Description

technical field [0001] The invention relates to the technical field of preventing and controlling diseases and insect pests, in particular to a natural fungicide for preventing and controlling edible lily anthracnose. Background technique [0002] Anthracnose belongs to the fungus Deuteromycotina subphylum, Nigellales, Anthracnose, Brassica anthracnose, and is an important pest in vegetable production. Lesions mostly occur on the back ribs, petioles and stems of leaves, with few leaves, and can occasionally infect inflorescences and seed pods. Lesions are spinous or oval, brown and sunken, and when severe, the lesion heals and the leaves die. [0003] Edible lily anthracnose mainly affects the leaves, and also affects the stems when it is severe. When the leaves are infected, water-soaked dark green dots appear at the initial stage, and later develop into nearly round to oval gray-white to yellow-brown necrotic spots, with light yellow halos on the edges. Spore tray. The...
