Effect of pesticides on the growth of aquatic hyphomycetes.
The effect of two herbicides (paraquat and 2,4-dichlorophenoxybutyric acid) and two fungicides (mancozeb and captafol) was studied on the growth of Flagellospora penicillioides, Lunulospora curvula and Phalangispora constricta using the poisoned-food technique. The pesticides did not produce any inhibition of growth at concentrations up to 5 mg/l. The required concentration to bring about total inhibition of growth varied among the chemicals and the cultures. The herbicides produced a slight enhancement of culture growth at concentrations ranging from 1 to 25 mg/l.
