Abstract

A device for spraying pesticides and/or agricultural treatment chemicals has a housing configured to retain a spray canister, an actuator rod on the housing configured to contact an overcap attached to the canister, a shaft connected to the housing, and a linkage to reverse a triggering force so that the actuator pushes against the overcap. Attachments can be provided in front of the sprayer nozzle, such as a shroud to limit back spray, a rake to disturb soil prior to treatment, a tapered director to focus spray in corners, or a fan shaped outlet to provide a wide spray.
