چکیده مقاله :
اثر چهار قارچ کنترل کنندهTrichoderma hamatum, Trichoderma harzianum, Trichoderma viride, Gliocladium virens و دو باکتری کنترل کننده Pseudomonas fluorescens و Bacillus subtilis روی قارچ عامل بیماری پژمردگی آوندی نخود ایرانی (Fusarium oxysporum f.sp. ciceri) در شرایط آزمایشگاهی مورد بررسی قرار گرفت. در بین قارچهای کنترل کننده، T. harzianum با 17 میلیمتر حداکثر کاهش در مقایسه با 7 میلیمتر توسط T. hamatum کمترین کاهش در رشد عامل بیماری گزارش گردید. از لحاظ آماری میزان کاهندگی / کنترل کنندگی رشد قارچ عامل بیماری پژمردگی نخود در بین دو باکتری مورد استفاده در آزمایش تفاوت معناداری مشاهده نگردید. در شرایط مزرعه قارچهای T. harzianum وG. virens وباکتری P. fluorescens که به فرم ماده افزودنی پودر تالک استفاده گردیدند کاهش قابل توجه ای از لحاظ بیماری پژمردگی نخود در مقایسه با تیمار شاهد ایجاد کردند.
The efficacy of four fungal bioagents viz., Trichoderma hamatum, Trichoderma harzianum, Trichoderma viride, Gliocladium virens and two bacterial bioagents namely Pseudomonas fluorescens and Bacillus subtilis were evaluated against the chickpea vascular wilt pathogen, Fusarium oxysporum f.sp. ciceri in vitro condition using Dual Culture Technique. Among the fungal bioagents, T. harzianum produced the maximum inhibition zone of 17 mm compared to the minimum of 7 mm by T. hamatum. There was no significant difference between the inhibition zones produced by P. fluorescens and B. subtilis. Soil application of talc- based formulation of T. harzianum, P. fluorescens and G. virens effectively controlled the vascular wilt of chickpea under field condition.
