Why do farmers spray water on plants before an overnight freeze?

Is it OK to water plants at night in summer?
Watering at night is not the best for your plants’ leaves or overall health. Here’s why. After a night time soak, leaves can stay wet for a pretty long time since they don’t have the day’s sun to dry them off. Because of this, damp leaves become extra vulnerable to fungal development.
