Herbicide. All areas to receive planting, other than native seeded areas, shall be treated with a pre- emergent herbicide prior to planting. Pre-emergent herbicide treatments used shall not be detrimental to the intended replacement plantings. The application of herbicide shall follow the Department’s standards, Recurring Special Provisions 624-M-024, and the manufacturer’s recommendations. In addition, the application of the pre-emergent herbicide shall be in compliance with the Noxious Weed Control Plan. Developer shall treat any perennial weed species with a post-emergent non-selective herbicide not less than two weeks prior to beginning soil preparation activities. Perennial weed treatment shall be as per the Department’s standards and in accordance with the approved Noxious Weed Control Plan.
Herbicide. A. Post Emergent Herbicide: Roundup (Glyphosate) as manufactured by Monsanto Company or approved equal.
Herbicide. Carefully controlled applications of foliar herbicide dissipate quickly in the environment when used appropriately. Use of herbicides in Minneapolis parks should only be used when other options are not feasible and must be undertaken in consultation with MPRB in keeping with their Integrated Pest Management (IPM) plan. Often non-native vegetation is spot sprayed with herbicide after it regrows following a disturbance such as fire. The ideal time for herbicide application is when vegetation has reached 4” – 6” in height, but before it goes to seed. Herbicide treatment may need to repeated multiple times on a selective basis. In addition to disturbances designed to remove existing vegetation, tactics such as aeration and thatch removal may be helpful in allowing seeds to make contact with and become incorporated into the soil layer. A drag that is light enough not to compact the soil such as a lightweight cultipacker or piece of chain link fence can also help work seeds into the soil. to help species establish that might be less likely to successful germinate and spread from seed alone. Because tall prairie grasses can take over if planted as part of initial restoration, we recommend planting tall grasses as plugs later in restoration phases in key locations as desired once species planted by seed have become established.
Herbicide. A foliar herbicide could be spot sprayed on problem species in consultation with MPRB in accordance with their IPM plan.
Herbicide a. For various weeds and broadleaf growths, herbicide treatments will apply a 41% glyphosate material at a 3% solution applied at least two (2) weeks prior to cutting.
b. For various vines and woody plants, herbicide treatments will apply a 40% Triclopyr material at a 2% solution applied at least three (3) weeks prior to cutting.
Herbicide. The herbicide used will be Aquathol K (dipotassium salt of endothall) at a minimum concentration of 1.0 parts per million (ppm) in areas with a water depth of less than 6-feet and a maximum concentration of 1.5 parts per million (ppm) concentrations in areas of over 6-foot depth of water.
Herbicide. Herbiciding constitutes pre-emergent and post-emergent treatment of undesirable grass, weeds, vegetation and plant material growing in, along and around landscape areas with an approved herbicide to maintain these areas in an attractive and manicured condition. Herbicide use shall be limited to specific sites or undesirable growth in the landscape areas identified by the Contractor and authorized by the County’s Contract Coordinator. The Contractor shall keep all planted areas free of weeds. Weeds in the landscape (turf and ornamentals) shall be controlled by mechanical removal and /or with pre-emergent and post-emergent herbicides. Herbicides shall not be applied when there is a danger of winds that could cause spray drift and damage to surrounding landscape areas. During each mowing cycle, the Contractor will be required to remove and dispose of all vegetation including but not limited to vines, seedlings, weeds and sucker growth from shrubs, trees and plants that have grown on, within, around, through or on top of all trees, shrubs and plants. The non-selective post-emergent herbicides used shall be a County approved equivalent applied in conformance with the manufacturer's instructions. The application of pre-emergent herbicide should be considered and incorporated into the schedule. Selective herbicides shall be approved by the County’s Contract Coordinator. The cost of all work and materials for herbiciding shall be in the unit price bid for Landscape Bed Maintenance. Note: Herbicides shall not be used as a substitute for planter bed edging.
Herbicide. Is to be used for spot spraying of expansion joints of curb gutters, sidewalks and Curb Inlets. Herbicide along walls and fence lines will be permitted. The Contractors herbicide will require approval by the County’s Contract Coordinator for use. The Rate of Herbicide that is applied is to comply with the manufacturer’s label. Herbicide shall not be used as a replacement for weed- eating, edging or in areas susceptible to erosion.
