The HAP carriers with three sizes (20 nm, 60 nm, and 80 μm) and three types of Cu-based pesticides (OrganCu, InorganCu, and NanoCu) were prepared and compared. The nanopesticide (K60) prepared using the 60 nm HAP carrier and NanoCu commercial pesticide were proved with a particle size of less than 200 nm, and exhibited potential in long-term application performance. At low concentrations (10 mg kg<small><sup>−1</sup></small>), NanoCu pesticides significantly affected the diversity of soil microorganisms. Notably, K60 decreased the negative influence on microorganism diversity compared with the original commercial pesticides, and improved alpha diversity and microbial species composition variation. Besides, K60 enhanced the phosphorus deficiency resistance of lettuces <em>via</em> the adjustment of microelement homeostasis. In particular, 5 μM K60 increased the Cu and P uptake in lettuce root by 77.81% and 76.12%, and increased the Mg and K uptake in root by 44.95% and 39.74%.
