菌核病（Selerotinia stem rot，SSR）是由核盘菌（Sclerotinia sclerotiorum（Lib.）de Bary，是一种重要的大豆[Glycine max（L.）梅尔。]疾病发生在中北部。在威斯康星州的简斯维尔、沙龙和沃纳基进行的一项为期3年的农场研究中，评估了耕作、作物顺序和品种对SSR发生率和大豆产量的影响。在这项研究中，采用裂-裂区设计，主区是耕作：犁板（MB）、凿犁（CP）或免耕（NT）;子区是1995年的作物：玉米（Zea mays L.），小粒谷物或大豆;子小区是1996年的作物：玉米、小粒谷物或大豆栽培品种。子-子-子样地为1997年种植的大豆品种。1997年，简斯维尔和沃纳基的SSR发病率平均>40%，
Selerotinia stem rot (SSR), caused by Sclerotinia sclerotiorum (Lib.) de Bary, is an important soybean [Glycine max (L.) Merr.] disease in the North Central States. The effect of tillage, crop sequence, and cultivar on SSR incidence and soybean yield was evaluated in a 3-yr on-farm study conducted at Janesville, Sharon, and Waunakee, WI. In the study, arranged in a split-split-split-split plot design, main plots were tillage: moldboard (MB), chisel plow (CP), or no-till (NT); subplots were 1995 crops: corn (Zea mays L.), small grain, or soybean; sub-subplots were 1996 crops: corn, small grain, or soybean cultivar. Sub-sub-subplots were soybean cultivars planted in 1997. In 1997, SSR incidence averaged >40% at Janesville and Waunakee, and
