Introduction to agrotop H ogrotop venturi nozzles agrotop venturi nozzles Since their introduction by agrotop for agricultural sprayers in 1993, venturi nozzles have become successful in all types of chemical application, making them indispensable in modern agriculture, for effective and economic spraying as well as compliance with environ- mental standards. Drift is one of the main problems in spray technology responsible for over 1/3 of all off target applications. This means that in more than 30 % of the applications farmers are wasting money- Some basic principles can help in...

Venturi nozzles Droplet size The droplet size of a spray is generally expressed as the VAAD (Volume Median Diameter). The VMD is mainly influenced by pressure and nozzle size. When the pressure rises, VMD is reduced.The VMD rises when using larger nozzle sizes. Droplet size recommendations vary due to different modes of action of chemicals. There is also a difference between venturi and standard nozzles. Contact chemicals generally require smaller droplets of lower VMD for good Droplet size The droplet size is generally given as VMD = Volume Median Diameter Smaller droplets Spray Volume...

Venturi nozzles drift reduction Normally, spraying should only be done when the risk of drift is low. However, often the farmer has to apply a chemical treatment when the drift risk is high, e.g. short "application window", which means the need to apply to large areas in a short time. Drift potential of different nozzle types Hollow Standard Low agrotop cone flat fan drift venturi nozzles Nozzle type There are different advances in spray technology to reduce the drift potential.The easiest and most efficient is still to increase droplet size. However, simply using larger droplets can mean a...

Venturi nozzles When the air-filled droplets of a venturi nozzle hit a surface, e.g. a leaf, the bubbles burst, distributing finer droplets all over the surface, improving the coverage (see pictures on Larger droplets provide better penetration, even in dense canopies.The bursting droplets guarantee an excellent coverage, sometimes even on the underside of the leaves. Effect of venturi nozzles on coverage Venturi Standard Big droplets may roll off the leaf venturi nozzles In any situation where drift is a problem, the use of a venturi nozzle is highly recommended. agrotop venturi nozzles...

venturi nozzles Many farmers around the world use double flat fan venturi nozzles to optimise their application agrotop has more than 20 years of experience in developing our venturi nozzles to fit best to the local farmer conditions in every part of the world, pushing new trends in application During this period the agrotop double flat fan venturi nozzles have shown remarkable improvements: • Better efficacy and higher yields • Uniform coverage of all parts of the plant, including difficult to hit areas like small or inclined leaves. • Improved all around coverage and deposition on...

Field tests showing the efficacy of the TurboDrop® HiSpeed nozzles rear side Over the last few years dozens of field trials have been performed by agrotop in cooperation with different partners from sprayer manufacturers, chemical industries, official and private consultancy groups, local dealers or farmer groups to show the benefit of using TurboDrop® HiSpeed nozzles by agrotop. Some reports of the outstanding results of these trials can be found on the German version of our homepage www.agrotop.com/berichte or contact us directly for more details. TurboDrop® HiSpeed nozzles in practice...
