4. Introduction:
Agriculture is the major sector that provide food for human
The properties of nanoparticles associated with the size, shape
and molecular orientation can react with the agricultural host
tissue suggesting great application potential in the field of
agriculture.
Nanobiotechnology eliminate accumulation of several
pesticides from agricultural field and also use of several chemical
fertilizers which is one of the hot issues for today’s agriculture.
This can enhance the quality of life
5. Continued:
The application of this technology possesses a great deal of
difficulty in agriculture sector.
This new technology is also helpful in the Nano-DNA Crystals
process, Recycling of Agricultural Waste, Biosensor, Silkworm
Industry and Honeybee culture etc.
At present though the application of nanotechnology in
agriculture is in infant stage.

Nanoparticles can serve as
‘magic bullets’, containing
herbicides, chemicals, or genes,
which target particular plant
parts to release their content.
Nanocapsules can enable effective
penetration of herbicides through
cuticles and tissues, allowing slow and
constant release of the active
substances.
11. Nanotech Delivery Systems for Pests, Nutrients,
and Plant Hormones
•Nanosensors dispersed in the field can also detect the
presence of plant viruses and the level of soil nutrients.
•Nano encapsulated slow release fertilizers have also
become a trend to save fertilizer consumption and to
minimize environmental pollution.
12. Continued…
• Nanobarcodes and Nano processing could also be
used to monitor the quality of agricultural products.
• Used to study the effect on PGRs especially Auxin*.
13. Nanoparticles and Recycling

21. The Impact of Nanotechnology
• Nanotechnology offer solutions to problems in food and
agriculture.
• As in biotechnology, issues of safety on health,
biodiversity, and environment along with appropriate
regulation are raised on nanotechnology.
• However, nanotechnology products such as anti-
bacterial dressings, stain-resistant fabrics, and suntan
lotions are available.
22. Conclusion:
• Dream of automated, centrally controlled agriculture can become
reality now.
• Modern agriculture is need of hour because conventional agriculture
will not be able to feed an ever increasing population with changing
climate, depleting resources and shrinking landscape.
Chemists have successfully crafted three-dimensional molecular structures, a breakthrough that unites biotechnology and nanotechnology. They made DNA crystals by producing synthetic DNA sequences that can self-assemble into a series of three-dimensional triangle-like patterns. The DNA crystals have “sticky-ends” or small cohesive sequences that can attach to another molecule in an organized fashion. When multiple helices are attached through single-stranded sticky ends, there would be a lattice-like structure that extends in six different directions, forming a three-dimensional crystal as illustrated in Figure 1. This technique could be applied in improving important crops by organizing and linking carbohydrates, lipids, proteins and nucleic acids to these crystals
responsible for root growth and seedling establishment. Scientists at Purdue University developed a nanosensor that reacts with auxin. This interaction generates an electrical signal which can be a basis for measuring auxin concentration at a particular point. The nanosensor oscillates, taking auxin concentration readings at various points of the root.
When cotton is processed into fabric or garment, some of the cellulose or the fibers are discarded as waste or used for low-value products such as cotton balls, yarns and cotton batting. With the use of newly-developed solvents and a technique called electrospinning, scientists produce 100 nanometer-diameter fibers that can be used as a fertilizer or pesticide absorbent. These high-performance absorbents allow targeted application at desired time and location.
Ethanol production from maize feedstocks has increased the global price of maize in the past two years. Cellulosic feedstocks are now regarded as a viable option for biofuels production and nanotechnology can also enhance the performance of enzymes used in the conversion of cellulose into ethanol. Scientists are working on nano-engineered enzymes that will allow simple and cost-effective conversion of cellulose from waste plant parts into ethanol
Since there is a continuous source of rice husk, mass production of nanosilica through nanotechnology can alleviate the growing rice husk disposal concern
