The use of good quality pesticides is very crucial in agricultural production as the harms of pesticides to environment, soil, water and non-target species are well known. Use of poor quality pesticides magnifies the issues. Current survey was conducted to check and compared the quality of pesticides available in the market supplied by generic and multinational companies. Data was collected from the Pesticide Quality Control Laboratory Multan. For physical and chemical analysis gas chromatography (GC), high-performance liquid chromatography (HPLC), chemical digestion, Spectrophotometry and titration described by Collaborative International Pesticides Analytical Council. Results confirmed that 96.21% (10353) of total 10766 samples met the quality standards and about 3.77% (411) samples were declared unfit for applications to field crops. As compared to unfit samples of 2015-16, 1.59% increase was observed in the unfit samples of pesticides in 2017-18. Vehari was at the top of the list where an unfit sample was maximum in 2017-18. However, highest number was fit samples were noted in 2017-18 in Layyah. The comparison of branded and generic unfit pesticide samples revealed that branded unfit samples were 6 to 7 times less than generic unfit samples. In conclusion the maintenance of good quality by multinational companies as compared to the generic units in South Punjab.
