Tomato blight is caused by a fungus called Phytophthora infestans. It spreads via airborne spores . This particular type of fungus requires poor airflow and hot humid conditions to flourish.
This of course begs the inquiry “Can Tomatoes get blight?”
Here is what my research found. tomato blight can affect other plants , too, such as potatoes and eggplants. It is also important to note that two types of fungi are responsible for causing blight in any plant, namely, Alternaria emetophilia and Alternaria solani.
One way to consider this is it is vital that gardeners understand late blight isn’t like any other tomato and potato diseases . You will see pale green, water-soaked spots on the leaves, and these quickly turn into dark spots. Additionally, stems also turn black.
How do you get tomato blight?
Time to act. Tomato blight, a fungal infection called Phytophthora infestans, spreads by wind and water-splash. It also attacks potatoes and is triggered by warm, wet conditions, making outdoor tomatoes more susceptible than those in a greenhouse .
Another thing we wanted the answer to was; how do you get rid of late blight on Tomatoes?
In its earliest stages, late blight can be mistaken for other foliar diseases, such as Septoria leaf spot or early blight, but as the disease progresses there can be no mistaking it as late blight will decimate the tomato plant. If the plant appears to be extensively affected with late blight, it should be removed and burned , if possible.
Another query we ran across in our research was “How do you get rid of nightshade blight on Tomatoes?”.
An answer is that remove all vegetation from the tomato garden bed and other suspected garden areas at the end of the growing season after you detect blight in tomatoes, potatoes or other nightshade plants. Dig into the soil to uproot the entire plant, and pick up pieces of broken stems, fallen tomatoes and other plant parts.
Can tomato blight affect other plants?
The infection can survive as long as the plant tissue is alive. Tomato blight can affect other plants, too, such as potatoes and eggplants . It is also important to note that two types of fungi are responsible for causing blight in any plant, namely, Alternaria emetophilia and Alternaria solani.
Many tomato cultivars exhibit some resistance to early blight. However, resistance is not the same thing as immunity . Regardless of the cultivar that you have selected, your plants can still be infected with early blight if you do not take precautions to prevent the disease.
Some articles claimed don’t put the affected plant in the compost pile, as it will continue to spread infection. At this time, there are no tomato varieties resistant to late blight. Late blight can also infect potato crops , so keep an eye on them as well. Weather is a major factor as to if tomatoes will get late blight.
What causes spots on tomato plants?
Early Blight Early blight can be caused by either one of the fungi types, Alternaria Tomatophilia and Alternaria Solani. This blight resembles rings and presents first on the leaves and quickly progresses to the plant stem. The spots also show on the tomato, soon developing into large bruises .
One of the next things we wondered was; what is wrong with my tomato plants?
Here is what I discovered. early blight is a common tomato disease caused by the fungus Alternaria solani. It can affect almost all parts of the tomato plants, including the leaves, stems, and fruits. The plants may not die, but they will be weakened and will set fewer tomatoes than normal.
