Abstract：
Fluopimomide is a novel acid amide fungicide registered for the control of many plant pathogens. In the present study, the effects of soil-treated fluopimomide on soil micro biomass, disease incidence, plant growth, soil enzyme activity, and marketable yield of tomato (Solanum lycopersicum L.) were investigated via field trial. In addition, the application prospect in China was also evaluated. In the experiment, five treatments with three replications and a randomized complete block design were followed. The treatments were: furrow application of fluopimomide (25% suspension concentrate, SC) at the dosage of 375, 750, and 1,500 g ha-1, which was recommended, double recommended, and quadruple recommended dosages, respectively. Besides, common control fungicide fluopicolide (5% SC) furrow was applied at recommended application dosages of 750 mL ha-1, and a non-treated control was also undertaken. Results indicated that fluopimomide exhibited no effects on the amount of soil bacteria and actinomycetes, and its inhibition effect on fungi amount could be recovered at 60 days after treatment (DAT). With the recommended application dosage, fluopimomide could efficiently reduce the number of plant pathogens in soil by 79.56-85.80%, significantly reduce the disease incidences in tomato plants by 80.00-88.24%, and improve plant height by 13.25-24.05% and marketable yield by 16.88%. Furthermore, soil enzymes exhibited a complex response to fluopimomide, and AOB and nifH gene copy numbers were increased by the double and quadruple recommended dosage of fluopimomide. Based on the above results, fluopimomide could be recommended as an efficient fungicide for the tomato field.
摘要：
氟哌胺是一种新型的酸性酰胺杀真菌剂，可用于控制许多植物病原体。在本研究中,土壤处理氟哌胺对土壤微生物量的影响,疾病发病率,植物生长,土壤酶活性，通过田间试验研究了番茄（SolanumlycopersicumL.）的可销售产量。此外,并对其在中国的应用前景进行了评价。在实验中,我们遵循5种重复3次的治疗方法和随机完全区组设计.处理方法是:沟槽应用氟奥匹胺(25%悬浮浓缩物，SC)在375、750和1,500克ha-1的剂量下，这是推荐的，双人推荐,和四倍的推荐剂量，分别。此外,以750mLha-1的推荐施用剂量施用普通对照杀菌剂氟吡唑（5％SC）沟，并进行了未处理的对照。结果表明，氟哌胺对土壤细菌和放线菌的数量没有影响，处理后60天（DAT）可恢复对真菌的抑制作用。在推荐的应用剂量下，氟哌米胺可有效减少土壤中植物病原菌的数量79.56-85.80%，显著降低番茄植株的发病率80.00-88.24%，株高提高13.25-24.05%，适销产量提高16.88%。此外，土壤酶对氟哌米特表现出复杂的反应，和AOB和nifH基因拷贝数增加了两倍和四倍的氟哌米特推荐剂量。基于以上结果,氟哌胺可被推荐为番茄田的有效杀菌剂。
