What is the best way to prevent fungal growth on my tomato plants?

I recently planted tomato plants in my garden, but I noticed some fungal growth on the stems. What can I do to prevent this from spreading to the rest of the plant?

Fungal growth on tomato plants is often caused by lack of air circulation. Make sure your plants have enough space between them and prune any excess foliage.

You can also try using a natural fungicide such as neem oil or a mixture of baking soda and water to prevent fungal growth on your tomato plants.

Avoid overhead watering and try drip irrigation instead to reduce moisture on the leaves, which can contribute to fungal growth.
