Common diseases in crop planting

Bean rust: This pest often occurs when crops are planted, and it is an air-borne disease, which spreads very fast, so it is extremely harmful to crops, and a large number of disease spots will be produced on the leaves after the disease occurs.

Early blight: tomato, pepper, eggplant, etc. Usually infected by this pest. After the onset, the leaves are most seriously damaged and light gray spots will be produced. When the humidity is high, black mold will appear.

Main pests of cultivated crops

Corn beetle: After crops are infected with this pest, the larvae will suck the leaves, which will cause the leaves to dry up and die. In more serious cases, there will be dozens of larvae on the leaves, which will do great harm to the plants.

Straw fly: after infection, larvae will do harm to stems and leaves, resulting in dry and rotten stems and leaves. After infection, wheat will cause white ears and rotten ears, resulting in its inability to bear fruit.
