Can I use a fungicide on my greenbrier?

You can, but it is better to fix the environment first. Removing the infected leaves is usually enough.

Are these spots contagious to other plants?

If it is a fungal issue, it can spread through water splashes. Keep the infected plant away from others until it is clear.

Likely causes

Fungal Leaf Spot
Possible
How to tell: Small, dark, or circular spots appear on the leaves, sometimes with a yellow halo around them.
What to do: Remove the affected leaves immediately to stop the spread. Improve air circulation around the plant and avoid getting water on the foliage when you irrigate.
Sunburn
Possible
How to tell: Bleached, white, or brown scorched patches appear on the leaves that face the strongest sun.
What to do: Provide some shade during the hottest part of the afternoon. If the plant is in a very intense window, use a sheer curtain to filter the light.
