Product Introduction
As a second-generation neonicotinoid systemic agricultural insecticide, Thiamethoxam Powder interferes with insect nicotinic acetylcholine receptor activity to block nerve signal transmission. It is rapidly absorbed by crop roots and foliage and translocated bidirectionally within plant tissues. It effectively controls piercing-sucking pests including aphids, whiteflies, thrips and planthoppers across grains, vegetables and fruit trees. As a core technical raw material for seed treatment, soil drench and foliar spray formulations, it helps growers suppress pest populations and reduce crop yield losses.

Health Benefits & Values
Nicotinic Receptor Mediated Insect Neurotoxicity
Metabolized in insects to clothianidin, which binds to nicotinic acetylcholine receptors, disrupting nerve signaling to paralyze and kill piercing-sucking pests.
Rapid Absorption & Bidirectional Translocation
Quickly taken up by roots and leaves, moving both upward and downward inside crops for full-plant protection.
Long-Lasting Residual Activity
Stably retained in plant vascular tissues after application, providing sustained defense against successive pest infestations.
Broad Control Spectrum for Sap-Feeding Pests
Delivers reliable control of aphids, whiteflies, planthoppers and thrips that damage crops by sucking plant sap.
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 (acute oral LD50: 0.005 μg a.i./bee). Its primary metabolite clothianidin exhibits comparable toxicity to honey bees. Avoid application during flowering periods and near apiaries. Toxic to aquatic organisms; keep away from water bodies.
Core Value in Formulation Development
High-Purity Technical Reduces Formulation Hazards
The ≥98% high-purity Thiamethoxam 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 insecticides of 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, rice 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, delivering long-term protection against 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
Second-Generation Neonicotinoid Positioning
Broader adaptability for seed treatment scenarios compared with first-generation neonicotinoids.
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.
Extended Residual Effect Reduces Application Frequency
Thiamethoxam Powder delivers long-duration protection, cutting spraying frequency and lowering labor costs for field and greenhouse growers.
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 Thiamethoxam 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 days to several months. Under aerobic conditions, it can persist 80–300 days in some soils. Plan crop rotation accordingly, especially for crops sensitive to neonicotinoid residues.
Q2: What is the toxicity of Thiamethoxam to bees and other pollinators?
A: Thiamethoxam is highly toxic to bees. Acute oral LD50 is approximately 0.005 μg a.i./bee. Its primary metabolite clothianidin exhibits comparable toxicity. Avoid application during flowering periods and near apiaries. It also has sublethal effects on bee learning and foraging behavior.
Q3: How does Thiamethoxam compare to Imidacloprid in terms of systemic movement?
A: Thiamethoxam is a second-generation neonicotinoid with bidirectional translocation, moving both upward and downward in plant tissues. Imidacloprid is first-generation, mainly with upward (acropetal) translocation. Thiamethoxam is also metabolized to clothianidin in insects, which contributes to its rapid knockdown effect.
Q4: Can Thiamethoxam be used for seed treatment on all crops?
A: Thiamethoxam 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 Thiamethoxam with other agrochemicals?
A: Thiamethoxam is stable under neutral and weakly acidic conditions (pH 5–7). Avoid mixing with strongly alkaline pesticides (pH > 8) to prevent decomposition. A small-scale jar test is recommended before large-volume mixing.
Q6: Does Thiamethoxam have any plant growth regulatory effects?
A: No. Unlike some triazole fungicides, Thiamethoxam is a neonicotinoid insecticide and does not exhibit plant growth regulatory activity. Its effects are limited to insect nervous system disruption.
Q7: How should Thiamethoxam 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. Thiamethoxam is stable for at least 2 years under proper storage conditions. Avoid mixing with alkaline substances.
Q8: Can Thiamethoxam 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 Thiamethoxam Powder and Thiamethoxam finished formulations?
A: Thiamethoxam 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 Thiamethoxam 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.
