Spraying systems to protect crops against pests are still necessary maintain food production at the rates demanded by current population. However, today, it is crucial use precision agriculture reduce negative effects of pesticides and other agrochemicals such as fungicides. In particular, pressure fluctuations related transient states when using pulse-width-modulated nozzles (PMW) have been re...

Reducing populations of phlebotomine sand flies in areas prevalent for human leishmaniases is of ongoing importance to United States military operations and civilian populations in endemic regions. However, not enough is known regarding the efficacy of Department of Defense-approved pesticides and equipment against sand flies; specifically, the potential for ultra-low volume (ULV) pesticide app...

Quantitative assessment and pertinent adjustments of airblast sprayers can help improve spraying efficiency, reduce off-target drift negative environmental impacts. In such pursuit, a study was conducted to characterize liquid spray delivery four commonly used in the Pacific Northwest region United States. Powerblast (S1), Pakblast (S2), Turbomist 30P (S3), Columbia Accutec (S4) sprayer units w...

Based on the study of dimensional characteristics reeds, a sprayer is proposed for treatment panicles reeds growing in elements irrigation system rice checks. The boom offered has an original shape, sprayers which are located along trajectory parabola, taking into account placement upper points across width channel and equipped with protective chamber device, made form Archimedes spiral pitch e...

Abstract To eliminate the shortcomings of serial fan sprayers, JV “Agrikhim” developed a universal sprayer that treats crops based on controlled airborne flows introduced simultaneously within ± 90 0 from sprayer’s symmetry axis (a total 180 ) around entire perimeter treatment area width machine. The obtained dependences and nomogram built their basis allow setting required rate application wor...
