Comprehensive analytical insight into Emamectin Benzoate (CAS No. 155569-91-8)
Emamectin Benzoate is an advanced semi-synthetic derivative of Avermectin B1, synthesized via the multi-step chemical modification of the natural fermentation product of Streptomyces avermitilis. By introducing a methylamino group at the 4''-position of the oleandrose ring followed by salt formation with benzoic acid, the resulting molecule exhibits dramatically heightened potency against target Lepidopteran pests while optimizing environmental stability.
Classified under IRAC Group 6, Emamectin Benzoate functions as a high-affinity allosteric modulator of glutamate-gated chloride channels (GluCl) and gamma-aminobutyric acid (GABA) receptors in insect nervous systems. This binding causes an irreversible influx of chloride ions into neuromuscular cells, depolarizing membrane potential, blocking nerve signal transmission, and causing immediate cessation of feeding followed by irreversible flaccid paralysis.
Upon foliar application, Emamectin Benzoate rapidly penetrates leaf cuticles via translaminar movement, forming an internal active reservoir within plant mesophyll tissues. This unique movement shields the active ingredient from rapid photodegradation caused by solar UV radiation, ensuring prolonged residual efficacy against hidden foliar feeders, leafminers, and stem borers for up to 14–21 days post-application.

How state-of-the-art Chinese manufacturing hubs deliver competitive pricing without compromising quality.
China commands over 80% of global primary fermentative capacity for Avermectin B1 crude stock. By establishing direct pipeline access to high-yielding Streptomyces strains and localized carbohydrate feedstocks in northern China, our manufacturing facilities mitigate international price volatility, secure steady precursor supply, and guarantee stable volume outputs during peak global agricultural seasons.
Our automated synthesis lines utilize continuous crystallization technology, real-time online High-Performance Liquid Chromatography (HPLC) monitoring, and closed-loop solvent recovery units. This guarantees batch-to-batch consistency with active substance purity frequently exceeding 96.5%, minimal isomer impurities, and zero organic solvent residues in final solid formulations.
Transparent pricing models tailored for B2B importers, formulators, and institutional procurement agents.
Emamectin Benzoate quotes fluctuate based on raw material precursor costs (Avermectin B1), formulation type (TC vs. WDG/EC), custom packaging, and order volumes. We offer transparent quotation structures including FOB Tianjin/Qingdao, CIF worldwide destination ports, and DDP turnkey logistics. Volume discounts apply to annual contract orders exceeding 5 Metric Tons TC equivalent.

Agronomic protocols for optimizing control efficiency while suppressing insect resistance development.
Emamectin Benzoate is the primary defense against economic Lepidopteran threats across global crop sectors:
• Fall Armyworm (Spodoptera frugiperda) in Corn: 5.0–7.5 g a.i./ha (5% WDG at 100–150 g/ha). Apply during early instar stage.
• Diamondback Moth (Plutella xylostella) in Brassicas: 3.6–4.8 g a.i./ha. Exceptional activity against organophosphate-resistant populations.
• Cotton Bollworm (Helicoverpa armigera): 7.5–10 g a.i./ha. High stomach poison activity prevents larval fruit penetration.
• Tomato Leafminer (Tuta absoluta): 5.0–8.0 g a.i./ha. Rapid translaminar penetration controls leaf miners inside tissues.
Continuous sole use of IRAC Group 6 insecticides increases resistance risks. To preserve field longevity:
1. Mode of Action Rotation: Alternate Emamectin Benzoate with Diamides (Group 28), Spinosyns (Group 5), or Pyrethroids (Group 3A).
2. Adjuvant Enhancement: Combining formulations with non-ionic organosilicone surfactants reduces surface tension, speeds cuticular penetration, and doubles rainfastness within 30 minutes of application.
3. Spray Water pH Control: Maintain spray solution pH between 5.5 and 7.0. Alkaline water (pH > 8.0) causes rapid alkaline hydrolysis of the benzoic acid salt.
