Here are some ways to treat tomato blights:
- Use a copper or sulphur based fungicidal spray to treat the tomato plants. Spray the leaves until they are dripping wet.
- Use a baking soda spray. These sprays are good for killing fungi such as blight and are a bit more environment-friendly.
Besides, what causes blight on a tomato plant?
Tomato blight, in its different forms, is a disease that attacks a plant’s foliage, stems, and even fruit. Early blight (one form of tomato blight) is caused by a fungus, Alternaria solani, which over-winters in the soil and infected plants. Affected plants underproduce. Leaves may drop, leaving fruit open to sunscald.
Similarly, does baking soda kill tomato blight? Baking soda has fungicidal properties that can stop or reduce the spread of early and late tomato blight. Baking soda sprays typically contain about 1 teaspoon baking soda dissolved into 1 quart of warm water. Adding a drop of liquid dish soap or 2 1/2 tablespoons vegetable oil helps the solution stick to your plant.

What is the difference between early and late blight?
Here’s the biggest difference: Late blight is caused by the pathogen Phytophthora infestans, while early blight is caused by Alternaria solani. Phytophthora infestans is an oomycete, a fungus-like eukaryotic microorganism. solani. It also kills all infected material, causing dark, watery spots to form.
