Comparison of Three Commercial Automatic Boom Height Systems for Agricultural Sprayers

RR792 - Decontamination of agricultural sprayers

Bugged by automatic sprayers.

Just as houses are made of stones, so is science made of facts. But a pile of stones is not a house, and a collection of facts is not necessarily science. Bugged by Automatic Sprayers Automatic insecticide dispensers are designed to keep restaurants, schools, and other public settings free from annoying and unsanitary flying insects. They may also do something else: sicken at least some of the ...

An Empirical Comparison of Three Commercial Information Visualization Systems

An empirical comparison of three commercial information visualization systems on three different databases is presented. The systems use different paradigms for visualizing data. Tasks were selected to be "ecologically relevant", i.e. meaningful and interesting in the respective domains. Users of one system turned out to solve problems significantly faster than users of the other two, while use...

Evaluation of Three Commercial Backpack Sprayers with Aqualuer® 20-20 Against Caged Adult Aedes Aegypti.

Three commercially available backpack sprayers were evaluated with Aqualuer® 20-20 (20.6% permethrin, active ingredient; 20.6% piperonyl butoxide, technical) against caged adult Aedes aegypti in semifield trials in northeastern Florida. Two battery-powered sprayers, Birchmeier and Hudson, were compared with the standard hand-pump SOLO 425 sprayer, which is currently used in pest management oper...

Methodology for the Regulation of Boom Sprayers Operating in Circular Trajectories

A methodology for the regulation of boom sprayers working in circular trajectories has been developed. In this type of trajectory, the areas of the plots of land treated by the outer nozzles of the boom are treated at reduced rates, and those treated by the inner nozzles are treated in excess. The goal of this study was to establish the methodology to determine the flow of the individual nozzle...
