In the control of Sphaerotheca pannosa var. rosae on rose Tolylfluanide + tebuconazole (Folicur Multi 50 WG at concentration 0.1%) was used for spray 2 -times at 14-day-intervals or 4-times at 7-day-intervals. After 4 weeks of plants protection effectiveness of tested product was about 75%. In the control of Diplocarpon rosae, the product was applied when first disease symptoms appeared on rose shrubs. Application was repeated 5-times at 14-day-intervals or 9-times at 7-day-intervals. After 9 week-protection effectiveness of tested product was about 85% and depended on frequency of sprayings. In the control of Puccinia horiana on chrysanthemum, Tolylfluanide + tebuconazole was used as plant spray twice at 14-day-intervals or 4-times at 7-day-intervals. After 4 week-protection the product suppressed of new telia formation about 55%. Application of the product for willow rust (Melampsora epitea) control suppressed formation of new uredia about 86% and half of them were dried. In the control of pelargonium rust (Puccinia pelargonii-zonalis) the product was used as plant spray 4-times at 7-day-intervals. It suppressed formation of new uredia about 90% and 1/3 of them were dried. It was found that 1 or 7 days after rose spray, spores of D. rosae collected from leaf blades only in 6% germinated. Spores taken from nonspraying leaves germinated in 90%. In case of P. pelargonii-zonalis, after 1 or 7 days after spraying, spores collected from protected plants germinated at 3%, compared to 90% on untreated plants. Spores of B. cinerea, collected from protected plants germinated at about 10%, whereas on control leaves at 90%.
在防治玫瑰上的蔷薇单囊壳菌变种（Sphaerotheca pannosa var. rosae）时，使用了甲苯氟磺胺+戊唑醇（浓度为0.1%的富力库多效50%可湿性粉剂），每隔14天喷雾2次或每隔7天喷雾4次。在对植株进行4周的保护后，受试产品的防治效果约为75%。在防治玫瑰炭疽病菌（Diplocarpon rosae）时，当玫瑰灌木上首次出现病害症状时施用该产品。每隔14天重复施用5次或每隔7天重复施用9次。在进行9周的保护后，受试产品的防治效果约为85%，且取决于喷雾频率。在防治菊花上的白锈菌（Puccinia horiana）时，甲苯氟磺胺+戊唑醇用作植物喷雾剂，每隔14天喷雾2次或每隔7天喷雾4次。在进行4周的保护后，该产品抑制新夏孢子堆形成约55%。施用该产品防治柳树锈病（Melampsora epitea）抑制新夏孢子堆形成约86%，其中一半干枯。在防治天竺葵锈病（Puccinia pelargonii-zonalis）时，该产品用作植物喷雾剂，每隔7天喷雾4次。它抑制新夏孢子堆形成约90%，其中三分之一干枯。发现对玫瑰喷雾1天或7天后，从叶片上收集的玫瑰炭疽病菌孢子只有6%发芽。从未喷雾叶片上采集的孢子发芽率为90%。对于天竺葵锈病，喷雾1天或7天后，从受保护植株上收集的孢子发芽率为3%，而未处理植株上的孢子发芽率为90%。从受保护植株上收集的灰葡萄孢菌（Botrytis cinerea）孢子发芽率约为10%，而对照叶片上的孢子发芽率为90%。
