Kasugamycin hydrochloride is widely used in agriculture as an effective bactericide and fungicide. It is particularly effective against bacterial and fungal diseases in crops such as rice, fruits, and vegetables. The chemical works by inhibiting protein synthesis in pathogens, thereby preventing the spread of infections. It is often applied as a foliar spray to protect plants from diseases like rice blast and bacterial leaf blight. Due to its low toxicity to humans and animals, it is considered a safer option for disease management in integrated pest control systems. Additionally, it is used in some regions to combat antibiotic-resistant strains of plant pathogens, making it a valuable tool in sustainable agriculture practices.
