Nanotechnology is transforming agriculture by providing innovative solutions to enhance crop yields, improve disease resistance, and reduce environmental impact. Nanofertilizers, nano-pesticides, and nano-fungicides are being developed to promote sustainable agriculture. These nanoparticles can be designed to release nutrients or pesticides in a controlled manner, reducing waste and minimizing environmental pollution. Nanopesticides are a novel approach to pest management, offering a more efficient and environmentally friendly alternative to traditional pesticides. Target-release nano-pesticides can be designed to release pesticides in response to specific environmental signals, such as temperature, humidity, or light. pH-sensitive nano-pesticides, enzyme-responsive nano-pesticides, and temperature-responsive nano-pesticides are some examples of target-release nano-pesticides. Nanofungicides have emerged as a promising tool for plant disease management. Metal nanoparticles, such as silver and copper, have shown antimicrobial properties and can be used to control fungal and bacterial diseases. Chitosan nanoparticles have also shown promise in inducing viral resistance in plants and controlling fungal diseases. Other types of nanoparticles, such as carbon nanotubes and silica nanoparticles, have also been explored for their potential in plant disease management.
