Abstract:

Interaction between wilt, root rot and root knot complex in lentil was evaluated and formulated its management strategies. Population of plant parasitic nematodes in rhizosphere was observed as pre - and post- sowing of of lentil and found that when variety K-75 was grown, the population of Meloidogyne sp. was increased to be 950, 1000, 1550, after 30, 60 and 90 days, respectively as compared to population 450, in case of essential population before growing of crop. Whereas the population in the rhizosphere of VL-516 was 600, 1750 and 2550, respectively, in 30, 60 and 90 days after sowing in compare to 450 of initial population before growing different varieties of lentil. Pathogenic ability of different inoculums levels of Meliodogyne incognita on plant growth was studies and showed that severe reduction of length at 5000 level of juvenile was 9 cm in comparison of check (14.57 cm), there was gradual reduction was observed. The reduction in root length was also higher at 5000 larval level in comparison of check. Reduction in shoot weight was also present with increasing order of larval population with reduction of 0.80 g, 0.65 g, 0.44 g and 0.23 g on level of 100, 500, 1000 and 5000 inoculums level, respectively. The results in respect of reactions of different lentil varieties against root-knot nematode and observed that variety NDL-9302, showed maximum shoot length (33.00 cm) and root length (8.55 cm) followed by VL-519 (8.15 cm) recorded, whereas minimum shoot length in (10.00 cm) and root length (3.15 cm) was observed with variety RLG- 101. The cultivar RLG-101 also exhibited maximum number of root galls/root system (115), and root-knot index (5.00). There was nematode population was recorded highest under cultivar of RLG- 101 (515) and minimum was observed in VL-1 (80.20). Interaction between Meloidogyne incognita with Fusarium oxysporum f. sp. lentis and Rhizoctonia solani showed that decreased shoot (10.18 cm)and root length (2.17 cm), decreased fresh weight of shoot (4.46 gm)and root length (0.86 gm), increased the no. of root galls/plant (70.00), reduced the number of rhizobium nodules/plant (9.30), increased root-knot index (4.00) and Nematode population (45.00) and highest wilting percentage (46.43 %) per 200 g soil. The effect of combination of thiram + bavistin + vitavax + carbosulfan + nemarin results highest shoot length (39.87 cm), fresh shoot weight (10.70 g), lowest for root-knot index (0.95), decreased the number of root galls/plant (21.12), increased the number of rhizobium nodules/plant (50.00) and lowest nematode larvae (15.13).
