A device (1) for thinning in fruit growing includes at least one support (3) connected to a tube (2) to which are connected to one or More flexible elements/whips (6), the support (3) connected by at least one plate (10) to an operating machine. The tube (2) is connected to at least one air compressor to supply at least air with variable pressure and/or flow rate to the tube (2), the tube (2) being crossed by the flow of air flowing in the one or more flexible elements (6). The flexible elements/whips (6) are hollow and are able to move when crossed by the flow of air, the movement of the whips modulated by compressed air. The whips (6) have a random oscillatory movement for striking the parts to be thinned with a modulated force depending on the pressure and flow rate of the air flow delivered.

A method is provided for thinning fruits (F) and/or flowers belonging to plants (A) located beneath orientable photovoltaic sensors (C), with the shade from the sun cast onto the plants being adjusted by changing the orientation of the sensors. In the method by virtue of the orientation of the sensors, the plants are kept in the shade for a sufficient duration to induce thinning by shading said plants from the sun.

Perforated rotating attraction drum of a general cylindrical shape and featuring openings, this drum being fitted for being mounted on a leaf-stripping head of the leaves of a foliage wall such as a row of vine-stock, characterized in that it features the superposition of a plurality of rings presenting an outside cylindrical surface, and of a plurality of annular openings made between two successive rings, these openings allowing the passage of a suction air flow across and towards the inside of the perforated rotating attraction drum featuring, internally, means of rigid assembly of the plurality of stacked rings and a coupling means to a motorization for its rotational drive.

An apparatus comprising a chamber having a smooth inner surface, the chamber including a first hemisphere and a second hemisphere, wherein the first hemisphere is removably attached to the second hemisphere; a plurality of apertures located on a bottom center surface of the second hemisphere; a plurality of nozzles, each of the plurality of nozzles having an inlet and an outlet, wherein each of the outlets penetrate the plurality of apertures without intersecting the smooth inner surface; an air compressor; a compressed air regulator; an air hose connected to each of the inlets of the plurality of nozzles and the air compressor.
