TLDR
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.read more

Prospects and limitations for mycorrhizas in biocontrol of root pathogens
TL;DR: The significance of this approach is discussed, and some possible ways of enhancing biocontrol by mycorrhizal fungi are discussed, as currently they can be sold as plant growth promoters without any form of costly registration.

Biological control of plant parasitic nematodes by fungi: A review
Zaki A. Siddiqui,I. Mahmood +1 more
TL;DR: There is an urgent need to develop some easy technologies for formulation and mass production of fungi at a commercial scale for field application and some of these fungi may be used in integrated nematode management programmes despite some obstacles.

Suppression of the biocontrol agent trichoderma harzianum by mycelium of the arbuscular mycorrhizal fungus glomus intraradices in root-free soil
TL;DR: It seemed that growth of and phosphorus uptake by the external mycelium of G. intraradices were not affected by the antagonistic fungus T. harzianum, and the use of a compartmented growth system with root-free soil compartments suggests that nutrient competition is a likely means of interaction.

Improved procedures for clearing roots and staining parasitic and vesicular-arbuscular mycorrhizal fungi for rapid assessment of infection.

TL;DR: To improve stain penetration and clearing in whole mycorrhizal roots of onion and other host plants, and in roots infected by other fungi, the following two procedures are developed, which give deeply stained fungal structures which show distinctly against the outlines of the cells in the cortex of intact roots.

TL;DR: The standard error of four methods of assessment based on observations of stained root samples either randomly arranged in a petri dish or mounted on microscope slides are calculated.
