Effect of propiconazole (Tilt 250 EC) and Drechslera poae on germination capacity of Kentucky blue grass

The effect of leaf spot and melting out disease and chemical control on seed quality of Kentucky bluegrass was investigated over two seasons in three treatments: natural infection, inoculation by Drechslera poae and Tilt 250 EC (propiconazole) application. Disease incidence in the treatment with natural infection was low and in the treatment with inoculation was much heavier. Application of propiconazole and occurrence of leaf spot and melting out disease not affected germination capacity of Kentucky bluegrass. Future experiments are needed to confirm obtained results.
