Watermelon anthrax
Watermelon anthracnose can occur during the whole growth period, but the most serious occurs in the middle and late stages of plant growth, resulting in dead leaves and fruit rot. In the onset of seedlings, round brown lesions appeared on the cotyledons, and the base of the young stems developed into dark brown, contracted, and even collapsed. At the onset of adulthood, a roundish yellowish spot appears on the leaf, followed by a brownish color, brownish-brown edges, and pale brown in the middle, with concentric ring patterns. After the lesions expand and merge with each other, it is easy to cause perforation of the leaves. In the immature fruit, the initial lesion appeared water-soaked, with a pale green round spot. On the mature fruit, it began to be a prominent lesion. In the later period, it expanded into a brown depression. Many small black spots were arranged in a circle, and when it was wet, a pink sticky was produced. Objects, mostly malformed or black rot.
