Crop disease research focuses on understanding the causes, symptoms, and impact of diseases that affect various crops, such as fruits, vegetables, grains, and plants. Researchers study the interactions between pathogens, plants, and the environment to develop strategies for disease prevention, management, and control. This research aims to improve crop productivity, reduce economic losses, and ensure food security for a growing global population. Methods used in crop disease research include field surveys, genetic studies, molecular biology techniques, and the development of disease-resistant crop varieties.
