TL;DR: It is inferred that fungicides must be examined in vitro for their possible adverse effects on soil micro flora before their application in agricultural fields and the prerequisite of application of fungicide-tolerant PGPR strains as bioinoculants so that their PGP activities may not be suppressed under fungicide stress.
TL;DR: In this article , the authors summarized the current state of research and provided a forward-looking view of the use of CS-NPs in plant disease management, and evaluated the performance of maize (CS-NP-loaded Cu, Zn, SA, and silicon) and soybean (CSNP-loading Cu, NPK, thiamine, silicon, and Ag).
Abstract: By 2050, population growth and climate change will lead to increased demand for food and water. Nanoparticles (NPs), an advanced technology, can be applied to many areas of agriculture, including crop protection and growth enhancement, to build sustainable agricultural production. Ionic gelation method is a synthesis of microparticles or NPs, based on an electrostatic interaction between opposite charge types that contains at least one polymer under mechanical stirring conditions. NPs, which are commonly based on chitosan (CS), have been applied to many agricultural fields, including nanopesticides, nanofertilizers, and nanoherbicides. The CS-NP or CS-NPs-loaded active ingredients (Cu, saponin, harpin, Zn, hexaconazole, salicylic acid (SA), NPK, thiamine, silicon, and silver (Ag)) are effective in controlling plant diseases and enhancing plant growth, depending on the concentration and application method by direct and indirect mechanisms, and have attracted much attention in the last five years. Many crops have been evaluated in in vivo or in greenhouse conditions but only maize (CS-NP-loaded Cu, Zn, SA, and silicon) and soybean (CS-NP-loaded Cu) were tested for manage post flowering stalk rot, Curvularia leaf spot, and bacterial pustule disease in field condition. Since 2019, five of eight studies have been performed in field conditions that have shown interest in CS-NPs synthesized by the ionic gelation method. In this review, we summarized the current state of research and provided a forward-looking view of the use of CS-NPs in plant disease management.
TL;DR: Generally, the maximum toxicity to plant growth promoting traits of Mesorhizobium was shown by glyphosate, thiamethoxam and hexaconazole, at three times the recommended rate among herbicides, insecticides and fungicides, respectively.
TL;DR: The cytotoxicity assay performed on vero cell lines by MTT (3-(4,5-Dimethylthiazol-2-yl)-2-5-Diphenyltetrazolium Bromide) assay confirmed that nanoformulation is less toxic than commercial formulation of pesticide.
TL;DR: The results suggest that the stimulation of invertase activity in mildewed leaves altered the source-sink relationship of the leaf leading to an accumulation of soluble carbohydrates and a decrease in sucrose synthesis and that application of hexaconazole successfully prevented development of the fungus but that the metabolic alterations following the initial infection were not reversible within the time scale studied.
