In contrast, late blight starts with small water-soaked areas that rapidly enlarge into purple-brown oily-looking blotches on the leaves. Early blight generally causes small brown-black spots on the lower leaves that spread upwards as the disease progresses. ![]() To effectively treat tomato blight, it is crucial to identify the disease correctly by noting its symptoms carefully. Brown or tan spots on upper leaves: In late blight cases, these discolored areas often form on top foliage and are surrounded by a light green or yellow halo.īy recognizing these symptoms early, gardeners can take appropriate steps to treat and manage tomato blight in their plants effectively.Rapidly spreading watery rot: A distinct symptom where affected leaves quickly collapse, shrivel up, and turn brown as the disease advances.Dark spots on older foliage: These spots initially appear near the soil line and can be an early sign of blight progression.Small, brown lesions on bottom leaves: Early blight usually begins with a few tiny, discolored marks on older foliage near the ground.Large, blotchy leaf lesions: Early indications of blight can include light green or water-soaked spots on leaves, which may grow larger over time.Wilting petioles: One of the initial symptoms, characterized by weak or drooping stems connecting leaves to the main plant.Here are some key signs to look for when diagnosing tomato blight: It is crucial for gardeners to accurately identify the symptoms of tomato blight in order to treat and prevent the disease from spreading. Identifying the symptoms of tomato blight, such as brown spots on leaves and fruit, is crucial for early intervention. To avoid such scenarios, it’s crucial to remove all infected plant debris from your garden space and dispose of them properly rather than using them as compost material. As the compost degrades and becomes part of the soil mix used for planting new tomato crops, it inadvertently introduces fungal spores from previous infections into your garden beds. ![]() ![]() One common example is when infected garden waste finds its way into a compost pile. In some cases, contaminated gardening tools or soil can also contribute to the onset of this disease. These microorganisms can be spread through various means, such as wind, insects, and animals. Tomato blight is primarily caused by fungus-like organisms that thrive in damp, warm weather conditions. It begins as small circular spots on lower leaves that eventually coalesce into larger dead zones surrounded by yellow halos. Lastly, Septoria leaf spot (caused by Septoria lycopersici) tends to be less severe than its counterparts but still requires attention for a bountiful harvest. This type of blight appears suddenly as it spreads rapidly under favorable conditions like cool temperatures and high humidity levels. Late blight, responsible for the infamous Irish Potato Famine in the 1840s and caused by Phytophthora infestans, can affect both tomatoes and potatoes with devastating results if left unchecked. Each type is caused by a different fungus but presents similar symptoms, making them somewhat challenging to distinguish from one another.Įarly blight, caused by the fungus Alternaria solani, typically affects older leaves near the base of the tomato plant first before spreading upward. There are three main types of tomato blight that plague gardeners and their beloved plants: early blight, late blight, and Septoria leaf spot. ![]() Tomato blight is a fungal disease that affects tomato plants and can cause significant damage to crops if left untreated, with two main types being early blight and late blight.
