Symptoms: From seedling to maturity can be affected. It mainly damages stems and pods, but also leaves or petioles. The stem is infected with primary brown spots, which are densely covered with black dots arranged irregularly. The infected pods are arranged in a circular pattern with small black spots, and the infected pods cannot develop normally. The seedling stage Ziji disease is black brown disease spot, the edge is slightly shallow, the disease spot often appears cracking or depression after expansion; the disease spot can extend from the cotyledon to the young stem, and the diseased part is dead. The infected leaf margins are dark brown and the interior is light brown. Petiole infected spots brown, irregular.
Control methods: (1) Select disease-resistant varieties and disease-free seeds. (2)After harvest, the sick and disabled bodies should be removed in time, deep ploughing should be carried out, and rotation should be carried out for more than 3 years. (3)medicament
Control: seed dressing with 50% carbendazim WP or 50% iprohydantoin WP 0.5% of seed weight before sowing, stirring and suffocating for several hours. After flowering, spray 500 times solution of 25% Tanteling WP or 600 times solution of 47% Garinon WP.

Occurrence and control techniques of soybean anthracnose
The main results are as follows: (1) most of the diseased seeds with disease symptoms die in the soil before emergence and can occur from seedling stage to mature stage. The pathogen can invade young stems from cotyledons, harming stems and pods, as well as leaves or petioles. 1.1 Cotyledon disease symptoms can occur from seedling stage to mature stage, there are dark brown disease spots on the emergence cotyledons, the edge is slightly light, the disease spot expansion often appears cracking or depression, when the climate is humid, the cotyledons become water-immersed, wilt and fall off quickly. 1.2 symptoms of leaf disease infection on the leaf, irregular spot and deep edge
