IIL Supremo SP Insecticide - Thiocyclam Hydrogen Oxalate 50% SP for Paddy & Vegetables

IIL Supremo SP is a broad-spectrum insecticide from Insecticides (India) Limited, containing Thiocyclam Hydrogen Oxalate 50% in a soluble powder (SP) formulation. This insecticide is designed to effectively control a wide range of chewing and sucking insect pests in paddy (rice) and vegetable crops. It works through both contact and systemic action, meaning it kills pests on direct contact and also gets absorbed by the plant to provide protection from within.

Thiocyclam Hydrogen Oxalate has a unique mode of action. At low concentrations, it shows cholinergic effects, and at high concentrations, it acts as an antagonist, blocking cholinergic transmission in the insect's nervous system. This leads to paralysis and eventually death of the pest. Importantly, it does this without affecting the cholinesterase enzyme activity, making it distinct from many conventional insecticides.

IIL Supremo SP is particularly effective against stem borer and leaf folder in paddy, and provides reliable control against caterpillars, beetles, aphids, leafhoppers, and whiteflies in vegetables. It offers prolonged residual activity, reducing the need for frequent sprays. The product is classified under the Blue Triangle toxicity category, indicating it is moderately toxic and requires careful handling as per label instructions.

Key Benefits

• Provides effective control against both chewing pests (caterpillars, beetles) and sucking pests (aphids, leafhoppers, whiteflies) in a single product
• Works through both contact and systemic action, protecting sprayed and unsprayed plant parts
• Offers prolonged residual activity, reducing the number of sprays needed per season
• Unique mode of action helps in managing insecticide resistance when used as part of a rotation program
• Acts as a stomach poison too, killing pests that feed on treated plant tissue
• Soluble powder formulation mixes easily in water and is convenient for foliar spray application

How It Works

IIL Supremo SP contains Thiocyclam Hydrogen Oxalate, which acts on the nervous system of insects in a unique two-way manner. At low concentrations, it stimulates cholinergic activity, and at higher concentrations, it blocks cholinergic transmission. This blocking action prevents nerve signals from passing through, causing the insect to become paralysed and eventually die. Importantly, this insecticide does not inhibit the cholinesterase enzyme, which is the target site for many organophosphate and carbamate insecticides. This makes it a valuable tool for resistance management.

As a systemic insecticide, Thiocyclam Hydrogen Oxalate is absorbed by the plant and moves through the plant tissues, providing protection to new growth and parts that are not directly sprayed. As a contact insecticide, it kills pests when they come in direct contact with the spray droplets. Additionally, it acts as a stomach poison, meaning when insects feed on treated plant parts, they ingest the chemical and die. This triple action—contact, systemic, and stomach poison—makes Supremo SP highly effective against a wide range of pests.

When to Use

Apply IIL Supremo SP when pest infestation is first noticed or when pest populations reach the economic threshold level. For paddy, apply at the early stages of stem borer or leaf folder infestation. Early application gives the best results as the product works effectively on young larvae and nymphs. Monitor the crop regularly and spray when pest activity is observed. For best results, apply during cooler parts of the day—early morning or late evening—when pests are more active and the spray droplets dry slowly, allowing better absorption.

Step by Step Usage Instructions

1. Calculate the dose: Measure the required quantity of IIL Supremo SP based on your crop and pest. For paddy, use 400-450 gm per acre.
2. Prepare the spray solution: Fill the spray tank with half the required amount of clean water. Add the measured quantity of Supremo SP while stirring continuously.
3. Mix thoroughly: Stir well until the powder dissolves completely. Add the remaining water and mix again.
4. Spray evenly: Apply the solution as a fine foliar spray, covering all parts of the plant including the underside of leaves where pests often hide.
5. Clean equipment: After spraying, thoroughly clean all spray equipment with clean water. Do not dispose of leftover spray solution or wash water into water bodies.

Precautions & Safety

• Wear protective clothing including gloves, mask, and goggles while handling and spraying the product
• Avoid inhalation of the powder or spray mist
• Do not eat, drink, or smoke while handling or spraying
• Wash hands and face thoroughly with soap and water after spraying
• Store in a cool, dry place away from food, feed, and children
• Keep away from water bodies to avoid contamination
• Do not use empty containers for storing food or water

Side Effects & Phytotoxicity

When used as per recommended dosage and application method, IIL Supremo SP is safe for the target crops. However, as with any chemical insecticide, avoid over-application or spraying under extreme weather conditions. Do not spray during heavy rainfall or when rain is expected within a few hours, as it may wash off the chemical. Always follow the recommended dosage—do not exceed the specified rate.

PHI / REI & Storage

• Storage: Store in a cool, dry place away from direct sunlight and moisture. Keep the container tightly sealed when not in use.
• Shelf Life: 2 years from the date of manufacture when stored under proper conditions.
