The field of plant pathology has adopted targeted genome editing technology as one of its most crucial and effective genetic tools. Due to its simplicity, effectiveness, versatility, CRISPR together with CRISPR-associated proteins found in an adaptive immune system of prokaryotes have recently attracted the interest of the scientific world. Plant disease resistance must be genetically improved for sustainable agriculture. Plant biology and biotechnology have been transformed by genome editing, which makes it possible to perform precise and targeted genome modifications. Editing offers a fresh approach by genetically enhancing plant disease resistance and quickening resistance through breeding. It is simpler to plan and implement, has a greater success rate, is more adaptable and less expensive than other genome editing methods. Importantly CRISPR/Cas9 has recently surpassed plant science as well as plant disease. After years of research, scientists are currently modifying and rewriting genomes to create crop plants which are immune to particular pests and diseases. The main topics of this review are current developments in plant protection using CRISPR/Cas9 technology in model plants and commodities in response to viral, fungal, and bacterial infections, as well as potential applications and difficulties of numerous promising CRISPR/Cas9-adapted approaches.

The world population is projected to reach 9.8 billion in 2050, and 11.2 billion in 2100 (United Nations) and people will need food, and decrease the farming land. Thus, the importance of Internet of Things (IoT) and Computer Science (CS) in plant disease management are increasing now-a-days. Mobile apps, remote sensing, spectral signature analysis, artificial neural networks (ANN), and deep learning monitors are commonly used in plant disease and pest management. IoT improves crop yield by fostering new farming methods along with the improvement of monitoring and management through cloud computing. In the quest for effective plant disease control, the future lies in cutting-edge technologies. The integration of IoT, artificial intelligence, and data analytics revolutionizes monitoring and diagnosis, enabling timely and precise interventions. Cloud computing facilitates real-time data sharing and analysis empower farmers to combat diseases with unprecedented efficiency. By harnessing these innovations, agriculture can embrace sustainable practices and safeguard crop health, ensuring a bountiful and secure future for the global food supply.
