Augmentation of antagonistic effect of some bioagents against fungi causing pepper fruit rot by gamma radiation [electronic resource]. زيادة المقاومة البيولوجية لبعض الميكروبات ضد الفطريات المسببة لعفن ثمار الفلفل باستخدام أشعة جاما. p.2033-2047. Includes references. The effect of some biological control agents on the growth of seven isolates of the most frequent isolated pathogens from fruit rot of pepper, i.e. 3 isolates of Fusarium, 2 isolates of Alternaria and 2 isolates of Aspergillus were studied under laboratory conditions. Eight isolates of Trichoderma spp and one isolate of Bacillus subtilis were used for determination of the antagonistic activities against fungal pathogens in dual culture laboratory conditions. Three parameters were measured for antagonistic activities, i.e. linear growth and reduction of fungal growth under stress of bioagent, as well as over growth and/or inhibition zone. B. subtilis, Trichoderma hamatum, T. harzianum and T. viride were found to be the most potent biocontrol agents against most of the pathogens. The antagonistic effect was increased after irradiation of B. subtilis to radiation dose of 1 kGy and irradiation of Trichoderma sp. to a dose of 0.2 kGy. Summary in Arabic.
