Chemical Control. Glyphosate (Roundup and Rodeo) has been used with some success on Ammophila, although its effectiveness is dependent on consistency and thoroughness. A label recommendation of 8% Rodeo plus 0.5 to 1.5%nonionic surfactant (spray-to-wet) was developed for Oregon, Washington, and California following trials by the California Department of Parks and Recreation, the Oregon Department of Fish and Wildlife, and the Monsanto Company. Rodeo, a form of glyphosate without surfactant, was preferred in Oregon because of concerns about groundwater contamination. Rodeo is approved for aquatic use because it lacks the polyethoxylated tallowarnine present in the surfactant in Roundup. The label also recommends wiper applications for selective control, using a 33% solution plus 1.0 to 2.5% nonionic surfactant and avoiding contact with desirable vegetation. For either method, plants should be treated during periods of active growth. The use of Roundup to control Ammophila was tested extensively by the California Department of Parks and Recreation and the University of California Davis at several California dune systems. Although results have not been published, the investigator reports good success using a 10% solution with added surfactant (0.5%) (Xxxxxxx, pers. comm.). Since these experiments were carried out, the surfactant in Roundup has been reformulated by Monsanto, which recommends no additional surfactant be added to Roundup-Pro or Roundup-Ultra (McColly, pers. comm.). Herbicides have been used on Ammophila most extensively at the Oregon Dunes National Recreation Area. In 1996-1997 about 60 acres of Ammophila were sprayed with an 8% solution of Rodeo (with surfactant) at Tahkenitch and Ten Mile dunes. In the first year only one application was used. Results were inconsistent, with some areas clearly missed. However, overall density and cover was significantly reduced (Xxxxxxx, pers. comm). In the second year (1997), missed areas were resprayed, and new areas were given two applications, but results are not yet available. Chemical treatment of Animophila is likely to be the most cost-effective method of those used to date. There are, however, problems with this method. Herbicides have biological impacts and may be politically California Exotic Pest Plant Council 1997 Symposium Proceedings unacceptable in a given area or for a particular agency (for example, the Bureau of Land Management is under an injunction prohibiting the use of herbicides on non-noxious weeds).

Chemical Control. Contractor shall comply with all rules and regulations of the Department of Food and Agriculture, the State Department of Health Services, and all other agencies which govern the use and application of chemicals required in the performance of the work to be provided pursuant to this Agreement. The term “chemicals” shall include but not limited to; fertilizers, herbicides, insecticides, fungicides, rodenticides, germicides, nematicides, bactericides, inhibitors, fumigants, defoliants, desiccants, soil sterilants and repellants. Contractor shall apply spray chemicals when air currents are still, preventing drifting onto adjoining property whether they are in, or near, the project. The Contractor shall submit a list of all chemical fertilizers, herbicides or pesticides proposed for use under this contract for approval by the Parks Supervisor. Contractor shall submit a schedule to the Contract Officer outlining date, location, and chemical type/analysis to be performed at least fifteen (15) days prior to the week of work. Said schedule must be approved by the Contract Officer before the work is undertaken. A pollution prevention plan shall be developed within the first sixty (60) days of execution of this Agreement to maintain compliance with industry best management practices for pollution prevention.
Chemical Control. Chemicals have been used by many natural resource professionals to achieve specific habitat management goals and objectives. Currently, many land managers use herbicides because of their effectiveness, ease of use and because herbicides can be relatively inexpensive. Although herbicide use may be an effective habitat management tool, a paucity of research exists on the effects of chemicals on reptiles and, specifically, to EMR. Therefore, it is strongly recommended that land managers consider specific biological factors and utilize a cautious approach when choosing an herbicide, application method, application rate, time of application, and time between applications. Due to the unknown impacts of herbicides to EMR, broadcast applications in Managed Land is prohibited except when land managers are re-establishing suitable habitat at highly degraded sites (e.g. converting row crops to native grasslands or to control monocultures of invasive species). Land managers may use other herbicide treatments such as spot spraying or wicking to control invasive plant species in Managed Land.
Chemical Control. Contractor shall comply with all rules and regulations of the Occupational Safety and Health Administration, and all other state or and local agencies which govern the use and application of chemicals required in the performance of the work to be provided pursuant to this Agreement. The term “chemicals” shall include but is not limited to; any solution, liquid, compound, or powder used for the purpose of cleaning, disinfecting, neutralizing odor, removing residues or gum, or removing paint on bathroom facilities and park amenities. The Contractor shall submit a list of all chemicals proposed for use under this contract for approval by the Parks Services Manager.
Chemical Control. No chemical controls on Commission Property are granted by this License.
