Application of agrichemicals

摘要

An improved roller applicator as described which is used to apply liquid herbicides or similar substances to weed foliage extending above a crop. The application device is in the form of a roller which is supplied by a controllable dispersal means which supplies an agrichemical product to the application roller. The application roller is shrouded in an enclosure which is constructed so as to surround at least a portion of the application roller whereby the portion which protrudes can brush the agrichemical product onto the weed foliage. The improved roller is specifically adapted to prevent spray and drip leakage from the application enclosure by means of sealing members arrayed linearly along the junction of the roller and the enclosure shroud. <IMAGE>
