What does the term 'resistant varieties' imply in crop production?

The term 'resistant varieties' in crop production refers to the notion that while certain plant varieties possess traits that help them withstand or tolerate specific diseases or pests, this does not mean they are entirely immune to all threats. Resistance typically means that the plant can survive or continue to grow despite the presence of certain pathogens or stressors, but it is still susceptible to some degree of infection or damage. This distinction is crucial for understanding plant health management strategies, as resistant varieties can greatly reduce the need for chemical treatments, but they do not eliminate the risk of disease or pest impact entirely. It's important for growers to recognize this when selecting crop varieties and managing their production systems.
