Oat leaf blight
Symptoms mainly affect the leaves, leaves, sheaths, and other shoots. The leaves were infected with 1-20.5-1 mm (mm), and the yellow-to-brown lesions with indistinct edges were found. Afterwards, they were enlarged to 5-202-3 (mm), brown in the middle and slightly yellow around. For a long time, the lesion gradually withered from the tip of the leaf. The disease starts from the lower leaves and gradually expands upwards. Leaf sheath disease is similar to leaf disease.
