Windblown particles are controlled by a porous tubular control device formed from a sheet of netting material having a plurality of interconnected webs which define a plurality of apertures. The sheet of netting material assumes a three-dimensional tubular configuration. The tubular configuration is oriented to confront the wind and cause the wind blown particles to flow through the apertures of two vertically oriented portions of the tubular netting sheet to create aerodynamic drag and turbulence altering effects which stabilize, deposit and retain the windblown particles. The control device is effective in preventing the wind erosion of snow, sand or dust over an area much greater than the area occupied by the device.
