Abstract: An agricultural spray implement (10) includes a plurality of removable valve/filter/nozzle cartridges (19). Each removable cartridge (19) has a single housing (20) that retains a magnetized filter (36), a high speed solenoid valve (31) and a spray nozzle (24). In the event the system filter of the spray implement is removed, fine particles which otherwise might clog the solenoid valves are stopped from entering the solenoid valves (31) by the magnetized filters (36) of the valve/filter/nozzle cartridges (19). Each cartridge (19) has a clean-out purge valve so that its magnetized filter (36) can be unclogged without removal of the magnetized filter (36) from the cartridge housing (20). A light emitting diode of the cartridge provides a visual indication that the cartridge is dispensing agricultural liquid. The light emitting diode is turned on when the solenoid valve (31) is controlled to be open. In some embodiments, the light emitting diode is not supplied with current until after the solenoid valve (31) has opened and only a smaller holding current is needed to hold the solenoid valve (31) open.

Abstract: Weeds (100) growing around the bases of the stalks of cotton plant (101) growing in a row (105 and 105A) in a cotton field are sprayed with herbicide without spraying the cotton stalks (101) or wasting herbicide on bare ground (107). The cotton plants are adequately mature that their stalks exhibit a significantly different spectral reflectance characteristic than the weeds typically growing amid the cotton. The cotton plants are adequately tall that the majority of the leaves of the cotton plants are disposed outside the area which can be sprayed using an electronically-controlled valve and nozzle (103). Light is transmitted toward an object (a cotton stalk, a weed, or soil) in the row and the reflected light is analyzed. If the object has a spectral characteristic of a growing weed, then the valve is activated and the object is sprayed with herbicide. If the object does not have the spectral characteristic of a growing weed, then the valve is not activated and the object is not sprayed with herbicide.

Abstract: An agricultural implement (a spray device) differentiates living plants (G(s), CP, PS) growing in a field from background materials (DL, AI, AT GV, DM, C) by detecting a change in slope of a reflectance characteristic (d[log{ref%}]/d[nm]) of objects in a field of view. By using a change in slope of the reflectance characteristic, a small percentage of living plant material in the field of view can be detected and the agricultural implement need not be calibrated to a particular background material. In some embodiments, if the change in slope is determined to exceed a predetermined threshold amount, then it is determined that a weed likely exists in the field of view and a solenoid-operated spray valve is opened at the appropriate time to spray the entire area (including the weed) that was in the field of view with herbicide.
