TL;DR: Data presented throughout this article suggest the high value of T. harzianum as a source of genes able to facilitate the achievement of producing plants resistant to abiotic stresses without alteration of their phenotype.

TL;DR: In this paper, the effect of Trichoderma harzianum on the corrosion of AZ31 B magnesium alloy in artificial seawater (AS) has been studied, and the results showed that the presence of T. harzmanianum decreased the pH and E corr vs. SCE.

TL;DR: Five microbial plant growth promoters or biocontrol agents were assessed for ability to proliferate on seeds of carrot, parsnip and leek and Comparisons were made between proliferation and survival in large-scale drum priming with post-priming application of microorganisms.
Abstract: Five microbial plant growth promoters or biocontrol agents (Pseudomonas fluorescens CHA0, Pseudomonas sp. AB842, Bacillus subtilis MBI600, Trichoderma harzianum T22 and T. virens G20) were assessed for ability to proliferate on seeds of carrot, parsnip and leek. In small-scale priming systems, both pseudomonads and MBI600 (when applied as cells) at levels between 105 and 106 cfu g−1 seed were able to colonise all seeds at the end of priming (240 h) despite initial poor recovery after addition of the cells in some cases. Pf CHA0 was a particularly aggressive seed coloniser often comprising the total pseudomonad population at the end of priming. Drying the seed after priming resulted in <1 log10 cfu g−1 seed loss for the pseudomonads but greater losses for MBI600 on carrot and leek seed. Application of spores of MBI600 resulted in little loss in cfu g−1 seed following addition of the cells and these levels were maintained throughout the priming period and after drying back. Both T22 and G20 were recovere...

TL;DR: Simultaneous use of biocontrol agents against pathogens gave better control than their individual application in management of wilt disease complex of pigeonpea caused by the nematode Heterodera cajani and the fungus Fusarium udum.
Abstract: Glomus mosseae, Trichoderma harzianum, and Verticillium chlamydosporium were used alone and in combination for the management of wilt disease complex of pigeonpea caused by the nematode Heterodera cajani and the fungus Fusarium udum. Treatment of plants inoculated with pathogens increased plant length, shoot dry weight, number of nodules, and reduced nematode multiplication and wilting index. Simultaneous use of biocontrol agents against pathogens gave better control than their individual application. T. harzianum had an adverse effect on root colonizaiton by G. mosseae. Parasitism of nematodes by V. chlamydosporium was also reduced in the presence of T. harzianum. The highest reduction in nematode multiplication was observed when all three biocontrol agents were used together.
