The present invention relates to specific delivery of agrochemicals to plants. More specifically, it relates to a composition, essentially consisting of a targeting agent comprising at least one binding domain that specifically binds to a binding site on an intact living plant and an agrochemical or a combination of agrochemicals. The present invention relates further to a binding domain that specifically binds said binding site on an intact living plant. More specifically, it relates to binding domains comprising an amino acid sequence that comprises 4 framework regions and 3 complementary determining regions, or any suitable fragment thereof, whereby said binding domains are capable to bind or retain a carrier onto a plant. In one preferred embodiment, the invention relates to binding domains which specifically bind trichomes, stomata, cuticle, lenticels, thorns, spines, root hairs, or wax layer. The invention relates further to a method for delivery of agrochemicals to a plant, for improving the deposition of agrochemicals on a plant,and for retaining said agrochemicals on a plant, using targeting agents comprising said binding domains, and to a method for protecting a plant against biotic or abiotic stress or controlling plant growth using the same. Also, the invention relates to a method for manufacturing a specifically targeting agrochemical carrier.
