[[821.4 Pesticides and the Environment\|'''Pesticides''']] are in a broad category including insecticides, herbicides, algicides, miticides and several other chemicals specific to a particular target. Insecticides are chemicals used to control insects.

	'''Herbicides''' are chemicals designed to control plant growth. When [[821.10 Equipment and Application Methods\|applied]] at the correct rate, proper time and method, with the [[821.10 Equipment and Application Methods\|proper equipment]] in suitable weather conditions, herbicides accomplish their manufacturer’s claims. MoDOT recognizes herbicides as a vegetation management ~~tool no different from other tools such~~ as lawn ~~mowers~~ or brush ~~hogs~~. The word “chemical” often raises a red flag with [[821.3 Public Relations\|the public]]. Some express great concern about applying a synthetic chemical to control a [[821.18 Noxious Weeds\|noxious weed]] yet ~~do not hesitate to have~~ a synthetic chemical ~~injected~~ into ~~their~~ own ~~body~~ to control diseases. Medicine is used to control and prevent disease, herbicides are used to control and [[821.16 Total Vegetation Control Treatment\|prevent vegetation]]. Both can create disastrous results if not used correctly, but when used correctly, can improve the quality of life.		'''Herbicides''' are chemicals designed to control plant growth. When [[821.10 Equipment and Application Methods\|applied]] at the correct rate, proper time and method, with the [[821.10 Equipment and Application Methods\|proper equipment]] in suitable weather conditions, herbicides accomplish their manufacturer’s claims. MoDOT recognizes herbicides as one of the tools used in vegetation management, the same as a lawn mower or brush hog. This is referred to as Integrated Vegetation Management or IVM. It is a practice of site evaluation and using the best resources you have available to maintain the desired vegetation management. Within IVM programs, herbicides are judiciously applied in a focused, selective manner. Herbicides are used to eliminate invasive plants proven difficult to manage by hand or mechanical maintenance methods. The word “chemical” often raises a red flag with [[821.3 Public Relations\|the public]]. Some express great concern about applying a synthetic chemical to control a [[821.18 Noxious Weeds\|noxious weed]] yet we introduce a synthetic chemical into our own bodies to control diseases in the form of medications. Medicine is used to control and prevent disease; herbicides are used to control and [[821.16 Total Vegetation Control Treatment\|prevent vegetation]]. Both can create disastrous results if not used correctly, but when used correctly, can improve the quality of life.

	The purpose of this article is to ensure we use herbicides correctly along Missouri roadsides. MoDOT has guidelines for the [[821.7 Planning and Ordering\|planning and ordering]] of herbicides as well as their [[821.5 Storage Facilities\|storage]] and [[821.6 Inventory Control and Storage\|inventory control]].

	This article takes information from the manufacturer's label on each herbicide and applies it to uses on highway right of way. Operators and their supervisors must read and follow the label.		This article takes information from the manufacturer's label on each herbicide and applies it to uses on highway right of way. Operators and their supervisors must read and follow the label. The label is the law.

	The rates listed in this article are recommended rates for Missouri roadsides. The label will list a wide range of rates since the manufacturer must consider all parts of the country with a broad range of soil and seasonal conditions. Rates listed here are what have been successfully used in Missouri with the concurrence of the manufacturer's representative.

	MoDOT is very concerned about the safe use of herbicides for the operator, the public and the environment, both on and off the right of way. This is why we do not use or purchase restricted use herbicides (or ~~RUP~~, restricted use products). We encourage employees to attend training sessions offered each year by MoDOT. Employees are also encouraged to obtain and maintain a Certified Public Operators License offered each year in cooperation with MoDOT and the Department of Agriculture.

This is why we do not use or purchase restricted use herbicides (or RUPs, restricted use products). We encourage employees to attend training sessions offered each year by MoDOT. Employees are also encouraged to obtain and maintain a Certified Public Operators License offered each year in cooperation with MoDOT and the Department of Agriculture. This license is for the application of pesticides on the rights of way if employed and doing the work for a public agency such as MoDOT.

This equipment must be used when required. Unnecessary use of safety equipment is discouraged due to the possibility of heat-related problems.

	Protect yourself from splashes or [[821.14 Herbicide Spills Incident Reporting\|spills]] during mixing. To reduce exposure to herbicides, use common sense and personal hygiene practices such as washing hands, arms and face frequently, changing clothing daily, not walking in areas treated when still wet and monitoring the wind direction and speed~~. Wash~~ clothing separately at home and use care when climbing on truck or sprayer because of wet surfaces. It is highly recommended to keep a separate tank of clean water on the spray truck to flush immediately if a spill occurs.

	[http://wwwi/maintenance/ Maintenance] purchases herbicides annually for the entire state based on quantity requests submitted in the fall by the districts. When new herbicides are received, the previous year's stock is to be placed where it will be used first. This is referred to as "First In First Out" (FIFO). District maintenance is to be notified if there is an oversupply of one or more herbicides.

	Operators and supervisors should know the visual effects of the herbicides used by MoDOT. Some herbicides such as 2,4-D, may have a noticeable effect within hours under certain weather conditions. Others may take days, weeks, or in the case of Krenite S, as much as nine months for the results to be visible. This article also contains guidelines for special conditions such as those for [[821.19 Problem Weeds\|problem weeds]], [[821.20 Woody Plant Control\|woody plants]], [[821.21 Aquatic Areas\|aquatic areas]] and [[821.22 Weed Control in Landscaped Areas\|landscaped areas]].
