Effect of poly(dl-lactide-co-glycolide) nanoparticles or cellulose nanocrystals-based formulations on Pseudomonas syringae pv. tomato (Pst) and tomato plant development
Journal of Plant Diseases and Protection 123 (6), 301-310
Abstract: Nanotechnology can change the scenario of current tools minimizing the chemical inputs in plant protection. Here, novel poly(dl-lactide-co-glycolide acid) (PLGA) copolymer-based biopolymeric nanoparticles (NP) and cellulose nanocrystals (CNC) were evaluated as basic materials for their use as nanocarriers to develop innovative plant protection formulations. PLGA NP were synthesized and tested, and the effect of natural surfactants, such as starch and CNC, on the NP final properties was investigated. Moreover, CNC were evaluated as possible nanostructured formulation to be directly applied in plant protection treatment. The effect of both, PLGA NP and CNC, was investigated with respect to their influence on the survival of the causal agent of bacterial speck disease (Pseudomonas syringae pv. tomato, Pst), on plant development and damages (phytotoxicity effects), on tomato plant. The proposed nanocarriers are able to cover, with a uniform distribution, the tomato vegetal surfaces without any damage and to allow a regular development of the tomato-treated plants. Moreover, starch–PLGA NP formulations resulted unsuitable for Pst survival and multiplication along the time on the tomato plants surface. A great potentiality comes up of these nanocarriers on plants to carry out and to release antimicrobial active ingredients useful in innovative and sustainable plant protection strategies.
