Described is the specific delivery of agrochemicals to plants. More specifically, a targeting agent has at least one binding domain that specifically binds to a binding site on an intact living plant. Such binding domains include a peptide having 4 framework regions and 3 complementary determining regions, or fragment(s) thereof, wherein the binding domains bind or retain a carrier onto a plant. Described are binding domains that specifically bind trichomes, stomata, cuticle, lenticels, thorns, spines, root hairs, or wax layer. Further described are methods for delivering agrochemicals to a plant, for depositing agrochemicals on a plant, and for retaining the agrochemicals on a plant, using targeting agents comprising the binding domains, and to methods for protecting a plant against stress or controlling plant growth. Also, described are methods for manufacturing a specifically targeting agrochemical carrier. |
