Abstract A field experiment was conducted at Horticultural Research Station of Bidhan Chandra Krishi Viswavidyalaya, Mondouri, Nadia with six treatment combinations under field conditions to test the efficacy of the treatments for managing foliar nematode (Aphelenchoides besseyi) problem in tuberose. The adoption of different management approaches significantly suppressed nematode attack on tuberose as compared to untreated plots. The nematodes infestation varied from 13 to 38% in the treated plots and 32 to 50% and 32 to 62% in farmers’ practice and untreated plots, respectively. The maximum infestation (62%), nematode population (mean population density 3,387/flower stalk) and lowest yield (mean 323 flower stalks/plot-1.5 x 1.8 m was recorded in the untreated plots. The Percent Disease Index (PDI) value was varied from 12 to 33% in the treated plots whereas in untreated plot as well as in farmers practice, it was ranging from 27 to 56%. Among the treatments, T1 was the best treatment which was followed by T2, T3, T4 and T5. Top Key words Tuberose, foliar nematode, Aphelenchoides besseyi, management, west Bengal. Top |
