The spread of epidemics is studied in an anisotropic network of three-dimensional bean roots placed on a square lattice. In particular, the effect of global anisotropy caused for example by an external resource field is analysed. It is demonstrated that global anisotropy leads to reduced resilience to epidemic invasion as compared with a similar system of roots in the absence of external field. The origin of this effect is suggested to be correlations in transmission of infection between pairs of roots.
