| Background Root-knot nematodes in general and , in particular, are pests that cause agricultural losses. Currently, nematode control relies on chemical nematicides, which are hazardous to the environment and human health. The increasing demand for ecofriendly nematicides has prompted researchers to look into biocontrol agents that act as efficient and long-lasting alternatives to the currently used chemicals. Objective The aim of the study was to evaluate the in-vitro nematicidal activity of eight mushroom (, , , , , , , and ) extracts against juveniles and eggs. Materials and methods Hydromethanolic extracts were prepared from the fruiting bodies of mushrooms under investigation. Then the obtained extracts were evaluated for their in-vitro nematicidal activity against juveniles’ second stage after 24, 48, and 72 h of treatment, also against their eggs. Results and conclusion All tested mushroom extracts were capable of inducing mortality in second stage juveniles with mortality percentages ranging from 79.3 to 97%. On the other hand, the tested mushroom extracts exhibited some nematostatic and nematicidal activity against eggs as compared with the control after 7 days using 80 µl/ml concentration. The tested mushroom extracts caused suppression in eggs hatching with inhibition rates that ranged from 59.38 to 81.25%. hydromethanolic extract showed the highest inhibition as compared with the control and other tested mushroom extracts as it caused a relative suppression that reached 81.25% against eggs after 7 days of exposure. The same mushroom extract has achieved a juveniles mortality of 97%. extract is nominated as a potential nematicidal agent. Further studies are required to confirm the potency of this extract and analyze its chemical profile. | ||
