Abstract: A spraying apparatus including an agricultural sprayer and a mounting bracket for affixing the sprayer to the trunk or limb of a tree or bush is disclosed. The mounting bracket is easily adjustable as to height, to radial position about the tree or bush, and to angle between the sprayer and the trunk or limb. This mounting bracket has a base for interfacing with the tree or bush and a connector for adjustably connecting the base with a fastener that encircles the trunk or limb, thus providing height and radial adjustment. The bracket further has a support member that supports the sprayer in spaced relation to the trunk or limb. The support member is capable of assuming a plurality of orientations, thus providing the angular adjustment. A method for spraying trees and bushes is further provided that entails the use of the spraying apparatus, determining a preferred position and orientation of the sprayer, and affixing the sprayer in that position on the tree or bush.

Abstract: An improved irrigation system for low-volume flow to individual plants or trees is presented. The system involves a detachable irrigation emitter with a flow deflector. In addition, an easily interchangeable dual flow pattern adapter is presented that can be slipped over the irrigation emitter in two different ways, thus providing two different deflection faces to produce two different flow patterns. Thus, with only one adapter, three distinct spray patterns may be selected at each plant site with much less time and labor than in previous systems. In a further embodiment, flow pattern adapters with three and four deflection surfaces are described, offering the choice of four and five distinct spray patterns at each plant site, respectively.

Abstract: A low volume irrigation system includes a length of a thin-walled plastic distribution tube extending horizontally along a row of plants with a plurality of vertical hand assemblies extending downwardly from and spaced along the distribution tube, each hang assembly having a lowermost sprinkler and an intermediate feed tube for delivering water from the distribution tube to the sprinkler. Each hang assembly is made from a material that is selected to maintain the sprinkler of each hang assembly located generally underneath the distribution tube, irrespective of any axial twisting of the tube.

Abstract: A low volume irrigation sub-assembly is dimensioned to be removably fitted in an extensible riser of a conventional pop-up spray housing. The sub-assembly has an upstanding low volume emitter extending generally axial to the direction of elongation of the housing and the riser, and includes a filter and flow control device for restricting the pressure of water passing between the interior of the riser and the emitter aperture.
