The prevention and control of anthracnose

Anthracnose is a fungal disease that can harm the leaves, fruits, and seedlings of alfalfa, and mainly affects the fruits. At the beginning of the fruit, a light brown immersed round spot forms on the surface of the fruit, which turns dark brown to a dark brown round or oval lesion. The diseased area is sunk, the dense reddish dots appear, and the later black spots are arranged in a concentric ring pattern. Shaped, the fruit is soft rot and finally shrinks into a stiff fruit. Leaf lesions are often sudden, grey-brown, and the surface of the diseased part is sunken. Shoots and shoots will also have similar lesions, and the shoots will wither. The grafted seedlings are in rapid onset and the diseased seedlings quickly wither.
Control methods: 1 Select high-dry ground in the garden, and open drain in the garden. Remove diseased leaves, fruit and burn them. The ward is limed and spread on the ground; 2 spray 0.5% Bordeaux or 50% thiophanate 500-600 times to prevent and control.
