DETECTION OF THE CAUSAL AGENT OF TAN SPOT (PYRENOPHORA TRITICI-REPENTIS) USING SPORE-CATCHING DEVICES

Drechslera tritici-repentis (Died.) Shoem. (teleomorph Pyrenophora tritici-repentis (Died.) Drechsler) is the causal agent of a tan spot, a major wheat disease worldwide. Wheat yield losses can reach up to 60%. Accurate and timely monitoring of harmful objects is crucial for effective crop protection against economically significant pathogens. Thus, in our study, we aim to evaluate the detection of tan spot operating spore trapping devices of various designs. As a result, the possibility of detecting tan spot pathogen spores using various spore-catching devices was shown. The number of pathogen spores caught by different devices varied from 1 pc. up to 18 pcs. depending on the design of the device, variety and sampling time. Our study demonstrates that spore traps of various designs help to detect tan spot prior to its visible manifestation at its minimum development (up to 1-5%). It's, crucial for the development of effective protective measures.
