Potatoes flutolanil

The major metabolic pathways of flutolanil in plants are para-hydroxylation of the aniline ring and hydr-oxylation of the isopropoxy side chain. For potatoes, flutolanil anddesisopropyl-flutolanil (M-4) are selected as the target analytes. For rice plant, other metabolites containing 2-(trifluoromethyl)benzanilide moiety are also selected as the target analytes. For soil and water samples, flutolanil is selected as the only target analyte. 

Four different types of residue analytical methods of flutolanil and its metabolites are developed for plant (potato and rice), soil and water ... 

With fortification levels of 0.01-0.1 mg kg average recoveries of flutolanil and the metabolite M-4 from untreated potato are 80 and 76%, respectively. 

Calculate the concentrations of the analytes (flutolanil and M-4) in potato samples (mg kg ) with the following equation ...

Other diseases of potatoes are mainly seed-borne and can be corrtrolled by treating seed with fungicides, e.g. imazalil, flutolanil, and pencycuron. They include gangrene, silver scurf, dry rot, skin spot and stem canker (Table 6.2).
