Abstract Chemical control is still a mainstay for some farmers in shallot center areas such as Brebes, Central Java. Applications of fungicides that are carried out these very intensive and periodically every 3-5 days. The application too can certainly have negative impact on functional microbes including biological disease agents. purpose this study was to evaluate the several brands efficacy ...

abstract in low-input cropping systems, the natural roles of microorganisms in maintaining soil fertility may be more important than conventional system. in order to investigate the effects of plant growth promoting fungi on improvement of growth and development in soybean (cv: jk) an experiment was conducted at the research farm of sari agricultural sciences and natural resources university du...

tomato seedlings were inoculated with t. harzianum bi (106 spores/ml) and salicylic acid (5mm) other separately or combined together in the greenhouse environment. the effect of salicylic acid was investigated on growth of antagonistic agent in vitro. for an investigation of the effect of salicylic acid and of antagonist on pathogenecity factor, treatment with t. harzianum bi by drenching soil ...

Brown spot caused by Bipolaris oryzae is an important rice disease in Southern coast of Caspian Sea, the major rice growing region in Iran. A total of 45 Trichoderma isolates were obtained from rice paddy fields in Golestan and Mazandaran provinces which belonged to Trichoderma harzianum, T. virens and T. atroviride species. Initially, they were screened against B. oryzae by antagonism tests in...

abstract in this study the effect of combination of trichoderma harzianum bi and salicylic acid were studied on root knot nematode (meloidogyne javanica) disease on tomato under green house conditions. the roots of tomato seedlings at six-leaf stage were inoculated with suspensions of fungal antagonist (106 conidia/ ml), 5mm salicylic acid and 2000 second-stage juvenile (j2). combined applicati...

This study aimed to determine the effect of biochar and Trichoderma harzianum toward lead removal in soil, absorption, content plant tissue also growth yield shallot cultivated on lead-contaminated soil. The experimental design used was a completely factorial randomized block consisting 2 factors. first factor corn cobs which applied 1 week after basic fertilizer treatment consisted 4 levels, n...

A simple detached leaf-droplet inoculation bioassay was devised in order to investigate the potential for biological control of Botrytis cinerea by indigenous Trichoderma harzianum isolates. Following preliminary in vitro screening of the antagonistic capacity of four local isolates of Trichoderma harzianum (T1-T4) against B. cinerea, T3 spore suspensions were then tested for their ability to c...

A gene that encodes an extracellular aspartyl protease from Trichoderma harzianum CECT 2413, papA, has been isolated and characterized. Based on several conserved regions of other fungal acid proteases, primers were designed to amplify a probe that was used to isolate the papA gene from a genomic library of T. harzianum. papA was an intronless ORF which encoded a polypeptide of 404 aa, includin...
