Collar rot (Sclerotium rolfsii) of chickpea (Cicer arietinum) is one of the devastating soil-borne diseases of fungal origin, due to which 10-30% yield loss is recorded annually according to severity of the disease. Management of collar rot of chickpea is not feasible in the absence of effective soil fungicides. However, Trichoderma harzianum and plant growth promoting rhizobacteria (PGPR) have shown high efficacy against this disease in vitro as well as in the field. We used T. harzianum (104, 106 and 108 spore/ml) and two PGPRs (Pseudomonas fluorescens strain 4 and P. aeruginosa) as foliar spray with the fresh and heat inactivated microorganisms. Foliar application of T. harzianum (108 spore/ml) and P. fluorescens strain 4 (108 cfu/ml) showed maximum efficacy in reducing plant mortality as compared to the control. Foliar application of fresh-and heat-inactivated (121°C for 10 min) P. fluorescens strain 4, and T. harzianum reduced 15-25% plant mortality but P. aeruginosa showed very little disease control of 10-15%. However, regarding plant growth promotion, it was observed that fresh-and heat-inactivated P. fluorescens strain 4 showed maximum efficacy followed by fresh and heat inactivated P. aeruginosa and T. harzianum as compared to the control. The disease-controlling efficacy was also associated with the increase in phenolic acid synthesis in chickpea plants. The control of chickpea collar rot by biocontrol agents is safe and ecologically sound and appears to be a healthy approach to the disease control.

Zgnilizna szyjki korzeniowej (Sclerotium rolfsii) ciecierzycy pospolitej (Cicer arietinum) jest jedną z groźnych chorób przenoszących się poprzez glebę, która powoduje straty plonu wynoszące 10 do 30%, w zależności od jej nasilenia. Choroby tej nie można zwalczyć przy braku fungicydów przeznaczonych do doglebowego stosowania. W przeprowadzonych badaniach wykazano jednak, że zużycie do opryskiwania liści roślin grzyba Trichoderma harzianum lub dwóch gatunków bakterii rizosferowych stymulująch wzrost roślin, a mianowicie Pseudomonas fluorescens szczep 4 lub P. aeruginosa wykazuje maksymalną skuteczność ograniczania śmiertelności roślin w porównaniu do roślin z nietraktowanej kombinacji kontrolnej. Zastosowanie do opryskiwania liści żywych lub inaktywowanych wysoką temperaturą (121°C w ciagu 10 min.) bakterii P. fluorescens szczep 4 albo grzyba T. harzianum, zmniejszyło śmiertelność roślin o 15-25%, ale bakterie P. aeruginosa ograniczały chorobę w niewielkim stopniu. Biorąc pod uwagę stymulację wzrostu roślin zaobserwowano, że żywe oraz inaktywowane termicznie bakterie P. fluorescens szczep 4, wykazywały najwyższą skuteczność w porównianiu do żywych i inaktywowanych termicznie bakterii P. aeruginosa oraz grzyba T. harzianum. Skuteczność zwalczania choroby była także związana ze wzrostem syntezy w roślinach ciecierzycy kwasu fenolowego.
