Emamectin Benzoate 5%WDG

Active Ingredient: Emamectin Benzoate

CAS Number: 155569-91-8

Molecular Formula: C₄₉H₇₅NO₁₃

Classification: Systemic insecticide from the avermectin class (derived from Streptomyces avermitilis)

Primary Use: Controls lepidopteran larvae, thrips, borers, and other leaf-eating pests in vegetables, fruits, cotton, and ornamentals.

Mode of Action

Mechanism:
- Binds to glutamate-gated chloride channels in insect nervous systems → disrupts nerve impulses → paralysis and death.
- Translaminar activity: Penetrates leaf tissues to target pests on both leaf surfaces (ingestion or contact).
Speed of Action: Pests exhibit paralysis within hours; mortality occurs within 24–48 hours.

Key Features & Benefits

Systemic & Translaminar: Protects both upper/lower leaf surfaces and new growth.
Broad-Spectrum Efficacy: Targets lepidopterans (e.g., armyworms, codling moth), thrips, and leaf miners.
Low Toxicity: Safe for beneficial insects (e.g., ladybugs, parasitic wasps) when used as directed.
Long Residual: Provides 10–15 days of protection; reduces application frequency.
IPM-Compatible: Suitable for integrated pest management due to minimal impact on non-target species.

Application Guidelines

Mixing:
- Dilute in water according to crop/pest (e.g., 5–10g/ha for 5%WDG).
- Tank-mix compatible with fungicides (e.g., mancozeb) and other insecticides (jar test recommended).
Timing:
- Apply during early morning/late afternoon to avoid pollinators.
- Avoid flowering stages to protect bees.
Environmental Notes:
- Toxic to fish and aquatic life; keep 100m away from water bodies.
- Moderate soil persistence (degrades via microbial activity).

Safety & Storage

Personal Protection: Wear gloves, goggles, and respiratory masks; avoid skin/eye contact.
Storage:
- Cool (5–30°C), dry, sealed container; protect from sunlight.
- Shelf life: 2–3 years under proper conditions.
Disposal: Follow local regulations; do not contaminate water/soil.

Regulatory & Technical Notes

IRAC Group: 6 (avermectins); rotate with other modes of action (e.g., Group 1, 28) to prevent resistance.
Residue Compliance: Meets EU MRLs (e.g., 0.01–0.1 mg/kg for fruits/vegetables) and USDA standards.

Emamectin Benzoate FAQ

1. What is Emamectin Benzoate?

Emamectin Benzoate is a broad-spectrum insecticide derived from avermectin, a natural compound produced by the soil bacterium Streptomyces avermitilis. It belongs to the avermectin class and is widely used in agriculture to control lepidopteran pests, thrips, and leaf miners. Its low mammalian toxicity and rapid soil degradation make it environmentally friendly.

2. How does Emamectin Benzoate work?

Mode of Action: Binds to glutamate-gated chloride channels in insect nervous systems, disrupting nerve impulses and causing paralysis and death.
Translaminar Activity: Penetrates plant tissues to protect both upper and lower leaf surfaces, targeting pests that feed on treated or untreated areas.

3. What pests does Emamectin Benzoate control?

Primary Targets: Lepidopteran larvae (e.g., diamondback moth, armyworms, codling moth), thrips, leaf miners, bollworms, and ash borers.
Secondary Control: Some mite species (depending on formulation).

4. Which crops is it suitable for?

Agricultural Crops: Vegetables (tomatoes, cabbages), fruits (apples, citrus), cotton, paddy, tea plantations, and ornamentals.
Aquaculture: Controls ectoparasites like sea lice in fish farming.

5. What are the common formulations?

WDG (Water Dispersible Granules): 5%, 11.6%, 30%, 5.7%.
EC (Emulsifiable Concentrate): 19g/L, 20g/L, 50g/L.
Others: Microemulsion (ME), Dust Flowable (DF), Technical Concentrate (TC).

6. What is the recommended dosage?

General Range: 5–10 g/ha (varies by formulation and crop).
- Cotton: 200–300 ml/ha (1.9% EC).
- Vegetables: 150–250 ml/ha (5% WDG).
Always refer to product labels for crop-specific rates.

7. Is Emamectin Benzoate safe for beneficial insects?

Selective Action: Generally safe for ladybugs, parasitic wasps, and bees (when applied during non-flowering periods).
Precautions: Avoid spraying during peak pollinator activity or near beneficial insect habitats.

8. How long does its effect last?

Residual Activity: 10–15 days, depending on crop type, weather (rain/UV exposure), and pest pressure.
Translaminar protection ensures sustained control of pests on treated plants.

9. Can it be mixed with other pesticides?

Compatibility: Yes, with fungicides (e.g., mancozeb, carbendazim) and other insecticides.
Caution: Perform a jar test to check for physical/chemical incompatibilities before mixing.

10. What safety precautions should be taken?

Personal Protection: Wear gloves, goggles, and respiratory masks; avoid skin contact and inhalation.
Environmental Safety:
- Toxic to fish and aquatic life; keep away from water sources.
- Apply in calm weather to prevent drift.
Storage: Store in a cool, dry place, away from food and children.

11. Is Emamectin Benzoate systemic?

Translaminar, Not Fully Systemic: It penetrates leaf tissues but does not translocate throughout the entire plant. Effective against pests on both leaf surfaces.

12. How to manage resistance to Emamectin Benzoate?

Rotation: Use with insecticides from different IRAC groups (e.g., Group 1, 28) to avoid resistance.
Integrated Pest Management (IPM): Combine with biological controls and cultural practices.
