Abstract

A field experiments was conducted at Horticultural Research Station of Bidhan Chandra Krishi Viswavidyalaya, Mondouri, Nadia with two treatments viz. treated i.e. pre-soaking of bulbs in plain water for overnight + hot-water treatment at 50°C for 30 min. + three sprayings with monocrotophos 36 SL at 500 ppm at 15 days interval (repeated the same spraying in second year from March onwards) and untreated control plots(1.5x1.8m2) with ten replications to estimate the yield losses caused by the foliar nematode in tuberose under field situations. Experimental results showed that the treated plot had low nematode infestation (26%) and PDI value (25%), reduction (53%) of nematode population and higher spike yield (mean 286/plot) as compared to untreated plots (mean 207/plot). With the adoption of nematode management practice, spike yield could be saved up to 38% and that could be to the extent of 59% when loose flower yield/plot was taken in consideration.
