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.
