８０年代末期以来，陕西关中大蒜产区发生了一种原因不明的蒜薹病害，田间病株蒜圣上密生细小白色斑点，继而在贮藏中发生严重腐烂，造成重大经济损失。由病薹成功地分离和鉴定了病原菌。病原菌为膨胀匐柄霉Ｓｔｅｍｐｈｙｌｉ：“ｎｉｖｅｓｉｃａｒｉｚｉｍ（Ｗａｌｌｒｏｔｈ）Ｓｉｍｍｏｎｓ，回接引起相同的症状。该病原菌分生抱子梗直或略弯，淡褐色至褐色，长５６．７１Ｌｍ，宽５～８ｔＬｍ，梗端膨大成囊状，直径７～９Ｐｍ，具暗色带。分生抱子长方形、宽卵形，揽褐色，表面具细刺，具１～６个横隔膜，１～３个纵隔膜，在１～３个主要横隔膜处明显缢缩，尺度１９．２～５３．３Ｘ１３：１～２３．２μｍ，抱子长宽比为１：１．７。在培养中产生有性态Ｐ１ｅｏｓｐｏｒａｓｐ．。该菌还可引起严重的叶枯病。
Since the late 1980s, a garlic sprouting disease of unknown origin occurred in the garlic producing area of Guanzhong in Shaanxi Province. Small white spots were densely populated on the garlic in the field and then suffered severe decay in storage, resulting in significant economic losses. The pathogen was successfully isolated and identified from diseased sedge. The pathogen is the same symptom caused by the swollen Campylobacter Stemphyli: “nivesicarizim (Wallroth) Simmons.” The pathogen spores straight or slightly curved, pale brown to brown, 56.71 Lm long, 5-8 tLm wide, Dilated into a sac-like, diameter 7 ~ 9Pm, with a dark band. Meridian spar rectangular, broad oval, brown, the surface with thin thorns, with 1-6 diaphragm, 1-3 mediastinal in 1 to 3 A major diaphragm at the Department of constriction, scale 19.2 ~ 53.3X13: 1 ~ 23.2μm, spores length to width ratio of 1: 1.7 in culture have a sexual state P1eosporasp .. The bacteria can also cause Serious leaf blight.
