Integrated Management of Nematode Disease Complex in Tuberose (Polianthes tuberose L)

The present study on management practices for control of nematode disease complex was conducted by ICAR-Krishi Vigyan Kendra, Thirupathisaram in Kharif season during 2018–19 at 10 farmers fields in Thovalai block of Kanyakumari district on an area of 4 ha comprising 0.4ha each. Integrated management practices were bulb treatment @ 20 g/kg of bulb each with Paecilomyces lilacinus + Trichoderma viride + Pseudomonas fluorescens, followed by soil application with P lilacinus + T viride + P fluorescens @ 5 kg/ha enriched with FYM (1t) on 30th day after planting followed by foliar application of P lilacinus + T viride + P fluorescens at 30 d intervals @ 5g/l on 60, 90 and 120^th day after planting was demonstrated in farmers field for the management of nematode disease complex. The results revealed 55.8 percent reduction in root knot nematode incidence and 75 per cent reduction in wilt incidence in tuberose in demo fields compared to farmers practice. 20.97 per cent increase in the yield was recorded in demonstration plots and the quality of flowers was better in demonstration plots.
