稻曲病是水稻上的一种毁灭性病害。由于初侵染源是土壤中的厚垣孢子，2016年和2017年试验了在水稻土中拌入生石灰结合在水稻抽穗前对沉水土壤喷洒杀菌剂司益康唑对稻曲病发病率的影响。施用生石灰可降低稻曲病的成球数，在稻田中追加喷施烯效唑可进一步降低稻曲病的发病率。结果表明，生石灰可降低田间土壤中厚垣孢子的数量，生石灰与硅益康唑配合施用对防治该病有较好的效果。
Rice false smut caused by Villosiclava virens is a devastating disease of rice. Because the primary infection source is chlamydospores in the soil, the effect of mixing calcined lime into paddy soil in combination with spraying the fungicide simeconazole on submerged soil before rice heading on the incidence of rice false smut was tested in 2016 and 2017. The calcined lime decreased the number of false smut balls, and additional spraying of simeconazole on paddy fields further decreased the incidence. Our findings suggest that calcined lime may be decreased the number of chlamydospores in field soil, and calcined lime applied with simeconazole is effective for controlling the disease.
