The Benefits of Beneficial Organisms - Guineapig and IM Boggled, CC forums circa 3-2006

The effects of micro-organisms on a plant can be profound. These organisms, such as bacillus, mycorrhizae and trichoderma all form symbiotic relationships with the plant and are found in soil. Bacillus is used world wide for the control of loopers, fungus gnats, insect pests and opportunistic fungi pathogens. Tricoderma is a fungi that feeds off pathogenic root rot and damping off fungi; it also stimulates the plants root and immune systems, which helps the plant to fight off fungi attacks. Mycorrhizae is a beneficial fungi which colonizes the root surface; this helps keep the pathogenic fungi from getting a foot hold on the plant’s root system. Mycorrhizae also helps the plant take up nutrients that are out of reach of the plant’s roots. All of these beneficial organisms feed off plant exudes from the root system and some nutrients in the growing medium.

How to use beneficals in your system.

To get the maximum benefit from beneficial micro-organisms, the gardener should always provide food for these beneficals. Providing these organisms with food (e.g.: Liquid Karma, Earth Juice Catalyst and Sweet) ensures that they will grow and multiply in your garden, however, the harmful micro-organisms will also use this food to multiply. This is one of the reasons why your water and growing medium should be well oxygenated. Harmful pathogens tend to thrive in anaerobic conditions whereas beneficial organisms thrive in aerobic conditions.
For clones and seedlings – Use both Hydroguard (15ml per gallon) and Rhizotonic (15ml per gallon). These two products can be used in clone machines, rockwool cubes and Rapid Rooters. The Hydroguard contains two bacillus strains which secrete anti-biotics which will fight off root rot and damping-off pathogens. The Rhizotonic will help your young plants develop vigorous, healthy, strong roots; it will also provide the bacillus with some food. If your seedlings or clones develop a stem rot Hydroguard can be painted on the affected area (1 part Hydroguard 3 parts water).

For plants in soil – Most gardeners who grow in soil will use organic nutrients to feed there plants. Mycorrhizae suits plants that are being fed organic nutrients; chemical nutrients, especially when the concentration builds up in the growing medium, will destroy the Mycorrhizae. It is best to apply Mycorrhizae into the soil before planting (1 teaspoon of Rooters Mycorrhizae per gallon of soil). Bacillus and tricoderma can also be used on plants grown in soil. One pouch of Subculture should be mixed into 8 cubic feet of soil. A maintenance application should be reapplied every 4-6 weeks at 1 teaspoon per 10 gallons of water. A weekly application of Liquid Karma or Earth Juice Catalyst will help keep your plants healthy and also provide the beneficial organisms with essential foods to keep them multiplying. This program can also be used for plants being grown in coco fiber that are fed organic nutrients.

For hydroponic systems – Mycorrhizae does not do well in hydroponic systems as it is sensitive to the nutrients that are used for hydroponics. For hydroponic systems it is best to use Subculture or Hydroguard. Both these products contain bacillus strains which are well suited to hydroponics even in systems that have high salt contents. Subculture should be applied at a rate of 1 teaspoon per 10 gallons of water/nutrient solution (1 pouch per 50 gallons). The first application of Hydroguard should be 15ml per gallon and maintenance applications at 5-10ml per gallon of nutrient solution. For coco fiber, rockwool and Ready-Gro mediums, both Hydroguard and Subculture should be reapplied 21 days after first application and thereafter every 21 days. For hydroponic systems that use Hydroton rocks, perlite, NFT or aeroponics, the Subculture and Hydroguard should be reapplied every 7 days.

Foliar Sprays – Both Hydroguard and Subculture can be used as a foliar spray to help control mildew that attack the leaves, stems, flowers and fruits of plants. Serenade is another product which contains only Bacillus subtilus. These bacteria will effectively control most leaf fungi pathogens.

Fungus Gnats – Bacillus thuringienses sub-species israelensis (the active ingredient in Gnatrol) is used for the control of fungus gnats. This bacteria produces a parasporal crystal which is toxic to the larvae of fungus gnats.

Please note: Even though you are dealing with a biological organism, always wash your hands with an anti-bacterial soap when finished, and when using these products as a foliar spray use a mask. Keep these products away from children and animals.

The term mycorrhizal comes from the Latin words myco, meaning fungus, and rhiza, meaning root. Mycorrhizal fungi are fungi that have developed a symbiotic (mutually beneficial) relationship with the root systems of living plants, from garden vegetables all the way up to Old Growth trees. Networks of mycorrhizal filaments envelop the seedling's root structure, greatly extending and enhancing (by a factor of several hundred to several thousand times) the growing plant's water- and nutrient-gathering abilities and protecting the plant from disease.

This is a good and Inexpensive innoculation product :)

Plant Success Mycorrhizae Tablets
A mixture of 12 species of endo- and ectomycorrhizal fungi, Plant Revolutionâ„¢ Plant Successâ„¢ Tabs are designed to help the gardener or home landscaper promote fast plant and root growth, increase nutrient and water uptake and reduce fertilizer use. Each Plant Successâ„¢ Tab consists of millions of spores of the following mycorrhizal species:

Glomus mosseae
Glomus intraradices
Glomus clarum
Glomus monosporus
Glomus deserticola
Glomus brasilianum
Gigaspora margarita

Pisolithus tinctorus
Four species of

Exceptionally helpful for those who use commercial potting soils, which are sterilized and therefore devoid of beneficial microorganisms.

Fungi Perfecti, a legal edible mushroom growers supply company, is the apparent manufacturer of "plant success"

GrowStuffPlus! stocks it as do others if one googles it.

"DIEHARD BioRush":
is a dry, water soluble root growth stimulant with nitrogen fixing, phosphorus solubilizing and growth promoting beneficial bacteria packaged in pre-measured, labeled bags for easy use with tank sprayers. Contains humic acid extracts, Trichoderma, soluble sea kelp, yucca plant extracts, amino acids and natural sugars to “energize” the microbial activity in the ground and promote cell division and lateral bud development as well as delay the aging process of plant tissue. Our unique formulation of ingredients affect the permeability of cell wall membranes in roots, improve plant respiration, photosynthesis, promote cell division and lateral bud development as well as delay the aging process of plant tissue. All these factors are well known to provide major benefit to plants promoting vigorous root growth and the overall general condition of the plant environment.
The 1/4 lb. bag makes 25 very "hot" gallons.
Its best to mix/brew/stand seperately and then add splashes to nutrient mixes to innoculate, imho, using this product.
I've used it on various trees and gardens with a wide variety of fruits and vegetables in them and it tends to make a very noticeable difference compared to other gardens not beneficially innoculated.

I plan on growing some giant watermelons in the ground next year to compete in the county fair with, and this DieHard stuff will be one of my secret weapons (along with Guano's).
I have some Carolina Cross watermelon seeds from a 268.8 pounds, 37" long, 49" blossom to stem, 62.5" circumfrence specimen. (In metric lets just call that 122 kilogram, meter long mother "massive".)

Those Heirloom Tomato guys better hang onto there hats 'cause I'm coming to take their Blue Ribbons home too.

Informative post G.P., Thanks for sharing. :)

--Guineapig comes back

you know we are getting somewhere with IC when i have to go back and use myself as a reference.....way to go IC info gurus!!!

Components Used In DIEHARDâ„¢
Mycorrhizal "Cocktails"
I. Mycorrhizae - An estimated 10,000 research studies have been done on mycorrhizae during the past 25
years. Mycorrhizal fungi inoculants have been available to commercial markets only during the past 5
A. Endomycorrhizae - A symbiotic relationship of endomycorrhizal fungi with roots of 90% of plant
species worldwide.
1. Inoculant contains multi strains of live spores of Glomus mosseae, Glomus intraradices,
Glomus fasciculatum, Glomus dussii, Glomus clarum, Glomus deserticola and Glomus microaggregatum.
2. Available in dry form with a shelf live of 18 months.
B. Ectomycorrhizae – A symbiotic relationship of ectomycorrhizal fungi with many tree species i.e.
pines, oaks and select hardwoods.
1. Inoculant contains multi strains of Pisolithus tinctorius and a variety of species of Rhizopogon.
II. Trichoderma and other beneficial fungi- Trichoderma (6 species), Gliocladium virens (2 strains), Trichoderma
harzianum (2 strains), Trichoderma viride (2 strains).
Trichoderma is a recognized beneficial fungus that is used to compete with the food source and space of
negative causing fungi in the soil. Spores of the fungus, when mixed with soils, germinate and grow around
plant roots depriving negative fungi the living space and food source thereby causing death to them, therefore
preventing fungal diseases.

Bacillus azotofixans (2 strains): nitrogen fixation
Bacillus azotoformans (3 strains): nitrogen fixation, plant growth hormones
Bacillus megaterium (2 strains): decomposition, nutrient cycling
Bacillus polymyza (5 strains): anti-fungal, nitrogen fixation, nutrient cycling
Bacillus thuringiensis (2 strains): entomopathogenic
Bacillus licheniformis (6 strains): enzymes, plant growth hormones, soil structure
Bacillus pumulis (2 strains): decomposition, nutrient cycling
Bacillus subtilla (10 strains): anti-fungal
Psuedomonas aureofaceans (2 strains): anti-fungal
Streptomyces lydicus (2 strains): anti-fungal
Trichoderma harzianum (2 strains): anti-fungal, plant growth hormones
Trichoderma viride (2 strains): anti-fungal, plant growth hormones
Gliocladium virens (2 strains): anti-fungal

here is an addendum to today's lecture. below you will find a description of the different types of endomycorrhizae species...

Characteristics of Endo Species Used:
Glomus dussii
Adapted to a large range of pH from 4,5 to 7, and is efficient on plant growth, and
preferably on tropical plants.
Glomus intraradices
Very common throughout the world. Shows disease resistance mechanisms against
Fusarium oxysporum.
Glomus fasciculatum
Adapted for drought conditions in high phosphorus soil. Also very effective in high
salinity conditions and is efficient on plant protection again some pathogenic fungi within
Glomus deserticola
Adapted for drought conditions, and has shown good agronomical effect under low soil
Glomus microaggregatum
Adapted for drought conditions, and can have agronomical effect under low soil fertility.
Glomus clarum
Adapted to acidic pH 5-6, this specie is highly proliferous and can produce large quantity
of external mycelium in the soil and can occupy the rhizosphere.
Glomus mosseae
Adapted to acidic pH 6-8.5, this specie is highly proliferous and can produce large
quantity of external mycelium in the soil and can occupy the rhizosphere.

Sporulation Characteristics of Endo Species Used:
Some strains such as Glomus deserticola, Glomus microaggregatum, Glomus mosseae,
and sometime Glomus intraradices produce clusters of spores very (like a "popcorn ball").
Most of time, Glomus deserticola and Glomus microaggregatum produce clusters with as
many as 500 spores minimum stuck together.
Glomus mosseae produce external sporocarps (5-10 spores inside) or
external clusters of "young spores" and Glomus dussii produce external sporocarps
(containing hundred of very small spores) and also external spores entrapped within the
external mycelium.
Glomus intraradices produce large quantity of INTERNAL spores inside the root
(hundred spores /cm of root can be counted sometime).
All these "natural occurring” sporulation configurations must be considered for the
counting of spores.
Endomycorrhizaes are not Ecto. and this difference must be
The most important aspect is the standardization of the product and
the efficiency and quality.
