Wear-resistance of Eclipse LD offers significant benefits

Says Wil Vollebregt from Vollebregt Optimal cleaning

The spraying companies are working full tilt to get the greenhouses ready for the new season. There are many suppliers of removable shading agents on the market. The choice is extensive. Wil Vollebregt of Vollebregt Optimal Cleaning each year critically reviews the supply.

One of the products he likes to apply to greenhouses is Eclipse LD® produced by Sudlac. “The quality has improved considerably over the last two years. In my view, the most important aspect of chalk solutions is their wear-resistance. Eclipse LD is recommended even in thin concentrations. Furthermore, we naturally also spray Optifuse when a grower has a greater need for growth light and diffusivity.”

Sudlac originally is a French company. Does Wil speak French as well then? “No. That’s not necessary,” he laughs. “Ruben Lensing and Michiel Seignette both are Dutch. We do not exchange a word of French and the communication between us is excellent. Things are going well. They are practical people.”

In 1997, Wil Vollebregt together with Ronald van Zijl, founded the spraying company Sproeibedrijf van Zijl-Vollebregt BV. As of 1 January 2016, Wil continued on his own with the company Vollebregt Optimal Cleaning. In the meantime, each year he performs cleaning work on some 600 hectares on the inside of greenhouses, while the mechanical application of chalk and the removal of chalk on the outside covers approximately 800 hectares. His customer base includes vegetable growers as well as flower growers and every once in a while he travels across the border to apply chalk.
