Squall has been tested in various studies and field surveys.

Squall improves the performance of crop protection as wel as fertilizers. The active ingredients in the spray mix reach target much better with 0.5% Squall included in the tank mix. Moreover, scientific field tests confirm the significant improvement of rain fastness if Squall is added to the tank mix: 50% more of active ingredients are still on the crop after a standard rain shower compared to the tank mix without Squall.

Spray drifting away...

Spray drift can be a major problem in all spraying operations. Drift onto neighbouring crops, hedges, parks and gardens can cause considerable damage as well as reducing the amount of active reaching the intended target. Spray drift can be caused by a number of factors including:

  • Wind velocity
  • Nozzle choice
  • Sprayer pressure
  • Vehicle speed
  • Boom height
  • Incorrect equipment setting

The benefits of Squall as anti drift agent in the tank mix:

  • Reduces wind drift
  • Reduces damage to adjacent areas
  • Reduces runoffs
  • Reduces contamination of surface water
  • Increases volume of active ingredients on the crop

The first 10 years...

Research was pioneered by professor Daniel Bonn at the École Normale Supérieure in Paris. Daniel is currently professor of physics at the University of Amsterdam and director of the prestigious Van der Waals-Zeeman Institute of Physics. He heads the GreenA R&D team. His fundamental work on this subject caught a lot of attention in the international press and science journals. He was awarded the Marie Curie Excellence Award for outstanding research projects in 2003.

The development of Squall into an agroculture innovation has been made possible with the financial support of Life-Eureka, the programme of the European Commission in the period 2004-2008. A year later, the Dutch Ministry of Infrastructure & Environment granted financial support for the further development of Squall to protect the water around farm land. Many tests have been executed on the fields by Wageningen University, the University of Amsterdam as well as by official test institutions in The Netherlands, Belgium and Germany. In 2012, Squall acquired an official permit in the Netherlands for spraying near surface water (TCT).


In 2013, DLV Plant, the leading, independent advisory and research partner for the vegetative sectors from Wageningen, compared the most popular tank adjuvants for their performance. In this test, Squall came out as the winner: the best deposition agent and the only adjuvant with strong anti-drift performance. The deposition on the leaves of roses, onions, chrysanthemums and potatoes were all superior. The deposition of spray on the crop improved up to 5 times compared to water without Squall.

Cost efficient

Squall has been designed to reduce the amount of drift in spraying operations. It contains a patented formula of unique polymeric ingredients and optimised surfactants to decrease the number of small fine driftable droplets in the spray pattern. Squall is the cost effective and sustainable application boost for the spraying of crop protection.

Spray sticking on the crop

From various scientific field tests it can be concluded, spray with Squall inside improves the deposition on the crop at least by 19% up to 74%. Hence, Squall improves the effectiveness of agrochemicals when added to the solution in the spray tank. Many agrochemical manufacturers recommend the use of an adjuvant with their products but other products can also benefit from the use of Squall. Squall can increase the biological efficacy by improved spreading and increased coverage of the leaf ensuring that pesticides coat the target in the most efficient way to maximise the effectiveness of that pesticide.

The best result?

Squall can be used in combination with crop protection products and fertilizers as well as biostimulants. For the best result, we recommend that you follow the instructions carefully.
