Dinotefuran 20% SG: Systemic Neonicotinoid Insecticide for Aphid, Whitefly and Leafhopper Control

Introduction

Dinotefuran 20% SG is a systemic neonicotinoid insecticide widely used for the control of important sucking and certain chewing insect pests in agricultural crops.

The active ingredient is:

Dinotefuran — 20%

Typical formulation:

SG — Water Soluble Granule

Dinotefuran belongs to:

IRAC Group 4A — Neonicotinoids

According to IRAC, Dinotefuran acts as a:

Nicotinic Acetylcholine Receptor (nAChR) Competitive Modulator

and disrupts normal insect nerve transmission.

EPA identifies Dinotefuran as an insecticide used against pests including:

• Aphids

• Whiteflies

• Thrips

• Leafhoppers

• Scales

• Leaf miners

• Other susceptible insects

on agricultural crops such as leafy vegetables, root vegetables, berries, cereal crops and oilseed crops including cotton.

Its core positioning can be summarized as:

Systemic Activity + Strong Sucking Pest Control + Rapid Feeding Suppression + Flexible Crop Protection

What Is Dinotefuran?

Dinotefuran is a neonicotinoid insecticide developed for broad-spectrum insect pest management.

It belongs to the same IRAC subgroup as:

• Imidacloprid

• Acetamiprid

• Thiamethoxam

• Clothianidin

All of these are classified in:

IRAC Group 4A

because they act on nicotinic acetylcholine receptors in the insect nervous system.

Dinotefuran is especially valued for its activity against sucking insect pests that feed on plant sap.

How Does Dinotefuran Work?

Dinotefuran affects the insect nervous system.

Insects use the neurotransmitter:

Acetylcholine

to transmit nerve signals.

Dinotefuran interacts with:

Nicotinic Acetylcholine Receptors — nAChRs

and causes abnormal continuous stimulation of the insect nervous system.

The process can be summarized as:

1. Dinotefuran enters the insect.

2. It binds to nicotinic acetylcholine receptors.

3. Normal nerve signaling is disrupted.

4. Continuous nerve stimulation develops.

5. Feeding activity declines.

6. Coordination is lost.

7. Paralysis and mortality occur.

IRAC classifies this action as:

Group 4 — nAChR Competitive Modulators.

Why Is Dinotefuran Systemic?

Dinotefuran can be absorbed by plants and move within treated tissues.

This systemic behavior helps protect plant parts beyond the exact spray deposit.

Depending on the registered product, Dinotefuran may be used through:

• Foliar application

• Soil application

• Other registered delivery methods

EPA's original Dinotefuran fact sheet lists formulation and application approaches including soluble granules, concentrates, soil incorporation and foliar application.

Systemic movement is especially valuable for sucking insects because they feed directly from plant tissues.

Which Insects Can Dinotefuran Control?

Dinotefuran has activity against a broad range of susceptible insect pests.

EPA specifically identifies target pests including:

• Aphids

• Whiteflies

• Thrips

• Leafhoppers

• Scales

• Leaf miners

• Mealybugs

• Beetles

• Certain larvae

• Other susceptible pests.

The actual control spectrum depends on:

• Crop

• Product formulation

• Application method

• Pest stage

• Local registration

Aphid Control

Aphids are important sucking pests in many crops.

They damage plants by:

• Removing plant sap

• Weakening new growth

• Causing leaf curling

• Producing honeydew

• Supporting sooty mold development

• Transmitting some plant viruses

Dinotefuran's systemic activity allows the active ingredient to reach feeding aphids through treated plant tissue.

This makes it especially useful when aphid colonies occur on:

• Young leaves

• New shoots

• Protected plant surfaces

Whitefly Control

Whiteflies are among the most important targets for Group 4A insecticides.

They can cause:

• Sap loss

• Leaf yellowing

• Honeydew accumulation

• Sooty mold

• Virus transmission

• Reduced crop quality

IRAC has developed specific resistance-management guidance for neonicotinoid use against whiteflies because species such as Bemisia tabaci have a high capacity to develop resistance.

Dinotefuran can provide strong control where populations remain susceptible, but repeated Group 4A use should be avoided.

Leafhopper Control

Leafhoppers feed by piercing plant tissue and removing sap.

Some species also transmit important crop diseases.

EPA identifies leafhoppers among the agricultural pests controlled by Dinotefuran.

Systemic activity can help reach insects feeding on:

• Leaf veins

• Young shoots

• Lower leaf surfaces

Good crop monitoring remains important because early treatment usually provides more reliable results.

Thrips Control

Thrips can cause:

• Silvering

• Scarred leaves

• Deformed young growth

• Flower damage

• Fruit scarring

• Virus transmission

Dinotefuran is listed by EPA among insecticides used against thrips.

However, thrips control can be influenced strongly by:

• Pest stage

• Flower protection

• Resistance status

• Application timing

Therefore, early scouting is especially important.

Why Is Early Application Important?

Sucking pest populations can increase rapidly under favorable conditions.

Early application can help prevent:

• Colony expansion

• Severe feeding damage

• Honeydew accumulation

• Virus transmission

• Secondary crop stress

The goal should be:

Control Early Before Populations Become Difficult to Manage

rather than waiting until severe infestation develops.

Why Is Good Coverage Still Important?

Systemic activity does not eliminate the need for good spray coverage.

Foliar applications still depend on sufficient deposition for initial uptake.

Poor spray coverage may result in:

• Uneven absorption

• Slower control

• Untreated areas

• Surviving pest populations

Important application factors include:

• Correct nozzle

• Spray volume

• Canopy penetration

• Equipment calibration

• Timing relative to pest location

How Quickly Does Dinotefuran Work?

Dinotefuran acts directly on insect nerve function.

One of the first effects is often:

Reduced Feeding Activity

followed by:

• Loss of coordination

• Paralysis

• Mortality

Actual speed depends on:

• Pest species

• Pest stage

• Application method

• Dose

• Temperature

• Resistance level

Users should evaluate control according to the registered label and actual field conditions.

Why Is Dinotefuran Useful Against Hidden Sucking Pests?

Many sucking pests are difficult to reach with contact-only insecticides because they may occur:

• Under leaves

• Inside dense canopies

• Around young shoots

• In concealed feeding sites

Systemic movement can help improve exposure after the active ingredient is absorbed into the plant.

This is one of the major reasons Dinotefuran is valued in:

• Vegetable crops

• Cotton

• Fruit crops

• Ornamentals

• Other registered systems

Resistance Management

Dinotefuran belongs to:

IRAC Group 4A

Resistance management is important because many sucking pests have developed resistance to neonicotinoid insecticides in different regions.

IRAC's Group 4 guidance states that insecticides in this group principally share the same nicotinic acetylcholine receptor binding site and should be managed carefully to reduce resistance selection.

A good resistance-management program should include:

• Rotation with different IRAC groups

• Avoiding repeated Group 4A applications

• Using economic thresholds

• Field scouting

• Biological control

• Correct application rates

• Investigating surviving populations

Why Changing Between Neonicotinoids Is Not True Rotation

This is an important technical point.

Active ingredients such as:

• Dinotefuran

• Imidacloprid

• Thiamethoxam

• Acetamiprid

• Clothianidin

all belong to:

IRAC Group 4A

Therefore, switching from Dinotefuran to another Group 4A active ingredient does not provide a true mode-of-action rotation.

IRAC specifically groups these active ingredients together because they share the same primary target site.

A stronger rotation should involve insecticides from genuinely different IRAC groups.

Whitefly Resistance Management

Whiteflies deserve special attention.

IRAC notes that Bemisia tabaci and Trialeurodes vaporariorum have significant resistance-development potential and recommends integrated whitefly management rather than continuous neonicotinoid use.

Useful practices include:

• Rotate different IRAC groups

• Preserve natural enemies

• Avoid unnecessary applications

• Remove heavily infested plant material where practical

• Control alternate hosts

• Use biological control in protected crops where appropriate

Beneficial Insects and Pollinators

Dinotefuran is a neonicotinoid insecticide, so responsible use around beneficial insects is important.

Application programs should follow label restrictions related to:

• Pollinating insects

• Flowering crops

• Drift

• Water protection

• Application timing

EPA completed updated endangered-species biological evaluations for Dinotefuran in October 2024, reflecting continued regulatory attention to environmental effects.

Users should always follow the current registered label in the destination market.

Integrated Pest Management

Dinotefuran works best as part of an Integrated Pest Management program.

Useful practices include:

• Regular scouting

• Accurate pest identification

• Economic thresholds

• Biological control

• Removal of heavily infested material

• Resistant crop varieties where available

• Mode-of-action rotation

• Selective insecticide use

The goal is not simply to apply more insecticide.

The goal is to maintain pest populations below economically damaging levels while reducing resistance pressure.
