Abstract

Brinjal (Solanum melongena) crop output is significantly affected by root-knot nematodes, particularly Meloidogyne incognita. Root-galls of brinjal produced by Meloidogyne incognita can be efficiently suppressed by applying botanicals, which boosts yield and plant growth. Experimental was carried out of evaluation of botanicals for the management of root-knot nematode, Meloidogyne incognita (Kofoid and White 1919) Chitwood, 1949 on Brinjal, efficacy of botanicals viz., Tulsi, Pyrethrum, Datura, Ashwagandha and Congress grass were added to soil each @ 2.5 and 5 gm per kg soil. Plants were harvested after 60 days of transplanting and the observations on plant growth characters viz., shoot length, shoot weight, root length, root weight and nematode reproduction viz., No. of galls/ plant, No. of egg masses/plant, No. of egg and larvae/ egg mass, nematode juvenile/ 200 cc soil and total nematode population in soil were recorded. Soil application of Datura @ 5 gm/kg soil was found superior treatment, whereas shoot length (41.90 cm), shoot weight (31.40gm), root length (32.70cm), root weight (3.85gm) and nematode reproduction viz., No. of galls/ plant (19.00), No. of egg masses/plant (13.00), No. of egg and larvae/ egg mass (75.00), nematode juvenile/ 200 cc soil (289.00) and total nematode population in soil (3865.00), respectively, followed by Pyrethrum @ 5 gm/kg soil and Congress grass @ 5 gm/kg soil in improving plant growth of brinjal and reducing reproduction of root knot nematode.

Conclusion

Results of soil application trial with leaves powder of Datura (Datura stramonium) @ 5 gm/kg soil, Pyrethrum (Chrysanthemum cinerarieaefolium) @ 5 gm/kg soiland Congress grass (Parthenium hysterophorus) @ 5 gm/kg soilwere effective for improving the growth of brinjal and reducing infection and reproduction of root knot nematode, Meloidogyne incognita. The effect of botanicals in brinjal crop infested with root-knot nematode, M. incognita. Results showed that application of datura was found to be the best treatment to enhance plant growth characters and minimum nematode reproduction @ 5gm/kg soil.
