چکیده
but also improves the uniformity of the spray pattern. Turbulence chamber nozzles are available in a turbo flood tip and now in the turbo flat-fan design. The turbo flatfan design shows great improvements in pattern uniformity when compared to the extended range flat-fan and other drift reduction flat-fan designs. In addition, the turbo flat-fan has significantly reduced the percentage of driftable droplets under a wide range of pressures. Both of the turbo designs are adapted for use on the boom to spray straight down with a 50 percent overlap.

Testing and Listing of Drift Reducing Sprayers in Germany D. Rautmann Biological Research Centre for Agriculture and Forestry, Application Techniques Division, Messeweg 11-12, D-38104 Braunschweig
Drift is one of the main paths of plant protection products to non-target organisms. In Germany great efforts are made to reduce drift. Therefore sprayers are tested concerning their drift reducing ability in relation to the German basic drift values which have been determined on the basis of more than 180 drift trials with conventional sprayers. A classification system with classes of at least...

The objective of this study was to evaluate different strategies for the application of entomopathogenic nematodes (EPN). Three different models of spray nozzles with air induction (AI 11003, TTI 11003 and AD-IA 11004), three spray pressures (207, 413 and 720 kPa), four different additives for tank mixtures (cane molasses, mineral oil, vegetable oil and glycerin) and the influence of tank mixtu...
متن کاملMethodology 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...
متن کاملOutcomes on the Spray Profiles Produced by the Feasible Adjustments of Commonly Used Sprayers in “Tendone” Vineyards of Apulia (Southern Italy)
The objective of the research was to assess the outcomes on the spray patterns produced by the different feasible adjustments of two different air blast sprayers and one mist blower sprayer, commonly employed for treatments to Apulian “tendone” vineyards. The spray profiles of these machines and the respective refinements affected by the alteration of the available adjusting devices were evalua...
متن کاملCanopy penetration and deposition of barrier sprays from electrostatic and conventional sprayers.
An experimental study was conducted to investigate the usefulness of electrostatic and conventional sprayers for barrier applications. Two conventional and three electrostatic sprayers were used in the study. Usefulness of the sprayers was rated based on penetration of spray into and deposition onto 2 sides of leaves on natural vegetation. Bifenthrin (Talstar adulticide) was applied at labeled ...
