年在爱荷华州的个地点,在大豆Glycine max()、和期进行了杀真菌剂唑菌胺酯(嗜球果伞素)和戊唑醇(苯三唑)施用试验研究,评价了大豆田间茎和种子被Phomopsis spp.侵染的发病率、产量和种子品质。结果表明,2008—2009年在R3+R5时期和2008年在R5时期施用唑菌胺酯后,大豆茎Phomopsis spp.发病率降低,较对照未施药剂茎Phomopsis spp.发病率大约降低三分之二。2009年,在R3时期施用戊唑醇和在R5时期施用唑菌胺酯,可显著降低种子Phomopsis spp.发病率,与对照未施药剂相比大约降低三分之一。2009年只有在R3+R5时期施用唑菌胺酯可同时降低茎和种子Phomopsis spp.发病率。在温暖
A pilot study on the application of the fungicides pyraclostrobin (strobilurin) and tebuconazole (benzotriazole) was conducted in soybeans Glycine max at various locations in Iowa, Soybean Stems and Seeds Infected by Phomopsis spp. Incidence, Yield and Seeds Quality. The results showed that the incidence of Phomopsis spp. In soybean stem decreased after application of pyraclostrobin in the period of R3 + R5 and 2008 in R5 of 2008-2009, and the incidence of soybean Phomopsis spp was reduced by about one third two. In 2009, application of tebuconazole at period R3 and pyraclostrobin at stage R5 significantly reduced the incidence of seed Phomopsis spp. By approximately one-third as compared to the control untreated dose. In 2009, the application of pyraclostrobin during the period of R3 + R5 both reduced the incidence of stem and seed Phomopsis spp. In warmth
