Bio Treat Digester is a non-pathogenic saprophyte that colonizes soil, water and plant surface environments and improves root development and the general biology of the plant and soils.

Containing 2 x 108 cfu/ml of microbe, Bio Treat Digester helps suppress plant disease by entering the plants vascular system and acting as a systemic bio-control agent against a range of bacterial and fungal diseases.  It does this by producing a number of secondary matabolites including siderophones, antibiotics and natural hydrogen cyanide.

Because Bio Treat Digester rapidly colonizes the rhizosphere it competitively excludes pathogens which may also be an important factor in disease control and improved plant health.

The key biology of Bio Treat Digester has been trialled around the world more than any other biological agents. Crops include Lucerne, Pasture, Maize, Clover, Cereal crops, Cucumber, Eggplant, Tomato, Potato, Flowers & ornamentals, Grapes, Fruit and many more.

Substance: Natural fungal biology 2 x 108 cfu/ml


Prior to use read all instructions on the label.

Bio Treat Digester is a fantastic biological product for complementing, enhancing and boosting the soil’s own natural biology to improve root development and for plant diseases.

There is no withholding period.

For optimal results use in conjunction with
Bio Treat N and Bio Treat Humate. 

Bio Treat Digester Is not a foliar spray so it is best to apply either directly to the soil or onto recently grazed grass.  To ensure the best performance soil conditions such as temperature, pH and organic matter levels are important. 

While Bio Treat Digester can be applied early the soil temperature needs to be at least 8o C minimum as the bacteria will only activate at optimal soil temperatures.  Soil pH can be as low as 5.7 but ideally should be in the range pH 6.0 – 6.5.

  • Apply to short grass or soil as not intended as a foliar spray.
  • Best applied early morning or late afternoon.
  • Optimal results achieved when used as part of a complete biological package including
    Bio Treat N and Bio Treat Humate.
  • Shake the bottle well to ensure the response of the biology.
  • Ensure that once opened the lid is reapplied firmly and even then it should be used within 3 months.
  • If adding the natural Bio Treat Humate and BioTreat N then add to the mix last and use within an hour.
  • Do not mix with any chemicals, herbicides, fungicides or soil fumigants as these can kill the live biology in Bio Treat Digester.


Refer to directions on the label.  Caution must be used with any sprayed products and live biological products are no different.

Store in a dry, cool place away from direct sunlight.  Keep the temperature under 20oC at all times and if you are able to refrigerate then this is ideal.  However, DO NOT FREEZE and in colder parts of the country keep at or above 4oC.

If you are undergoing chemotherapy or your immune system is compromised in any way you should avoid any contact with microbial products.

Although natural and generally very safe, wear gloves, face masks and protective clothing when mixing.  Wash your hands after use.
