Chlorpyrifos 50% EC High Quality Agochemicals Pesticides Insecticides

What Is Chlorpyrifos and Why It Delivers Powerful Pest Control

Chlorpyrifos is an organophosphate insecticide with a multi-mode action: it works by contact, ingestion, and fumigation, making it highly effective against both above-ground and soil-dwelling insect pests. As a non-systemic insecticide, it stays on the surface of plant parts and soil to create a strong protective barrier, ensuring immediate and lasting control.

1. Triple Action for Fast and Extended Control

• Contact Action: Kills insects upon direct exposure to the spray

• Stomach Poison: Targets pests feeding on treated plant surfaces

• Fumigation Effect: Provides gaseous action in enclosed plant areas or soil

This combination ensures rapid knockdown and residual protection, even in challenging pest outbreaks.

2. Broad-Spectrum Activity

Chlorpyrifos controls a wide variety of agricultural pests, including:

• Lepidopteran larvae: Rice stem borers, armyworms, leaf rollers

• Homopterans: Aphids, whiteflies, planthoppers

• Coleopterans: Beetles, rootworms

• Soil pests: Cutworms, wireworms, grubs, termites

Its versatility makes it ideal for use across cereal crops, vegetables, oilseeds, and fruit trees.

3. High Compatibility and Tank-Mix Flexibility

• Compatible with most insecticides, fungicides, and foliar fertilizers

• Shows synergistic effects when mixed with pyrethroids like cypermethrin

• Often included in resistance management rotations to prevent pest adaptation

4. Reliable Field Performance in Diverse Conditions

Chlorpyrifos 50% EC performs well under:

• Tropical and subtropical climates

• High pest-pressure cropping systems

• Intensive agriculture with minimal crop phytotoxicity

Its proven effectiveness has made it a mainstay in integrated pest control programs across Asia, Africa, South America, and the Middle East.

• Avoid spraying sensitive crops like tobacco, tomato leaves, and melons

Chlorpyrifos can be applied up to 2–3 times per growing season, depending on label restrictions and local regulations.

Target Crops and Pest Control Spectrum – Versatile Across Agricultural Systems

Chlorpyrifos 50% EC is valued for its ability to control a wide range of both above-ground and soil-dwelling insect pests, offering comprehensive protection in cereal crops, industrial crops, vegetables, fruit trees, and ornamentals.

1. Suitable Crops

Chlorpyrifos is effective in the protection of:

• Cereals:

  • Rice

  • Wheat

  • Corn

• Industrial crops:

  • Cotton

  • Sugarcane

  • Tobacco (use with caution)

• Vegetables:

  • Tomato (avoid direct leaf spraying)

  • Onion

  • Cabbage

  • Eggplant

  • Root vegetables (carrot, beet)

• Orchard and fruit crops:

  • Citrus

  • Mango

  • Apple

  • Grape

• Flowers and ornamentals
  (except sensitive varieties like lettuce)

2. Major Pests Controlled

3. Notable Strength – Underground Pest Control

Chlorpyrifos can be applied as a root drench or soil spray, offering:

• Deep penetration and long residual in the rhizosphere

• More than 30 days of efficacy against grubs, cutworms, and borers

• Suitable for nursery and seedling protection

With such broad pest coverage, Chlorpyrifos remains a go-to solution for farmers in mixed cropping systems, multi-pest environments, and intensive production zones, giving distributors high-volume sales potential across different markets.

How Chlorpyrifos Works – Triple-Action Nerve Poison for Reliable Pest Knockdown

Chlorpyrifos is a non-systemic organophosphate insecticide that primarily functions by inhibiting acetylcholinesterase (AChE) in target pests. This inhibition leads to continuous nerve signal transmission, resulting in paralysis and death of the insect.

1. Acetylcholinesterase Inhibition – Fast Nerve System Disruption

• Chlorpyrifos binds irreversibly to AChE, an enzyme essential for nerve signal regulation.

• This causes excess acetylcholine to accumulate in the synaptic cleft.

• Insects lose muscle coordination, suffer spasms, and die within hours.

This action ensures rapid knockdown, even for pests in dense canopies or hard-to-reach areas.

2. Multi-Mode Delivery – Contact, Stomach, and Fumigation

Chlorpyrifos is effective via three exposure routes:

• Contact Poison: Kills insects upon physical contact with treated surfaces.

• Stomach Poison: Enters the insect’s digestive system when it feeds on treated crops.

• Fumigant Effect: Volatile activity creates toxic vapors in enclosed spaces (e.g., soil, plant canopy).

This makes Chlorpyrifos highly versatile, especially in multi-pest field conditions.

3. Non-Systemic Behavior – Surface-Level Action, Lower Residue Risk

• Chlorpyrifos does not move inside the plant; it remains on the surface, providing a protective layer.

• This reduces systemic residue risks and makes it suitable for crops with moderate residue requirements, especially when applied early.

4. Strategic Role in Resistance Management

• Chlorpyrifos has a different mode of action from neonicotinoids, pyrethroids, and diamides.

• Useful in rotation programs to combat resistance, especially for pests like:

  • Stem borers

  • Leafhoppers

  • Whiteflies

By alternating Chlorpyrifos with modern insecticides, growers can extend the lifespan of their pest control programs and delay resistance buildup.

Application Guidelines – Safe and Effective Use for Maximum Field Performance

Chlorpyrifos 50% EC is suitable for a variety of crops and pest scenarios. To ensure optimal efficacy while minimizing risk to crops, applicators, and the environment, follow these recommended application practices.

1. When to Apply

• At early pest appearance or before pest populations build up

• Ideal for preventive and curative spraying in pest-prone growth stages such as:

  • Tillering in rice

  • Pre-flowering in cotton

  • Early vegetative phase in vegetables

Repeat applications may be needed every 7–14 days, depending on infestation level and local conditions.

2. Dilution and Spray Volume

Always agitate the solution thoroughly during mixing and spraying to ensure uniform application.

3. Application Method

• Foliar spray:

  • Use backpack or tractor-mounted sprayers with fine nozzles for even canopy coverage

  • Apply during early morning or late afternoon to avoid evaporation and drift

• Soil treatment/root zone spray:

  • Apply diluted solution around plant bases to target underground pests (e.g., grubs, termites)

4. Re-Entry and Pre-Harvest Interval (PHI)

• Re-entry Interval (REI): Minimum 24 hours after spraying

• Pre-harvest Interval (PHI):

  • Rice/wheat: 14 days

  • Vegetables: 10–14 days

  • Fruits: 21 days (or as per local label)

5. Safety and Compatibility Notes

• Do not apply during strong wind or when rain is expected within 2 hours

• Avoid spraying sensitive crops like tobacco, tomato foliage, melons, and lettuce

• Wear full PPE: gloves, goggles, mask, long sleeves

• Do not mix with alkaline substances unless compatibility is confirmed

Properly applied, Chlorpyrifos offers robust, reliable protection with lasting residual effects, helping farmers minimize crop losses and reduce spray frequency.
