Abstract: A herbicide applicator assembly (10) includes a liquid applicator (14) in the form of a resiliently compressible, unitary, porous foam mass with a substantially cylindrical applicator surface (20) for applying liquid from a source thereof. The liquid applicator (14) is rotatably mounted. A spacer wheel (30) extends radially beyond the applicator surface (20) to space the applicator surface (20) from any flat surface with which the spacer wheel (30) is engaged. The spacer wheel (30) is in fixed connection with a bush (52) with the liquid applicator (14) seated on the external periphery of the bush (52). The liquid applicator (14) is attached to the spacer wheel (30) to rotate in unison with the spacer wheel (30). The liquid applicator (14) is provided with an external edge (42) defined between the substantially cylindrical applicator surface (20) and an end surface (40) of the applicator (14).

Abstract: An applicator for applying liquid media has an applicator head (10) attached to a stem (1). The applicator head (10) includes a spherical applicator freely rotatable on an axle (6) which extends at right angles to the stem (1) that is of a length that an operator can hold the stem (1), and rest the surface of the applicator (10) on the ground. The applicator (10) has a porous resilient envelope (11) which surrounds a sleeve (7) located on the axle (6), a reservoir in the stem (1) charges the porous envelope (11) with liquid media.
