摘要:

为了提升对小麦赤霉病及其毒素脱氧雪腐镰刀菌烯醇(DON)的防治效果,本研究于2024年和2025年采用24%井冈霉素A SL与37%苯醚菌酯·戊唑醇SC进行协同施药,探究了不同施药频次与协同剂量对赤霉病发病指数及籽粒DON含量的影响。结果表明,2次施药对赤霉病及DON毒素的防治效果均显著高于1次,但与3次施药差异不显著。单独使用37%苯醚菌酯·戊唑醇SC(375 mL/hm2 1~3次施药)时,对赤霉病的病指防效为62.94%~89.89%,对DON毒素的防效为46.09%~72.26%。24%井冈霉素A SL对DON毒素防效显著高于其对赤霉病的病指防效,显示出减少籽粒DON积累的潜力。24%井冈霉素A SL协同施药后,病指防效和DON防效均进一步提高,且随井冈霉素A剂量增加,增效作用更显著。本研究证明,合理采用24%井冈霉素A SL与37%苯醚菌酯·戊唑醇SC协同施药2次,可有效控制小麦赤霉病和DON毒素污染,为提升小麦品质安全提供了技术支撑。

Abstract:

To enhance the control efficacy against fusarium head blight (FHB) and deoxynivalenol (DON) mycotoxins in wheat, field experiments were conducted in 2024 and 2025 by combined application of 24% Jinggangmycin A soluble concentrate (SL) and 37% bemystrobin·tebuconazole suspension concentrate (SC), and the control efficacy of different application frequencies and combined dosages on FHB and grain DON content were investigated. The results showed that two times of applications provided significantly higher control efficacy against both FHB and DON mycotoxins than one time, but no significant difference was observed between two and three times of applications. When applied alone at 375 mL/hm2 for 1-3 times, 37% bemystrobin·tebuconazole SC achieved a disease index control efficacy of 62.94%-89.89% against FHB and a DON mycotoxins control efficacy of 46.09%-72.26%. The control efficacy of 24% Jinggangmycin A SL against DON mycotoxins was significantly higher than its control efficacy against the disease index of FHB, demonstrating its potential to reduce DON accumulation in grains. After combined application of 24% Jinggangmycin A SL, both the disease index control efficacy and DON control efficacy were further improved, and the synergistic effect became more pronounced with the increase of Jinggangmycin A dosage. Reasonable combined application of 24% Jinggangmycin A SL and 37% bemystrobin·tebuconazole SC twice can effectively control FHB and DON contamination, providing technical support for improving wheat quality and safety.
