“…Also, the highly favourable effects of Ag NPs on grains/spike, 100-grain weight, and grain yield per pot in wheat [ 27 ]. Exogenous application of nano-glycyrrhizic acid and nano-curcumin to the soybean ( Glycine max ) may induce specific pathways that have a significant impact on plant growth, physiological activities, secondary metabolites, various pathways, and active compound production [ 4 , 23 ].…”

“…Ten plant leaves were selected from each replicate fortnightly, and the number of T. urticae , was counted with the aid of a stereomicroscope at the Acarology Lab. The mean density of total life stages (immature and adults) was statically analyzed using analysis of variance (ANOVA) and assessed among all treatments of soybean to evaluate the mean reduction percentage and variations in the different treatments and water irrigation mode on the total accumulation number of T. urticae [ 4 , 17 ].…”

“…Drought stress increases the number of mites and plant damage, as well as stress in the diet, which affects the density of the spider mites and the egg laid/female population. T.urticae is a highly polyphagous and notorious plague that spreads rapidly to develop pesticide resistance [ 3 , 4 ]. It is a major soybean pest, causing a major decrease in yield.…”

Modern nanotechnology has been credited as one of the most significant inventions of the 21st century. Many agricultural disciplines have been affected by nanotechnology in agriculture. Pest control based on natural compounds needs to be enhanced, and enhancing plant growth under climate change conditions, with increasing periods of drought in many countries, is a very vital aim. Thus, the effect of curcumin nanoparticles (Cu-NPs) and glycyrrhizic acid nanoparticles (GA-NPs) as a foliar application under water deficit on natural infestation with the two-spotted spider mite Tetranychus urticae, plant growth and yield, anatomical and chemical parameters were investigated during this study. The obtained results revealed that drought stress over the two studied seasons significantly increased the population of T. urticae and decreased all morphological and yield characteristics. The application of three mM GA-NPs reduced the mite population average by 39% while using the same concentration of Cu-NPs caused a 33.9% reduction percentage under drought stress. Using 1 mM GA-NPs gave the highest averages of plant height, number of branches, and leaves/plant fresh and dry weight. Moreover, the number of pods, 100 seed weight and seed yield (kg/ha) increased significantly as a result of spraying with GA-NPs under water deficit. From the results, water deficit decreased the values of the leaf and stem anatomical parameters. Treatment with Cu-NPs or GA-NPs under drought stress increased the thickness of mid-vein, xylem, and phloem tissues. Likewise, such treatment increased stem diameter due mainly to the increase in the thickness of cortex, phloem, and xylem tissues compared with the control. Spraying plants with GA-NPs at 1 mM increased the percentages of nitrogen, phosphor, and potassium in seeds in addition to total chlorophyll. Moreover, glutamate, aspartate, leucine, arginine, Lysine, glycine, tyrosine, tryptophan, and methionine concentrations did not differ significantly (p > 0.05) in response to all the studied levels of Cu-NPs or GA-NPs either under normal irrigation or drought condition. In light of these findings, researchers and producers should apply and test both Cu-NPs and GA-NP as nano-fertilizer natural sources on economically viable crops.

“…Furthermore, the exogenous application of H 2 O 2 increases plant tolerance to stress. Common beans treated with H 2 O 2 exhibited enhanced resistance against Tetranychus urticae (Alakhdar & Shoala, 2021). The exogenous application of H 2 O 2 was also reported to activate the oxidative defense system against drought in soybean (Darmanti et al, 2021).…”

Field-grown rice (Oryza sativa L.), when exposed to various environmental stresses, produces high amounts of reactive oxygen species, such as H 2 O 2 . MicroRNAs (miRNAs) play crucial roles in plant stress responses. This study characterized the functions of H 2 O 2 -regulated miRNAs in rice. Small RNA deep sequencing revealed that miR156 levels decreased following H 2 O 2 treatment. Searches of the rice transcriptome and degradome databases indicated that OsSPL2 and OsTIFY11b are miR156-target genes. Interactions between miR156 and OsSPL2 and OsTIFY11b were confirmed using transient expression assays through agroinfiltration. In

Plasma-activated water (PAW) is receiving increased attention as a booster of seed germination and seedling vigor, and some studies have described use of PAW to manage crop pathogens. Here, we examined physicochemical properties of two PAWs (referred to as PAW 6.0 and 9.4 min with atmospheric plasma jet) and assessed “their indirect effects” (applied as supplementary irrigation) on host suitability of tomato plants (Solanum lycopersicum L.) to two-spotted spider mites (Tetranychus urticae Koch). Exposure of water to cold plasma significantly lowered pH and increased concentrations of H2O2, NO2−, and NO3−. Supplementary PAW irrigations elicited significant increases in leaf composition of several elements (N, P, K S, Ca, and Mg), leaf reflectance, plant size, and trichome densities (except non-glandular trichomes on the adaxial surface). Preference bioassays revealed significant avoidance of settling and reduced oviposition by two-spotted spider mites on leaf discs from PAW-irrigated plants compared to those from untreated control plants. Performance bioassays showed a significant decrease in two-spotted spider mite populations on PAW-irrigated plants. Results presented in this study provide comprehensive support to the hypothesis that indirect effects of supplementary PAW irrigation significantly reduce host plant suitability to two-spotted spider mites. PAW 6.0 may be slightly better than PAW 9.4, and this difference in performance is discussed in this study. Applications of PAW as supplementary irrigation are likely highly compatible with other IPM tactics and should be considered an innovative and sustainable component in twenty-first-century pest management.
