root-knot nematodes (meloidogyne spp.) are among the most important groups of plant-parasitic nematodes, causing damage and yield losses to most cultivated plants. the bacterium pseudomonas fluorescens cha0 and the fungus trichoderma harzianum bi were investigated for biological control capability and systemic induction of resistance against the nematode m. javanica under glasshouse conditions....

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...

The use of fungi the genus Trichoderma spp. for control plant diseases it has proved to be an important and promising tool, mainly tomato crop production system, however, there are difficulties in establishing bioagent. This work aimed evaluate effect substrate incubation time after inoculation with harzianum damping-off seedlings. experimental design was completely randomized, consisting six t...

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...

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 ...
