What term describes a disease caused by a pathogen that multiplies and can be transmitted from plant to plant?

• A. Infectious plant disease
• B. Insect
• C. Insecticide
• D. Label

Answer: (A)

Infectious plant disease describes a disease caused by a pathogen that multiplies within a plant and can be transmitted to other plants. Pathogens such as fungi, bacteria, and viruses reproduce in hosts and can spread through spores, water, wind, or vectors, leading to the spread of disease from plant to plant. This is different from issues that don’t spread between plants, like nutrient deficiencies or chemical injuries. An insect is a living organism that might spread disease or cause damage, but it isn’t the disease itself. An insecticide is a product used to kill insects, not a disease. A label is just product information. So the term that best fits is infectious plant disease.
