    • 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.
    • 本发明涉及农药对植物的具体递送。 更具体地说,本发明涉及一种组合物,其基本上由包含至少一个结合结构域的靶向剂组成,所述结合结构域特异性结合完整活体植物上的结合位点,以及农业化学品或农用化学品的组合。 本发明还涉及特异性结合完整活的植物上的结合位点的结合结构域。 更具体地说,本发明涉及包含包含4个构架区和3个互补决定区的氨基酸序列或其任何合适的片段的结合域,其中所述结合结构域能够将载体结合或保留在植物上。 在一个优选的实施方案中,本发明涉及特异性结合毛状体,气孔,角质层,微孔,刺,刺,根毛或蜡层的结合结构域。 本发明还涉及一种用于将植物递送至植物的方法,用于改善农业化学品在植物上的沉积,以及使用包含所述结合结构域的靶向剂将植物上的所述农业化学品保留,以及保护植物的方法 针对生物或非生物胁迫或使用该胁迫控制植物生长。 此外,本发明涉及一种制造特异性靶向农药载体的方法。
