A mixing and dispensing sprayer apparatus is comprised of a bottle or container and a nozzle assembly where a fluid passed through the nozzle assembly mixes with a material contained in the container and the mixture of fluid and material then passes from the container back into the fluid flow through the nozzle assembly and exits the nozzle assembly as a spray. The container and nozzle assembly are molded as a single unit of a plastic material by a blow molding process. A hollow interior volume of the container communicates with a fluid conducting channel of the nozzle assembly through one or more ports formed in the apparatus. The nozzle assembly of the apparatus has an orifice formed therein that directs a portion of fluid flowing through the nozzle assembly into the container interior where the fluid is mixed with a material contained in the container, such as a particulate, liquid or soluble material, and the mixture of fluid and material then passes back through the port into the channel of the nozzle assembly where it is mixed with fluid passing through the channel and exits the nozzle assembly as a spray.
