A multiple dilution ratio hose-end sprayer having a rotatable selector dial having a plurality of orifices and associated cavities. The orifices are adapted to intersect a fluid passageway extending from a fluid container to a mixing chamber used for mixing selected amounts of fluid from the container with water entering the mixing chamber. Water is supplied to the mixing chamber through a first and second spaced apart nozzles, an annular channel extending from between said nozzles to an intersecting channel adapted to communicate with a cavity associated with an orifice intersecting said fluid passageway. The nozzle opening from said second nozzle being smaller than the discharge opening for the sprayer, but preferably equal to or smaller than opening from the first nozzle.

In a multiple dilution ratio hose-end sprayer having a mixing head containing a mixing chamber which includes a sprayer discharge outlet, a means for connecting a water source to said mixing head for supplying water to said mixing chamber, a means for securing a fluid container to said mixing head, passage means for conveying fluid from said container to said chamber and control means for varying the flow of fluid from said container to said chamber, the improvement therein comprising: a. said mixing chamber being in fluid communication with a fluid inlet means smaller than the sprayer discharge outlet; b. a rotable control dial having a plurality of orifices and associated cavities, said dial being rotably mounted adjacent said mixing head, said orifices and cavities being positioned on circles concentric with the axis of the dial which intersects the axis of fluid passage means for fluid communication between a selected orifice and said passage means, said cavities being positioned on the surface of the dial adjacent to the mixing head and in communication with said associated orifice; c. retainer means for biasing said rotatable dial against said mixing means and indexing a selected orifice in communication with said passage means; d. retainer biasing means; and e. an intersecting channel extending from ahead of said mixing chamber to communicate with the cavity of the associated orifice indexed in communication with said passage means.
