    Black spot is a disease that can occur during the whole period of sweet potato growth, and it will mainly damage the roots of seedlings in the early stage of growth, so that the roots will appear black lesions. When growing to the middle stage and storage, black lesions will form on the surface of the potato pieces, so that the inside of the potato flesh will appear jet black, and the sweet potatoes at this time can not be eaten in large quantities, not only difficult to remove, but also have a faint bitter and astringent taste.

    Potato tubers with pathogens are the main cause of the formation of black spot disease, so when raising seedlings, it is necessary to choose potato seeds with good disease-free and injury-free resistance, disinfect the potato seeds before sowing, and remove the bacteria contained in the potato seeds through drugs. Secondly, it should also be noted that diseased soil is also one of the causes of black spot disease, and the temperature suitable for the survival of the disease is about 25 degrees, so the land can be renovated to reduce the occurrence of germs through exposure to the sun, and at the same time, it is necessary to avoid non-continuous cropping. For planting land that has already developed disease, we can choose to change the structure of the soil by crop rotation and reduce the survival rate of the disease.

    For sweet potatoes with black spots, if the surface area of the black spots is not large, we can dig out the black spots, and the rest is edible, if it occupies a large area, don't eat it, it will have an impact on the body. Hope mine is helpful to you!
