A spray hood assembly for containing the spray mist of pesticides or other liquid agricultural chemicals in an application area as the pesticide or other liquid is applied to soil or vegetation. In a preferred embodiment, the spray hood assembly includes an elongated hood characterized by a selected number of arcuate hood segments attached to each other in end-to-end relationship and mounted on a trailer hitched to a tractor or other towing vehicle. As the suspended hood migrates over soil or vegetation, the pesticide or other liquid is sprayed into the hood. Air intake openings in the front of the hood segments permit entry of turbulent air which promotes mixing of the air and sprayed mist inside the hood and substantially uniform application of the mist to the soil or vegetation within the confines of the hood. In a preferred embodiment, a mist curtain extends downwardly from the curved front and rear panels of the adjacent hood segments for enhancing confinement of the mist in the hood during application.
