Integrated management of Meloidogyne incognita‐Fusarium oxysporum f. sp. ciceri wilt disease complex in chickpea

Abstract

A field experiment was conducted to study the management of a root‐knot nematode, Meloidogyne incognita (Kofoid and White) Chitw. (Tylenchida: Heteroderidae)‐wilt inducing fungi, Fusarium oxysporum Schlecht. emend. Snyd & Hans. f. sp. ciceri (Padwick) Snyd. & Hans. (Moniliales: Tuberculariaceae) wilt disease complex in chickpea (Cicer arietinum L.). cv. Annegiri. The results indicated that integration of soil solarization (for 6 weeks), VA mycorrhizal fungus (VAM), Glomus fasciculatum inoculation (12g/hill) and seed treatment with carbosulfan (3% w/w) was highly effective in reducing population levels of both pathogens, root‐knotdisease and wilt incidence and in increasing chickpea grain yield significantly. However, seed treatment with carbendazim (0.25% w/w) together with carbosulfan (3% w/w) was not only effective in reducing the wilt disease complex but also economic with an incremental cost: benefit ratio of 1: 2.4.
