Biological Management of Fusarium Wilt in Chickpea (Cicer Arietinum L.) Caused by Fusarium oxysporum f. sp. ciceris

Abstract

In the present study, the three rhizobacterial strains (CPs3, CBs5 and Pf1) and fungal antagonists (CTs2 and Tv1) were evaluated against Fusarium wilt of chickpea under glasshouse and field conditions. Among all the treatments the strain CPs3 (Pseudomonas chlororaphis) has recorded highest germination (100%) and yield parameters viz., yield of 1194.4 kg/ ha with 13 (Number of pod bearing branches/plant), 32.3 (Pods/plant) and 33.0 g of 100 seeds weight with lowest incidence of wilt at 14.3% with disease reduction 80.7% (glasshouse) and 21.67% with 70.18% in the field conditions when compared to other biocontrol agents. The highest population of 8.2 x105 cfu/ g of soil and followed by Pf1 (Pseudomonas fluorescens) recorded 7.5 x105 cfu/g of soil. The strain CPs3 (Pseudomonas chlororaphis) had better growth promoting traits and management of the wilt disease in chickpea with superior root colonization ability.

Response of chickpea genotypes (Cicer arietinum L.) to the fungi complex that causes wilt

“…Diverse studies have conducted the search for sources of resistance to F. oxysporum s. l. (Rana et al, 2023), M. phaseolina (Mirchandani et al, 2023), S. rolfsii (Vishruta and Nath, 2021) and S. sclerotiorum (Mwape et al, 2021a) in genotypes of Cicer spp. ; however, only some genotypes of chickpea resistant to F. oxysporum s. l. (Rana et al, 2023) have been found.…”

(Rana et al, 2023) have been found. Therefore, there is a need to continue with the search for sources of resistance to the diverse fungi which originate in the soil that affect the chickpea crop, with the aim of including this resistance to the future chickpea varieties to develop in Mexico.…”

“…Among the main limitations in the production of this crop, there is root rotting and wilting caused by a fungi complex which originates in the soil, including Fusarium oxysporum, Macrophomina phaseolina, Sclerotium rolfsii and Sclerotinia sclerotiorum, and these depend on the moment of infection and the amount of inoculum in the soil, reducing production in up to 100% (Rai et al, 2022;Kamthe et al, 2023). Wilting caused by Fusarium is one of the most severe diseases in this crop, causing losses in yield of up to 100% under favorable conditions for the infection (Rana et al, 2023). The disease has been associated primarily with Fusarium oxysporum, although the phylogenetic evidence points to Fusarium oxysporum being a compound of cryptic species (Laurence et al, 2014).…”

“…ISSN 2477-9407 factores, destacando las enfermedades ocasionadas por diversos hongos fitopatógenos (Sankar et al, 2019). Fusarium oxysporum y F. solani son dos hongos que causan enfermedades en semillas y raíz de plantas de garbanzo y están considerados como fitopatógenos de importancia debido a su amplia distribución mundial y a las pérdidas que producen anualmente, dentro de los principales síntomas que ocasionan están las pudriciones y/o necrosis en la semilla o pudrición y/o necrosis de raíz y marchitamiento general que provocan la muerte de las plantas en vivero o campo (Sunkad et al, 2019).…”
