Occurrence and Control of Vegetable Anthracnose
Symptoms mainly occur in leaves, petioles, and veins. The lesions on the leaves were small and round, with a pale, watery appearance at the beginning, followed by grayish-brown, brownish edges, and slightly uplifted. The center of the lesion is grayish white, extremely thin, translucent, and easy to perforate. The lesions on the veins often occur with the back of the leaves, with brown stripes. Petiole lesions are oval or spindle-shaped, brown. When the leaves are seriously damaged, the number of lesions can reach more than a hundred, and the mutual convergence can cause the leaves to fall early. When wet, the diseased area may produce pale red sticky material. The onset of the disease mainly occurs when the mycelium is overwintering in the diseased plant residue, and the conidia can also be overwintered on the seed. The dormant mycelium forms conidia during the growing season and is washed by rainwater or splattered onto nearby vegetable strains and invades directly from the host epidermis. Conidia are produced on the diseased spot to re-infect. The bacteria prefers high temperature and humidity, and the temperature of 26-30°C is the optimum temperature. Usually the seeds are sown early, the temperature is high, the rain is poor, the varieties are poor in resistance, the terrain is low, and the incidence is heavy when planting dense. Control methods 1. Pay attention to crop rotation, clean the garden after harvest, and plunge the soil. 2. Seed soaking in warm water of 55°C for 5 minutes before seeding. 3, timely spraying at the beginning of the disease, available 65% mancozeb 600 times, 70% thiophanate-methyl 800 times, 70% chlorothalonil 1000 times, 50% carbendazim 1000 times and other control.
