Which term describes a disease capable of being transmitted from plant to plant due to a multiplying pathogen?

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

Answer: (A)

An infectious plant disease is defined by its ability to spread from plant to plant because the pathogen multiplies inside the hosts. Pathogens such as fungi, bacteria, viruses, or nematodes replicate within plants and can be transmitted to new plants through spores, water, contaminated tools, soil contact, or vectors. This contagious nature is what sets infectious diseases apart from other issues. The other options don’t describe a disease: an insect is a pest, an insecticide is a chemical to kill insects, and a label is just product information and doesn’t describe disease transmission.
