Diafenthiuron 47.8% SC
Diafenthiuron 47.8% SC is a broad-spectrum, non-systemic insecticide and acaricide from the thiocarbamate chemical group — specifically classified under Group 12A mode of action. Trusted by cotton and vegetable farmers across India, it delivers fast, reliable control of the most damaging sucking pests and mites, especially in situations where older insecticide classes have started to lose effectiveness due to resistance build-up in pest populations.
How Diafenthiuron 47.8% SC Works
Unlike most conventional insecticides that target the nervous system of pests, Diafenthiuron 47.8% SC works through a completely different and unique biological pathway. It acts as a mitochondrial electron transport inhibitor — blocking the production of ATP (Adenosine Triphosphate), which is the primary energy currency that every living cell depends on to function. When this energy production is disrupted, the pest’s cells can no longer carry out normal biological activities, leading to rapid paralysis and death. This mechanism is completely different from organophosphates, pyrethroids, and neonicotinoids, which is why it remains highly effective against pests that have already developed resistance to those chemistries.
Why Farmers Choose This Insecticide
One of the most valued features of Diafenthiuron 47.8% SC is its triple-mode delivery — working through contact, stomach action, and translaminar penetration simultaneously. Contact action kills pests on direct touch with the spray, stomach action controls those that ingest treated plant material, and translaminar activity allows the active ingredient to penetrate the leaf surface and reach pests hiding on the underside of leaves — giving more complete pest control than surface-only sprays can provide.
This product is particularly effective against phytophagous mites alongside sucking insect pests, making it a dual insecticide-acaricide in one bottle. Farmers dealing with simultaneous mite and whitefly or thrips pressure — a very common situation in cotton and chilli crops — find this combination especially valuable for simplifying their spray schedule and getting two pest problems under control with a single application. The Suspension Concentrate (SC) formulation ensures easy mixing, stable suspension in the spray tank, and uniform distribution across the crop canopy.
Key Benefits
- Controls aphids, whiteflies, thrips, jassids, and phytophagous mites
- Triple action — contact, stomach, and translaminar activity together
- Unique Group 12A mode of action — effective against resistant pest populations
- Dual insecticide and acaricide — handles mites and sucking insects together
- Quick knockdown with long-lasting residual protection
- Easy to mix SC formulation — uniform spray distribution
- Compatible with most commonly used insecticides and fungicides
Why Crop Nutrition Matters Alongside Pest Control
Crops recovering from sucking pest and mite pressure grow best when also given strong nutritional support throughout the season. Products like Humic Acid 98% Flakes help build a stronger root system to support faster recovery after pest stress, 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
- Shake the container well before measuring the required dose
- Mix the required quantity in a small amount of water first, then add to the sprayer tank and fill with the remaining water
- Apply at the first sign of pest infestation — do not wait for heavy build-up
- Use in rotation with other insecticide groups to avoid resistance development
- Wear gloves, mask, and protective clothing while mixing and spraying
- Avoid direct contact with skin and eyes during application
- Avoid mixing with strongly acidic or alkaline substances
- Maintain the recommended pre-harvest interval before harvesting for market
- Wash hands and exposed skin thoroughly with soap after spraying
- Keep away from children, animals, and food or feed storage areas
Storage Instructions
