Abstract
The efficacy of three synthetic nematicides namely, D-D (mixture of 1, 2-dichloropropane and 1, 3-dichloropropene), carbofuran and sodium azide, and oil cakes of mustard (Brassica campestris) and cotton seeds (Gossypium hirsutum) for controlling root-knot nematode (Meloidogyne incognita) on potato (Sokznum tuberosum) seedlings raised from true potato seeds (TPS) were evaluated with pot experiments. Nematode infested soil was treated with D-D at 0, 0.05, 0.10 and 0.15 ml/kg, and sodium azide at 0, 25, 50, and 75 mg/kg soil 2 weeks before sowing. Carbofuran was applied at 0, 0.0450, 0.0675 and 0.0900 mg/kg soil 2 hr before sowing. Oil cakes of mustard and cotton seeds were mixed with the soil at 0, 0.25, 0.50 and 1.0% (w/w) and allowed to decompose for 2 weeks before sowing. Twenty five TPS were sown in each pot under all experiments. Seven days after germination seedlings were thinned and 10 plants/pot were allowed to grow for 6 weeks. Data on plant growth and severity of root-knot were recorded. It was found that treatment of soil with the nematicides and oil cakes gave significant reduction in gall indices and in numbers of galls and females in roots. Higher dosage corresponded to better control of the disease. Complete elimination of root-knot was achieved with only the treatment with highest dosage of sodium azide. Except sodium azide all treatments with other two chemicals and oil cakes improved plant growth in terms of shoot and root weight significantly. * Values are averages of 4 replications ; those within the same column with a common letter do not differ significantly (P=O.O5). ** Based on a O-10 scale DISCUSSION D-D was found to be an effective nematicide to control root knot and to improve growth of seedlings but no treatment gave complete elimination of the disease.
