Vadh CS - Lambda-Cyhalothrin 4.9% CS - HPM

HPM Vadh CS Product Overview

HPM Vadh CS is a capsule-suspension insecticide containing lambda-cyhalothrin 4.9% CS. It is registered for labelled insect pests in cotton, paddy, brinjal, okra, tomato, grapes and chilli.

Lambda-cyhalothrin is a non-systemic synthetic pyrethroid with contact and stomach action. The capsule-suspension formulation holds the active ingredient in small capsules dispersed in water and releases it after the spray deposit dries on the crop and target pest. Always use this product only on the crops, pests and doses printed on the current pack label.

Key Benefits of Vadh CS

• Contact and stomach action: controls labelled insects when they contact treated surfaces or feed on treated plant material.
• Rapid knockdown: the manufacturer describes lambda-cyhalothrin as providing quick pest knockdown with residual activity.
• Capsule suspension: the CS formulation releases the active ingredient after the spray deposit dries.
• Multi-crop label: includes important borer, leaf-folder, thrips and flea-beetle uses across the listed crops.
• Resistance-group clarity: IRAC Group 3A identification supports rotation planning with insecticides from different mode-of-action groups.

Technical Specifications

How It Works

Lambda-cyhalothrin acts on insect nerve sodium channels and is classified by IRAC in Group 3A. Contact with the treated surface or ingestion of treated plant material disrupts normal nerve function, leading to knockdown. For resistance management, do not rely repeatedly on Group 3A products; follow the label and local expert guidance when rotating modes of action.

Labelled Crops, Pests, Dose and PHI

Use the crop-specific dose. The following per-acre figures are stated by HPM and align with the registered formulation recommendations. PHI is the minimum interval between the last spray and harvest.

Application and Safety

• Apply at pest initiation or the economic-threshold stage and follow the current pack label for timing and repeat sprays.
• Measure the crop-specific dose, add it to a partly filled spray tank, agitate, then add the remaining water for uniform coverage.
• Do not enter treated areas for 48 hours after spraying, as stated on the registered label.
• Wear protective clothing, gloves, eye protection and a mask; avoid inhalation and skin or eye contact.
• Lambda-cyhalothrin is highly hazardous to fish and bees. Prevent spray drift and contamination of water bodies, feed and food.

Frequently Asked Questions

What does 4.9% CS mean?
It means the product contains 4.9% w/w lambda-cyhalothrin in a capsule-suspension formulation.

Can Vadh CS be used on any crop?
No. Use it only on crops and target pests listed on the current product label.

When should it be sprayed?
The registered guidance starts treatment at pest initiation or the economic-threshold stage. Follow local monitoring and the pack label.

Can it be tank-mixed?
HPM reports compatibility with most insecticides, but compatibility is not the same as an approved recommendation. Check both labels and obtain local expert advice before mixing.

How should Group 3A resistance be managed?
Avoid treating successive pest generations only with Group 3A insecticides. Rotate to a registered product from a different IRAC group when appropriate and follow local advice.
