Tips for Preventing Leaf Spot

While choosing resistant tomato varieties is important for preventing leaf spot, there are other steps you can take to minimize the risk of the disease in your garden. Here are some tips:

Avoid planting tomatoes in humid or wet conditions, as this can promote the growth of fungi.

Ensure that your plants have adequate air circulation, as this can help reduce the risk of disease.

Water your plants at the base rather than from above, as this can help prevent the leaves from becoming wet.

Remove any infected leaves or plants from your garden to prevent the disease from spreading.

Apply a fungicide to your plants if necessary, but be sure to follow the instructions carefully.

By choosing resistant tomato varieties and taking steps to prevent the growth of fungi in your garden, you can help ensure that your tomato plants stay healthy and productive throughout the growing season.
