Antagonistic Activity and Shelf Life Study of Trichoderma harzianum (Rifai)

Antagonistic activity of Penicillium oxalicum Corrie and Thom, Penicillium decumbens Thom and Trichoderma harzianum Rifai isolates against fungi, bacteria and insects in vitro.

The antibiotic activity of 70 isolates belonging to the genera Aspergillus, Penicillium, Fusarium, Alternaria and Trichoderma was tested as preliminary screening. The highest activity was obtained with three Penicillium oxalicum isolates, one Penicillium decumbens isolate and the Trichoderma harzianum isolate. After that, we chose these five isolates in order to carry out other studies with bac...

Testing of an Antitumor Enzyme L-lysine-A-oxidase from Trichoderma Harzianum Rifai F-180

An enzyme L-lysine-A-oxidase has been obtained from Trichoderma harzianum Rifai F-180. The analysis of serum from CBA mice immunized five times with native L-lysine-A-oxidase intravenously, at a dose of 35 U/kg, showed that the preparation had virtually no effect on the immune response to Tdependent antigen. L-lysine-A-oxidase at a dose of 35 U/kg administered twice intradermally has no effect ...

بررسی امکان کنترل بیولوژیک بیماری مرگ گیاه‌چه چغندرقند به‌وسیله جدایه‌هایی از Trichoderma harzianum Rifai

 با توجه به قدرت بالای آنتاگونیستی قارچTrichoderma harzianum ، پنج جدایه T.h.K، T.h.BI، T.h.Mo، Var33  و تربت VI انتخاب و اثر آن در شرایط آزمایشگاه و گلخانه بر بیمارى مرگ گیاه‌چه چغندرقند ناشى ازRhizoctonia solani  مطالعه شد. قدرت آنتاگونیستی جدایه‌هاى T. harzianum به‌صورت کشت دو طرفه روى PDA در کشت همزمان، کشت 48 ساعته و 96 ساعتهR. solani  بررسى شد و مشخص شد کلیه  جدایه‌های T. harzianum می‌توا...

effect of different organic substrates and carbon and nitrogen sources on growth and shelf life of trichoderma harzianum

nine organic substrates viz., rice grains, sorghum grains, wheat grains, millet grains, wheat straw, rice husk, cow dung, sawdust, and poultry manure were used for mass multiplication of trichoderma harzianum. of these,sorghum grains followed by millet grains were the best substrates. the poultry manure appeared to be the most unsuitable substrate, whereas rice grains, wheat grains, wheat straw...
