The invention relates to an agricultural implement (16) having at least one device (18) for processing plant stubble (44), with which it is possible to combat pests such as the European corn borer effectively. Said plant stubble processing device (18) comprises a rotational body (24) having an axis of rotation (26) and a rotating circumferential surface (28), wherein the axis of rotation (26) of the rotational body (24) extends at a predetermined angle relative to the horizontal plane, and additionally comprises a mating body (36) having a mating surface (38) which is positioned at a predetermined horizontal distance (42) opposite the circumferential surface (28) of the rotational body (24), wherein the predetermined horizontal distance (42) is dimensioned so as to be smaller than a diameter of the plant stubble (44) to be processed. The plant stubble (44) is taken between the circumferential surface (28) of the rotating rotational body (24) and the mating surface (38) of the mating body (36) and rotated about the longitudinal axis of the stubble and preferably also crushed so that the stubble is destroyed and also pulled out of the ground if necessary.
