The harm of loquat anthracnose: loquat anthracnose is a fungal disease, which can harm loquat leaves, fruits and seedlings. When anthracnose harms loquat seedlings, it will cause a large number of seedling leaves to die and fall off, and when serious, the whole seedling will die. When the leaves of loquat trees are damaged by anthracnose, they will form round to nearly round leaf spots, which are gray-white in the center, dark brown at the edges, 3-7 mm in diameter, and can heal into large spots after expansion. After the loquat fruit is damaged by anthracnose, round, light brown, water-stained spots will be formed on the fruit, and the disease spots will be sunken in the later stage, and there will be pink clay particles in the disease part, which is the conidia of the pathogen. And the spot of anthrax expands rapidly in the later stage, which often causes the whole fruit to turn brown and rot, or the diseased fruit shrinks into a stiff fruit. Prevention and control methods of loquat anthracnose: method 1. When selecting garden plots, priority should be given to the land with high and dry terrain, and ditching and drainage should be done well in the garden. Method 2.
