Dhanuka Dhanulux Quinalphos 25% EC Insecticide - Broad Spectrum Control for Cotton, Paddy, Soybean & Brinjal

Dhanuka Dhanulux is a broad-spectrum organophosphate insecticide containing Quinalphos 25% EC (emulsifiable concentrate). It is designed to protect major crops from a wide range of chewing and sucking insect pests, including mites. Dhanulux works through both contact and stomach action, which means pests are controlled either by direct contact with the spray or by ingesting treated plant material. This dual mode of action makes it a dependable and versatile choice for farmers managing pest pressure across cotton, paddy, soybean, and brinjal.

The product offers good initial knockdown and strong residual activity, giving crops prolonged protection after each application. It is effective against bollworms on cotton, and stem borer, leaf folder, green leafhopper, and hispa on rice. On soybean it helps control stem borer, girdle beetle, and leaf miner, while on brinjal it targets shoot and fruit borer. Dhanulux is non-phytotoxic to crops when used at the recommended dosages, and it is compatible with most commonly used pesticides except those of an alkaline nature.

Available in pack sizes of 100 ml, 250 ml, 500 ml, 1 litre, 5 litre, and 20 litre, Dhanulux is a practical, cost-effective solution for integrated pest management. Its broad-spectrum activity, ease of foliar application, and reliable residual control make it a trusted choice for farmers looking to protect their yields from damaging insect populations.

Key Benefits

• Dual contact and stomach action ensures pests are controlled on direct contact or after feeding on treated plant parts.
• Good initial and residual toxicity provides prolonged protection, reducing the need for frequent sprays.
• Effective against major pests including bollworms, stem borer, leaf folder, green leafhopper, hispa, girdle beetle, leaf miner, and shoot and fruit borer.
• Non-phytotoxic to recommended crops when applied at specified dosages, protecting crop health.
• Compatible with most commonly used pesticides, allowing flexible tank-mix planning (except alkaline products).
• Available in multiple pack sizes to suit small and large farms.

How It Works

Dhanulux contains Quinalphos 25% EC, an organophosphate insecticide that acts as both a contact and stomach poison. When the spray comes into direct contact with the pest, the chemical is absorbed through the insect's body and disrupts its nervous system, leading to rapid knockdown. Pests that feed on treated leaves, stems, or other plant parts also ingest the chemical, which acts as a stomach poison and kills them after feeding.

This dual mode of action makes Dhanulux effective against a wide range of insects, including chewing pests like bollworms and stem borers, and sucking pests like green leafhopper and aphids. The emulsifiable concentrate formulation spreads evenly on the leaf surface and provides good residual activity, meaning the protective effect continues for a period after application. This combination of quick action and lasting residual control helps farmers manage pest populations effectively and protect crop yields.

Technical Specifications

Recommended Dosage & Application

Dhanulux is applied as a foliar spray with thorough coverage of the crop canopy. The recommended dosage varies by crop. Mix the required quantity with 500–1000 litres of water per hectare, depending on crop and pest severity.

Dilute the measured quantity in the recommended volume of water and spray evenly over the crop, ensuring good coverage of all plant parts, especially where pests are active.

When to Use

Apply Dhanulux at the onset of pest infestation or as per monitoring thresholds. Early application, when pest populations are just beginning to build up, gives the best control and prevents damage from spreading. For chewing pests like bollworms and stem borers, apply when larvae are young and actively feeding. For sucking pests like green leafhopper and aphids, apply as soon as their presence is noticed on the crop.

Regular scouting of the field helps farmers decide the right time to spray. Avoid spraying during heavy rainfall or strong winds, as this can reduce the effectiveness of the product and cause drift. For best results, ensure the crop canopy is dry at the time of spraying and that the spray covers the undersides of leaves where many pests hide.

Step by Step Usage Instructions

1. Wear protective clothing, gloves, mask, and goggles before handling the product.
2. Measure the recommended dosage for your crop (refer to the dosage table above).
3. Fill the spray tank with a small amount of clean water.
4. Add the measured quantity of Dhanulux to the tank and mix well.
5. Add the remaining water to reach the recommended volume (500–1000 litres per hectare).
6. Stir the mixture thoroughly to ensure a uniform spray solution.
7. Spray evenly over the crop, ensuring thorough coverage of leaves, stems, and affected plant parts.
8. Clean all spraying equipment thoroughly after use.
9. Wash hands and exposed skin with soap and water after application.
