Rust Disease

Identifying markers:

• Irregular patches of thinning grass, blades start to develop yellow spots that turn rust colour.
• Spots develop into orange-red pustules that cover the grass blades and can easily transfer onto boots, tools and mowers.
• It affects mainly perennial rye grass and smooth stalked meadow grass. Occasionally fescues and bent grass can be affected.
• prolonged wet warm weather and poor soil nutrient levels provides ideal conditions for rust disease to take hold.
