Latin name: Cochliobolus miyabeanus (1to et Kubibay) Drechsler ct Dastur is a symptom of damage: Flax can occur in the entire growth period of rice. The germinating period of the seed germinates the victim and becomes brown, and the heavy person is dead. The rice plants were most commonly affected by leaves, and scattered mainly on the leaves with many spots such as sesame size. The center of the lesion is gray-brown to gray-white with brown edges and yellow halos around it. There are no necrotic lines on both sides of the lesion. This is an important difference from rice blast disease. In severe cases, the lesions merge into irregular large bones. Lesions, diseased leaves from the tips of the leaves gradually dry, and even the whole plant withered, susceptible varieties, the leaves will produce irregular acute large lesions, dense layer of dark brown mold layer above (that is, the germination of the bacteria Spores and conidia). Spike neck victim, brown or gray-brown, causing ear dry. The difference with the panicle-necked pheasant: the color of the panicle-necked pheasant is darker than the flamingo, and is dark-brown and gray-brown afterwards; the discolored part is shorter than the flax patch, the flax patch is tan, and the disease can grow long. Up to 7 to 8 centimeters. It is also possible to cut the diseased part for moisturizing culture. - After a day and a night, the rice seedlings can be seen in the diseased part of the gray green mold layer, and the flax spots need to grow conidia after 2 days. Early grain damage, the whole grain turned gray and black, resulting in the valley, when the humidity is high, dark brown mold. The morphological characteristics of pathogens: Conidial stems often 2-4 bunches, dark brown base, with multiple mold septum; the incidence of heavier in paddy fields. Varieties have different disease resistance. The pathogenic requirements for temperature and humidity are not strict. At a temperature of 25-30°C, as long as there is a short time of water droplets or saturated humidity, the germination and infection of conidia can be satisfied. Natural hosts see weeds such as avocados, crickets, crickets and other weeds. Characteristics of the disease: The pathogens used hyphae and conidia to overwinter on diseased and diseased rice straw. The conidia on the straw the following year spread to the fields of Putian and Daejeon through the wind and were invaded by epidermis or stomata of the seedlings. Sowing the diseased valley, the mycelium lurking on the chaff can directly invade the seedlings. During the entire growth period of the rice, a large number of conidia formed on the diseased plants can be repeatedly infected. The incidence of general fertilizer shortage, potassium deficiency, soil barrenness, sandy soil, acid soil and long-term plots of water is heavier. The temperature and humidity requirements of the bacteria are not strict. At a temperature of 25-30°C, as long as there is a short time of water droplets or saturated humidity, the germination and dissemination of conidia can be satisfied. Control methods: 1, with strong chlorine or 80% "402" soaking, the same method with rice blast. 2, strengthen fertilizer and water management. More organic fertilizer should be applied to sandy soil, and lime can be applied to acidic soil. Nitrogen growth in seedlings needs nitrogenous fertilizer, potash fertilizer or human waste, grass ash, etc. In terms of irrigation, it is necessary to avoid deep-water irrigation and long-term accumulation of water, and to prevent drought-induced leaf spot of flax.
