Azoxystrobin 25% + Difenoconazole 15% Sc

Azoxystrobin 25% +Difenoconazole 15% SCAzoxystrobin NOMENCLATURE
Common name azoxystrobine ((f) F-ISO); azoxystrobin (BSI, E-ISO)
IUPAC name methyl (E)-2-{2-[6-(2-cyanophenoxy)pyrimidin-4-yloxy]phenyl}-3-methoxyacrylate
Chemical Abstracts name methyl (E)-2-[[6-(2-cyanophenoxy)-4-pyrimidinyl]oxy]-α-(methoxymethylene)benzeneacetate
CAS RN [131860-33-8], formerly [215934-32-0]Azoxystrobin Biochemistry Quinone outside inhibitor. Inhibits mitochondrial respiration by blocking electron transfer between cytochrome band cytochrome c1, at the ubiquinol oxidising site. Controls pathogenic strains resistant to the 14-demethylase inhibitors, phenylamides, dicarboxamides or benzimidazoles.Azoxystrobin Mode of action Fungicide with protectant, curative, eradicant, translaminar and systemic properties. Inhibits spore germination and mycelial growth, and also shows antisporulant activity.Azoxystrobin Uses Controls the following pathogens, at application rates between 100 to 375 g/ha: Erysiphe graminis, Puccinia spp., Leptosphaeria nodorum, Septoria tritici and Pyrenophora teres on temperate cereals;and Rhizoctonia solani on rice; Plasmopara viticola and Uncinula necator on vines; Sphaerotheca fuliginea and Pseudoperonospora cubensis on cucurbitaceae; Phytophthora infestans and Alternaria solani on potato and tomato; Mycosphaerella arachidis, Rhizoctonia solani and Sclerotium rolfsii on peanut; Monilinia spp. and Cladosporium carpophilum on peach; Pythium spp. and Rhizoctonia solani on turf; Mycosphaerella spp. on banana; Cladosporium caryigenum on pecan; Elsinoë fawcettii, Colletotrichum spp. and Guignardia citricarpa on citrus; Colletotrichum spp. and Hemileia vastatrix on coffee.Azoxystrobin Phytotoxicity Good crop safety, except on some varieties of apple (e.g. McIntosh, Cox).DifenoconazoleAPPLICATIONS
Difenoconazole Biochemistry Sterol demethylation inhibitor. Inhibits cell membrane ergosterol biosynthesis, stopping development of the fungus.Difenoconazole Mode of action Systemic fungicide with preventive and curative action. Absorbed by the leaves, with acropetal and strong translaminar translocation.Difenoconazole Uses Systemic fungicide with anovel broad-range activity protecting the yield and crop quality by foliar application or seed treatment. Provides long-lasting preventive and curative activity against Ascomycetes, Basidiomycetes and Deuteromycetes, including Alternaria, Ascochyta, Cercospora, Cercosporidium, Colletotrichum, Guignardia, Mycosphaerella, Phoma, Ramularia, Rhizoctonia, Septoria, Erysiphe and Venturia spp., Erysiphaceae, Uredinales and several seed-borne pathogens. Used against disease complexes in grapes, pome fruit, stone fruit, potatoes, sugar beet, oilseed rape, bananas, cereals, rice, soya beans, ornamentals and various vegetable crops, at 30-125 g/ha. Used as aseed treatment against arange of pathogens in wheat and barley, at 3-24 g/100 kg seed. Phytotoxicity In wheat, early foliar applications at growth stages 29-42 might cause, in certain circumstances, chlorotic spotting of leaves, but this has no effect on yield.
