Abstract:

The effect of Melody Duo 66.75 wp was assayed on pearl millet downy mildew (PMDM). This novel fungicide, a combined preparation of iprovalicarb and propineb, controlled all developmental stages of Sclerospora graminicola. The protective effect of this preparation was due to iprovalicarb and was equipotent to metalaxyl-containing Apron 35 sd and Ridomil 72 MZ wp, whereas the eradicant activity of Melody Duo exceeded that of the two latters at comparative doses. Iprovalicarb was translocated acropetally and exhibited systemically an excellent curative activity. The downy mildewed pearl millet plants recovered after foliar treatments with the preparations. The exploitation of Melody Duo 66.75 wp is recommended against pearl millet downy mildew disease.
