Which of the following environmental conditions does downy mildew thrive in?

Downy mildew thrives in cool, wet weather conditions. This fungal disease prefers environments with high humidity and moisture, typically developing during periods of cool temperatures and excess moisture in the air or on plant surfaces. The spores of downy mildew require water to germinate, and the cool temperatures help ensure that the host plants remain susceptible to the infection.

In contrast, hot, dry weather and low humidity create an environment that is less conducive to the growth and spread of downy mildew. Warm weather can promote different fungal diseases, but it is not the ideal condition for downy mildew, which specifically flourishes in the cooler, moist environments. Understanding these environmental preferences is crucial for effective disease management and prevention in agricultural practices.
