Early blight is a disease that puts at risk the cultivation of the tomato plant as few, given that it can appear at any stage of its growth and affect all its air organs , from its stem to its leaves and, of course, its fruits. Is a danger that farmers must keep in mind and fight throughout development.
Its symptoms begin to manifest in the oldest leaves, where you can see brown lesions of small size and irregular shapes, formed from a series of concentric rings, which appear as a result of the struggle of the plant to stop the infection . The lesions are usually surrounded by a yellow region, given the emergence of toxins; if they are generated in very high numbers, they can be united to cause the destruction of the leaf tissue, something that negatively affects even the quality of the fruit, since it leaves it unprotected against the sun.
He Phytophthora infestans , meanwhile, generates the late blight . It is a plague which can destroy tomatoes, potatoes and other crops that are destined for human consumption.
This disease is one of those that cause the greatest destruction to plants, partly because of their speed to travel through the air, but also because of their great reproductive capacity and the characteristics of the fungus that generates it, of an important virulence . In addition, almost no aerial tissue of a plant affected by late blight is likely to escape its effects.
With respect to symptom of late blight, one of the most obvious is the appearance of spots of various sizes on its surface, which vary according to the surrounding conditions. First, the lesions exhibit a dark green color, with white filaments at their margins due to moisture. After a while, the green turns brown, and the lesions can reach the entire leaf blade, stripping it of its stiffness, thereby expiring the petiole. Branches and stems can suffer the same fate. In fruits, it is common to appear reddish brown spots that cover almost its entire surface.

Therefore a development "To rope and blight" It combines both modalities.
