Last week, in the pepper greenhouse of Kwekerij Moors, the biological pest phytoseiulus, among others, was released in the hunt for spider mites. By preventively creating a good biological balance, the growers hope to minimize the use of plant protection products. A special feature is that the biological control agents have been deployed using a technique devised by the in-house technical department. "By mounting a blower on the spray robot, we learn these critters fly, and we don't have to deploy them manually," a video also shows.
