Chemical Insecticide Emamectin Benzoate 5% + Lufenuron 40% WDG Purity

I. Basic Product Information

Generic Name: 5% Emamectin Benzoate + 40% Lufenuron Water Dispersible Granules (WDG)

Formulation: WDG (Water Dispersible Granules)

Active Ingredient Content: Emamectin Benzoate 5%, Lufenuron 40%

Product Characteristics: This product is a highly effective, broad-spectrum compound insecticide. It combines the rapid insecticidal action of emamectin benzoate with the long-lasting ovicidal and molting-inhibiting properties of lufenuron, offering multiple modes of action including contact toxicity, stomach toxicity, and penetrative/systemic activity. The WDG formulation features excellent water solubility, produces no dust, has a high suspension rate, and offers good crop compatibility with a low risk of phytotoxicity and high rain-fastness. Specifically designed to target stubborn and resistant Lepidopteran pests, it delivers both rapid knockdown and long-term control, effectively overcoming pest resistance issues.

IRAC Codes: Emamectin Benzoate (Group 6) and Lufenuron (Group 15); the combination of different modes of action provides excellent resistance management.

II. Core Modes of Action (Dual Mechanisms & Synergistic Effect)

1. Mode of Action: 5% Emamectin Benzoate

Acts primarily through stomach toxicity and contact toxicity, with slight penetrative activity, targeting the pest's nervous system. It works by activating glutamate-gated chloride channels and promoting the release of gamma-aminobutyric acid (GABA), thereby inhibiting normal nerve signal transmission and disrupting the pest's neurological regulatory functions. Upon contact with or ingestion of treated plant tissue, pests exhibit symptoms such as paralysis, cessation of feeding, and immobility within hours, eventually dying from neurological failure and starvation. It offers rapid action, quickly halting feeding damage, and is highly effective against late-instar larvae and active pests.

2. Mode of Action: 40% Lufenuron

An insect chitin synthesis inhibitor (insect growth regulator) that acts primarily through stomach toxicity, contact toxicity, and ovicidal activity. While it does not provide rapid knockdown, it offers an exceptionally long residual effect. By inhibiting the activity of chitin synthase in pests, it disrupts the formation of chitin in their cuticles and eggshells. This prevents larvae from molting, pupating, or emerging as adults, and stops eggs from hatching, thereby cutting off the pest's reproductive cycle at the source. Additionally, it inhibits adult oviposition and reduces egg viability, providing long-term suppression of pest populations and effectively preventing recurring outbreaks.

3. Synergistic Advantages of the Formulation

It combines rapid knockdown with long-lasting egg control; it quickly kills existing adults and larvae while continuously suppressing egg hatching and larval molting/reproduction, effectively disrupting the pest's life cycle at two stages. The two active ingredients operate via completely different mechanisms with no cross-resistance, significantly enhancing efficacy against resistant pests—offering long-lasting crop protection from a single application.

III. Applicable Crops

Suitable for a wide range of cash crops, grain crops, fruits, and vegetables, offering broad compatibility and high safety:

• Vegetables: Cruciferous, Solanaceous, and Leguminous vegetables such as cabbage, Chinese cabbage, cauliflower, chili peppers, tomatoes, cucumbers, green beans, and lettuce;
• Fruit trees: Citrus, apples, pears, grapes, strawberries, mangoes, and other fruit-bearing trees;
• Grain and cash crops: Corn, cotton, rice, peanuts, soybeans, potatoes, etc.;
• Other crops: Flowers, nursery stock, medicinal herbs, etc.

IV. Target Pests

Primarily targets various resistant Lepidopteran pests while also controlling certain Coleoptera and piercing-sucking pests, providing comprehensive control of both insects and eggs:

Core targets (highly effective): Diamondback moth, beet armyworm, Spodoptera litura (cluster caterpillar), fall armyworm, cotton bollworm, rice leaf folder, corn borer, bean pod borer, melon worm, cabbage white butterfly larva, tobacco budworm, etc.;

Secondary targets: Leaf miners, thrips, leafhoppers, aphids, potato beetles, mite nymphs, and other small pests. It effectively controls pest damage such as leaf-chewing, leaf-rolling, fruit-boring, and stem-boring, thoroughly halting the spread and proliferation of infestations.

V. Official Recommended Dosage and Application Methods

1. Dilution Rates (Standard for Field Crops)

• Small-scale spraying (15L knapsack sprayer): 2.4–3.2g per mu; dilute in 15L of water and spray evenly.
• Large-scale field application (water volume of 200L per mu): 24–32g per mu.
• Per-hectare dosage: 100–120g/hectare; adjust dosage based on the severity of the infestation.

2. Application Guidelines by Scenario

• Mild infestation/Prevention phase: Use the lower dosage and spray evenly to suppress the pest population base and prevent outbreaks.
• Moderate/Severe/Resistant infestations: Use the higher dosage, focusing on areas with high pest density; apply at 7–10 day intervals for two consecutive applications to thoroughly eliminate pests and control eggs.
• Optimal application timing: Peak egg-hatching period or early larval stage; pests have lower resistance during these stages, ensuring maximum control efficacy.

3. Key Application Tips

1. This product is a water-dispersible granule (WDG). First, add a small amount of water to the sprayer, add the product, and stir thoroughly until dissolved; then add the remaining water and stir again to ensure a uniform mixture and prevent clumping.
2. Apply as a fine, even mist to the foliage, ensuring thorough coverage of the upper and lower leaf surfaces, tender shoots, fruits, and stems.
3. Avoid application during high-temperature midday periods, strong winds, or rainy weather; re-apply if rainfall occurs within 2 hours of application.
4. Can be mixed with most neutral or acidic pesticides and foliar fertilizers; do not mix with alkaline agents (such as lime sulfur mixture, Bordeaux mixture, etc.).

VI. Pesticide Application Safety Protocols

1. During application, personnel must wear long-sleeved protective clothing, rubber gloves, protective masks, goggles, and non-slip rubber boots at all times; direct skin contact with the pesticide and inhalation of spray mist are strictly prohibited.
2. Eating, smoking, or drinking is prohibited during operations to prevent accidental ingestion of the pesticide.
3. Pregnant women, nursing mothers, minors, and individuals in poor health are strictly prohibited from participating in pesticide mixing or application.
