CYTOLOGICAL EFFECT OF TIL T 250 EC IN THE SUCCESSIVE PHASES OF THE TRITICALE RUST DISEASE PROCESS CAUSED BY PUCCINIA RECONDITA F. SP. TRITICI

摘要

The disease process caused by rust (Puccinia recondita f. Sp. Tritici) in Triticale (Tritcale-Wittmack cv.Bolero) and the effect of the application of the propikonazole-Tilt 250 EC are described. In plants not protected chemically one could observe the whole pathogen developmental cycle ending with the appearance of uredinia with urediniospores. The highest pathogen susceptibility to chemical agent was observed at the time of inoculation, durign incubation and at the beginning of the actual disease.
