The majority of crop plants, grasses, indigenous trees and shrubs in South
Africa are associated with arbuscular mycorrhizal (AM) fungi. A few non-mycorrhizal
plants include cabbages, sugar beet, beetroot and proteas. Other types of
mycorrhizal fungi associate with other plant families. Check the mycorrhizal
status of your crop or plant of interest, ASK A SCIENTIST.
The Mycoroot product in a granular formulation, which contains specially,
selected strains of indigenous southern African AM fungal types. Extensive
research has been conducted at South African universities by qualified experts
in the field to demonstrate the effects of Mycoroot on plant growth. Examples of
these are presented below:
Key:
Myc Inoculated
Myc Control
(MYC+; treated with
Mycoroot)
(MYC-; not treated with Mycoroot)
| Chicory: |
|
 ....
 |
 |
|
|
|
MYC + chicory roots at harvest showed a
57% increase in fresh root weight and a 59% increase in dry root weight
compared to MYC- chicory.
|
 |
 |
|
|
|
Soybean: |
|
|
MYC – soybean plants affected by herbicide residue in soil (foreground)
and MYC + plants growing well in the same soil (background). Mycoroot is
compatible with the use of nitrogen fixing bacterial inoculants,
enhancing the bacterial ability to bind nitrogen.
 |
| |
|
| Beans: |
|
|
MYC + beans on left and MYC – plants on right, showing effects of
nitrogen deficiency. Mycoroot is compatible with the use of nitrogen
fixing bacterial inoculants, enhancing the bacterial ability to bind
nitrogen.
 |
|
| Tomato:
|
|
|
Tomatoes grown in low phosphorus soils,
MYC + (left) are unaffected while MYC – (right) showed poor growth. |
|
 .... |
 |
|
Low
Phosphorus content soils |
|
The
effect of drought stress on tomato seedlings, MYC + (left) survival
after 28 days without water, MYC – (right) severely affected and beyond
recovery. |

|
|
MYC + seedlings (left) showing increased plant growth compared to MYC –
(right) seedlings.
 |
|
| Honeybush: |
|
|
 ....
|
|
|
Honeybush plant growth increased with MYC + (left) compared to MYC –
plants in the field. Graphs show increase in photosynthetic activity as
measured by performance index (left) and increased plant height (right). |
| |
|
 |
 |
|
| Maize: |
|
|
Leaf rust and gray mould infection of MYC – plants covering 70% of leaf
surface, while MYC + plants had little signs of infections, less than
5%. |
|
 .... |
 |
|
Cob weight of MYC+ plants (left) increased
by 19% compared with MYC- (right) |
|

Rehabilitation: |
|
|
|
|
|
Revegetation of coal mine tailings showing increased grass germination
in MYC + plots (left) compared with poor germination in MYC – plots
(right).

|
| Indiginous Trees:Rhus
(Karee boom) |
|
|
Two indigenous Rhus trees
(left) with MYC + showing increased growth compared to MYC – tree
(right), which was also covered with insects. |
