Occurrence characteristics of wheat leaf blight

Chinese name: cedar mildew in wheat Latin name: Gerlachia nivalis (Ces.at Sacc.) Gams. andMull. Sexual stage: Monographeila nivalis (Schaffn.) Mull Symptoms: Wheat seedlings occur before they mature. All parts of the wheat plant can be affected, but the effects of leaf blight, sheath blight, and ear rot caused by the late growth period are the greatest. Before the jointing of wheat, only the outer layers of the plants buried in the soil became brown and the aboveground parts were asymptomatic. After the jointing, the leaf sheath near the surface began to turn brown, and about ten centimeters of lesions appeared around the mouth of the ground, with obvious edges. When the temperature is high and the humidity is high, the lesions are enlarged and appear dark green with water immersion, and then become brown, often forming several layers of different shades of color, but not obvious rim spots. The lesion is oval or nearly elliptical. When the weather is wet, there are often shallow brick red molds in the middle of the lesions, namely the conidia and conidia of the pathogen. At the leading edge of lesion expansion, there is often a thin layer of hyphae. Observing in the morning light is very obvious. There is a small black point-like ascospora under the epidermis of the leaf sheath of the diseased plant stem or under the epidermis of the dead leaf. Conidia infested the panicles and caused ear rot, similar to the ear rot caused by Fusarium graminearum. The morphological characteristics of the pathogen: The conidia of the bacteria are produced directly on aerial hyphae or on small conidial stems. Conidiophores: spindle, sickle, or sausage, curved, narrow at both ends, obtuse at the end, without pedicel, sometimes base-shaped. 0 to 3 diaphragms. Ascospora ovate or spherical. Ascido-cyst, occasionally round, containing 6-8 ascospores. Ascospores are oval in shape with a diaphragm in the center. The characteristics of the disease: The germs were over the summer on the seeds of the bacteria, in the soil, and on the stubble roots. When the wheat germinated, it began to infest. The pathogens overwintered on unfrozen diseased plants. Above O°C, continue to be harmed. The low temperature and high humidity in the spring and autumn are beneficial to the onset of disease, and it is more prone to disease epidemics. Poorly ventilated and light fields tend to be heavier.
