There are two main types of mycorrhizae, usually referred to as Endo and Ecto. The majority of garden plants and vegetables are “Endomycorrhizal”. The main exceptions are some hard woods, oak trees for example, which are “Ectomychorrizal” and brassicas which are non mycorrhizal.
The different TNC Mycorr products contain either a variety of endo-mychorrhizae or a variety of both endo and ecto-mycorrhizae. The short answer to the question “Which is best?” is that there isn’t a best – as long as the product contains whatever your plants need.
The other differences between the TNC Mycorr products are with the additives and supplements that they contain.
As its name implies this is a mycorrhizae containing purely endo species (9 sp.) It is suitable for most garden plants and vegetables with the exception of certain hard-woods and all brassicas. This is the least expensive of the Mycorr range but is fine for most applications.

TNC MycorrMulti contains 9 endo species of mycorrhizae and 6 species of ecto mycorrhizae. With the exception of brassicas and erricaceous plants, it can be used for practically all other plants, trees and shrubs including hard-woods.
This product also contains humate and seaweed which act as a stimulant within the rhizosphere (and soil food web) to ensure the plant is given a good start. TNC MycorrMulti is a slightly more expensive than MycorrMulti but considering that it is “multi-purpose” it is a good buy.

This is an endo mycorrhizae containing 9 different species and although it was originally designed for use with roses, it can be used with most other plants. The main thing about MycorrRose is that, although it is a relatively inexpensive product and like MycorrMulti contains seaweed derivatives and humate, it also contains beneficial bacteria.
When planting roses – which are not exactly cheap plants it is not a bad idea to take out a bit of insurance and ensure that the plant is colonised with beneficial species of fungi and bacteria before the less desirable species find their way in!
The bacteria in MycorrRose also include phosphorous solubilizing bacteria which can “unlock” phosphorous from otherwise insoluble sources, bone meal, rock phosphate and calcium phosphate. Phosphorous plays an important role in the development of plant roots. It is with this combination that we believe will give you the edge when combating ‘Rose Replant Disease’.

A product for exhibition and specialist growers. As well as endo and ecto mycorrhizae, humate, seaweed derivatives and beneficial bacteria, MycorrMax also contains 5 species of Trichoderma.
Trichoderma are a type of fungi useful for combating pathogenic species such as Botritus (Grey mould), Fusarium and Pythium (Root rot), they will also stimulate a plants natural immune system.

This is primarily designed to be used in solution and for hydroponics applications, flood and drain or aeroponics for example. It is also ideal for hand watering or injecting in to the rootzone of established plants.
MycorrHydro has a much higher concentration of mycorrhizae than the other TNC products. It contains 15 different mycorrhizal fungi species and as these will be distributed throughout the hydroponic reservoir there are many more of them.
In addition to the mycorrhizae MycorrHydro contains 5 Trichoderma species along with 13 different bacillus (beneficial bacteria) species.
Finally MycorrHydro contains bio-stimulants such as humic acid and derivatives of a marine algae (Ascophyllum nodosum). These include amino-acids, plant hormones – cytokinins, auxins and giberellins – as well as vitamins and trace elements.
