The morphological optimization of Trichoderma harzianum was carried out using several surfactants to achieve increased cellulase production. Addition of the surfactants to the culture medium successfully modified the fungal morphology from an aggregated form to a dispersed form. Optimization of the fungal morphology increased cellulase activity up to 177%. The morphologically optimized conditio...

Rhizoctonia solani is a soil-borne pathogen found in soybean plants. The attack can cause the plants to collapse. phase of occurs seedling One control techniques for suppressing fungus be done with preventive measures using biopesticides. This study aims determine spore viability, density, incubation period, disease incidence, severity, and effectiveness after application Trichoderma harzianum ...

The tomato plant is usually infected with various pathogens such as pests, bacteria, and different mycoflora. In this investigation, Tomato cultivar Beeli was pathogenized Fusarium oxysporum f.sp. Lycopersicon (FOL1) fungi. FOL1 fungus controlled by inoculating the plants each one of biocontrol microorganisms, Arbuscular mycorrhiza (AM), Trichoderma harzianum (T. harzianum), microbial blend, na...

The enzymes from Trichoderma species that degrade fungal cell walls have been suggested to play an important role in mycoparasitic action against fungal plant pathogens. The mycoparasite Trichoderma harzianum produces at least two extracellular beta-1,6-glucanases, among other hydrolases, when it is grown on chitin as the sole carbon source. One of these extracellular enzymes was purified to ho...

S: Fusarium solani and Rhizoctonia solani are the common causal pathogens causes the damping off disease of beans (Phaseolus vulgaris L.) in Egypt. The antagonistic effect of four Trichoderma species, i.e. Trichoderma album, Triechoderma hamatum, Trichoderma harzianum and Trichoderma viride, was tested against F. solani and R. solani in vitro, in greenhouse and in field. In vitro tests, all Tri...

Compatibility of the entomopathogenic fungus, Metarhizium anisopliae with representative pesticides, plant oils and a fungal antagonist were studied in vitro. The pesticides tested were: endosulfan, acephate, abamectin, ethion, chlorothalonil, iprodion + carbendazim, thiophanate methyl and dinocap, an antagonist, Trichoderma harzianum and the plant oils: coconut oil, groundnut oil, gingili oil,...
