What is a key consideration for using resistant varieties?

Choosing resistant varieties as a management strategy for pests and diseases is important, but one of the most crucial factors to keep in mind is that resistance may not provide complete protection. While resistant varieties can significantly reduce the incidence of pest attacks or disease outbreaks, it is important to recognize that they do not make plants invulnerable. Some pests may overcome these resistances over time, and certain environmental factors can impact the effectiveness of resistance.

This understanding emphasizes the importance of an integrated pest management approach, where resistance is one part of a broader strategy that includes monitoring, cultural practices, and judicious use of pesticides. This holistic approach helps ensure that crops can be protected while recognizing the limitations of resistance. By acknowledging that resistance can offer a level of protection but may not eliminate the risk entirely, practitioners can make more informed decisions about how to manage pests and diseases effectively.
