TURKEY CREEK CD's NOXIOUS WEED CONTROL PROGRAM FOR PUEBLO COUNTY PAGE 3 OF 10 <br /> ❖ Saltcedar control is increased with cultural methods. Revegetation is very important in saltcedar <br /> control as the desirable plants will provide competition. After managing saltcedar infestations, <br /> oaiei desirable vegetation must be established(grass and forb seeding, cottonwood and/or <br /> willow cuttings)to prevent both the re-invasion of saltcedar and/or a secondary weed infestation <br /> in the newly exposed area. Also take into consideration when re-vegetating after saltcedar <br /> control that saltcedar increases the salinity of surface soil, rendering the soil inhospitable to <br /> many plant species. <br /> ❖ Saltcedar is best controlled with herbicides. For saltcedar control, spraying is most effective if <br /> done in the late summer to fall (mid-August to early October). However,herbicide applications <br /> on saltcedar can be accomplished at most times of the year with reasonable success (depending <br /> on method used and weather permitting). An appropriate surfactant mixed with the herbicide <br /> (refer to the label)will aid with the absorption of the herbicide into the plant and you will <br /> achieve better control results. <br /> ❖ An aquatic-safe approved herbicide, (such as Habitat)is a great quality to have in an herbicide <br /> when applying near any kind of riparian areas or drainages, as is common with most Saltcedar <br /> infestations. Care must be taken to avoid spraying herbicides near water unless they are <br /> specifically labeled for aquatic use. An aquatic-approved herbicide is required when <br /> applications will be made over water or come in contact with surface water. <br /> ❖ There are a number of types of treatments and application methods that can be used on <br /> saltcedar. The best method to use depends on the characteristics of the infestation itself. For <br /> large stands of saltcedar that are essentially monotypic,foliar applications are most effective. In <br /> areas where woody native plants are present and their continued existence is desired,it may be <br /> necessary to utilize a spot treatment method. <br /> • Foliar applications are those such as aerial applications done with a fixed-wing aircraft or <br /> helicopter or ground treatments done with a backpack sprayer or ATV. Aerial application is <br /> only recommended for areas that have little to no desirable shrubs and trees. When using <br /> ground equipment,it is possible to spray around native trees and shrubs such as cottonwood <br /> and willow,however, care must be taken to avoid damaging desirable plants. Foliar <br /> applications can be applied late spring to early fall. <br /> • The cut-stump method,a type of spot treatment,is to cut and treat saltcedar stumps with a <br /> herbicide. Saltcedar stems should be cut off within 2 inches of the ground's surface and <br /> immediately followed with a herbicide application to the perimeter edges of the cut-stems. <br /> The outer edges of the stems must be thoroughly sprayed or painted with the herbicide <br /> solution. This method is effective but note that the herbicide must be applied within 1 <br /> minute after cutting because wound healing occurs very quickly and decreases herbicide <br /> penetration(and therefore control). A tracer dye can be included in the herbicide solution to <br /> help ensure treatment of all individual stumps. Cut-stump application treatments can <br /> typically be done at any time except when snow is present. <br /> • Basal-bark application is a type of spot treatment method. This is done by spraying the <br /> lower 12 to 18 inches of the entire circumference of every stem, including the root collar, in <br /> such a manner that they become thoroughly wet but not to the point of runoff. Do not apply <br /> to bark that is wet from heavy dew or rain. Basal-bark treatments are most effective on <br /> stems smaller than 6 inches in diameter. A tracer dye can be included in the herbicide <br /> solution to help ensure treatment of all individual trees. Basal-bark application treatments <br /> can typically be done at any time except when snow is present. <br />
