Chickpea (
Cicer arietinum L.) is a major crop of semi-arid regions
(Imtiaz et al., 2011) of the world. It is cultivated for its protein-rich (19% to 25%) seeds. Moreover, pods are lush in fiber, minerals, β-carotene and unsaturated fatty acids
(Jukanti et al., 2012). It is a cool season legume crop ranking second in global production among food legumes with a global production of 15.87 mt from an area of 15.0 m ha. South Asia is the largest producer and consumer of chickpea that contributes about 90% of area globally. Production share of chickpea by Asian region includes 84.9% followed by Americas and Africa, each with 4.6%. Mediterranean region, India, Turkey, Pakistan, Australia and Myanmar are the key producers
(FAOSTAT, 2021). The states of Maharashtra, Madhya Pradesh, Rajasthan, Karnataka, Uttar Pradesh and Gujarat produce the most of the chickpea in India. In India, about 104.74 lakh ha, area coverage has been reported under chickpea cultivation during
rabi 2023-24 with a production of 122.67 lakhs tons (
Anonymous, 2024). Key districts in Telangana that grow chickpea include Adilabad (29,076 ha), Kama Reddy (64,552 ha), Nirmal (23,836 ha), Nizamabad (7,689 ha), Sangareddy (6,492 ha) and Vikarabad (2,803 ha). The crop is being grown in an area of 1.48 lakh ha during
rabi season with a production of 2.32 lakh tons and with a productivity of 1568 kg ha-1 (
Anonymous, 2024). Both biotic (
Ghosh et al., 2016, 2017) and abiotic
(Palit et al., 2020) stresses were recognized as key barriers to chickpea production resulting in decreased yields. Among the biotic factors,
Fusarium wilt has historically been the most common disease which can cause considerable problem.
Fusarium is a highly complex and adaptive genus of
Eumycota, in particular and has both pathogenic and non-pathogenic strains that can harm plants, animals and humans (
Bodah, 2017). Besides causing large pre- and post-harvest losses, several
Fusarium species create toxins to foods as well as crops
(Nayaka et al., 2008; 2009;
Mudili et al., 2014). These are contaminants found in cereal-based diets and other grains and they are known to cause a variety of ailments in organisms
(Venkataramana et al., 2014; Divakara et al., 2014; Kalagatur et al., 2015; Kumar et al., 2016). Nevertheless, the prevalence and spread of pathogen have shifted significantly over the last decade, as has the emergence of novel and previously identified pathogens (
Sharma and Ghosh, 2017;
Chobe et al., 2020). Infected chickpea plants show a variety of symptoms, including reduced development at the seedling stage, followed by tips, fall off of twigs and leaves of mature plants. Even when there is no obvious degradation, these plants exhibit dark brown staining in the xylem (
Pande and Sharma, 2012). Highly vulnerable varieties frequently develop symptoms within 25 days after planting. Initial wilting causes huge losses than late, with wilted plant pods being lighter than healthy ones. Yield losses of 10% to 100% have been observed, on agroclimatic conditions and varietal susceptibility
(Warda et al., 2017). During
rabi (November-March, 2022-23), an investigation was undertaken to identify, purify and analyse the pathogenicity of
Fusarium (Srinivas et al., 2024). The prevalence of the disease across all surveyed districts, with varying degrees of severity. Surveys was undertaken over several decades suggest that the disease is common in major regions such as Asia, Africa, Americas. These surveys recorded varied disease prevalence and severity, which frequently resulted in large yield losses
(Pande et al., 2010). The overall sag episode was higher in
rabi season of 2018-2019 compared to the following season,
rabi 2019-2020. Across all six districts surveyed, the disease exhibited a widespread and consistent presence with a moderate to severe incidence (
Shrivastava and Dhakad, 2021).
Mahajan et al., (2023) performed monthly surveys throughout several chickpea-growing locations in the Jammu subtropics. The total disease incidence was 15.64% in 2016-17 and 16.86% in 2017-18. Numerous studies showed that plants react differently to combination stressors than to individual stressors, activating unique gene expressions according to the environmental conditions faced. Abiotic stress often alters plant vulnerability to biotic pests or diseases rather than adding to the problems (
Sharma and Ghosh, 2017;
Tarafdar et al., 2018). The research work was done to better understand disease development pathways, to mitigate yield losses and ensure food availability for vulnerable populations.
