Abstract: Embodiments of the present invention are directed to a fluid dispenser for dispensing landscape maintenance fluids or the like which contain products such as fertilizers, herbicides, and pesticides. The fluid dispenser injects the fluids directly into the mainstream of an irrigation system. The dispensing system operates by shunting a portion of the main irrigation water stream through a bypass to the dispenser containing the product to be dispensed. The water dilutes the product to be applied, and is injected back into the main irrigation stream by the back pressure of the irrigation system. When the irrigation is completed, the fluid flow in the main irrigation stream is reduced or terminated and the pressure drops. After the pressure drops, the fluid ceases to be diverted to the container, and the main irrigation stream drains. The vent opens, and the atmospheric pressure and the configuration of the filled outlet channel cause a siphon action to continue drawing fluid from the container into the main irrigation stream. This siphoning of the fluid from the container continues until the container is empty.
