Best Fungicide For Septoria Leaf Spot
Introduction
I’ve gardened in many regions of the country, and I’ve lost crops to septoria leaf spot in every single one. That’s because this tomato disease is devastatingly widespread—and historically difficult to control. But you can beat it if you know how. Here are my top tips for preventing and treating septoria leaf spot on tomatoes—with a few bonus suggestions for fighting off other common tomato diseases, too.
Introduction
Septoria leaf spot is a fungal disease that affects tomatoes, peppers, eggplants and other members of the Solanaceae family. It can be difficult to control because it’s often confused with other tomato diseases such as early blight or late blight. The first symptoms are small brown spots on leaves that will eventually grow larger and turn yellow. Eventually these spots turn black in color and form concentric rings around them, much like an onion would have if cut in half horizontally. These dark lesions then become sunken into the leaf tissue before they eventually fall away from the plant completely revealing greenish-brown patches where they once were. The entire process takes about two weeks after symptoms appear so you’ll need to watch closely for them when growing tomatoes outdoors during this time period each year – especially towards summer’s end since this is when septoria-infected plants often experience highest yield loss due to infection rates rising exponentially with increased temperatures!
Septoria leaf spot is a common tomato disease.
Septoria leaf spot is a common tomato disease. It is caused by the fungus Septoria lycopersici, which is spread by wind and rain, and attacks tomatoes and eggplants. The fungus can survive on dead leaves from previous seasons, so it’s important to remove those in order to prevent another outbreak. While septoria leaf spot isn’t very serious for tomato plants, it can reduce yields significantly if left untreated.
Symptoms of septoria leaf spot
Septoria leaf spot is a plant disease caused by the fungus Septoria musiva. It is one of the most common fungal diseases on tomato plants and can also affect peppers, eggplant and other vegetables. While symptoms vary slightly depending on the host plant (i.e., tomato vs. pepper), all plants infected with septoria leaf spot exhibit similar signs:
- Brown-black spots on leaves
- Brown-black spots on fruit
- Brown-black spots on stems
Causes & life cycle
Septoria leaf spot is caused by the fungus Septoria lycopersici. In addition to causing disease on tomato plants, the fungus can infect other plants in the Solanaceae family such as eggplant and pepper.
This disease can be spread by wind, rain and insects. It can also be spread from infected plants to healthy plants if you do not follow proper cultural practices such as rotation or sanitation (removal of diseased plant debris).
Preventing septoria leaf spot in tomatoes
Preventing septoria leaf spot in tomatoes is all about timing. The first step is to be aware of the risk of septoria leaf spot disease and its severity in your area. Next, check the weather conditions before planting so that you can select a plant variety that will be most resistant to disease based on your region’s growing season.
When choosing where to plant tomatoes, remember: good drainage and sun are key! Well-drained soil prevents waterlogging which may lead to septoria leaf spot disease, while sunlight helps tomatoes grow strong enough to fight off infection. If these factors aren’t possible due to climate or growing conditions, consider using raised beds or containers instead of planting directly into the ground where there will likely be excess moisture from rainfall or dewfall during certain times of year when it rains for long periods at night (which promotes fungal growth).
Treating septoria leaf spot in tomatoes
If you have tomato plants affected by septoria leaf spot, the most effective way of treating this disease is to spray the plant with a fungicide. Treating your plants at the first sign of disease will help prevent future problems from developing. It’s important that you spray your plants early in the day so that the sun doesn’t bleach out any potential fungicides before they can work their magic. Fungicides should be applied when temperatures are below 85 degrees, and humidity levels should be below 80%.
You don’t have to deal with septoria this year (just try these tips).
There are plenty of ways to avoid Septoria Leaf Spot in your greenhouse. You can avoid planting in areas with previous septoria infection, use a fungicide, use a resistant variety, and even use crop rotation! The choice is yours!
- Avoiding the problem altogether is the best thing you can do for your plants and yourself. If you spot Septoria Leaf Spot on your plant and want to prevent it from spreading any further (or if you’re just feeling like prevention is part of your job), there are several different ways that we recommend:
