Slight induction and strong inhibition of hatching by short-chain molecules released by different plant species.

New management tools are necessary to reduce the damage caused by the soybean cyst nematode (SCN), . Identification of molecules that can stimulate second-stage juveniles (J2) hatching in an environment without food may contribute to that. In in vitro experiments, we evaluate the effect of volatile organic compounds (VOCs) released by soybean (), bean (), ryegrass (), and alfalfa () on egg hatching.

Volatile organic compounds produced by castor bean cake incorporated into the soil exhibit toxic activity against Meloidogyne incognita.

Background: This study showed, for the first time, the effect of volatile organic compounds (VOCs) emitted by castor bean cake added to soil on the plant-parasitic nematode Meloidogyne incognita. Identification of nematotoxic volatiles increases the chance of identifying molecules for use in commercial nematicides.

Results: VOCs produced after the incorporation of castor bean cake in the soil resulted in immobility (>97.
