Abstract
AbstractDalapon and diuron are two common herbicides used for the control of weeds. A study of the response of Gliocladium virens, Trichoderma hamatum and T. koningii in cultures to the herbicides was carried out. Changes in fungal colony morphology and growth and sporulation rates in the presence of up to 105 mg herbicide litre−1 were monitored. The three fungi were not adversely affected at a concentration of 103 mg litre−1. Changes in colony morphology and decreases in growth and sporulation rates were evident at the maximum test concentration (105 mg litre−1) of both herbicides. These generally recovered when the fungi were replated in the absence of the herbicides.
