Učinkovina iprovalikarb je nov fungicid za zatiranje gliv plesnivk na vinski trti, krompirju in vrtninah. Spada v novo odkrito skupino aminokislinskih amid-karbamatov. V sredstvu Melody Duo je iprovalikarbu dodana dotikalna učinkovina propineb, v Melody Combiju pa folpet.

Iprovalikarb je sistemična učinkovina, ki preprečuje rast kličnega mešička zoospor, sporangijev, rast micelija in sporulacijo gliv plesnivk. Deluje preventivno, kurativno in eradikativno. Po rastlini se premešča akropetalno in varuje tudi na novo zrasle poganjke. Način delovanja se razlikuje od dosedaj znanih sredstev, zato ni nevarnosti navzkrižne rezistence. Sredstvi imata zelo ugoden toksikološki in ekotoksikološki profil, kar jima omogoča uvrstitev v programe integrirane pridelave. Melody Duo je v poskusih pokazal odlično delovanje proti krompirjevi plesni (Phytophthora infestans) in peronospori vinske trte (Plasmopara viticola), Melody Combi pa proti peronospori vinske trte (Plasmopara viticola). Zaradi svojega načina delovanja sta vsekakor dobrodošli sredstvi v antirezistenčni strategiji.

ABSTRACT

New systemic fungicides against diseases caused by fungi:
Melody Duo and Melody Combi, composed for a healthy crop

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.
