Nanopesticides and Nanofertilzer ,the future of agriculture?

 by

      Raghav V. Budur.


Firstly what is nanotechnology?

Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering.

  So now what  difference these nano formulations may bring in the nature

The excess use of chemical fertilizers and  unsafe pesticides has led to pollution and serious health issues. Nanoscience  may solve these issues by providing nano materials of higher performance.

Nanofertilizers such as   N, P, K, Fe, Mn , Zn, Cu, Mo and carbon nanotubes show better release and targeted delivery efficiency. Nanopesticides such as Ag, Cu, SiO2, ZnO and nanoformulations show better broad-spectrum pest protection efficiency in comparison with conventional pesticides.

WHY DO WE REALLY NEED THEM?

Augmentation of the food production to fulfilment of

hunger of increasing population is one of the major challenges in the world using sustainable practices. The growth of population is increasing continuously and reached up to 7.37 billion . To overcome this situation, the use of chemical fertilizers and pesticides,

genetic modified or disease-resistant crop varieties has

been in trend in farming communities from previous five

decades. However we know what all are the consequences of using chemical fertilisers and pesticides. Nanoformulations may solve  those issues.

THE SAD PART OF OUR STORY

When considering all nanoproducts that will possibly emerge in the food and agriculture sectors, there is a widely accepted consensus that there is insufficient reliable data currently to allow a clear safety assessments. When considering only nanoagrochemicals, the paradigm behind a classical risk assessment approach (i.e., hazard × exposure) is suitable, but applying approaches used within the current regulatory framework directly would result in a number of pitfalls . Exposure assessment relies on investigations into the environmental fate of a compound. There have been a limited number of studies investigating nanoagrochemicals . It is also likely that fate and hazard endpoints are not adequately determined through the application of protocols that were developed previously for other types of chemicals . Overall, the current level of knowledge appears to be largely insufficient for a reliable assessment of the risks associated with the use of nanoagrochemicals.

CONCLUSION

prohibiting the application of nanopesticides until they are proven entirely safe is unrealistic, as all pesticides are inherently toxic (at least to the target pest) and, thus, associated with some risk. It is also important to note that some nanopesticides may offer a number of benefits, including increased efficacy, reductions in application rates, exposure to non-target organisms or the development of resistances. In the scientific literature, the last couple of years have seen increasing incentives to use nanotechnology to develop products that may be less harmful to the environment relative to conventional agrochemicals.

Python; Introduction and Installation -PART 1

Image
by    Aneesh R. Prabhu Introducing Python. P ython is an interpreted, high-level and general-purpose programming language. Created by Guido van Rossum and first released in 1991.  Python's simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed. What makes Python special? Often, programmers fall in love with Python because of the increased productivity it provides. Since there is no compilation step, the edit-test-debug cycle is incredibly fast. Debugging Python programs is easy: a bug or bad input will never cause a segmentation fault. Instead, when the interpreter discovers an error, it raises an exception. When the program doesn't catch the exception, the interpreter...

A second home: Mars

Image
by      Chinmaya Srivatsa .K Photo by  Nicolas Lobos  on  Unsplash Introduction to the planet  Ever since the discovery of this red celestial object by Galileo Galilei in the year 1610, this planet has taken our breath away and left us awestruck. Galileo Galilei discovered this planet using a primitive telescope during September of 1610. He became the first man to observe the planet using a telescope. Nowadays, millions observe it during the last week of July of every year when it is closest to our Earth, many countries are planning unmanned space missions to Mars and a few countries are even planning to colonise Mars. If you are interested in the modern history and future of human activities on Mars, this is the right article for you.  Geographic factors  Mars has a number of interesting geographical factors which are similar to Earth’s including Mountains, Valleys, Plains, Volcanoes and Elevated Plains. But, the Martian surface has geograph...

Python; Print Command- PART 3

Image
 by       Aneesh R. Prabhu    The most common instruction given to a computer in any programming language is output some data either to user or console etc. Output Any type of of information we get from the computer is called output and y'll know it. This response you will get from a computer. An instruction is a unit of work for a computer. Values A value is a unit or a multiple units of information, like numbers, strings , character, character of numbers or etc. Print function If we need the computer to show any out, we use print function. Correct way of using Print function  is by typing print(arguments) . We need to pass a argument that computer should display. Arguments When a value is used in a function call, it is called an argument. Arguments are enclosed in parentheses after the function name. i.e <function_name>(<argument>) i.e print("hello world") In the above statement print is the function name and "hello world" is the arg...
