Disease Control Principles Include:

The principles of disease control are designed to manage and reduce the incidence of diseases in agricultural settings effectively. The correct answer highlights three important strategies: genetic resistance, exclusion, and eradication.

Genetic resistance refers to the inherent ability of certain plant varieties or animal breeds to withstand diseases, which can significantly reduce reliance on chemical controls. This method involves breeding or selecting organisms that naturally repel or resist pathogens, thereby fostering a more sustainable agricultural system.

Exclusion is a strategy focused on preventing the introduction of disease-causing agents into an area where they do not currently exist. This can include practices such as sanitizing equipment, controlling movement of animals and plants, and implementing quarantine measures. By keeping pathogens out of healthy populations, farmers can effectively reduce the chances of an outbreak.

Eradication involves completely eliminating a specific disease from a population or a geographic area. This can be achieved through various methods, including the removal of infected plants or animals and strict control measures to prevent the spread of the disease. By removing the source of infection and breaking the cycle of disease transmission, eradication can lead to a long-term resolution of a pest or disease problem.

These three concepts – genetic resistance, exclusion, and eradication – form a robust strategy for controlling diseases sustainably,
