The germination of
urediniospores produced on leaves treated with fungicides was significantly reduced compared to the control (P=0,05).
DNA was extracted from
urediniospores collected from field infected and inoculated 'Alamo' plants and primers Rust1 (2) and PuccF (5'-CAATGGATCTCTAGGCTCTC-3', B.
For each leaf on which uredinia and
urediniospore production were to be determined, leaf length and width (each in centimeters) were measured the day of inoculation.
Urediniospores mostly oval, cinnamon brown, 14.8-21.7 x 18.8-29.5 um (mean 19.3 x 22.9 um); wall 1-1.6 um; echinulate, germ pores 3 (4), equatorial; pedicel 4.4-5.9 x 7-31.6 um.
UREDINIOSPORES are single celled, globose-ovoid or subglobose, 20-27.5 x 20-30 um, wall 1-1.5 um thick, light brown to reddish brown, smooth, germ pores equatorial and 1-2.
Two types are found on daylilies in the United States and Costa Rica:
urediniospores and teliospores.

Urediniospores of each isolate were collected, dried at room temperature, frozen in liquid nitrogen and immediately stored at -80C for later use.
