2. INTRODUCTION
The growing population of the world
demand the surge in production of
agriculture output.
To prevent the loss of crop, green
revolution provide chemical pesticides to
agriculture during 1930-1960.
WHO estimated more than 2000 billion
deaths every year.
Biopesticides are the possible solution for
reduction of adverse impact of chemical
pesticides.

3. Technological innovations are needed to improve agriculture
Nanotechnology offers potential solutions to the problems
● Increasing nutrient utilization efficiency
● Improving the efficacy of pest management
● Combating climate impacts
● Reducing adverse impacts
Opens wide array of opportunities in various fields

4. NANOPESTICIDES
Nanopesticides are nanostructures with
two to three dimensions between 1 to
200 nm, used to carry agrochemical
ingredients (AcI).
These ingredients can be
● Fixed on hybrid substrate
● Encapsulated in matrix
● Functional nanocarriers
Different structures of polymeric nanopesticides

(CRFs) For Biocides Application
Chemical Method

7. Physical Method

8. Stimuli-responsive Systems
Release of different compounds in an effective manner and at defined times
Technology that is still in an early stage of development
Two types
● enzyme-responsive system
● pH-responsive systems

9. pH-responsive systems
Enzyme-responsive system

10. Benefits Over Conventional Pesticides
● Safe handling of toxic materials
● Biodegradability
● Separation of incompatible materials
● Precision farming
● Increased stability in the environment
● Controlled and targeted release of encapsulated active compounds
● Reduces doses
● Improve efficiency of pesticides
● Residues below detectable limits

11. Commercial Limitations and Challenges
● Development of standardized methods
● Advances in knowledge of the interactions between nanomaterials
and plants or pathogens
● Development of strategies to track nanopesticides
● Lack of a clear and standardized definition of nanomaterials
● Development and implementation of legislation
