The most complete mycorrhizal fungi available.

SKU: MycoGold Categories: , ,


Most mycorrhiza products sold today only contain endomycorrhiza which limits the spectrum of crops mycorrhiza can be used. MycoGold is a complete balanced mycorrhiza blend including endomycorrhiza, ectomycorrhiza, trichoderma and beneficial bacteria to increase plant compatibility and boost production. Most soils in Australia have had their mycorrhizal population destroyed via over use of pesticides, fallow land, crop rotation and soil degradation. The loss of these mycorrhizal populations has increased the crops reliance on expensive inputs like fertiliser/pesticides and water. Replacing the mycorrhizal fungi can make the crop is less reliant on expensive inputs and still achieve maximum production.

When to Apply and Re-Application:

MycoGold is a good option all year round so apply as soon as you receive the product. MycoGold is a living microbial product so if the host plants are healthy and soil conditions are good (pH close to neutral, low chemical use, adequate soil moisture) MycoGold will naturally multiply without any further inputs. If conditions are adverse, re-application is required. I personally like to re-boost microbe numbers at the beginning of each growing season which is normally in Spring each year.

Frequently Asked Questions (F.A.Q)

How do mycorrhizal fungi work?
Mycorrhizal Fungi form symbiotic relationships with the roots of plants. They provide them with soil nutrients/water that would otherwise be inaccessible. These fungi not only grow within the roots of plants, but also form an intricate network around the roots and soils where it looks for nutrients. Plants provide the fungi simple sugars they produce through photosynthesis in exchange for their service. On top of this they can for a mycorrhizal network that allows plants to communicate about potential threats!

What are mycorrhizal fungi?
Mycorrhizal fungi are a non-monophyletic group (they have distinct genetic lineages) of fungi that form symbiotic associations with the roots of plants.

Why are mycorrhizae important?
Mycorrhizal fungi have allowed plants to dominate the terrestrial world by allowing plants to grow in soils that would otherwise be inhospitable. They are not only crucial to wild ecosystems but also agriculture and forestry.

What do mycorrhizal fungi do?
Mycorrhizal fungi provide many beneficial services to the plants they associate with but are best known for their ability to provide plants with mineral nutrients from soils, particularly phosphorus.

Which plants benefit from mycorrhizal fungi?
Plants that are growing in less than optimal conditions and in soils that may be limited in some nutrients. Most plants can form these associations but only will when absolutely needed. Almost all types of plants form these associations, excluding the mustard family.

How to use mycorrhizal fungi?
To apply mycorrhizal fungi you typically apply an inoculant made of spores into the soil or near the roots of plants.

What is a Mycorrhizal Inoculant?
A Mycorrhizal Inoculant is material which contains dormant spores of mycorrhizal fungi that can be introduced to plants to induce symbiosis. Once the spores are hydrated and no longer in dormancy they start to associate with plant roots within 24-36 hours.

How to use mycorrhizal inoculant?
When planting from seed you can apply a small sprinkle directly into where you are placing seeds. When transplanting apply the inoculant near the roots of your transplant. Alternatively you can slightly mix it with the top soil near the roots of established plants.

Can you use mycorrhizal fungi after planting?
It is best to apply directly near the seed or root zone of plants, but it can be applied as a top dressing and gently mixed/watered in.

Can you use too much mycorrhizae?
No, but it is not cost effective to use an excessive quantity.

How do you inoculate soil with mycorrhizae?
You can use fresh soil from a healthy pasture but that has added problems as undesirable microbes (pathogens) could be added so best to use a clean inoculmn.

Does tap water kill mycorrhizae?
Chlorine or Chloramine in tap water may harm and inhibit mycorrhizae but will not severely affect established mycorrhizal fungi. Have an aerator on your tap to the chlorine can escape.

Does fertilizer kill mycorrhizae?
Some synthetic fertilizers damage mycorrhizal fungi and inhibit their growth. Well nourished plants in well fertilized soils are less inclined to form mycorrhizal relationships. Compost and other natural amendments should not interfere with mycorrhizal fungi.

How long does mycorrhizae take to work?
In just a couple of days you can begin seeing improvements in growth and health of plants!

How do you feed mycorrhizae?
There is no need to! Plants feed them through sugars produced by photosynthesis.

Can you top dress mycorrhizae?
It is best to slightly mix mycorrhizal inoculants in to the top soil to protect it from environmental stresses and place it near the root zone.

What do mycorrhizal fungi eat?
Mycorrhizal fungi mostly consume simple sugars produced by plants that they receive in exchange for nutrients they extract from soil.

What are the two types of mycorrhizae?
The two most common are Arbuscular Mycorrhizae and Ectomycorrhizae. Arbuscular Mycorrhizae are the most common and associated with 95% of plant species including most crops of agricultural value. Arbuscular Mycorrhizae do not form mushroom fruiting bodies and are also sometimes referred to as “endomycorrhizae”. Ectomycorrhizae are associated with widely dispersed and long lived perennial trees like Oak, Pine, and other Conifers. There are several other types of mycorrhizal fungi but they are less common and associate with select groups of plants.

What are Endomycorrhizal Fungi?
Endomycorrhizal Fungi form mycorrhizal structures inside the root cells of plants. There are different types of Endomycorrhizal fungi but the most widespread are Arbuscular Mycorrhizal fungi (AM fungi) that belong to the genus Glomus. These fungi do not form the mushroom fruiting bodies but solely produce soil borne spores. AM fungi associate with about 95% of plant species and are the most relevant in agricultural contexts.

What are Ectomycorrhizal Fungi?
Ectomycorrhizal Fungi (EM Fungi) are fungi who do not form mycorrhizal structures within the root cells but grow profusely between the root cells. They contain 3 main components: a hyphal matrix that surrounds the cells, a sheath that surrounds the root bark, and hyphae that extends out into the soil. These fungi produce mushroom fruiting bodies including many prized edible species. EM Fungi associate with Oak, Pine and other dominant forest species which only encompass around 4% of all plant diversity. They do not associate with conventional crops.

What are the benefits of mycorrhizae?
They allow plants to live in otherwise inhospitable soils by providing them with access to soil nutrients and water. This increases productivity and final yield without the need for extra inputs in an agricultural context. .

Can mycorrhizae be harmful to plants?
No. While some studies suggest minor pathogenic behavior in laboratory conditions, this is rare and not observed in field studies.

Does fungicide kill mycorrhizae?
Yes it can. Fungicide can inhibit growth and even deplete the soil of mycorrhizal fungi. Only use fungicides if it makes sense. If applying fungicide wait 4 weeks until applying MycoGold.

What is a Mycorrhizal Network?
The Mycorrhizal Network connects plants of the same or different species through fungal mycelium. This allows plants to exchange nutrients and alert each other of environmental threats.

Is Mycorrhizae a Fertilizer?
Mycorrhizae does not directly improve your soil fertility or contain plant nutrients.

Are Mycorrhizae Mushrooms?
No. They are a fungi, most of which do not actually produce mushroom fruiting bodies! Mushrooms are actually only the reproductive structure produced by specific groups of fungi.

Do Mycorrhizal Fungi live without Plants?
Mycorrhizal Fungi cannot grow and complete their life cycle without associating with plants.

Is mycorrhizal fungi compatible with legume rhizobium bacteria?
Yes there isn’t a issue as they both do different functions for the plant. Follow the application rates for each.

How do you pronounce Mycorrhizae?
It is pronounced: mai·koh·rai·zee or Mike·O·Ri·Zee

How do you pronounce Mycorrhizal?
It is pronounced:  mai·koh·rai·zal or Mike·O·Ri·Zal

    I am keen home gardener in Brisbane. This zucchini grew from flower in only 8 days while I was on holiday over Christmas. The plant has been in over 9 months, and I added Mycogold at seedling transplant time. The sweetcorn in the background is the best I’ve ever grown. I added Mycogold as I planted into a well-composted bed.

  22. Jeff Major (verified owner)

    Exceptional improvement in plant growth, tolerance and production, with less overall water requirement – all as expected when the micro rhizome is functioning better. For the first time in 17 years I can get tomatoes and zucchini to produce, but unfortunately Myco Gold does not stop the rats eating the tomatoes….

    Although its difficult to assess the difference MycoGold has made to our Australian native garden, I know from my agronomy background that micorrhizas are vital to Australian natives and despite a difficult soil here the plants and shrubs are growing nicely. I think that stability and reliability of growth is the main effect I think I can see.

    I am extremely happy with both the product as well as the prompt and efficient customer service.

    I became interested in mycorrhizal fungi when I was studying my Diploma of Horticulture. I reached out to Tim for advice as I was daunted by the task of developing a horticulture related science experiment for one of my major assignments. Tim was very helpful and encouraging, answering my questions and guiding me on my way. As I am a keen backyard gardener, I decided to design a controlled experiment to test what effect mycorrhizal fungi had on the growth of tomato seedlings. I grew over 100 seedlings, using various methods to monitor and record data about their growth/health over a 6 week period. Although it was a fairly basic backyard experiment (I am only an amateur scientist!), there was no doubt that the seedlings which had been inoculated with MycoGold performed much better. They grew with more vigor, and when measuring and weighing the root mass of each individual plant (at the end) the differences were remarkable. I have continued to use MycoGold in my gardening ever since, and encourage others to do so to. I am on the committee of a local organic gardening group, and many of my fellow members have also used it and been very impressed. Thanks!


  34. Claire B. (verified owner)

    Very happy with the mycogold, would definitely recommend. Our vegetable seedlings were much faster to establish than usual, and they have stood up much better to the recent hot weather. We also used it on our fruit trees (young saplings and older established plants). All of them put on lots of new growth after applying the mycogold, and the younger trees in particular look really strong and healthy.

    I read that this product would prevent replanting disease in roses. This was certainly the case.
    I used the rest of the pack to treat all my existing roses before adding a thick dressing of manure rich compost.
    The response was very gratifying.

    My roses have never looked better. They say do not grow roses in the same place as one have died, but having drenched the ground with Mycogold before planting the next one it has never looked back. Would thoroughly recommend using this product.


  43. Chris (verified owner)

    Great product, huge increase in root growth and quality, makes for plants being able to uptake more water and nutrients thus grow faster, healthier and bigger
