There are two state pesticide laws in Indiana. These are the Indiana Pesticide Registration Law (IC 15-16-4) and the Indiana Pesticide Use and Application Law (IC 15-16-5). In addition, there are a number of rules that have been developed under those two laws to further define regulatory requirements. You can view the laws in their entirety in this section.
