Visiting some poinsettia growers this week, some real outstanding quality poinsettias ready to find their new home. Healthy Root system on these poinsettia plants (Early innoculation Rootshield Plus). Clean Plants, no whitefly AND no insecticides, with BCA Eretmocerus eremicus.

exciting to see a new growing season getting started. Growers at propagators & rooting stations play such an important role to produce high quality young plants. However, is Zero Tolerance realistic? GrowerTalks - February 2020 - Sending Out the Troops ballpublishing.com/magazine/gt_20…

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 BioWorks

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? BioWorks
