METHOD AND DEVICE FOR SELECTIVELY COLLECTING MATERIAL AND ORGANISMS ON PLANTS

摘要

The invention has reference to a procedure for selective collection of material and organisms around and on the plants where the material/organisms exist. Some kinds of the material/organisms are collected by exposing the plants to an air current between a blower outlet (7) and a suction hood (5). According to the invention stimuli signals are aimed at the plants in order to influence other kinds of material/organisms to leave the plants and/or to avoid congregating on the plants, so they cannot be exposed to the air current. The invention has also reference to a device for realizing the procedure.
