Abstract
An applicator for weedicide or other agricultural or horticultural treating liquid consists mainly of a swabbing brush having a multiplicity of pliant filaments, preferably of cruciform cross-section, trailing from a supply conduit to which the treating liquid is fed from a tank, the supply conduit which may be tractor-mounted being advanced over an area to be treated, so that the brush filaments with treating liquid running down them, are tailed over the area so that the liquid is applied directly to the area being treated. The swabbing brush, when tractor-mounted, is pivoted to swing back if encountering a tree or other obstacle, to be returned by a spring when the obstacle is passed.

An applicator for agricultural and horticultural treating liquids, said apparatus comprising a supply conduit, a feed means for treating liquid and a swabbing brush which extends down from the supply conduit, which receives treating liquid from said feed means, and which, in opration as the applicator is advanced over an area to be treated, trails over the area to be treated and deposits treating liquid thereon, said swabbing brush comprising a multiplicity of pliable non-absorbent filaments which depend from support means disposed within an upper part of the supply conduit and which pass freely through a slotted aperture in a lower part of the supply conduit, and the feed means comprising a feed tube disposed within said supply conduit and at least one spray nozzle attached to said feed tube, and controllable means for feeding treating liquid under pressure onto the upper parts of the filaments between the support means and the slotted aperture so that the treating liquid descends down the filaments gravitationally.
