General description

Isoxaflutole is a novel pre-emergence herbicide widely employed for the protection of corn and sugarcane against broadleaf and grass weeds. Its mode of action involves the facilitation of characteristic foliar bleaching activity in target species preceding the plant death.

Application

Isoxaflutole may be used as an analytical reference standard for the determination of the analyte in blackcurrants and soya grain by gas chromatography-tandem mass spectrometry (GC-MS/MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS), respectively.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

A field lysimeter study with bare ground and five different ground covers was established to evaluate the effect of forage grasses on the fate and transport of two herbicides in leachate. The herbicides were atrazine (ATR; 2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) and isoxaflutole [IXF;

Sorption largely controls pesticide fate in soils because it influences its availability for biodegradation or transport in the soil water. In this study, variability of sorption and desorption of isoxaflutole (IFT) and its active metabolite diketonitrile (DKN) was investigated under
