Other beneficial spp. Harmless to non-target organisms, including predatory mites and bugs, spiders, lacewings, hoverfly, ladybird,

carabid beetle, parasitoid wasps and bees, under field conditions at field application rates (IOBC); e.g. LR50 (7 d) for Typhlodromus pyri >1500 g/ha; LR50 (48 h) for

Aphidius rhopalosiphi >1135 g/ha.


Environmental Fate
Animals In rats, the majority of radiolabel is excreted in the faeces, with little remaining radioactivity in any tissues of the animal. A large number of metabolites was formed, of which only the glucuronide of azoxystrobin acid is present at >10% of the administered dose. In goats and hens, azoxystrobin is also excreted rapidly,with low residues in milk, meat or eggs. For details, see R. S. I. Joseph in "Pesticide Chemistry and Bioscience". Plants In wheat, grapes and peanuts, metabolism was extensive, but parent azoxystrobin was the only major (>10%) residue. Metabolism followed similar pathways in all three crops. Soil/Environment Average DT50 (lab.) 8 w (20 °C, pF 2). In soil, in the dark, six identified metabolites were formed; over 1 y, 45% of applied radiolabel is evolved as CO2. Dissipation in the field is faster, average DT50 2 w, DT90 41 w. On soil, photolysis DT50 11 d. Azoxystrobin and its degradates have low to moderate mobility in soil; typical Koc for azoxystrobin c. 500. Field dissipation studies showed that neither azoxystrobin nor its major degradates were typically found in soil below the top 15 cm.

 

Usage: Controls the following pathogens: Erysiphe graminis, Puccinia spp., Leptosphaeria nodorum, Septoria tritici and Pyrenophora teres on temperate cereals;

Pyricularia oryzae 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; Colletotrichum spp. and Guignardia citricarpa on citrus; Colletotrichum spp. and Hemileia vastatrix on coffee. Phytotoxicity Good crop safety, except on some varieties of apple (e.g. McIntosh, Cox).

 

Application: Biochemistry 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, Puccinia spp., Leptosphaeria nodorum, Septoria tritici and Pyrenophora teres on temperate cereals; Pyricularia oryzae 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;
