  • Title: Total bacterial and fungal population after chlorpyrifos and quinalphos treatments in groundnut (Arachis hypogaea L.) soil.
    Author: Pandey S, Singh DK.
    Journal: Chemosphere; 2004 Apr; 55(2):197-205. PubMed ID: 14761692.
    Abstract:
    Short-term inhibitory effect on the total bacterial population was observed after chlorpyrifos and quinalphos applications in the groundnut fields, which recovered within 60 days after seed treatment and by 45 days of soil treatment. The fungal population was significantly enhanced after chlorpyrifos treatment whereas quinalphos inhibited the fungal population during the initial days of treatment but no effect was observed after 60 days of treatment. The residues of chlorpyrifos and quinalphos in the treated soil were not persistent and their half-lives ranged from 7.0 to 9.2 days and 13.2 to 20.6 days, respectively.
