Trichoderma suppress fusarium and it work good if it seed, soil treated with trichoderma and even, every 28 days interval trichoderma should apply to the soil..

Different species and strains of Trichoderma can inhibit Fusarium diseases such as vascular wilts and root rots. There are commercial products available for this purpose. As Md. Rakibussarman suggests seed and seedling treatments can be useful and optimization of the control may require repeated applications. The Trichoderma fungi act as competitors and as hyperparasites can can be stimulators of the biochemical mechanisms which foster systemic acquired resistance.

Yes.Different species of Trichoderma can inhibit Fusarium diseases in crops. Among them i found that Trichoderma viride (1%) concentration is most effective in controlling Fusarium wilt of Arachis hypogaea L. Next i have good results with Trichoderma harzianum (1.5%) concentration.

It is effective strain isolate locally

Yes, Some species of Trichoderma may control pathogenic Fusarium in wheat

Yes I found significant effect on Fusarium oxysporum f lycopersici on tomato by Trichoderma harzianum. Vermicompost also improves the effect of Trichoderma. You can see my work on researchgate

When working with inoculants one of the greatest principles is that their effectivity will vary mostly related to there anti and pro biosis capacity but also related to their capacity to associate with the plants as endophytes and to maintain themselves in an antagonistic soil environment.

The ability to determine comparative anti and pro biosis can be fostered by targeted bio assays and the the use of a mixture of active isolates can help ensure an ability for the treatment to sustain itself in variable antagonistic soil environments.

Rhizbobium inoculants typically nave 6 to 15 strains.

It depends on the species that you intend to use as biocontrol.

Biological control by Trichoderma species of Fusarium solani causing peanut brown root rot under field conditions

Abstract

Fusarium solani is one of the most important pathogens causing brown root rot in peanuts in Argentina. Under conductive conditions like drought stress, the losses could reach 95% of production in some fields. Fungicide treatments are not effective enough to control the disease. The objective of this study was to evaluate Trichoderma species as potential biocontrol agents to reduce the impact of the disease. Under greenhouse assay the optimum inoculum concentration of Trichoderma harzianum ITEM 3636 and T. longibrachiatumITEM 3635 were selected for field trials. Both species were evaluated in a field trial performed in 2003/04, in a commercial field with a previous history of the disease. Two seed treatments were evaluated: seeds coated with a conidial suspension using carboxymethylcellulose (CMC) as sticker and seeds coated with the antagonist fungal biomass on Biodac particles. T. harzianum in both seed treatments was more effective than T. longibrachiatum in decreasing the mean disease severity index (MSI), increasing the frequency of healthy plants, and boosting yield. During the 2004/2005 growing season the potential of using this strain to control the disease and the plant growth promoter effect was confirmed in three experiments carried out in fields artificially and naturally infested with the pathogen.

Dear. attachment may be useful to you.

Best Regard

Trichoderma strains are effective in the control of Fusarium diseases like Fusarium wilt and Fusarium rot in various crops. Presently i found that Trichoderma viride in combination with Pseudomonas fluorescens is very effective in the inhibition of Fusarium oxysporum causing Fusarium wilt in Arachis hypogaea.L . Earlier when i am working with single species of Trichoderma, i found the best results with Trichoderma viride. you can see my work on Research gate.

yes, Trichoderma may control pathogenic Fusarium

Yes differnt species of Trichoderma inhbtion fusarium in vivo and invtro

While Trichoderma can be generally effective against a wide range of pathogens the best result will occur with strains which are root and soil competent or able to survive and thrive and the triple fact is showing positive plant physiological reactions. In this regard strain T22 would be prepared the best single selection in Trichoderma harzianum species complex. Many Trichoderma are very able to thrive with certain fungicides and integrated control would be a possibility. In addition the use of composts in addition to these strains are very useful. The compatibility and efficacy and adaptability are best determined by local studies to determine their effects.

Yes, Trichoderma spp may control pathogenic Fusarium spp

Yes, It can manage but strian should locally isolated otherwise not effective suppressed Disease

In fact, Trichoderma species are a very good biological control agent against oomycetes (Phytophthora spp. and Pythium spp.) and to a lesser degree against Dutromycetes fungi, especially Fusarium.

Trichoderma can be isolated from crop plants of interest isolated strains can be tested for the quality of interest isolated strains which growth promoting should also have capacity persistent in the soil

There are multiple strategies which Trichoderma biocontrol can be beneficial. It can be mycoparasite whish is active again the common soil root complex of Pythium, Fusarium and Rhizoctonia. But the mechanism is also growth promotion related to the ability of Trichoderma to promote auxins which stimulate growth and also organic acids and chelators which mobilize immobile soil nutrients such as Phosphorus which is insoluble. There is the ability to stimulate plant resistant mechanism which improve the ability of plants to address various stresses. Not only is Trichoderma natural but for most applications it is generally recognized as safe. Trichoderma is associated with lignocellulosic plant wastes and it is demonstrated pathogen for mushroom production. Otherwise it offers great opportunities for issues which are common and limiting but it does require adaptive work to identify its utility in specific situation. Trichoderma are easily isolated from soil purified in culture and tested in the laboratory and greenhouse.

I agree with Pilli Rajeswari and Paul Reed Hepperly.
