Nanoscale delivery systems have the potential to improve the effectiveness of agrochemicals while reducing their negative environmental impacts. Herein, we explore the use of lignin nanoparticles (LNPs) to enhance the translocation of methoxyfenozide (MFZ), a non-systemic pesticide, in soybean plants under hydroponic conditions. LNPs (113.8 ± 3.5 nm and zeta potential – 53.3 ± 6.9 mV) were synthesized by emulsion evaporation from lignin-graft-poly(lactic-co-glycolic) acid and MFZ was incorporated into the LNPs (2.7% w/w). Twenty eight day old soybeans were grown hydroponically and were treated with 0.01, 0.1 or 1 mg/ml of LNPs. Plants were harvested after 6, 12, and 24 h of continuous hydroponic exposure to the roots and the concentration of MFZ was quantified in root, stem, and leaf tissues. The results suggest effective and time dependent transfer of MFZ from the hydroponic suspension to the roots …
