An applicator for moving particulates, comprising: a receptacle in fluid contact with a hopper that stores particulates; the receptacle being attached to a delivery tube having an outlet that receives an airflow, wherein the air flowing through the delivery tube ushers particulates out of the delivery tube via the outlet; the receptacle further comprising a first section having side walls and a bottom surface with an opening, the first section being configured for receiving particulates from the hopper, characterized in that the receptacle further comprises a second section through which the particulates pass before moving to the delivery tube via an opening in the delivery tube, the second section having an opening in a surface and the second section being arranged for placement of a disc comprising a surface with at least one cutout so that the disc is positioned in an area between the respective first and second sections (116, 119); a particulate guide that fits through a first hole located in the first section bottom surface and a second hole located in the second section surface, the particulate guide being configured for rotating to move particulates that are received into the first section; wherein said openings (101, 102) in the first section bottom surface and second section surface are aligned to form a fluid path for particulates to pass from the first section of the receptacle into the delivery tube when the at least one cutout of the disc is positioned between the respective openings (101, 102), but to restrict passage of particulates through the respective openings (101, 102) when a solid surface of the disc is positioned between the respective openings (101, 102). a receptacle in fluid contact with a hopper that stores particulates; the receptacle being attached to a delivery tube having an outlet that receives an airflow, wherein the air flowing through the delivery tube ushers particulates out of the delivery tube via the outlet; the receptacle further comprising a first section having side walls and a bottom surface with an opening, the first section being configured for receiving particulates from the hopper, characterized in that the receptacle further comprises a second section through which the particulates pass before moving to the delivery tube via an opening in the delivery tube, the second section having an opening in a surface and the second section being arranged for placement of a disc comprising a surface with at least one cutout so that the disc is positioned in an area between the respective first and second sections (116, 119); a particulate guide that fits through a first hole located in the first section bottom surface and a second hole located in the second section surface, the particulate guide being configured for rotating to move particulates that are received into the first section; wherein said openings (101, 102) in the first section bottom surface and second section surface are aligned to form a fluid path for particulates to pass from the first section of the receptacle into the delivery tube when the at least one cutout of the disc is positioned between the respective openings (101, 102), but to restrict passage of particulates through the respective openings (101, 102) when a solid surface of the disc is positioned between the respective openings (101, 102).
