Description
	This study was to determine the concentration of active ingredient and the volume of pesticides in commercial products. The limit of percentage of active ingredient was based on FAO recommendation. The actual volume was measured and compared with the label. Three groups of pesticides, cypermethrin, monocrotophos and mevinphos were analyzed by gas chromatography. Ten from twelve brands of cypermethrin contained the active ingredient within FAO limit but the exact volume of all brands were less than the labelled amount. Only
one out of eleven brands of monocrotophos had the active ingredient within the FAO limit (98.70%). The other average contents were only 58.40% of the label (0-86.23%). Two of these products had the same volume as the label. For mevinphos, twelve brands were analyzed. Only one contained the active ingredient in the limit (98.96%). The average concentrations of the others were 76.12% of the label (0-93.38%). None of these satisfied the volume labelled. It was concluded that these commercial pesticides contained less active ingredient and volume than the declared amount on the label.
