In the city of Delft this afternoon. It is my favourite city in Holland with so much history. If you travel to Holland, this needs to be on your list https://t.co/gdsQl3BZKi

See Encarsia formosa & Eretmocerus eremicus from blisterpack to control whitefly. Poinsettia crops can prevent whitefly from becoming a problem with a proactive approach using Bio cutting dips & BCA techniques. Like to learn more? Contact us for more information. @BioWorksInc

Many Mum cuttings are started in June. Now is the time think about pest problems and preventing them, using BCAs and pro active dipping before sticking them. cuttings in the picture were dipped and every plug tray has a sachet with A. cucumeris. Like to learn more? @BioWorksInc

Greenhouses can be quite beautiful.

Amblyseius cucumeris sachets are little production units of these great little predatory mites, protecting plants from thrips & broadmites from getting established. Applying these sachets before the baskets go up to avoid suprises when the baskets come down to ship @BioWorksInc

[Ronald Valentin @RVBioControl]

Time to hang baskets.....and to make sure that they are protected against thrips and broadmites. Applying sachets with Amblyseius cucumeris is the best way to avoid these peat problems from getting established. #biocontrol @BioWorksInc
