Development And Preliminary Evaluation Of An Integrated Individual Nozzle Direct Injection And Carrier Flow Rate Control System For Pesticide Applications, Joe D. Luck, Scott A. Shearer, Michael P. Sama

Biosystems and Agricultural Engineering Faculty Publications

Direct injection systems for agricultural spray applications continue to present challenges in terms of commercialization and adoption by end users. Such systems have typically suffered from lag time and mixing uniformity issues, which have outweighed the potential benefits of keeping chemical and carrier separate or reducing improper tank-mixed concentration by eliminating operator measurements. The proposed system sought to combine high-pressure direct nozzle injection with an automated variable-flow nozzle to improve chemical mixing and response times. The specific objectives were to: (1) integrate a high-pressure direct nozzle injection system with variable-flow carrier control into a prototype for testing, (2) assess the …
