Macrophomina phaseolina균(菌)을 이용(利用)하여 살균제 Triadimefon의 밀 품종 Kharchia와 Lal Bahadur에 있어서 수확후의 잔류량을 조사한 결과 살포식물의 밀짚에서는 Triadimefon이 검출되었으나 밀 종자에서는 검출되지 않았다. 잔류량 조사를 위해 개발된 박층(薄層) 크로마토그라피에 의하여도 동일한 결과를 얻었다. 기주체내에서 Triadimefon은 Triadimenol로 전환되었다.

By using the test fungus Macrophomina phaseolina, residues of triadimefon were found in straw collected after harvest from sprayed plants of wheat varieties Kharchia and Lal Bahadur but grains contain no such residues. Thin layer chromatographic method was developed to detect residues of the fungicide which was found to be present in straw of sprayed plants of both the varieties. No residues could be detected in grain samples. It was found that triadimefon was converted in triadimenol in/to host.
