How does excessive irrigation affect plant health?

Excessive irrigation can create conditions that are conducive to the spread of fungi. When soil is overly saturated with water, it can lead to a reduction in oxygen availability for the roots, creating a stress situation for the plant. This wet environment is favorable for fungal pathogens, which thrive in moist conditions. The increased moisture can also lead to root rot and other fungal diseases, as pathogens have the right conditions to multiply and infect plant tissues.

Understanding this relationship between water management and disease prevention is crucial for maintaining healthy plants. The promotion of fungal growth due to excessive moisture highlights the need for balanced irrigation practices that ensure adequate water supply without creating overly wet conditions that compromise plant health.
