Bioaugmentation, a new and efficient bioremediation technology, has unique advantages in the treatment of contaminated soils. In view of the current situation of pesticides-contaminated soils, this paper introduces the bioaugmentation and its application in degrading pesticides and analyzes the biotic and abiotic factors that influence bioaugmentation. Special attention is paid to research progresses and application of bioaugmentation in the remediation of the soils contaminated by organochlorinated, organophosphorus, pyrethroids and triazine pesticides. The countermeasures to the problems of bioaugmentation as well as the further research direction are put forward.
