From early 90s we have been observing that Aphelenchoides besseyi also, to affect tuberose badly in West Bengal as well as in other tuberose growing adjacent states. Interestingly, in most of the cases where tuberose is grown side by side or in sequence with rice, manifestation of symptoms is seen only in tuberose but not in rice. This made us curious to search the reasons behind, comparative preference of nematodes towards tuberose. We decided to go for biochemical analysis of both the plants. The experiment was carried out in the field from 2016 - 2017 at Central research farm of B.C.KV, Gayeshpur, W.B and Laboratory experiment done at college of agriculture at B.C.K.V, Mohanpur. Results of this experiment showed that, total protein, carbohydrate contents were found to be higher and silicon content was found to be lower in Tuberose when compared to rice, as protein and carbohydrate are essential for the nematode for its growth and development. Silicon helps to strengthen cells of rice leaf, stem, and roots. Silicon confers resistance to herbivores via physical and biochemical. Therefore, differential contents of these facets could have been a strong reason behind the inclination of preference to tuberose by the foliar nematodes.
