Management of root-knot nematode, Meloidogyne incognita and soil borne fungus, Fusarium oxysporum in cucumber using three bioagents under polyhouse conditions

Complex diseases caused by Meloidogyne incognita and Fusarium fungus in cucumber is the most destructive disease under polyhouses. The experiment was conducted in the polyhouse of the Department of Horticulture, CCS HAU, Hisar, Haryana, India during summer season (2015–16) to evaluate the potential...

The experiment was conducted in the polyhouse of the Department of Horticulture, CCS HAU, Hisar, Haryana, India during summer season (2015–16) to evaluate the potential of bacterial and fungal biocontrol agents against Meloidogyne incognita and Fusarium oxysporum f. sp. cucumerinum in cucumber. Bioagents - Trichoderma viride (Tv), Pseudomonas fluorescence (Pf), Purpureocillium lilacinum (Pl) were taken 10 and 20 g kg−1 seed and bioagents liquid formulation, 10- and 15-ml kg−1 seed, were mixed with the potted soil. Chemical as well as untreated check were also maintained. All the treatments significantly improved the plant growth parameter, viz., shoot length (SL), root length (RL), fresh shoot weight (FSW), fresh root weight (FRW), dry shoot weight (DSW) and dry root weight (DRW) as compared to untreated check. However, significant reduction in nematode population and maximum improvement in plant growth parameter was recorded with carbofuran followed by higher dose of bioagents liquid formulation. Among the bioagents, bioagents liquid formulation was most effective in suppressing root knot nematode galling (43 / root system) and final population in soil (131 J2s / 200 cc soil) and fungus wilt incidence (25 %) at 30th day of after germination and significantly improved the plant growth parameters - shoot length (147.3 cm), fresh shoot weight (55.6 g), dry shoot weight (22.51 g) and dry root weight (4.50 g) from other bioagents. Bioagents liquid formulation was effective in suppression of root-knot nematode and fungus complex disease than the powder formulations of bioagents.
