Integrated Pest Management Options

Infection can occur at temperatures of 14°C-25°C (57°F-68°F), especially when the soil moisture levels are high. Seed treatment is the primarily method of control.

Seed Treatment

Do not graze or feed livestock on treated areas for 4 weeks after planting.

Spring barley. Must be diluted with water prior to treatment of seed to ensure uniform coverage. Treated seed will sometimes emerge slower than untreated seed. Avoid late seeding of winter cereals. Do not graze or feed livestock on treated areas for 40 days after planting.

Comments (Days to harvest, label precautions, etc.)
Do not graze or feed livestock on treated areas for 6 weeks after planting.
