What happens to the rate of infection in plants during critical life stages?

The correct answer highlights that the rate of infection in plants can escalate under favorable conditions. During critical life stages, such as germination, flowering, or fruiting, plants are often more susceptible to pathogens. Favorable environmental conditions—like optimal temperature, humidity, and soil moisture—can create an ideal environment for pathogens to thrive and multiply.

For example, if conditions are warm and moist, fungal spores may germinate more readily, and the rate of infection can increase significantly. Furthermore, during these sensitive periods, the plant's defenses may be lowered, making it easier for pathogens to infect and propagate. This dynamic interplay between environmental factors and plant physiology underscores the importance of understanding how conditions can influence pathogen pressure and disease development at particular stages of plant growth.
