Azoxystrobin
Overview
Azoxystrobin is one of strobilurin fungicides synthesized from materials derived from basidiomycetes. It is used for multiple farm products as pesticide because of its strong fungicidal activity to a variety of fungi. This kit allows an easy, rapid (within 2 hours), sensitive, quantitative, multi-sample analysis of azoxystrobin that remains in farm products or in the environment. This kit is best applied for inspection at delivery time/prior to processing or primary screening in production sites.
Features
Comparison with instrumental analysis
While instrumental analysis offers high accuracy, it requires complicated and time-consuming pretreatment techniques, and sophisticated instrument operation as well as large quantities of acetone, hexane or acetic ether as organic solvents. The simpler pretreatment required for kit saves significant time. Additionally, only a small quantity of methanol is required as an extraction solvent for analyzing azoxystrobin.
Main application example
The figures show the comparison between standard curves with 10% methanol and reaction curves drawn with methanol extract of azoxystrobin-added farm products (diluted to 10% methanol equivalent). The overlapping curves; demonstrate the suitability of this kit for analyzing trace azoxystrobin without any interference from the original produce.
