Azoxystrobin Suspension Concentrate (Azoxystrobin SC) is a liquid fungicide formulation in which finely milled particles of the active ingredient Azoxystrobin are dispersed in water with the help of dispersing agents, wetting agents, and stabilizers. This formulation type ensures uniform suspension, high biological stability, and ease of application when diluted with water.
Azoxystrobin is a broad-spectrum, systemic and translaminar fungicide belonging to the strobilurin (QoI) chemical class, known for blocking mitochondrial respiration in fungi by inhibiting electron transport at the Qo site of complex III.
