An electrostatic backpack sprayer: potential for mosquito control.

A Southwest Electrostatic Sprayers, Inc., nozzle was configured to a Hudson PortaPak backpack. A test was run to compare deposition of BVA no. 13 oil by the electrostatic nozzle to a standard nonelectrostatic nozzle as collected by Teflon slides. Results indicate that 100% greater deposition occurred with the electrostatic nozzle.

PA-9: Technology to Improve Sprayer Accuracy

A number of new technologies have been introduced over the last several years aimed at improving the accuracy of spray application, but do they really work? The purpose of this document is to highlight the most common causes of application errors then discuss the array of new sprayer technologies that are becoming available, how they might affect application accuracy, and pitfalls involved in u...

Ergonomics evaluation of a lever-operated knapsack sprayer.

The lever-operated knapsack sprayer, a manually operated piece of equipment, is widely used by Indian farmers for the application of agricultural chemicals. The study reported here is an ergonomics evaluation of one model of this type of sprayer. Data on 18 body dimensions and the shape of the back were collected for 10 subjects and their relevance in sprayer design are discussed. During the op...
