Agricultural Disinfectant/ Plant Sanitiser


A contact active liquid agricultural disinfectant / plant sanitiser, active against pathogenic micro-organisms bacteria.

General Information

The Disinfectant Registration of Nuron-BioSafe is in accordance to the relevant local legislation. However, if the crop has been treated and is intended for export purposes, beforehand please consult the relevant importer or exporter of the destination country for more information & nation about the use of this product and maximum residue limits.

  • Nuron-BioSafe, is stable, effective, not pH dependable and can therefore be used with irrigation.
  • Nuron-BioSafe stays active as long as it is in solution.
  • Nuron-BioSafe has wetting  characteristics.

Growing medium (Inert- or non-organic), equipment such as pruning shears, ploughs hands, footbaths, etc.

General Instructions

Cold rooms and packing houses Greenhouses, seed trays, other hard surfaces like picking bins, etc.

The disinfectant Nuron-BioSafe Can be applied as a plant & sanitiser to reduce the overall pathogenic load on the foliage without leaving any residual activity.

First time application to disinfect wet-walls, give a shock treatment of 100 – 150mls of Nuron-Biosafe per litre of water. Thereafter continue with dosage as recommended.


IMPORTANT: Nuron-BioSafe should be incorporated into a normal fungicidal programme for adequate disease control.

Dipping Tanks: 5 – IOml post harvest

Dip for 2 – 5 minutes. Replace Nuron-BioSafe when the solution becomes transparent. To ensure quality control is maintained keep Nuron-BioSafe concentration at recommended rate.


Tool Disinfection: 70 – 90ml per litre

Make sure that all surfaces are exposed to the Nuron-BioSafe solution. First remove all organic matter from surfaces.

Treating water in spray tanks to be used as a foliage spray to sanitise plant surfaces: 5 – 10ml per litre

For optimum results allow treated water to be exposed to Nuron-Biosafe for at least 20mins. This will help to dramatically reduce bacteria and fungi counts including coliforms and E coli in the water.

(This rate will vary with plant size)

Irrigation: for use in nurseries, greenhouses, misting systems, etc.

Rinse irrigation pipes frequently when dosing for the first few times The dirt/algae/organic matter will be discharged and may clog the drippers or spitters. Nuron-BioSafe can be used in fertigated water. Take note: The cleaner the water to be treated the better the results.

IMPORTANT: Although numerous phytotoxicity trials were done it is impossible to verify the sensitivity of all the different crops varieties to Nuron-BioSafe. It is therefore recommended to first test KNOWN agrochemical sensitive varieties before use on big scale.

Nuron-BioSafe can be used in post-harvest dump tanks to assists in post-harvest decay management by killing pathogens in drenches and dump tanks as well as on fruit surfaces. IMPORTANT: Nuron-BioSafe leaves no residual activity. For effective disease control registered fungicides must still be used. Fruit and vegetables must not be left in dump tank during any disruption of production. This could result in serious burning of sensitive fruit.

Water for post-harvest treatment of cut flowers in containers.

The solution can be used 7 to 10 days if kept clean. Do not keep cut flowers in solution for longer than 72 hours.

Do not use Nuron-BioSafe in hot water fungicide dipping tanks This may result in serious burning of sensitive fruit.

Nuron-BioSafe is recommended for use in many greenhouse and nursery applications including:

General sanitation Nuron-BioSafe is an effective high-level treatment for eradication of bacteria, algae, fungi, and other harmful plant pathogens on contact. Nuron-BioSafe is recommended for use with pots, tools, structures, trays, gravel/dirt walkways, concrete walkways, irrigation lines and stock tangs. Nuron-BioSafe is completely safe for plans, making it idea for greenhouse applications.

Seed treatment and vegetative cutting Nuron-BioSafe is recommended for surface treatment of vegetative cuttings and seeds to kill harmful fungal and bacterial plant pathogens.

Direct injection for Propagation

Inject Nuron-BioSafe through mist lines to treat cuttings and plugs while simultaneously clearing line-clogging biofilms and algae.

Drench Treatments

Regularly treat non-soil material with Nuron-BioSafe to maintain low disease pressures. Nuron-BioSafe is recommended as both a curative and preventive application for young plant material.

Water Treatment

Apply Nuron-BioSafe to help stop cross-contamination in recycled water systems and stored water systems.

Specially formulated to eradicate bacteria, algae, fungi and spores on contact. Nuron-BioSafe is recommended as a curative, preventive, treatment in the soil. Nuron-BioSafe is also recommended for us in gardens, nurseries, greenhouses and orchards for a wide variety of horticultural applications such as direct injection, cold or thermal fog, vegetative cutting and seed treatment, drench treatment, water treatment, flowering plants. Nuron-BioSafe is also recommended for use as an algaecide and fungicide on: greenhouse structures, pots, benches, water systems, storage rooms, evaporative coolers, floors, ventilation equipment and other equipment.

Nuron-BioSafe is mutation resistant because its rapid oxidation on surface contact with plants and materials helps stop the development of tolerant stains of fungi and bacteria.

  • Zero hour re-entry interval (REI)
  • Kills bacteria, algae, fungi and spores on contact
