... Surface application of insecticides on turfgrass for control of many subsurface grubs is not very efficient. It can be potentially hazardous to people, pets and other animals exposed to the insecticides. To reduce this danger, three injection systems were developed to place insecticides below...

... A study was initiated to develop an automated injection system that would permit pesticide concentrate to be metered and mixed without the operator handling it manually or coming in contact with the chemical. A special jet nozzle assembly was designed that would allow the concentrate...

... of this success can be attributed to the injection of chemicals through the drip systems. Mechanical injectors have enabled the application of N-P-K fertilizers and chelated micronutrients directly to drip systems resulting in considerable flexibility and greater application efficiency. In addition, exceptional...
