Biomanagement of disease complex of Meloidogyne incognita and Fusarium oxysporum f sp ciceri on chickpea Cicer arientinum Butler 1918

Abstract

In the present study on the interaction of Meloidogyne incognita and Fusarium newlineoxysporum f.sp ciceri on chickpea, the result indicated that dual inoculation treatments newlinesignificantly decreased plant growth parameters over the treatment with M. incognita newlineat1000 J2/kg soil and F. oxysporum at 2% (w/w). The treatment with M. incognita at1000 newlineJ2/kg soil + F. oxysporum at 2% (w/w) after 15 days of inoculation was statistically superior newlinein decreasing the plant growth parameters of chickpea. However, number of galls, newlineeggmasses, final nematode population was found maximum in single inoculation treatment newlinethan dual inoculation treatments. The highest number of galls, eggmasses, final nematode newlinepopulation were observed in the treatment with M. incognita at1000 J2/kg soil. The newlinemaximum disease incidence was recorded in the treatment with M. incognita at1000 J2/kg newlinesoil and F. oxysporum at 2% (w/w) after 15 days of inoculation. newlineStudies on the management of disease complex of Meloidogyne incognita and Fusarium newlineoxysporum on chickpea with microbial consortia, vermicompost and Glomus fasiculatum newlinealone or in combination under microplot condition showed that all the treatments differed newlinesignificantly over untreated control in respect of increaseing plant growth parameters and newlineyield of chickpea. The seed treatment with microbial consortia at 5ml/l + soil application newlineof vermicompost enriched microbial consortia at 2t/ha + seed treatment with microbial newlineconsortia at 5ml/l + soil application of Glomus fasciculatum spores/m2 was found to be most newlineeffective in increasing plant growth parameters, yield, N,P, and K content in soil. All the newlinetreatment significantly decreased the number of galls, eggmasses, nematode population and newlinefungal population in soil and percent disease incidence. newlineIn the pilot field trial, conducted at farmers field with the best treatment combination newlinefound under microplot trial for the management of disease complex of Meloidogyne newlineincognita and Fusarium oxysporum on chickpea showed that the seed treatment with newlinemicrobial consortia at 5m...
