|I have new plants (3 varieties) planted in an area that gets morning sun. All have brown spots on leaves just in the past few days. Should I use fungicide (we had a lot of rain last week)?

|Because you've had a lot of rain, a fungal disease is probably the cause of the spots on your tomato plants. Copper or sulfur sprays can prevent further development of the fungus. The biofungicide Serenade can lessen the problem. There are lots of other fungicides available for tomato plants. Just be sure to apply according to label directions. Hope your plants recover soon!
