What Is NAA 2.5% + IBA 3% SL?

NAA 2.5% + IBA 3% SL is an agricultural liquid rooting regulator containing two synthetic auxin-type active ingredients.

Its main commercial direction is the treatment of propagation material before planting into a suitable rooting substrate.

The product may be used in registered programs involving:

• Cutting propagation
• Cutting-base treatment
• Nursery plant multiplication
• Ornamental propagation
• Woody and semi-woody cuttings
• Other approved horticultural rooting programs

This product should not be presented as a general-purpose growth stimulant for every crop and growth stage.

Dual-Auxin Rooting Formulation

NAA and IBA both belong to the auxin plant growth regulator direction.

They do not provide two unrelated modes of action.

The correct positioning is:

A dual-auxin liquid formulation for registered cutting propagation and root-initiation programs.

The combination provides two auxin-type components in one finished product.

It should not be described as automatically stronger or more effective than an IBA-only formulation. Final performance depends on the plant species, variety, cutting maturity, treatment method and growing conditions.

How NAA and IBA Support Root Initiation

Adventitious roots form from plant tissues that do not normally function as roots.

A simple rooting process is:

Cutting-base treatment → Auxin response → Root primordium development → Adventitious root formation → Early root establishment

NAA and IBA may support the physiological response involved in this process.

The product does not create roots independently of the plant.

Successful propagation also depends on:

• Healthy stock plants
• Suitable cutting material
• Correct moisture
• Adequate oxygen
• Suitable temperature
• Clean rooting media
• Good drainage
• Correct humidity
• Disease control
• Post-treatment management

Role of IBA

IBA is widely used in professional plant propagation.

Its main function in the formulation is to support adventitious root initiation in suitable cutting material.

IBA may fit registered programs involving:

• Softwood cuttings
• Semi-hardwood cuttings
• Hardwood cuttings
• Herbaceous cuttings
• Ornamental propagation
• Nursery crop production
• Vine and shrub propagation

The response varies by species and variety.

IBA should not be described as guaranteeing successful rooting in every difficult-to-root plant.

Role of NAA

NAA is a synthetic auxin plant growth regulator.

In a rooting formulation, it provides additional auxin-type activity at the treated cutting base.

NAA response can be sensitive to concentration and exposure time.

Excessive treatment may contribute to:

• Heavy callus formation
• Delayed root emergence
• Root inhibition
• Cutting-base injury
• Uneven root development

Accurate measurement and controlled treatment are therefore important.

Main Use Direction: Cutting Propagation

Cutting propagation is the primary application direction for NAA 2.5% + IBA 3% SL.

Depending on local registration, the product may be positioned for professional propagation of:

• Ornamental plants
• Nursery crops
• Shrubs
• Vines
• Selected woody plants
• Selected herbaceous plants
• Other approved propagation materials

The treatment is normally directed at the lower part of the cutting.

The treated material must then be placed in a clean, suitable and well-managed rooting environment.

Softwood Cuttings

Softwood cuttings are taken from young, actively growing shoots.

They normally have tender tissues and can absorb treatment quickly.

Important considerations include:

• High sensitivity to excessive concentration
• High sensitivity to long contact time
• Rapid water loss
• Dependence on humidity control
• Need for clean propagation conditions

A treatment suitable for mature woody cuttings may damage tender softwood material.

Semi-Hardwood Cuttings

Semi-hardwood cuttings are taken from partly matured shoots.

They are common in nursery, shrub, vine and ornamental propagation.

Their response can depend on:

• Collection season
• Shoot maturity
• Stock-plant condition
• Cutting position
• Variety
• Rooting temperature

Treatment directions for softwood cuttings should not be copied automatically to semi-hardwood material.

Hardwood Cuttings

Hardwood cuttings are taken from mature, lignified shoots.

They may:

• Absorb the treatment differently
• Require a different concentration
• Require a different contact time
• Take longer to initiate roots
• Respond differently by species

A hardwood treatment should not be used on tender cuttings without crop-specific confirmation.

Herbaceous Cuttings

Herbaceous cuttings come from soft, non-woody plants.

They may respond quickly, but they can also be sensitive to excessive auxin exposure.

Important factors include:

• Cutting age
• Stem condition
• Leaf area
• Water loss
• Root-zone temperature
• Mist frequency
• Disease pressure
• Treatment concentration

A limited trial is recommended when the plant response is not already established.

Treatment Methods Are Different

Different propagation methods require different concentrations and contact times.

They must not be treated as interchangeable.

Quick Dip

A quick dip normally treats the lower cutting base for a short period.

The treatment may use a more concentrated solution than an extended soak.

Important controls include:

• Dipping depth
• Contact time
• Solution concentration
• Solution cleanliness
• Crop sensitivity

Longer contact with a quick-dip concentration may cause injury.

Extended Basal Soak

An extended basal soak treats the cutting base for a longer period.

It normally requires a different concentration from a quick dip.

The soaking time, treatment depth and solution strength must follow the approved label.

Other Registered Propagation Methods

Other treatment methods should only be included where they are supported by the product registration.

A cutting-base dip, long soak, root dip and root-zone application are different methods. Their rates and exposure times must not be exchanged.

Rooting Performance Depends on Propagation Conditions

A rooting regulator is only one part of a complete propagation program.

Root formation can be affected by:

• Plant species
• Variety
• Stock-plant health
• Cutting maturity
• Cutting position
• Collection season
• Cutting length
• Leaf number
• Leaf area
• Rooting substrate
• Drainage
• Humidity
• Irrigation
• Root-zone temperature
• Air temperature
• Light level
• Sanitation
• Disease pressure
• Post-treatment care

Poor-quality cuttings, waterlogged media or unsuitable temperatures can reduce rooting even when the product is applied correctly.

Limited Trial Before Commercial Treatment

A limited trial should be completed when:

• A new plant species is introduced
• A new variety is used
• The cutting type changes
• A different concentration is planned
• The treatment method changes
• A new substrate is used
• Environmental conditions change
• The product has not been used in the production system before

The trial may evaluate:

• Rooting percentage
• Time to root initiation
• Root number
• Root length
• Root distribution
• Root strength
• Callus formation
• Cutting survival
• Basal injury
• Uniformity

Commercial treatment should only be expanded after the response is acceptable.

More Product Does Not Mean Better Rooting

Auxin response is concentration-dependent.

A concentration that is too low may not provide the required response.

A concentration that is too high may cause:

• Excessive callus
• Root inhibition
• Basal tissue damage
• Delayed root development
• Weak roots
• Uneven rooting
• Cutting decline

Longer dipping time also increases total exposure.

The approved concentration and contact time should be followed carefully.

What This Product Does Not Do

NAA 2.5% + IBA 3% SL is not:

• A fertilizer
• A micronutrient
• A fungicide
• An insecticide
• A seed disinfectant
• A universal seed treatment
• A flowering regulator
• A fruit-thinning product
• A fruit-drop-control product
• A universal transplant treatment
• A guaranteed rooting solution
• A replacement for suitable propagation conditions
• A laboratory tissue-culture reagent

Its main identity should remain clear:

A liquid auxin rooting regulator for registered cutting propagation programs.

NAA + IBA Compared With IBA Alone

Product Direction	Main Positioning
NAA + IBA SL	Dual-auxin liquid rooting formulation
IBA Single Active	Focused IBA rooting regulator
NAA Single Active	Auxin regulator with rooting or other crop-specific uses depending on registration
6-BA + IBA	Cytokinin and auxin combination with different shoot-and-root positioning
IBA Powder	Dry rooting formulation for cutting-base treatment
Soluble IBA Formulation	Liquid preparation for approved rooting methods

NAA + IBA should not be described as universally stronger than IBA alone.

The correct product depends on the crop, cutting type, propagation method and local registration.

Difference Between NAA + IBA and 6-BA + IBA

These two combinations have different physiological positioning.

NAA + IBA

Both active ingredients are auxin-type regulators.

The main direction is:

• Root initiation
• Cutting propagation
• Adventitious root formation
• Professional rooting programs

6-BA + IBA

6-BA is a cytokinin, while IBA is an auxin.

This combination may be positioned around a different balance between shoot-related and root-related growth responses.

The two products should not be presented as interchangeable.
