The application of pesticides is often not considered in any detail in university and polytechnic curricula, especially in developing countries. Because application equipment involves chemicals and issues of toxicity and environment, the topic is frequently omitted from agricultural engineering courses. This, in turn, means that extension agents are weak in this area reinforcing the need for effective practical training for those who apply pesticides. In this study, an experimental swirl chamber nozzle (SCN) was designed, developed and constructed. Thereafter, a series of tests were carried...
