The active ingredient iprovalicarb is a new fungicide against diseases cauesed by fungi on grapes, potatoe and vegetables. It belongs to the newly developed group of carbamic acid isopropylesters. The active ingredient propineb is added to iprovalicarb in Melody Duo, the active ingredient folpet in Melody Combi. Iprovalicarb is a highly active systemic ingredient preventing the formation of sporangia and spores. Its very high efficacy is protective, curative and eradicative. After penetrating into the plant tissue it is transported acropetally protecting also the new sprouts. The mechanism of action is different from that performed by other known products therefore the cross-resistance is not to be expected. Both products show a very good toxicological and environmental profile therefore should be used in the integrated production program. The results of the field trials show an exceptional efficacy of Melody Duo against late blight (Phytophthora infestans), downy mildew (Plasmopara viticola) and that of Melody Combi against downy mildew (Plasmopara viticola). Due to the advantages offered by both products they are by all means highly recomended for the antiresistant strategy.
