contract (check all that apply):
Cut Stump Treatment – for tree stumps of any size, apply with a spray nozzle or squirt bottle directly to the cambium layer of the exposed stem. It is not necessary to apply to the center or heartwood of the stump. The use of a flow rate regulator is required to ensure adequate and consistent coverage. Year-round application is suitable except during periods of sap flow for the target species.
Acceptable Herbicides: triclopyr ester, picloram & 2,4-D solution
Girdle (Frill) Treatment – for stems 9 inches in diameter or greater in size, use chainsaw or similar cutting tool to make cuts into the stem of the tree at a convenient height completely encircling the trunk. The cutting depth should expose the cambium portion of the stem so that the herbicide will be readily absorbed. Apply the herbicide to the cut girdle. See chosen herbicide label for directions on amount of herbicide to apply to girdle as they can vary by product. Application is year-round except during periods of sap flow for the target species.
Acceptable Herbicides: triclopyr ester, picloram & 2,4-D solution
