Fungicides for Use in Forage Seed Grasses
Project Objectives: The Saskatchewan Forage Seed Development Commission (SFSDC) wanted to demonstrate the use of registered fungicides, Tilt 250 E (propiconozole) on timothy and Headline EC (pyraclostrobin) on perennial ryegrass, to determine if leaf disease could be controlled and seed yield and quality improved.
Project Rationale: Recently, some forage seed producers in Saskatchewan have reported an increase in leaf diseases that have negatively affected their grass seed fields. The main plant disease of concern on perennial ryegrass is rust (Puccinia graminis Pers.) and the main disease of concern on timothy is purple eyespot (Cladosporium phlei). The local producers wanted to see timing and efficacy of Headline and Tilt fungicide applications and also if there were economic returns for the application.
