What are indicator plants used for in viral infection detection?

Indicator plants are specifically utilized in the detection of viral infections because they exhibit visible symptoms that can alert growers to the presence of a virus before it affects the primary crop plants. These plants can be susceptible to specific pathogens and will often show signs of infection, such as stunted growth, leaf curling, or discoloration. By monitoring these indicator plants, farmers can take proactive measures to manage viral diseases, potentially preventing widespread damage to their crops.

This proactive strategy allows for early intervention, which is crucial in maintaining crop health and maximizing yield. The use of indicator plants acts as an early warning system, helping to identify viral threats in a timely manner. This is especially valuable in agricultural practices where monitoring every individual crop plant for early signs of viral infections might not be feasible.
