Chemical control means the application of pesticides, include microbial pesticides such as Bacillus thuringensis var. israelensis or growth regulators such as methoprene, to the environment for the purpose of preventing, reducing or eliminating aquatic (immature) or adult mosquito populations. Under §1.5(A) of this Part for Conducting Mosquito Control Programs, chemical control of mosquitoes by a Mosquito Abatement District is restricted to application of pesticides that are listed in the Mosquito Abatement Board List of Allowed Pesticides. Equipment - Any apparatus, tool, provision or necessity purchased with Mosquito Abatement Grant funds to conduct the approved project or activity.

Chemical control means the application of a herbicide (weed killer) in strict accordance with the directions on the product and the regulations of the Code of Iowa and the Iowa Administrative Code, as amended.

More Definitions of Chemical control

Chemical control. When employed in conjunction with prescribed burning and mechanical control, the judicious use of herbicides can be an important component of management programs for controlling weeds. Some weeds such as purple loosestrife, buckthorn (Rhamnus spp.) and honeysuckle (Lonicera spp.), ▇▇▇▇ canarygrass, common ▇▇▇▇, sandbar willow, and cattails are controlled more effectively by chemical treatment than by most mechanical control measures. For aggressive weeds, an appropriate herbicide will be applied. Because of the potential for damage to native plant communities, the use of preventative herbicides will be limited to problem areas and problem species for which manual control is ineffective. Aquatic herbicides will not be used to treat algal blooms. Glyphosate herbicide (trade names Rodeo or Roundup) is often recommended for use in naturalized landscape areas. Other herbicides such as Transline, Plateau, and ▇▇▇▇▇▇ are also used. The application of herbicides will be performed only by persons licensed or certified in the State of Illinois for pesticide/herbicide application. Herbicide use will be in strict compliance with all application rates, procedures, warning labels and applicable codes, standards and best management practices. Generally, wick application will be preferred over spray application, which is less selective. Wicking applies herbicide only to individual plants, typically using hand application or pipe dispersal methods. The handwicking or “glove of death” method for specifically targeting weedy plants while protecting higher quality plants in sensitive habitats. Pipe dispersal methods are also appropriate for targeting weedy plants while avoiding desirable plants growing alongside them by using a canvas-covered, perforated, chemical filled PVC pipe. Trained personnel walk the area, swinging pipe (commonly 8-feet long) from side to side above the native plants but deliberately striking invasive species. The pipe strikes and bends the weeds, smearing them with the chemical and destroying them within a few days. If used, spray applications will not occur on gusty days because non-target species could be affected.

Chemical control means using conventional or natural herbicides to eliminate noxious weeds or additional invasive, non-native plant species that present a special concern within a specified area. It does not mean treatments for general vegetation management.
