Quantitative analysis of the effects of diffusates from plant roots on the hatching of Meloidogyne chitwoodi from young and senescing host plants

We analyzed the effects of diffusates from six different crops on the egg hatching of Meloidogyne chitwoodi collected from young and senescing tomato plants using a non-linear model. Diffusates only from tomato and carrot significantly delayed the hatching of eggs from young plants, but did not do so from senescing plants, suggesting that delay of hatching depends on the origin of diffusates and host plant age.
