The efficacy of seed treatment fungicides against seedling blight and snow mold on winter wheat
Journal Title: Žemės ūkio mokslai - Year 2016, Vol 23, Issue 4
Abstract
The efficiency of seed treatment fungicide on winter wheat was evaluated at the Institute of Agriculture in the Lithu-anian Research Centre for Agriculture and Forestry in 2013–2015. Meteorological conditions at sowing, emergence and early crop development had a major influence on seedling blight infection in winter wheat. The seedling blight severity index of winter wheat treated by seed treatment fungicides at the 2-leaf stage (BBCH 12) was reduced and the test pro-duct efficacy ranged from 27.3 to 85.3% in 2013, from 13.6 to 39.3% in 2014, and from 33.3 to 78.0% in 2015. The seedling blight intensity in early spring was high and in 2014 amount-ed to 58.89%. In 2015 it was 45.00%, and 50.38% in 2016. Chambel 6 FS and Maxim 025 FS gave better efficacy against seedling blight compared to other test seed treatment fungi-cides. Snow mold damaged winter wheat leaves in the early spring of 2015 and 2016, but the incidence of the disease on leaves did not exceed 30%, and the severity was 0.48%. The seed treatment fungicides Bariton® Ultra and Maxim 025 FS were more effective against snow mold
