What is the best treatment for tomato blight?
Treating Blight
If blight has already spread to more than just a few plant leaves, apply Daconil® Fungicide Ready-To-Use, which kills fungal spores and keeps blight from causing further damage.
How do you control blight disease?
Measures for controlling and preventing blights typically involve the destruction of the infected plant parts; use of disease-free seed or stock and resistant varieties; crop rotation; pruning and spacing of plants for better air circulation; controlling pests that carry the fungus from plant to plant; avoidance of ...
Does blight stay in soil?
Blight cannot survive in soil or fully composted plant material. It over-winters in living plant material and is spread on the wind the following year. The most common way to allow blight to remain in your garden is through 'volunteer potatoes'.
How is late blight spread?

What is the difference between early blight and late blight?
Early Blight: dark, sunken lesions at or above the soil line, sometimes called collar rot. Late Blight: black and brown lesions appear on stem and petioles; when petioles or leaf stalks are affected, entire leaf can collapse; entire vine or plant can quickly collapse and die in period of high humidity.
Does baking soda kill blight?
Baking soda has fungicidal properties that can stop or reduce the spread of early and late tomato blight. Baking soda sprays typically contain about 1 teaspoon baking soda dissolved into 1 quart of warm water.

How do you kill blight in soil?
One method that has proven effective and environmentally friendly is solarization -- using the sun's light to heat the soil high enough to kill the blight-producing bacteria.
How do you get rid of blight in soil?
Aggressively remove the infected leaves and purge them from your property. Do not add the material to your compost pile, and dispose of it in the trash, away from your garden. Simply removing infected plant matter will not control early or late blight. You will need to use fungicides to manage these infections.
