المكافحة الأحيائية لمرض تعفن جذور الحمص المتسبب عن الفطر Fusarium solani باستخدام المستحضر الحيوي Biocont-T في الحقل

Abstract EN

A field study was conducted in the Girdarasha station (8.8 Km.

south of Erbil), College of Agriculture, Salahaddin University, Erbil Province, Kurdistan Region, Iraq.

The study objective was to determine the efficiency of the commercial biological formulation of Trichoderma harzianum (Biocont-T) in reducing the infection severity with chickpea root rot caused by Fusarium solani and its ability to improve plant growth and yield.

Results revealed the significant effect of the biological agent in reducing infection severity (18.33-22%) compared to control (26.67%).

However, there was no significant effect on plant growth characteristics except the foliage length which was 30.80-35.03 cm compared to control (25.57 cm).

Results of all yield components (biological yield, seed yield, weight of 100 seed, and reduction of the percentage of damaged and atrophied seeds) were significantly increased.

The best treatment was applying peat moss supported with Trichoderma harzianum prepared from the biological formula Biocont-T at the rate of 5% and 10% (W/W), or with a combination of 10g Biocont-T + 500 g peat moss/treatment
