Paraquat effect on the bacterial strains was evaluated by agar diffusion test using filter paper discs 5 mm in diameter.

Paraquat is often used in science to catalyze the formation of reactive oxygen species ROSmore specifically, the superoxide free radical.


Effect of some commonly used herbicides on soil microbial population. One example is the “double knock” system used in Australia. J Environ Earth Sci ; 6: Crit Rev Microbiol ; 5: J Herbisid Sci ; Volume 2 – In the agar diffusion method, the bacterial strains were inhibited by paraquat, in which the inhibition zone was wider with the increase of paraquat concentration Fig. N-acetylcysteine delays the infiltration of inflammatory cells into the lungs of paraquat-intoxicated rats.
