Chlorpyriphos 50% + Cypermethrin 5% EC

Chlorpyriphos Cypermethrin EC

Chlorpyriphos 50% + Cypermethrin 5% EC is one of India’s most trusted and widely used dual-action insecticides, combining the deep residual power of Chlorpyriphos with the instant knockdown speed of Cypermethrin in a single, ready-to-use emulsifiable concentrate. Widely recommended by agricultural experts as a “rescue” insecticide for situations where a single product has failed to control a mixed pest attack, it offers farmers a powerful and economical solution when both chewing and sucking pests are present in the field at the same time.

How Chlorpyriphos Cypermethrin EC Works

This insecticide works through three complementary modes of action simultaneously — contact, stomach, and vapor action. Cypermethrin provides instant knockdown by disrupting sodium channels in the insect’s nervous system the moment a pest touches the treated surface, causing immediate paralysis. Chlorpyriphos acts more deeply — it inhibits the enzyme acetylcholinesterase, which is essential for normal nerve signal termination, causing continuous nerve excitation and eventual death. Its vapor action is particularly valuable for controlling hidden pests like stem borers and leaf folders that shelter inside folded leaves or within plant stems, where direct spray contact is impossible.

Why Farmers Choose This Insecticide

One of the most valued strengths of Chlorpyriphos Cypermethrin EC is its ability to penetrate the thick, waxy cuticle of mature, voracious-feeding larvae — a challenge that many other insecticides struggle with when pest populations have already grown beyond early infestation stage. This deep penetrability makes it particularly effective when farmers are dealing with a rescue situation where pest numbers are already high and quick, strong action is urgently needed to prevent further crop damage.

Its higher persistence on the leaf surface also gives it long-lasting residual protection — meaning the crop continues to be protected for an extended period after a single spray, even with moderate rainfall, reducing how often repeat applications are needed during peak pest pressure seasons. Being compatible with most commonly used fungicides and insecticides, it integrates easily into existing crop protection programs without requiring significant changes to the spray schedule.

Key Benefits

• Controls bollworms, stem borers, leaf miners, caterpillars, and termites
• Also effective against aphids, jassids, thrips, and whiteflies
• Triple action — contact, stomach poison, and vapor activity together
• Instant knockdown from Cypermethrin combined with long residual from Chlorpyriphos
• Penetrates thick larval cuticle — effective even against mature, hard-to-kill larvae
• Long persistence on leaf surface for extended field protection
• Economical combination product — cost-effective for large-scale farming

Why Crop Nutrition Matters Alongside Pest Control

Crops recovering from heavy pest attack grow best when also supported with proper nutrition to restore healthy growth. Products like Humic Acid 98% Flakes help build a stronger root system to support faster crop recovery, while Power PGR Liquid helps the plant channel its renewed energy into better flowering and fruit setting through the rest of the season.

Safety Tips & Precautions

• Pour the required dose into a bucket of water, stir well to form a uniform emulsion, then add to the spray tank
• Use a hollow cone nozzle and ensure thorough coverage of both upper and lower leaf surfaces and stems
• Toxic to bees — do not spray during flowering or when bees are actively foraging; spray only in the late evening
• Highly toxic to fish — never spray near ponds, rivers, or other water bodies
• Wear gloves, mask, goggles, and full-sleeve protective clothing during application
• Maintain a pre-harvest interval of at least 15 days before harvesting for market
• Do not mix with alkaline compounds — always check compatibility before tank mixing
• Wash hands and exposed skin thoroughly with soap after spraying
• Keep away from children, animals, and food or feed storage areas

Storage Instructions
