Control of Sclerotinia sclerotiorum infection in oilseed rape with strobilurin fungicide SYP-7017
Canadian Journal of Plant Pathology 36 (3), 354-359
Abstract: SYP-7017, a broad-spectrum fungicide, belongs to the chemical group of strobilurins. Baseline sensitivity of Sclerotinia sclerotiorum (Lib) de Bary to SYP-7017 was determined using 120 strains collected during 2010 and 2011 from rapeseed fields without a previous history of strobilurin usage in Jiangsu Province, China. The median effective concentration (EC₅₀) values for SYP-7017 that inhibited mycelial growth ranged from 0.006 to 0.047 µg mL⁻¹ (mean of 0.016 µg mL⁻¹). No cross-resistance between SYP-7017 and carbendazim or iprodione was detected. On detached rapeseed leaves, SYP-7017 at 100 µg mL⁻¹ provided over 90% control efficacy. Moreover, SYP-7017 exhibited good characteristics of absorption and translocation, and also exhibited excellent protective activity in pot experiments. In field trials, control efficacies of SYP-7017 at 75 g a.i. ha⁻¹ and 187.5 g a.i. ha⁻¹ were 80.2% and 91.58%, respectively, higher than other traditional fungicides. These results suggest that SYP-7017 has strong antifungal activity and a potential application in controlling S. sclerotiorum.
