Shantou is an important economic crop in the town of Sijia in Haimen City. The annual planting area reaches 1,000 mu. In recent days, there have been epidemics in the taro in some plots. There are yellowing and dead leaves and other symptoms. The disease mainly damages taro leaves and bulbs. At the beginning of the disease, yellowish-brown lesions appear on the leaves, and then the lesions expand and merge into a round or irregular shape. The upper concentric ring-streak pattern occurs. When the humidity is high, the surface of the lesion produces white moldy material. The diseased necrotic tissue secreted yellow to light brown droplets, and the later lesions were mostly corrupted from the center into cracks. The severely damaged leaves only had leaf veins and showed a broken umbrella. Underground bulb damage can cause browning and rot in some tissues. The pathogens of tachyzoite are repeatedly infested by wind and rain, causing frequent rainfall and heavy rainfall. Areas with low topography, partial nitrogen fertilizers, excessive dense planting, and over-expansion are heavy. The disease resistance of different steamed bread varieties was different. Waterlogging was more resistant to drought and flood, and camphor was more resistant than red buds and white buds. The field where the disease occurs can be sprayed with 25% metalaxyl WP 600 to 700 times, once every 7 to 10 days, and continuously controlled 3 to 4 times. To prevent taro disease, disease-resistant varieties should be selected, and disease-free species should be selected; rational fertilization should be applied without applying partial nitrogenous fertilizer; phosphorus and potassium fertilizers should be added and farmyard fertilizers added; deep-groove sorghum should be cultivated, and timely drainage should be conducted in case of rain; Remove diseased leaves in time. In the case of severe disease, it is recommended to implement a rotation for 1 to 2 years to eradicate the sporadic disease in the field and collect the diseased body to be buried or burned.
