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.
