1 , <br /> BASIC CHEMICAL CONTROL GUIDELINES: The first rule of herbicide use is to read the label <br /> before using the product and follow all directions and precautions.The label is the law. Seek <br /> assistance before purchasing or using an herbicide if not absolutely sure of the use or purpose of <br /> the product. Chemicals are powerful tools that should be used judiciously. Follow all instructions <br /> (application rates, proper safety equipment,appropriate weather conditions, etc.) as directed <br /> on the herbicide's label. Safety precaution may include safety glasses, rubber gloves, long- <br /> sleeved shirts, long pants, high-top shoes, and socks are common sense precautions.An <br /> additional precaution includes the use a respirator to protect sensitive mucus membranes in <br /> nose and throat. Follow proper clean-up and disposal procedures for the equipment and <br /> containers. <br /> Care must be taken to avoid spraying herbicides near water unless they are specifically labeled <br /> for aquatic use. An aquatic-approved herbicide is required when applications will be made over <br /> water or come in contact with surface water. An aquatic-safe herbicide is a great quality to have <br /> in an herbicide when applying near any kind of stream or river(riparian areas)or drainages. <br /> Broadleaf selective herbicides can either be applied by spot spraying individual plants or by a <br /> continuous spray over an entire area.A non-selective herbicide (such as glyphosate) should only <br /> be used if spot spraying.Avoid using soil-active herbicides (such as dicamba) near windbreak <br /> plants or other desirable woody vegetation. Plant injury or death can occur.Also, do not allow <br /> any herbicide to drift onto desirable vegetation for the same reasons. From time to time, if <br /> possible, alternate the herbicide (active ingredient) applied to the noxious weed infestation.This <br /> will help to prevent the weeds from developing chemical resistance. <br /> When using a foliar spray, be sure to get good spray coverage of the plants.All of the leaves <br /> should have herbicide contact.The sprayed plants should be obviously wet, but not dripping <br /> with herbicide. If a surfactant is indicated the herbicide label, it should be mixed as directed with <br /> the herbicide. Surfactants help herbicides do their job by reducing the surface tension of liquids <br /> between two liquids or a solid leaf. Calibrate the sprayer to the recommended application rate. <br /> Chemical sources in the Pueblo area include agriculture coops and agriculture retailers such as <br /> Big R and American Fertilizer Company in Pueblo. Herbicide spraying subcontractors in the area <br /> include Chem-Way and Colorado Vegetation Management. <br /> BASIC MECHANICAL CONTROL GUIDELINES: Clean the mowing equipment to remove seeds and <br /> vegetative plant parts with a pressure washer before and after mowing operations.This is <br /> especially important when mowing flowering plants.To limit any spreading of weeds, do not <br /> clean equipment in un-infested areas or near roadways or streams. <br /> Some flowering plants and their cut-off flower heads can still develop viable seeds. If the plants <br /> have already bloomed when you cut or pull them, it is important to properly dispose of them. <br /> Put them in a garbage bag, make sure bags are securely closed, and send them to a landfill. <br /> Generally, it is okay to mow one week after spraying. Mowing should not be done immediately <br /> following applications to allow the sprayed plants time to absorb the herbicide into their <br /> systems <br /> BIOLOGICAL CONTROL GUIDELINES: Biological controls or insects are a good option for larger <br /> infestations. Once established, insects tend to persist and provide control for many years. <br /> Biocontrol agents are affected by the environment and climatic/cultural conditions. Information <br />
