Downy mildew is caused by a group of fungi, including Peronospora, Pseudoperonospora, and Plasmopara. These fungi thrive in humid environments and can spread quickly through water droplets, wind, and contact with infected plants. Overwatering, poor air circulation, and high humidity create an ideal environment for downy mildew to develop.

In addition to these environmental factors, downy mildew can also be caused by:

• Poor soil quality
• Weak or stressed plants
• Inadequate light
• High temperatures
• Contaminated potting mix or tools

Symptoms of Downy Mildew on Plants

The symptoms of downy mildew can vary depending on the type of plant and the severity of the infection. However, common signs include:

• Yellowing or chlorotic leaves
• White, cottony growth on the underside of leaves
• Black spots or patches on the leaves
• Stunted growth
