Sumitomo Dantotsu Insecticide – Clothianidin 50% WDG Systemic Control for Sucking Pests

Sumitomo Dantotsu is a broad-spectrum systemic insecticide formulated with Clothianidin 50% WDG (Water Dispersible Granules). It is designed to give farmers reliable, long-lasting control of sucking and soil-borne pests across five registered crops — paddy (rice), cotton, sugarcane, tea, and grapes. Dantotsu works from inside the plant: it is absorbed through the roots and foliage, then moves through the plant system to protect both existing leaves and new growth. This makes it highly effective against hidden pests that feed on the underside of leaves or live in dense canopies.

The product acts on the insect's nervous system by binding to acetylcholine receptors, which stops the pest from feeding, sucking, and laying eggs, leading to paralysis and death. Because it works at low doses, Dantotsu is a cost-effective choice for farmers. Its WDG formulation dissolves easily in water, mixes well in the spray tank, and stays effective even after rainfall. Classified as a Green Triangle product, Dantotsu is comparatively safer for the environment and beneficial soil organisms when used as per the CIB & RC recommendations, making it a practical option for integrated pest management (IPM).

Key Benefits

• Strong systemic and translaminar action protects both upper and lower leaf surfaces, reaching pests that hide from contact sprays.
• Long-lasting residual control of 14–21 days reduces the need for frequent sprays during the critical pest-pressure window.
• Low-dose efficiency — just 8–16 g per acre for foliar spray — makes it highly cost-effective for farmers.
• Rainfast formulation stays effective even after rainfall, giving farmers flexibility in application timing.
• Broad-spectrum action controls sucking pests (aphids, jassids, whitefly, thrips, mealybugs), hoppers (BPH, WBPH), and soil pests (termites, shoot borers).
• Selective action helps safeguard beneficial microorganisms in the soil.
• Easy-to-mix WDG granules dissolve quickly in water for hassle-free application.

How It Works

Dantotsu is a systemic neonicotinoid insecticide. When applied as a foliar spray or soil drench, the Clothianidin active ingredient is absorbed by the plant and translocated through its vascular system to all parts — including new growth. This means the protection travels within the plant itself, not just on the surface.

Inside the pest, Clothianidin acts as an agonist of the acetylcholine (ACh) receptors on the post-synaptic membrane of the insect's nervous system. This over-stimulates the nervous system, causing the pest to stop feeding, sucking, and laying eggs. The result is rapid paralysis and death. Because the product is taken in both orally and dermally, it works on pests that ingest treated plant tissue as well as those that come into direct contact with it. The translaminar activity ensures complete coverage of both leaf surfaces, while the systemic movement protects even the parts of the plant that were not directly sprayed.

Foliar spray dose: 8–16 g per acre (0.2–0.4 g per litre of water).
Drenching dose: 80–100 g per acre for most crops.

When to Use

• Apply at the first sign of pest infestation, before populations rise sharply, for maximum effectiveness.
• For paddy BPH, spray at the active tillering stage, typically 45–60 days after transplanting, directing the spray toward the base of the plant where hoppers cluster near the waterline.
• For cotton, apply soil drench within 7 days of germination for the most effective early-season sucking pest protection.
• For sugarcane, apply at the time of sowing to prevent termites and shoot borers.
• For grapes, apply through soil drenching around the root zone at the first sign of mealybug or thrips infestation.
• For tea, spray at the flowering stage to control Tea Mosquito Bug.
• Spray during early morning or late evening, avoiding peak bee foraging hours.
• Dantotsu provides 14–21 days of residual control. Repeat as needed up to 2–3 times per season, and rotate with products from different IRAC groups after 2 consecutive applications.

Step by Step Usage Instructions

1. Measure the required dose of Dantotsu as per the crop-wise dose table above.
2. Pre-dissolve the measured WDG granules in a small amount of clean water in a separate container first.
3. Add this mixture to the sprayer tank, then fill with the remaining clean water.
4. Agitate well to form a uniform solution before spraying.
5. For paddy BPH, direct the spray toward the base of the plant where hoppers cluster near the waterline — not just the upper leaves.
6. For cotton whitefly, ensure thorough coverage of the underside of leaves where nymphs concentrate.
7. For sugarcane and cotton soil drenching, dilute the required dose in 400 litres of water per acre and apply uniformly to the root zone within 7 days of germination or sowing.
8. For grapes, apply through soil drenching around the root zone at the first sign of mealybug or thrips infestation.
9. Spray during early morning or late evening, avoiding peak bee foraging hours.

Compatibility

Dantotsu is compatible with most commonly used insecticides, fungicides, and foliar fertilizers. However, always perform a jar test before mixing with unfamiliar inputs. Avoid mixing with strongly alkaline products.

Precautions & Safety

• Wear gloves and a face mask before handling or spraying Dantotsu.
• Do not eat, drink, or smoke during mixing or application.
• Avoid direct contact with skin and eyes — rinse immediately with clean water if contact occurs.
• Toxic to bees when wet — do not spray during active bee foraging hours, near beehives, or on flowering crops.
• Keep children, pets, and livestock away from treated fields for at least 12 hours.
• Wash all exposed skin with soap and water after every spray session.
• Triple rinse empty containers, puncture, and dispose of per local waste guidelines.
• Store in original sealed packaging in a cool, dry place away from direct sunlight and moisture.
• Keep away from food, animal feed, and seeds, and out of reach of children and farm animals.
