| Abstract/Contents: | "The endophytic fungus Epichloe typhina, associated with fescue toxicosis in cattle, is easily detected in leaf sheaths, stems and seeds of tall fescue using ELISA. The fungus is widely distributed in Ky; 194 of 200 fields (97%) surveyed in 1981 were enfested. Compounds having antifungal activity in an agar plate assay (ED50 <5ppm) were propiconazol, etaconazole, fenarimol, nuarimol, imazalil, prochloraz benomyl, thiabendazole, triadimenol and bitertanol. Certain of these fungicides were used for seed, pot and field treatments. Infected seed treated with Baytan (triadimenol) at 5.2, 3.9, 2.6 and 1.3 gm ai/kg seed gave 100, 85, 45 and 25% control of the endophyte in 12 week old seedlings, respectively. Other fungicides gave 15-80% control depending on concentration. The fungus was eradicated from infected plants in pots in the greenhouse by Baycor (bitertanol, 2.5 mg ai/g soil). The endophyte could not be controlled in the field by foilar application of various fungicides." |
