(Azoxystrobin is non-ncogenic in the rat. Based on a study which administered azoxystrobin in the diets of rats the following values were recorded: male rat 3.6 mg/kg/day, female rat 3.6 mg/kg/day at 60 ppm diet; male rat 18.2 mg/kg/day, female rat 22.3 mg/kg/day at 300 ppm diet; male rat 82.4 mg/kg/day, female rat 117.6 mg/kg/dayat 1500/750ppm diet, respectively.)

Application

Biochemistry: Quinone outside inhibitor. Inhibits mitochondrial respiration by blocking electron transfer between cytochrome b and cytochrome c1, at the ubiquinol oxidising site. Controls pathogenic strains resistant to the 14-demethylase inhibitors, phenylamides, dicarboxamides or benzimidazoles.

Mode of action: Fungicide with protectant, curative, eradicant, translaminar and systemic properties. Inhibits spore germination and mycelial growth, and also shows antisporulant activity.

Uses: Controls the following pathogens, at application rates between 100 to 375 g/ha: Erysiphe graminis, Pucciniaspp., Leptosphaeria nodorum, Septoria tritici and Pyrenophora teres on temperate cereals; Pyricularia oryzae andRhizoctonia solani on rice; Plasmopara viticola and Uncinula necator on vines; Sphaerotheca fuliginea andPseudoperonospora 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; Elsino? fawcettii, Colletotrichum spp. and Guignardia citricarpa on citrus; Colletotrichumspp. and Hemileia vastatrix on coffee.

Phytotoxicity Good crop safety, except on some varieties of apple (e.g. McIntosh, Cox).
