The effect of a colloidal solution of Cu,Zn-nanoparticles on pro-oxidative/antioxidative balance and content of photosynthetic pigments and leaf area of winter wheat plants of steppe (Acveduc) and forest-steppe (Stolichna) ecotypes was investigated in drought conditions. It has been shown that Cu,Zn-nanoparticles decreased the negative effect of drought action upon plants of steppe ecotype Acveduc. In particular, increased activity of antioxidative enzymes reduced the level of accumulation of thiobarbituric acid reactive substances (TBARS) and stabilized the content of photosynthetic pigments and increased relative water content in leaves. Colloidal solution of Cu,Zn-nanoparticles had less significant influence on these indexes in seedlings of the Stolichna variety under drought.

“…For example, complete growth inhibitory effect of ZnO 2 nanoparticles was demonstrated on Allium sativum at the concentration of 50 µg mL −1 . 22 Recently, phytotoxicity of metal‐containing nanoparticles (Mn, Zn, Ag, Cu, and Fe) have been demonstrated by performing Allium test, which revealed manganese nanoparticles as a least phytotoxic nanocomposition . Further, numerous studies have also shown that prolonged exposure to the nanoparticles might be associated with decrease in mitotic index (MI) as well as increase in abnormalities in chromosomal behavior during cell division.…”

Nanobiotechnological application of copper nanoparticles has paved the way for advancement in agriculture owing to its bactericidal and fungicidal activities. Recently, researchers have focussed on bioinspired synthesis of copper nanoparticles as a viable alternative to existing physicochemical techniques. For the commercialization of nanocopper, the toxicity evaluation is a major issue. In this context, Citrus medica (L.) fruit extract-mediated copper nanoparticles were synthesized and its different concentrations (10, 20, 40, 60, 80, and 100 µg mL(-1) ) were evaluated for its effect on actively dividing cells of Allium cepa. The study clearly revealed that copper nanoparticles increased mitotic index up to the concentration of 20 µg mL(-1) . In addition, a gradual decline in mitotic index and increase in abnormality index was observed as the concentration of copper nanoparticles and treatment duration were increased. Aberrations in chromosomal behavior such as sticky and disturbed chromosomes in metaphase and anaphase, c-metaphase, bridges, laggard, disturbed telophase, and vacuolated nucleus were also observed.

“…The phytotoxic effect of metal NPs applied in the form of colloidal solutions on the growth of A. cepa roots decreased in the following order: Cu ≥ Zn ≥ Ag ≥ Fe [105]. CuO NPs were found to be more toxic than bulk CuO or dissolved Cu(II) ions to Landoltia (Spirodela) punctata [106] and Zea mays [107].…”

Nanoagrochemicals, such as nanopesticides, nanofertilizers or plant growth stimulating nanosystems, were primarily designed to increase solubility, enhance bioavailability, targeted delivery, controlled release and/or protection against degradation resulting in the reduced amount of applied active ingredients and finally in a decrease of dose-dependent toxicity/burden. This paper is a comprehensive up-to-date review related to the preparation and the biological activity of nanoformulations enabling gradual release of active ingredient into weeds and the body of pests and controlled release of nutrients to plants. The attention is also devoted to the decrease of direct environmental burden and economic benefits due to application of nanoformulations, where less amount of active ingredient is needed to achieve the same biological effect in comparison with bulk. The application of nanotechnology in the areas such as food packaging, food security, encapsulation of nutrients and development of new functional products is analysed. The use of nanoparticles in biosensors for detection of pathogens and contaminants as well as in DNA and gene delivery is discussed as well. Benefits and health risks of nanoagrochemicals are highlighted, and special attention is given to nanoecotoxicology and guidelines and regulatory documents related to the use of nanoformulations in agriculture and food industry.
