DDVP 1000EC 77.5%: Formula, CAS Number, Functions, Efficacy, Target Pests, Advantages, and Manufacturer Strengths

DDVP (Dichlorvos) 1000EC 77.5% is a highly potent organophosphorus insecticide and acaricide, widely recognized for its rapid action and broad-spectrum activity. Formulated as an emulsifiable concentrate (EC) with 77.5% active ingredient, it is a staple in agricultural, horticultural, and public health pest management. Below is a comprehensive overview of its key properties, performance, and competitive advantages, including insights into manufacturing strengths.

Chemical Formula and CAS Number

The chemical formula of DDVP is C₄H₇Cl₂O₄P, 

DDVP is registered under the CAS Number 62-73-7,

Core Functions and Mechanism of Action

DDVP 1000EC 77.5% acts primarily as a cholinesterase inhibitor, disrupting the nervous systems of insects and mites. It binds irreversibly to acetylcholinesterase, an enzyme critical for breaking down the neurotransmitter acetylcholine. This inhibition causes acetylcholine to accumulate, leading to continuous nerve impulses, muscle spasms, paralysis, and eventual death of the target pest.

Its functions extend beyond direct toxicity:

• Contact activity: Kills pests on direct contact with treated surfaces, making it effective against crawling and flying insects.

• Fumigant action: Releases volatile vapors that penetrate cracks, crevices, and enclosed spaces, reaching pests hidden in hard-to-reach areas (e.g., stored grain bins, crop canopies).

• Stomach toxicity: Lethal when ingested, ensuring efficacy against feeding pests.

Efficacy: Performance Metrics

DDVP 1000EC 77.5% is celebrated for its rapid knockdown and high mortality rates, with performance validated in diverse scenarios:

Speed of Action

Pests exposed to DDVP exhibit symptoms within minutes to hours. For example, flies and mosquitoes show paralysis within 5–15 minutes, with 90% mortality achieved within 30 minutes of exposure. This rapidity is critical for controlling outbreaks in public health settings or high-value crop environments.

Residual Activity

While its residual effect on foliage is short (1–3 days) due to volatility, this characteristic minimizes long-term environmental persistence. In enclosed spaces (e.g., warehouses, greenhouses), however, vapors can maintain efficacy for up to 1–2 weeks, providing sustained control of stored-product pests.

Control Efficacy

Field and lab trials demonstrate consistent performance:

• Agricultural settings: Achieves 90–95% mortality against target pests, reducing crop damage by 70–80% when applied correctly.

• Public health: Reduces mosquito and fly populations by 85–90% in treated areas, lowering disease transmission risks.

Target Pests

DDVP 1000EC 77.5% targets a wide range of insects and mites, including:

• Agricultural pests: Aphids, thrips, whiteflies, caterpillars (e.g., armyworms, bollworms), leafhoppers, mites, and beetles (e.g., Colorado potato beetles).

• Stored-product pests: Grain weevils, flour beetles, grain moths, and warehouse beetles.

• Public health pests: Mosquitoes, house flies, cockroaches, bed bugs, and fleas.

• Livestock pests: Ticks, lice, and stable flies, protecting animals from infestations and disease.

Key Advantages

1. Broad-Spectrum Activity: Controls insects, mites, and even some nematodes, eliminating the need for multiple products.

2. Rapid Knockdown: Critical for urgent pest outbreaks, preventing immediate crop loss or health risks.

3. Fumigant Properties: Reaches hidden pests in cracks, soil, or stored goods, where contact insecticides fail.

4. Versatile Application: Suitable for foliar sprays, soil drenches, space fumigation, and livestock premise treatments.

5. Cost-Effective: High concentration (77.5%) reduces application volume, lowering transportation and handling costs.

6. Compatibility: Mixes well with most pesticides and adjuvants, enhancing flexibility in integrated pest management (IPM) programs.

Manufacturer Strengths

• Quality Control: Adherence to strict international standards (e.g., FAO, EPA) ensures consistent potency and purity. Advanced lab testing verifies active ingredient concentration and stability.

• Production Capacity: Large-scale manufacturing facilities with automated lines enable high-volume output, meeting global demand with short lead times.

• Regulatory Compliance: Expertise in navigating global registration requirements, ensuring product approval in major agricultural and public health markets.

• Technical Support: Dedicated teams provide application guidelines, dosage recommendations, and pest management strategies, assisting customers in optimizing efficacy.

• Sustainability Practices: Investment in eco-friendly production processes, reducing waste and energy use while maintaining product performance.

In summary, DDVP 1000EC 77.5% stands out as a fast-acting, versatile solution for pest control, supported by robust manufacturing capabilities that ensure quality and reliability. Its unique combination of contact, stomach, and fumigant action makes it indispensable in agriculture, public health, and stored-product protection.
