Abstract Th effect of fenvalerate 20% EC (a synthetic pyrethroid) on the growth of two ectomycorrhizal fungi, Thelephora terrestris and Laccaria laccata, was studied in vitro. In the case of T. terrestris, mycelial growth was promoted at lower concentrations of the insecticide but inhibited at higher concentrations; mycelial growth of L. laccata decreased with increase in concentration. The effect of the insecticide at three concentrations (0.25, 0.5, 1.5 ppm) was also studied on ectomycorrhizal formation in 4-month-old seedlings of Pinus patula in nursery trials. At lower concentrations the insecticide had no significant effect on mycorrhizal formation.
