blight, caused by mycosphaerella rabiei is the most important disease of chickpea in iran. in order to find a method for the biological control of the disease, the inhibitory effect of 36 isolates of three species, trichoderma harzianum, t. virens and t. atroviride, on a most virulent isolate of the pathogen, in hyperparasitism, dual culture, and production of volatile antibiotic compounds were...

During 2003-04 major mushroom production units of Tehran province were sampled and 103 fungicolous isolates were obtained (Table 1). Verticillium fungicola (with 50 isolates), Trichoderma harzianum (with 24 isolates), Cladobotryum dendroides (with 16 isolates) and Acremonium crotocinigenum (with 11 isolates) were the most frequent fungi associated with the cultivated mushroom, Agaricus bisporus...

due to high antagonistic activity of trichoderma harizanum, 5 isolates t.h.k, t.h.bi, t.h.mo, var33 and torbat vi were selected and their efficacy was studied for controlling sugar beet damping-off caused by rhizoctonia solani, under in vitro and in vivo conditions.  antagonistic ability of t. harzianum isolates was investigated as dual culture on pda in concomitant and sequential cultures, 48 ...

The antagonistic activities of five biocontrol agents: Trichoderma harzianum, Gliocladium roseum, Bacillus subtilis, Streptomyces noursei and Streptomyces natalensis, were tested in vitro against Colletotrichum acutatum and Colletotrichum gloeosporioides, the causal agents of anthracnose disease in fruit crops. The microbial antagonists inhibited mycelial growth in the dual culture assay and co...

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...

The investigation was carried out at the laboratory of Plant Pathology Department, SASRD, Nagaland University (NU), Medziphema Campus, Nagaland, India during year kharif (August-October, 2020) to evaluate antagonistic potentiality Trichoderma spp. (T. harzianum, T. asperellum and virens) against three diseases pigeonpea viz. Alternaria leaf spot (Alternaria alternata), Collar rot (Sclerotium ro...

to evaluate the effect of metarhizium anisopliae and trichoderma harzianum on root knot nematode (meloidogyne javanica) in tomato, experiments was performed under controlled as well as greenhouse conditions. volatile and non-volatile tests showed that there is no inhibitory effect against every one of each biocontrol agents. on the larval mortality and inhibition of egg hatching, a laboratory t...
