Potential of NanoPro to reduce fungicide rate for control of Microdochium nivale on an annual bluegrass ( Poa annua) green

摘要

This is a report on the potential of NanoPro~(?)to reduce the rate of two commonly used fungicides for control of Microdochium patch ( Microdochium nivale ), the economically most important turfgrass disease in Scandinavia. The experiment was conducted from 14 Sept. 2018 to 1 May 2019 on an annual bluegrass golf green at the NIBIO Turfgrass Research Center Landvik. Use of NanoPro~(?)at a rate of 292 ml/ha in tank mixture with the systemic fungicide Delaro? SC 325 or/and the contact fungicide Medallion? TL produced the same level of disease control with a 30-60% reduction in fungicide dosage as with full fungicide dosage without additive. NanoPro~(?)was more effective with Medallion? TL than with Delaro? SC 325. We conclude that NanoPro~(?)may have a big potential in Scandinavia and other countries where authorities require reduced fungicide use. The experiment should be repeated one more year before giving final recommendations.
