- Title
Effectiveness of Ethrel as a Male Gametocide in Pearl Millet and its Influence on Ergot.

- Abstract
In field and greenhouse experiments Ethrel (2-chloroethy1 phosphonic acid) was tested for its male gemetocidal effects on pearl miller (Pennisetum americanum) and its subsequent effects on ergot development. Application of Ethrel at 2000 ppm at late boot or early protogyny was the most effective for inducing male sterility in the hybrid, BJ 104. female fertility in a male sterile line, however, was not affected by Ethrel treatment. Ethrel at 2000 ppm applied at the late boot stage resulted in partial paniele exertion, and reduced plant height and panicle length. In vitro Ethrel (2000 ppm) completely inhibited pollen germination but did not affect germination of conidia of Claviceps fusiformis, the causal agent of ergot of pearl millet. Ergot resistance or susceptibility in pearl miller lines was not affected, probably because Ethrel could not induce complete male sterility.
