摘要: 【目的】 研究筛选开展防治小麦雪腐(霉)病的田间药剂,为新疆地区小麦雪腐(霉)病防治提供指导。【方法】 采用随机区组的方法,调查各处理小麦雪腐(霉)病发生情况及1 m双行内小麦总茎数、发病茎数,测量小麦地上部鲜重和地下部鲜重。【结果】 9%氟环·咯·苯甲悬浮种衣剂200和400 mL/100 kg种子处理小麦返青总茎数分别为(220.33±9.82)和(202.67±7.84)株/0.3 m2,显著高于CK处理的返青总茎数,高于2.5%咯菌腈悬浮种衣剂、3%苯醚甲环唑悬浮种衣剂处理的返青总茎数。9%氟环·咯·苯甲悬浮种衣剂200和400 mL/100kg种子处理小麦整株鲜重为(6.79±0.33)和(7.35±0.05) g/株,显著高于或高于2.5%咯菌腈悬浮种衣剂、3%苯醚甲环唑悬浮种衣剂和CK处理的小麦整株鲜重。9%氟环·咯·苯甲悬浮种衣剂200和400 mL/100kg种子处理对小麦雪腐(霉)病的防效分别为78.03%和79.63%,显著高于2.5%咯菌腈悬浮种衣剂处理的防效,高于3%苯醚甲环唑悬浮种衣剂处理的防效;各药剂处理对小麦生长发育无异常影响,无药害。【结论】 9%氟环·咯·苯甲悬浮种衣剂处理显著增加了小麦返青总茎数,显著提高了小麦根系生长,起到健苗壮苗的作用。9%氟环·咯·苯甲悬浮种衣剂按照200~400 mL/100kg种子拌种,可有效防治新疆地区冬小麦雪腐(霉)病的发生危害。

Abstract: 【Objective】 To study the field medicament screening test of wheat snow rot (mildew) disease and provide guidance for the scientific control of the disease in Xinjiang. 【Method】 Randomized block design was used to investigate the occurrence of wheat snow rot (mildew), the number of total stems and diseased stems in 1 m double row in each treatment. At the same time, the fresh weight of wheat above ground and underground was measured. 【Result】 The total stem numbers of wheat treated with 9% sedaxane – fludioxonil – difenoconazole SC with the dosage of 200 mL / 100kg seed and 400 mL / 100kg seed were (220.33 ± 9.82) and (202.67 ± 7.84) plants / 0.3 m2, respectively, which was significantly higher than that of CK treatment, and higher than that of 2.5% fludioxonil SC and 3% difenoconazole SC. The fresh weight of the whole plant of wheat treated with 9% sedaxane – fludioxonil – difenoconazole SC with the dosage of 200 mL / 100kg seed and 400 mL / 100kg seed was (6.79 ± 0.33) and (7.35 ± 0.05)g / plant, respectively, higher than those of wheat plant treated with 2.5% fludioxonil SC, 3% difenoconazole SC and CK. The control effects of the treatment of 200 mL / 100kg seeds and 400 mL / 100kg seeds with 9% sedaxane – fludioxonil – difenoconazole SC on wheat snow rot (mildew) were 78.03% and 79.63%, respectively, which was significantly higher than that of 2.5% fludioxonil SC, and higher than that of 3% difenoconazole SC. All the treatments did not negatively influence the growth and development of the wheat. 【Conclusion】 The treatment of 9% sedaxane – fludioxonil – difenoconazole SC significantly increase the total stem number of wheat, the root growth of wheat, which will play a role in making seedlings stronger. 9% sedaxane – fludioxonil – difenoconazole SC with the dosage of 200 mL / 100kg seed can effectively prevent and control the occurrence and damage of winter wheat snow rot (mildew) in Xinjiang.

Key words: winter wheat; seed coating agents; wheat snow rot (mildew); control effect
