Abstract: A tarp system for controlling psylla and other orchard pests that includes two or more tarps sized and shaped to fit the width of an orchard row, a roller with handle, a container, oil, a pole apparatus for dislodging pests, and a broom. A method for using the tarp system includes grounding a first tarp below a tree, saturating a roller with oil in the container, rolling oil onto the tarp with the roller, and tapping tree branches over the tarp to dislodge pests on to the tarp, placing a second tarp slightly under the first tarp, sweeping debris from the first tarp to the second tarp, and disposing of the second tarp.

Abstract: A stadium and arena seating system is provided which preferably utilizes pre-cast concrete tread surfaces and metallic or other non-concrete vertical risers therebetween. The pre-cast concrete treads have non-concrete front embeds embedded within the front of the treads respectively, and an integrally formed upwardly extending concrete lip portion for shedding water from the upper adjacent riser that eliminates the need for a non-concrete rear embed. The front embeds may comprise a metallic or other non-concrete material similar to the vertical risers. The vertical risers are arranged in a shingled fashion overlapping the upwardly extending concrete lip portion of the treads to provide water and debris shedding. In a further aspect, the upwardly extending concrete lip portion may optionally be formed with a plurality of pre-formed mounting holes through which fasteners for fastening a lower portion of the riser may be received.
