From 1969 to 1978, 51 different chemical formulations were tested as seed treatments for the control of seed-borne and soil-borne common bunt of wheat. Formulations that controlled both seed-borne and soil-borne bunt at practical rates were those that contained carboxin, CGA-64251, fenapanil, hexachlorobenzene, methfuroxam, nuarimol, pentachloronitrobenzene (PCNB), thiabendazoles, triadimefon or triadimenol. Formulations containing benomyl, chloroneb, fuberidazole, maneb, pyracarbolid, TCMTB or Zn ion-maneb complex were effective against seed-borne but not soil-borne bunt. CGA-64251, methfuroxam and triadimenol apparently are more potent against bunt than hexachlorobenzene.
