Virulosis, tea scutellaria, and hormonal phytotoxicity occur frequently in vegetables. Because the symptoms of the three are similar, they are often misidentified and missed the opportunity for prevention and treatment. The specific identification method has three symptoms.
The dwarfing of the mosaic plants was not obvious, and the chlorotic spots and round spots appeared in the upper leaves. The lesions were limited by the veins and were mostly triangular and eventually brown. Dark green and light green and white patches or lines appear on the leaves.
The growing leaves of fern leaves or loquat leaves develop into slender lobule. The lobule is later thinned or even leaves no leaves. It leaves only veins and finally spirals down, commonly known as “chicken claw leafâ€.
Staphylococcus aureus had pale, pale yellow necrotic mottled or irregular striae and stripes on the lower leaves and fruit. Because of its small body size, the tea plant is often mistaken for viral diseases and hormone harm. After extracting the leaf liquid from the tea plant, the leaves become hard, brittle, and the leaf meat thickens and the young shoots become distorted. The back of the leaves shows an oily luster or oily tinge, which turns yellow-brown or gray-brown. Hormonal injury is caused by excessive use of hormones, the growth point of the leaf is downwardly curled, slender, and the leaf margin is distorted, but the back of the hormone harmed by the hormone is not greasy, nor is it brownish, and the leaf blade is stiff and thick. And generally a large area occurs at the same time.
