The interaction of sulphur dioxide (0.2 ppm) and seed gall nematode, Anguina tritici, was observed on five wheat varieties (LOK-1, HD-2329, Raj-3765, PPW-154, UP-2328) in artificial condition. SO2 alone significantly reduced plant growth of all the varieties. Reduction in growth was more in nematode inoculated and exposed to SO2 sets as compared to nematode alone-inoculated sets. However, highest reduction in yield was observed in nematode alone-inoculated sets. Numbers of cockles varied from variety to variety in nematode alone-inoculated sets. However, none or few cockles were formed when nematode inoculated plants were exposed to SO2. The antagonistic interaction was observed between nematode and SO2 when both combined together.
