Abstract: Two fungicides, Aliette and ThiovitJet @ 0.15%, containing Aluminum tris (O-ethyl phosphonate) and sulphur compounds, respectively; two plant extracts, Melia azedarach and Azadirachta indica @ 8% and one biocontrol agent, Trichoderma harzianum @ 107 conidia ml-1 were investigated against ascochyta blight of chickpea under field conditions. Treatments were evaluated on three varieties susceptible to chickpea blight. Field trial revealed that Aliette and ThiovitJet significantly decreased disease severity to 17 and 23% respectively, followed by M. azedarach and A. indica which decreased severity to 50 and 56% respectively, compared to control with 75% disease severity. T. harzianum, with a severity of 63%, was significantly less effective than fungicides and both plant extracts in controlling blight disease. The current research revealed that systemic and sulphur containing fungicides, both plant extracts and the biocontrol agent have the potential to control ascochyta blight of chickpea.
