Azoxystrobin
Check formulations and concentrations, then enquire about specifications, documents and supply for your market.
Formulations & concentrations
Technical materials, single-active formulations and mixtures are listed separately. Specifications added to the enquiry list can be sent together with other products in one purchase or registration enquiry.
Technical materials
For formulation development or manufacture: define the technical material, assay, impurity profile and source documentation, then agree the processing and quality requirements.
Single-active formulations
Select the concentration and formulation for the intended product. Confirm the complete specification, packaging and destination-market label before arranging a sample or order.
Mixture formulations
Confirm each active ingredient and its concentration, together with the finished formulation. Review quality documents and the proposed registered uses for the complete mixture.
The supplied product, specification, packaging and applicable uses are confirmed for the destination market and the agreed supply arrangement.

Mode of action & use
Mode of action
Binds the Qo site of cytochrome b (mitochondrial complex III) and blocks respiration, stopping spore germination and early infection.
Systemic and translaminar: moves within the plant and through the leaf.
Typical targets and crops
Broad spectrum across ascomycetes, basidiomycetes and oomycetes, including rusts, powdery and downy mildews, leaf spots and rice blast. Used in cereals, rice, soybean, fruit, vegetables and turf.
Resistance management · FRAC 11
Quinone outside inhibitors (QoI) carry a high resistance risk; a single target-site mutation can cause loss of control. Use them preventively, in mixture or strict alternation with other groups, and limit the number of QoI applications per season.
This is general information on the active ingredient. Registered crops, targets, rates and pre-harvest intervals follow the label approved in each market.
