he effect of different dosages of thymol alone,iprodione alone and combinations of thymol and iprodioneon white rot disease of garlic and its impact on soilmicrobial community structure were investigated undergreenhouse conditions. Thymol alone or in combinationwith the fungicide iprodione did not appear to reduce eitherwhite rot incidence or soil sclerotia density as compared toan infected control. However, iprodione alone or in combination with thymol reduced soil fungal biomass. Inaddition, iprodione alone decreased soil microbial activityas estimated by fluorescein diacetate (FDA). Soil bacterialcommunity structure as estimated by phospholipid fattyacid (PLFA) profiles was also was affected by both thymoland iprodione applications. The correlation biplot of theindividual PLFAs and biocide treatment indicated that thetreatments with thymol alone increased cyclopropyl fattyacid (cy17:0 and cy19:0), while the treatments withiprodione alone increased some saturated and branchedfatty a
