How to Control Anthrax Anthracnose
Disease occurs on leaves and shoots. The lesions on the leaves are elliptical or round, ranging in size from 3 mm to 12 mm. The lesions have narrow dark brown bulges on the edge of the lesion and the center is grayish white, with thick round or oval black dots formed at the gray and white areas later in the lesion. Sparse, sparsely arranged, mostly on the front of leaves, sometimes arranged in rotenia, the conidia of pathogenic bacteria. On the young shoots, the lesions are strips and greyish-white, with black spots on them, which can also cause the branches to die. This disease often occurs in combination with the brown leaf spot of Euonymus japonicus. There are two kinds of lesions in the same leaf. The difference between this disease and the brown leaf spot of Cyclovirobuxine is that there is no yellow halo around the lesion, but the edge of the brown spot Halo circle. The pathogenic genus is a semi-cognitive fungus of the subphylum Ceratocystis. The conidia are located under the epidermis and break through the epidermis after maturity. Conidiophores do not branch, colorless.
The law of incidence
The pathogenic bacteria overwintered in diseased and diseased leaves with mycelium or spore disks. In May and June of the following year, when the temperature and humidity are appropriate, the conidia germinate and invade the host wound. The parasitic disease is not strong and can only be invaded from the wound. The disease occurs later than the brown spot disease. In the rainy season, the humidity is high, the temperature is high, and the hygiene is poor. It often occurs more severely.
Control methods
Remove the source of infection in autumn and winter to collect diseased branches and leaves to burn and reduce the source of disease.
The prevention and control of gardening technology will improve the conditions for ventilation and light transmission, strengthen cultivation and management, and promote robust plant growth and increase resistance to disease. Low-lying land should be well drained to prevent accumulation of water.
At the early stage of chemical attack, 70% thiophanate-methyl 1000 times, 50% carbendazim WP 1000 times, or 75% chlorothalonil wettable powder 500 times, or 50% tetromycin Wet powder 800 times and so on. Spraying once every 10 days or so, for 3 to 4 consecutive times, can achieve significant results.
