Application
143390-89-0 is a quinone outside Inhibitor, inhibiting mitochondrial respiration by blocking electron transfer between cytochrome b and cytochrome c1, at the ubiquinol oxidising site. Selectivity is partly due to enzymic de-esterification within plants. Mode of action Fungicide with protective, curative, eradicative and long residual disease control; acts by inhibiting spore germination. Redistribution via the vapour phase contributes to activity. Used to control scab in apples and pears (Venturia spp.); powdery mildew on apples (Podosphaera leucotricha), vines (Uncinula necator), cucurbits (Sphaerotheca fuliginea) and sugar beet (Erysiphe betae); mildew (Erysiphe graminis), scald (Rhynchosporium secalis), net blotch (Pyrenophora teres) and glume blotch (Septoria nodorum) on cereals; and mildew (Leveillula taurica, Erysiphe spp., Alternaria spp.) on vegetables.
