Choosing a resistant variety of a plant is a method of what?

Choosing a resistant variety of a plant is a method of plant disease prevention because it focuses on utilizing varieties that have been bred or selected for their ability to withstand specific diseases or pests. By selecting resistance traits in the breeding process, growers can significantly reduce the incidence and severity of diseases, leading to healthier plants and reduced need for chemical interventions like pesticides.

Resistant varieties can have specific resistances to fungal, bacterial, or viral infections, which allows them to survive and thrive even in the presence of pathogens that would otherwise harm susceptible varieties. This proactive approach not only maintains crop health but can also contribute to higher yields and sustainability in agricultural practices, minimizing reliance on chemical disease controls.
