Wallace has studied ecology of soil nematodes and its bearing on disease. He discovered precise concepts which explained numbers and distribution of nematodes in soil and he devised a model for locomotion of nematodes of some general application. Work on foliar nematodes produced an explanation of the infective process which made possible the control of the disease; similar work was conducted with root-knot nematodes. 

He has shown that plants have compensatory mechanisms for maintaining health and that they may over-compensate at low levels of infection. He has skilfully used methods of partial regression to analyse host-parasite-environment interactions and is at present examining disease in the field using step-wise regression analysis.
