Filed experiments of 2001 showed that treatments with fungicide either 2 days before or 2 days post inoculation, tebuconazole reduced the disease index of the spikes by 80.32% and 70.64, as well as increased grain yield by 12.95% and 8.74% in comparison to the untreated control. Application of metconazole led to decreases of the disease index by 80.5% and 68.0% and increases of grain yield by 11.41% and 11.45% compared with the untreated plants. In 2002, with the serious occurrence of the head blight, tebuconazole reduced the disease index of the spikes by 76.47% and 78.67% and metconazole reduced the disease index by 82.06% and 81.89% in comparison to the untreated control.

田间药效测定结果表明：与对照相比，接种前2d喷药与接种后2d喷药，2001年，戊唑醇可使小麦赤霉病病情指数分别减少80.32%和70.64%，产量增加12.95%与8.74%；羟菌唑可使小麦赤霉病病情指数减少80.5%和68.0%，产量增加11.41%和11.45%；2002年，在小麦赤霉病严重发生的情况下，戊唑醇能使小麦赤霉病病情指数减少76.47%和78.67%，羟菌唑能使小麦赤霉病病情指数减少82.06%和81.89%，产量增加极显著。
