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

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

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/…
