Abstract: A dust-control apparatus may be used in combination with tilling, cultivating, harvesting, construction machinery, and other mobile soil treatment implements. The apparatus applies mist to dust particles where the mist is created by pumping water or other liquid through nozzles. Because the apparatus is used in combination with the operation of the dust-generating machinery, the dust suppressing mist is applied nearly simultaneously to the generation of the dust by the agitation of the soil by the machinery. In one embodiment of the device, the operation of the pump or valves which control liquid flow to the nozzles is automatically activated by a optical sensor. The optical sensors cause either the starting of a pump or opening of a valve thereby increasing or decreasing the pressure and/or volume of the liquid upon the dust level reaching a preset trigger point as detected by the sensor.
