Chlorpyriphos 50% + Cypermethrin 5% EC

Chlorpyrifos 50% + Cypermethrin 5% EC is a insecticide widely used in agriculture. It combines two different chemical classes to provide both immediate "knockdown" and long-lasting protection.

## How It Works (Mode of Action)

This combination is highly effective because it attacks the insect's nervous system in two different ways:

• Chlorpyrifos (50%): An organophosphate that acts as a stomach and respiratory poison. It inhibits the enzyme acetylcholinesterase, causing the insect's nervous system to fail. It also has a "vapor action" that helps reach pests hidden in dense foliage.

• Cypermethrin (5%): A synthetic pyrethroid that provides quick knockdown via contact. It disrupts sodium channels in the nerve cells, leading to instant paralysis.

### Target Crops & Pests

It is primarily used for crops that suffer from a mix of sucking and chewing pests.

### Recommended Dosage

Note: Always follow the specific instructions on the product label as they can vary by brand and local regulations.

• General Dosage: 3040 ml per 15-liter spray pump.

• Per Acre: Approximately 400500 ml diluted in 200 liters of water.

• Waiting Period: Usually 1015 days must pass between the last spray and harvesting the crop.

### Key Benefits

1. Synergistic Effect: The two chemicals work better together than they do separately, making it effective against pests that might be resistant to single-ingredient sprays.

2. Translaminar Action: It can penetrate the leaf surface to kill larvae hiding on the underside or inside the plant tissue.

3. Economical: Because it controls multiple types of pests at once, it reduces the need for multiple different sprays.

Safety & Precautions

• Protective Gear: Always wear gloves, a face mask, and goggles. Avoid inhaling the spray mist.

• Honeybees & Fish: This product is highly toxic to bees (do not spray during flowering/foraging) and aquatic life. Avoid spraying near water bodies.

• Storage: Keep in a cool, dry place, strictly away from food, children, and livestock.
