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.

“…Resistant cassava clones were characterized by low leaf loss over some time (Indiati, 2012). According to Poovizhiraja et al (2018), host plants' morphological and chemical components, especially plant nutrients, cause severe crop damage and yield losses. Note: WAI = weeks after infestation; ns = not significant Numbers in the same column followed by the same letter are not significantly different based on the DMRT test at 5 %.…”

“…The response of different cassava cultivars to mite attack can be influenced by various factors, including leaf morphology (leaf shape, leaf color, leaf thickness, and cuticle thickness) (Radhakrishnan et al, 2015). In addition to differences in leaf morphology, the content of chemical compounds or nutrients in cassava leaves can also affect the level of mite attack on leaves (Poovizhiraja et al, 2018). Santoso and Astuti (2019) reported that every cultivar showed different resistance against T. kanzawai.…”

“…It was found that mite showed a gradual increase in population build up from the first week of September until getting peak in the last week of September, 2014 and afterwards, a decrease in T. urticae population was recorded until November. Poovizhiraja et al (2017) [52] noted the effect of various irrigation levels with different watering frequency viz., on daily basis, once in a week, twice in a week with an untreated control on various preferred host plants of T. urticae like, okra, eggplant and tomato and revealed that daily irrigation is the most unsuitable moisture regime which supported a large number of number of T. urticae population by maintaining the turgor pressure of the cell and succulency of leaf which in turn encouraged the uninterrupted feeding process.…”

Marigold (Tagetus sp.) is a commercially exploited flower crop and is having a prominent place in ornamental horticulture. Agriculture is having a large impact on human economics and the emergence of red spider mite, Tetranychus urticae as a serious pest of marigold is a major concern. It leads to an economic yield reduction in crops depending on cropping seasons and agro-climatic conditions. Once it is established in an area, it is hard to get rid of it due to its high fecundity, dispersal techniques, short life cycles, rapid development of resistance to acaricides and adaptability to various ecological conditions. There is an urgent need to create awareness for this acarine and its behaviour for its timely management. This review gives a complete picture of the two spotted spider mite, Tetranychus urticae, including its pests, biology, population dynamics, effect of environment and the damage it causes to marigold crop. Awareness through this documentation will open new scope for its early detection on marigold crop.
