Agrochemical compositions comprising antibodies binding to sphingolipids

This disclosure relates to agrochemical and biological control compositions for combating pests, more specifically plant pests, comprising at least one polypeptide, which specifically binds to a pest. The disclosure further provides methods for protecting or treating a plant or a part of a plant from an infection or other biological interaction with a plant pathogen, at least comprising the step of applying directly or indirectly to a plant or to a part of a plant, an agrochemical composition, under conditions effective to protect or treat a plant or a part of a plant against a infection or biological interaction with a plant pathogen. Further provided are methods for producing such agrochemical compositions and formulations, to polypeptides with a specific pesticidal activity comprised within an agrochemical formulation, to nucleic acids encoding such polypeptide and to plants comprising chimeric genes comprising such nucleic acids.
