“…MSNs were studied for storage and controlled release of the fungicide metalaxyl. The fungicide, loaded into MSN pores from an aqueous solution by a rotary evaporation method, was released in soil and water very slowly over 30 days . In other studies, MSNs proved to be effective carriers for the delivery of the natural pesticide avermectin, being able to protect the AI against UV degradation and to slow its release, dependent on the pore diameter and shell thickness …”

Natural compounds and living organisms continue to play a limited role in crop protection, and few of them have reached the market, despite their attractiveness and the efforts made in research. Very often these products have negative characteristics compared to synthetic compounds, e.g., higher costs of production, lower effectiveness, lack of persistence, and inability to reach and penetrate the target plant. Conversely, nanotechnologies are having an enormous impact on all human activities, including agriculture, even if the production of some nanomaterials is not environmentally friendly or could have adverse effects on agriculture and the environment. Thus, certain nanomaterials could facilitate the development of formulated natural pesticides, making them more effective and more environmentally friendly. Nanoformulations can improve efficacy, reduce effective doses, and increase shelf‐life and persistence. Such controlled‐release products can improve delivery to the target pest. This review considers certain available nanomaterials and nanotechnologies for use in agriculture, discussing their properties and the feasibility of their use in sustainable crop protection, in particular, in improving the effectiveness of natural bio‐based agrochemicals. © 2019 Society of Chemical Industry

“…Metalaxyl fungicide encapsulated with MSN was investigated for the reduced loss and changed release profile. MSN entrapped fungicides showed controlled release behaviour as about only 11.5% of the free metalaxyl was released into the soil over a time period of 30 days as compared to the free fungicides in which 76% was released within the same time period ( Wanyika, 2013 ). Campos et al (2015) prepared two different types of NPs, polymeric, and solid lipid NPs loaded with a combination of tebuconazole and carbendazim and investigated their controlled release behavior and storage properties.…”

Nanotechnology has become a very advanced and popular form of technology with huge potentials. Nanotechnology has been very well explored in the fields of electronics, automobiles, construction, medicine, and cosmetics, but the exploration of nanotecnology’s use in agriculture is still limited. Due to climate change, each year around 40% of crops face abiotic and biotic stress; with the global demand for food increasing, nanotechnology is seen as the best method to mitigate challenges in disease management in crops by reducing the use of chemical inputs such as herbicides, pesticides, and fungicides. The use of these toxic chemicals is potentially harmful to humans and the environment. Therefore, using NPs as fungicides/ bactericides or as nanofertilizers, due to their small size and high surface area with high reactivity, reduces the problems in plant disease management. There are several methods that have been used to synthesize NPs, such as physical and chemical methods. Specially, we need ecofriendly and nontoxic methods for the synthesis of NPs. Some biological organisms like plants, algae, yeast, bacteria, actinomycetes, and fungi have emerged as superlative candidates for the biological synthesis of NPs (also considered as green synthesis). Among these biological methods, endophytic microorganisms have been widely used to synthesize NPs with low metallic ions, which opens a new possibility on the edge of biological nanotechnology. In this review, we will have discussed the different methods of synthesis of NPs, such as top-down, bottom-up, and green synthesis (specially including endophytic microorganisms) methods, their mechanisms, different forms of NPs, such as magnesium oxide nanoparticles (MgO-NPs), copper nanoparticles (Cu-NPs), chitosan nanoparticles (CS-NPs), β-d-glucan nanoparticles (GNPs), and engineered nanoparticles (quantum dots, metalloids, nonmetals, carbon nanomaterials, dendrimers, and liposomes), and their molecular approaches in various aspects. At the molecular level, nanoparticles, such as mesoporous silica nanoparticles (MSN) and RNA-interference molecules, can also be used as molecular tools to carry genetic material during genetic engineering of plants. In plant disease management, NPs can be used as biosensors to diagnose the disease.

“…153 Synthetic porous silica particles, especially MSNs, have been widely investigated for biocide delivery. [157][158][159][160] In this case, the physicochemical characteristics of the mesoporous silica particles, i.e. pore size and surface area, are closely correlated to the biocide adsorption capacity and subsequent release rate.…”
