Designing and developing nanoagrochemicals would not only serve the purpose but they have to be tested to check how far they are environmentally friendly and their sustainability and affordability before farmers are convinced to use it. Media will help in taking sustainable nanoagro products to the nook and corner of the country.

dear colleague:

 first it is necessary to define that the word "nanotechnology" is used extensively to define the sciences and techniques that are applied at a nanoscale level. One of the main developments of nanotechnology is found in the sectors of agriculture and food, needing to involve almost all the disciplines of both basic and health sciences, as well as associated engineering.

In the case of agriculture, nanotechnology can be applied (and is already being done) for the treatment of some plant diseases, for the early detection of pathogens, for the improvement of the assimilation of essential nutrients by plants and even the construction of important nanobiosensors in certain biological processes.

Its use can increase the efficacy of commercial pesticides and insecticides by reducing the amount of application to the soil at significantly lower doses required for crops with the environmental improvement that implies.

nanotechnology is already generating very good results, there are already studies that confirm that metallic nanoparticles are effective against the pathogens of plants, insects and pests. In fact, nanoparticles can be used as new formulations of pesticides, insecticides and insect repellents by nanoemulsion or nanoencapsulation techniques. Nanoparticles of silica, polyethylene glycol, silver, aluminum, zinc oxide and titanium dioxide have been tested with promising results. The future of the agricultural industry can happen by using these materials as nanopesticides, nanofungicides and nanoherbicides and some companies are already developing them. In short, the application of nanotechnology to agriculture is a more respectful alternative to the environment.

However, another problem is how to bring these technologies to the farmer, because in this part there must be a greater social awareness about this field of science and the benefits that can bring it into practice. It is necessary to extend the use of these nanoproducts not only to large producers but also to small farmers in order to achieve all the necessary extension so that agriculture in general can benefit from nanotechnology

Agriculture is a 'cheap' industry and the cheapest nanoparticle systems are at least 2 orders of magnitude more expensive than the fertilizers used at present. The nitrates are easily soluble in water and do not need to be nanosized for rapid solubility, There would have to be substantial technical advantages for anyone to consider nano in this area.
