| 摘 要： | 小麦白粉病菌以分生孢子在山区背阴潮凉处的自生麦苗上越夏,以潜育菌丝在小麦寄主组织内为主要越冬方式。春季病害流行与菌源量,发病关键月的温湿度、日照时数等密切相关。326份小麦品种(系)抗性鉴定,鲁麦13、14、16,莱农8442等品种抗性和丰产性较好,并选出一批抗性好的新品系和抗源材料。试验表明,亩用45％硫磺胶悬剂167毫升与20％粉锈灵乳油15毫升混用,是目前防治小麦白粉病较好的混配药剂

| Abstract: | The fungi of wheat powdery mildew oversummer by means of conidia on spontaneous wheat plants in shady and moist mountain area and overwinter by hosting with hyphae in wheat tissue mainly. The disease epidemic in spring was correlated closely with the amount of infective sources, sunshine duration, and temperature and humidity in crucial diseasing months. Varieties, such as Lumai 13, 14, 16, Lainong 8442 etc, were identified to be good at resitance and productivity from 326 samples of wheat germplasm resources tested. Trials showed that 45% suspended sulphur 167ml mixed with 20% tridimefon 15ml per mu was better for controlling wheat powdery mildew. |
