摘要：

小麦茎基腐病是由镰刀菌侵染引起的一种重要的真菌性土传病害，在小麦产区呈流行态势，严重威胁中国小麦的安全生产。本研究评价了不同的种衣剂处理、以及返青期喷药对小麦茎基腐病的综合防控效果。从拌种剂对苗期的影响来看：多粘类芽孢杆菌（≥5亿cfu/g）FC+三氟吡啶胺(200 g/L)FS组合能显著增加麦苗的4项评价指标，且能显著降低苗期的病株率。拔节期调查发现：各处理都能较好的控制小麦茎基腐病的扩散流行，以多粘类芽孢杆菌（≥5亿cfu/g）600mL FC+三氟吡啶胺(200 g/L)300mL FS组合效果最好，病株率为15.55%。灌浆期调查结果表明：多粘类芽孢杆菌（≥5亿cfu/g）FC+三氟吡啶胺(200 g/L)FS组合能较好控制小麦茎基腐病，病茎率为17.78%~23.33%，防效为77.27%~83.74%。最终的测产结果表明：多粘类芽孢杆菌（≥5亿cfu/g）FC+三氟吡啶胺(200 g/L)FS组合最优，小麦增产率为16.03%~17.55%，生产上可以采用此药剂组合进行种子包衣预防小麦茎基腐病。

Abstract:

Wheat crown rot is an important soil-borne fungus disease which caused by Fusarium pseudograminearum primarily. It is prevalent in wheat producing areas, which threatens the safety of wheat production in China seriously. This study evaluated the comprehensive control efficacy of different seed coating agentsand sprayings at the returning green stage on crown rot of wheat. From the control efficacy of seed coating agents at seedling stage, the mixture of Seed coating agent Paeniocollus polymyua (≥500 million cfu/g) FC and Tymirium (200 g/L) FS significantly increased four evaluation indexes and reduced the incidence rate of wheat seedling diseases significantly. Every treatment could control the spreading speed at jointing stage, but the combination of Paeniocollus polymyua (≥500 million cfu/g) FC 600 mL and Tymirium (200 g/L) FS 300 mL was the best treatment, and the diseased rate was 15.55%. The combination of Paeniocollus polymyua (≥500 million cfu/g) FC and Tymirium (200 g/L) FS was the best treatment to control wheat crown rot at filling stageas well, the diseased stem rate was 17.78%-23.33%, the control efficacy was 77.27%-83.74%. The final results showed that the combination of Paeniocollus polymyua (≥500 millioncfu/g) SC and Tymirium (200 g/L) FS was the best treatment, the yield increase rate was 16.03%-17.55%. In practice, this combination could be used for seed coating to control the wheat crown rot.
