Pot experiment was conducted to find out the competence of some commercial product Trichoderma spp. on management root knot nematode in tomato crop. The RCBD having seven treatments six different including one control three replications. Each treatment had five pots. Twenty days old seedling Shrijana hybrid transplanted and inoculated with 1500 eggs Meloidogyne soil after transplanting seedling...
چکیده : trichoderma spp. به عنوان یکی از عوامل کنترل بیولوژیکی موثر بر علیه دامنه وسیعی از پاتوژنها مانند macrophomina phaseolina (tassi) goid شناخته می شود که از طریق استراتژی های گوناگونی از جمله تولید آنزیمهای تجزیه کننده دیواره سلولی (کیتیناز و گلوکاناز) فعالیت می کند. یکی از عوامل محدود کننده کاربرد جدایه های تریکودرما به عنوان عامل کنترل بیولوژیکی، پایین بودن میزان تاثیر آن در سطح مزرعه ...
The 430 bp ORF of the Aspergillus giganteus antifungal protein (AFP) gene, containing two small introns, was fused between the promoter and the terminator of the Aspergillus nidulans trpC gene. The AFP gene in this vector produced detectable levels of spliced mRNA in Trichoderma viride. In contrast, in the same vector configuration, its 285 bp intronless derivative showed no accumulation of mRN...
Macrophomina phaseolina (Tassi) Goid is a destructive pathogen of cowpea that causes serious charcoal rot disease with significant yield losses. Antifungal activity of three indigenous Ascomycetes viz., Trichoderma harzianum, T. viride, and T. hamatum, and two Meliaceae members, i.e., Melia azedarach L. and Azadirachta indica L. were assessed against the pathogen. Laboratory screening trials wi...
Animals and plants are increasingly threatened by emerging fungal and oomycete diseases. Amongst oomycetes, Saprolegnia species cause population declines in aquatic animals, especially fish and amphibians, resulting in significant perturbation in biodiversity, ecological balance and food security. Due to the prohibition of several chemical control agents, novel sustainable measures are required...
Xylanase is a major enzyme used in the paper and pulp industries for biobleaching applications. There are possibilities for xylanase with better properties suitable for industrial applications. This paper focused on a potential xylanolytic fungus, Trichoderma viride VKF-3, obtained from a mangrove soil sample. Optimum conditions for xylanase production were tested by culturing T. viride VKF3 un...
