Product Introduction
As a neonicotinoid systemic agricultural insecticide, Imidacloprid Powder targets insect nicotinic acetylcholine receptors to disrupt nerve signal transmission. It can be absorbed by crop roots and leaves with upward translocation inside plant tissues. It efficiently controls piercing-sucking pests such as aphids, whiteflies, thrips and planthoppers on grains, vegetables and fruit trees. As a core technical raw material for seed treatment, soil drench and foliar spray formulations, it helps growers reduce pest feeding damage and stabilize crop yield.

Health Benefits & Values
Nicotinic Receptor Targeting for Insect Neurotoxicity
Binds to insect nicotinic acetylcholine receptors, interrupting nerve impulse transmission and causing paralysis and death of piercing-sucking pests.
Systemic Uptake & Acropetal Translocation
Readily absorbed by roots and foliage, moving upward through vascular tissues to protect newly emerged plant tissues.
Long Residual Protective Effect
Maintains stable activity inside crop tissues after application, delivering sustained control against successive pest infestations.
Effective Against Piercing-Sucking Pest Group
Provides reliable control of aphids, whiteflies, planthoppers and thrips that damage crops via sap sucking.
High Purity Reduces Formulation Risks
Low impurity content lowers phytotoxicity risk and meets requirements for premium insecticide finished products.
Ecological Safety Considerations
Highly toxic to bees. Avoid application during flowering periods and near apiaries. Toxic to aquatic organisms; keep away from water bodies. Low toxicity to birds.
Core Value in Formulation Development
High-Purity Technical Reduces Formulation Hazards
The ≥96% high-purity Imidacloprid Powder adopts standardized purification process with low heavy metal and impurity content, lowering phytotoxicity risk and meeting requirements for premium insecticide finished products.
Formula Simplification for Sucking Pest Contro
Single active ingredient addresses piercing-sucking pests, reducing the need for multiple actives in finished formulations.
Multi-Dosage Form Process Adaptability
Suitable for wettable powder, water dispersible granule, suspension concentrate and seed coating formulations, matching seed dressing, soil irrigation and foliar spraying workflows.
Great Potential for Compound Formulation
Compatible with pyrethroids and other insecticides with different modes of action. Combined formulas broaden pest spectrum and delay pest resistance development.
Consistent Storage Stability
Crystalline structure maintains good chemical stability under dry, shaded storage, resisting decomposition and preserving stable efficacy throughout finished product shelf life.
End-Application Scenarios
Piercing-Sucking Pest Control (Core Track)
Controls aphids, whiteflies, planthoppers, thrips and leafhoppers on rice, wheat, vegetables, citrus and ornamental crops.
Seed Treatment Formulation
Processed into seed coating and seed dressing agents for early-season pest protection.
Soil Drench Application
Applied in nurseries and greenhouse substrates for root uptake, offering long-term protection against underground and early-stage aboveground pests.
Compound Insecticide Development
Serves as core active ingredient for mixed insecticide formulations, combining with other actives to expand control spectrum and manage resistance risk.
High-Value Horticulture & Field Crop Protection
Widely used for fruits, vegetables and grain crops, providing dependable sucking pest control for large-scale commercial planting systems.
Application Advantages and Market Positioning
Systemic Protection Differentiation
Provides internal plant protection for persistent sap-sucking pest management.
Unique Mode of Action for Resistance Rotation
Targets insect nicotinic receptors, suitable for rotation or compound use with non-neonicotinoid insecticides to slow pest resistance build-up.
Long-Lasting Protection Reduces Spraying Frequency
Imidacloprid Powder delivers extended residual effect, lowering application times and saving labor cost for growers in field and greenhouse production.
Wide Adaptability for Field & Protected Crops
Features reliable crop safety at recommended rates, matching pest control demands of grain fields, greenhouses and commercial orchards.
FAQ (Technical Q&A)
Q1: How long does Imidacloprid persist in soil, and what factors affect its residual activity?
A: Soil half-life varies widely depending on soil type, organic matter content, and climate, typically ranging from a few weeks to several months. It is relatively persistent in high-organic-matter soils. Plan crop rotation accordingly, especially for crops sensitive to neonicotinoid residues.
Q2: What is the toxicity of Imidacloprid to bees and other pollinators?
A: Imidacloprid is highly toxic to bees. Acute contact toxicity (48h LC50) is approximately 0.065 μg a.i./bee. Avoid application during flowering periods and near apiaries. It also has sublethal effects on bee learning and foraging behavior.
Q3: How does Imidacloprid compare to Bifenthrin in terms of pest spectrum and application?
A: Imidacloprid is a systemic neonicotinoid targeting piercing-sucking pests (aphids, whiteflies, planthoppers) with root and foliar uptake. Bifenthrin is a contact pyrethroid with both insecticidal and acaricidal activity, effective against a broader range of foliar pests but without systemic movement. They can be used in complementary spray programs.
Q4: Can Imidacloprid be used for seed treatment on all crops?
A: Imidacloprid is registered for seed treatment on rice, wheat, cotton, corn, and vegetables. Follow local registration guidelines for specific crops. It is particularly effective for early-season control of soil and seed-borne sucking pests.
Q5: What is the optimal pH range for tank-mixing Imidacloprid with other agrochemicals?
A: Imidacloprid is stable under neutral and weakly acidic conditions (pH 5–11). Avoid mixing with strongly alkaline pesticides (pH > 8) to prevent decomposition. A small-scale jar test is recommended before large-volume mixing.
Q6: Does Imidacloprid have any plant growth regulatory effects?
A: No. Unlike some triazole fungicides, Imidacloprid is a neonicotinoid insecticide and does not exhibit plant growth regulatory activity. Its effects are limited to insect nervous system disruption.
Q7: How should Imidacloprid be stored to maintain stability?
A: Store in a sealed container in a cool, dry, ventilated warehouse away from heat, direct sunlight, and fire sources. Imidacloprid is stable for at least 2 years under proper storage conditions. Avoid mixing with alkaline substances.
Q8: Can Imidacloprid be used in greenhouse vegetable production?
A: Yes. It is widely used for greenhouse seed treatment and soil drench to control whiteflies and aphids. However, because of its high toxicity to bees, avoid application during crop flowering. Ensure adequate ventilation and follow pre-harvest intervals.
Q9: What is the difference between Imidacloprid Powder and Imidacloprid finished formulations?
A: Imidacloprid Technical is a raw material for pesticide manufacturers to produce finished formulations such as WP, WDG, SC, and seed coating agents. Finished formulations are ready-to-use products that require dilution before field application.
Q10: Does repeated use of Imidacloprid easily trigger pest resistance?
A: Repeated solo application may induce resistance. Rotation or compounding with insecticides of different action mechanisms (such as pyrethroids or diamides) is strongly recommended to delay resistance development.
