Q&A - Will fungicide cause sunburn on a tomato plant?
Question:
Can you spray fungicide on your tomatoes while the sun is shining on them? I would be afraid of sun burn to the plants.
Answer:
If you need to worry about sun burn depends on the kind of fungicide you are using. Master Gardener Tom Mashour uses neem oil which will cause sun burn on tomatoes if applied in the sun. Neem oil should be applied when the sun is low in the sky. He applies it late in the evening when the sun is setting. The fungicide label should let you know if you need to take precautions.
