A product applicator is secured to the blower tube of a portable air blower and incorporates an adapter nozzle assembly and product storage container. The adapter nozzle assembly is located at a distal end of the blower tube, and includes a substantially hollow tubular housing and a discharge nozzle located inside the housing. The housing has a discharge end and a connecting end adapted for being arranged inline with the discharge airstream supplied by the blower. The product storage container is located proximate the housing, and is designed for storing a product to be discharged through the nozzle. A flow regulator is adapted for selectively adjusting a supply of product from the container to the discharge nozzle.
