Biotic, abiotic stresses and their unpredictable combinations severely reduce plant growth and crop yield worldwide. The different chemicals (pesticides, fertilizers, phytoregulators) so far used to enhance crop tolerance to multistress have a great environmental impact. In the search of more eco-friendly systems to manage plant stresses, chitin, a polysaccharide polymer composed of N-acetyl-D-glucosamine and D-glucosamine and its deacetylated derivative chitosan appear as promising tools to solve this problem. In fact, these molecules, easily obtainable from crustacean shells and from the cell wall of many fungi, are non-toxic, biodegradable, biocompatible and able to stimulate plant productivity and to protect crops against pathogens. In addition, chitin and chitosan can act as bioadsorbents for remediation of contaminated soil and water. In this review we summarize recent results obtained using chitin- and chitosan-based derivatives in plant protection against biotic and abiotic stresses and in recovery of contaminated soil and water.

“…In contrast to soil drenching, application of Ch to leaves of mycorrhizal plants had significant effects: Tomato plants treated with different concentrations of Ch showed enhanced shoot biomass, higher numbers of flowers and lower mycorrhization rates (Figure 3). El Amerany et al [24] found similar result in tomato plant grown in soil amended with chitosan and compost. The positive effects of Ch on tomato growth and flowering might be due to its properties to act as anti-transpirant, to activate ROS scavenging system, to enhance stomatal conductance, and to stimulate growth of xylem vessels [24,36].…”

“…This might be due to the physical properties of Ch used. In fact, the amendment of soil with Ch has offer an excellent binding surface to nitrogen ions of compost [24] and its ability of chelating ions would be increased with its solubilization in a slight acidic solution leading to a protonation of amino groups. Therefore, the capacity of Ch to act as chelator might make some essential ions inaccessible to the plant [35].…”

“…However, there is only limited information about their mechanisms as well as the question, who will impact the other one first. In addition, it had been reported that the amendment of soil with Ch increased the colonization of tomato roots with AMF only in nutrient-deficient soil; however, the mycorrhization pathway was deactivated under the amendment of soil with combined bio-fertilizers: Ch and compost [24].…”

Nowadays, applying bio-organic fertilizer (e.g., chitosan, Ch) or integrating beneficial microorganisms (e.g., arbuscular mycorrhizal fungi, AMF) are among the successful strategies to promote plant growth. Here, the effect of two application modes of Ch (foliar spray or root treatment) and Ch-derived nanoparticles (NPs) on tomato plants colonized with the AMF Rhizophagus irregularis were analyzed, thereby focusing on plant biomass, flowering and mycorrhization. An increase of shoot biomass and flower number was observed in arbuscular mycorrhizal (AM) plants sprayed with Ch. The interaction with AMF, however, was reduced as shown by decreased mycorrhization rates and AM-specific gene expression. To get insights into Ch effect on mycorrhization, levels of sugars, jasmonates, abscisic acid, and the expression of two chitinase-encoding genes were determined in mycorrhizal roots. Ch had no effect on sugar and phytohormone levels, but the reduced mycorrhization was correlated with down- and upregulated expression of Chi3 and Chi9, respectively. In contrast, application of NPs to leaves and Ch applied to the soil did not show any effect, neither on mycorrhization rate nor on growth of mycorrhizal plants. Concluding, Ch application to leaves enhanced plant growth and flowering and reduced interaction with AMF, whereas root treatment did not affect these parameters.

BACKGROUNDMonolepta hieroglyphica (Motschulsky) is an important agricultural pest that causes significant economic losses in terms of crop production. Conventional pesticide spraying treatments can result in pesticide drift, endanger nontarget organisms, and cause pests to fly away, resulting in unsatisfactory prevention and control effects. To study the effect of thiamethoxam on the control of maize M. hieroglyphica, a field experiment was conducted to determine the optimal thiamethoxam application dose, its spatial and temporal distribution dynamics and its dietary risk based on its control effect when applied by spray and drip irrigation.RESULTSThe results of the field trials showed that compared with spray irrigation, drip irrigation resulted in greater control starting from the 5th day. This result was due to the hysteresis effect of thiamethoxam being first absorbed by the roots and then continuously transferred upward, where it accumulates. After 30 days of drip irrigation with 75 and 150 g a.i. ha‐1 thiamethoxam, the control effect on M. hieroglyphica was 32.41‐49.44% and 69.77‐80.57%, respectively. The results of the dietary risk assessment showed that the risk of thiamethoxam ingestion through maize kernels was acceptable regarding its effect on human health.CONCLUSIONSDrip irrigation with thiamethoxam can improve the effective utilization rate of pesticides, achieve precise control of maize M. hieroglyphica, and provide a new method for sustainable agricultural production.This article is protected by copyright.
