The present invention relates to an unprecedented line of products utilizing polymer-based stabilized nanoparticles for the production of self-sanitizing photocatalyst coatings for application to broad-spectrum agriculture, including: growth stimulation, pre- and post-harvest protection, reduced use of irrigation water and the use of pesticides with significant antimicrobial activities. The products described herein are easy to handle and apply, low cost of production and are intended for agribusiness using an unprecedented combination of polymeric compounds with nanotechnology active ingredients. Included in this invention are products intended for a variety of uses, including pre- and post-harvest protection, stimulation of plant growth, reduction of leaf sweating, rooting, and increased plant defense against external agents. This invention uses novel polymeric derivatives as stabilizers and fixers of nanoparticles, through the method of formation by ion gelation of nanoparticles aiming to obtain various effects, notably the stimulation of plant growth, increased productivity, rooting and defense induction. against pests and external attacks. Also part of the invention is the combined use of other substances in the composition of the line such as dispersants, catalysts, enzymes, oils, flavors and dyes.a presente invenção relata uma linha inédita de produtos utilizando nanopartículas estabilizadas em bases poliméricas para produção de coberturas fotocatalizadoras auto-sanitizantes para aplicação em agricultura com largo espectro de ações, incluindo: estímulo do crescimento, proteção pré e pós-colheita, redução do uso de água para irrigação e do uso de defensivos agrícolas com expressivas atividades antimicrobianas. os produtos aqui descritos são de fácil manipulação e aplicação, baixo custo de produção e destina-se ao agronegócio utilizando uma combinação inédita de compostos poliméricos com ativos utilizando nanotecnologia. fazem parte desse invento produtos desti
