Septoria Leaf Spot (Tomatoes)

Description: The most destructive of all tomato problems

Small brown spots appear on bottom leaves first. Leaves gradually turn yellow and die as the disease works its way upwards. Premature death of vine significantly reduces tomato production.

Solution: Use Soap-Shield Fungicidal Soap or Copper Dust starting after setting out plants, then every 7-10 days. Apply more frequently if disease is increasing rapidly. Reapply after rain. Weed Barrier Mats also help by keeping fungi in the soil from splashing on leaves during rains.

Try a foliar spray of Liquid Kelp from the time plants are set out to improve plant vigor. If possible, use drip irrigation to avoid wetting leaves.
