Black scurf disease caused by Rhizoctonia solani, was a serious and common disease on potato worldwide. Effect of nanoparticles forms of Tri-calcium phosphate, copper oxide and silicon dioxide nanoparticle was evaluated at five concentrations to control black scurf disease in vitro and in vivo. Examination of treated R. solani with different tested nanoparticle was done using Transmission Electron Microscope (TEM). Activities of defense related enzyme were determined in artificially inoculated potato plants and tubers (cv. Spunta) with R solani. Physical characteristics of tested nanoparticles exhibit that all of them are spherical in shape and varied in their sizes. Also, all tested nanoparticles exhibited inhibitory effect of R. solani. Non-copper oxide was the most effective one (56.42 %) in suppressing the mycelial growth of R. solani at concentration 250 µl/L. The TEM examination of treated R. solani with different nanoparticles exhibit that instability they caused in cell wall thickness, abnormalities of nucleus and disappearance of nuclear membrane. All tested nanoparticles reduced of incidence and severity% of black scurf disease at concentrations 150 and 200 µl/L. during 2014 and 2015 seasons. Results cleared also that treating potato plants with different tested nanoparticles affected positively the activities of poly phenoloxidase, peroxidase, catalase and chitinase enzymes in leaves and tubers.

“…Cu + 2 can also be synthesized as Cu(OH) 2 NPs. In general, the toxicity of copper compounds has been exploited to protect agricultural crops from many pests, including those causing fungal infections (Montes et al, 2015;Kalatehjari et al, 2015;Bramhanwade et al, 2016;Epstein and Bassein, 2001;Begum et al, 2015;Fan et al, 2011;El-Habbaa et al, 2016;Wightwick et al, 2008;Stansly and Kostyk, 2015;Thind and Singh, 2015;Ferreira et al, 2007), and copper pesticides are now applied on some "organic" crops (Baker et al, 2002;Winter and Davis, 2006). Their use as an antimicrobial agent has also been considered in several applications (Emam et al, 2014;Shebl, 2014;Mjos et al, 2016;Congrádyová et al, 2014).…”

Comparative environmental fate and toxicity of copper nanomaterials

A B S T R A C TGiven increasing use of copper-based nanomaterials, particularly in applications with direct release, it is imperative to understand their human and ecological risks. A comprehensive and systematic approach was used to determine toxicity and fate of several Cu nanoparticles (Cu NPs). When used as pesticides in agriculture, Cu NPs effectively control pests. However, even at low (5-20 mg Cu/plant) doses, there are metabolic effects due to the accumulation of Cu and generation of reactive oxygen species (ROS). Embedded in antifouling paints, Cu NPs are released as dissolved Cu + 2 and in nano-and micron-scale particles. Once released, Cu NPs can rapidly (hours to weeks) oxidize, dissolve, and form CuS and other insoluble Cu compounds, depending on water chemistry (e.g. salinity, alkalinity, organic matter content, presence of sulfide and other complexing ions). More than 95% of Cu released into the environment will enter soil and aquatic sediments, where it may accumulate to potentially toxic levels (> 50-500 μg/L). Toxicity of Cu compounds was generally ranked by high throughput assays as: Cu + 2 > nano Cu(0) > nano Cu(OH) 2 > nano CuO > micron-scale Cu compounds. In addition to ROS generation, Cu NPs can damage DNA plasmids and affect embryo hatching enzymes. Toxic effects are observed at much lower concentrations for aquatic organisms, particularly freshwater daphnids and marine amphipods, than for terrestrial organisms. This knowledge will serve to predict environmental risks, assess impacts, and develop approaches to mitigate harm while promoting beneficial uses of Cu NPs.

“…Nowadays, the world's population is growing very rapidly, and it is expected to reach 8.5 billion by 2030 [11], which means that the demand for food, natural resources like water, land to establish cities and cultivate, will also increase [12]. In the same matter, the climate change due to the pollution has caused a very negative impact on the crop production [12]. In that sense, the food industry needs to come up with quick and novel alternatives in order to fulfill the heavy demand for food and the shortage of land and water.…”

“…Currently, some of the solutions to cope with those problems have been the use of fertilizers, pesticides and genetically modified organisms (GMO) [13]. Nevertheless, the indiscriminate use of chemical compounds to increase the crop production or efficiency, has caused serious issues like heavy soil, air and water contamination, human and animal diseases and destabilization of the ecosystems [12] [14]. For example, related to the overuse of pesticides, many of the pests that affect the crops have developed resistance, analogous to the bacterial antibiotic resistance, which causes that the farmers tend to use more quantity and stronger pesticides, some of them being quite toxic [15].…”
