IIL Torry Super Herbicide - Tembotrione 9% + Atrazine 45% WG for Maize Weed Control

IIL Torry Super is a post-emergence herbicide specially developed for maize crops, combining two powerful active ingredients — Tembotrione 9% and Atrazine 45% in a WG (Water Dispersible Granule) formulation. This product is designed to tackle a wide spectrum of broadleaf and grassy weeds that compete with maize for nutrients, water, and sunlight. Manufactured by Insecticides (India) Limited (IIL), Torry Super is built on the company's proprietary SPF Technology, which enhances the herbicide's effectiveness while improving crop tolerance to herbicidal stress.

What makes Torry Super stand out is its speed of action. Farmers can see visible weed control results within just 3 to 5 days of application. Additionally, it offers extended residual activity for up to 15 days beyond conventional herbicides, meaning fields stay weed-free for longer. This reduces the need for repeated sprays and saves both time and labour. The product was officially launched on 5th October 2024 for the Indian domestic market and is already being positioned as a leading maize herbicide solution.

Torry Super is recommended for use at a dosage of 500-600 grams per acre, mixed with a surfactant at 2 ml per litre of water for best results. It is a post-emergence herbicide, meaning it is applied after the weeds have emerged and the crop is already growing. This makes it a practical and effective choice for maize farmers looking for reliable, long-lasting weed management. Please note that this product is restricted in the state of Kerala.

Key Benefits

• Fast visible results: Weeds start showing signs of control within 3 to 5 days of spraying, giving farmers quick confirmation of effectiveness.
• Long-lasting protection: Provides residual weed control for up to 15 days beyond conventional herbicides, reducing the need for repeat applications.
• Dual-action weed control: Combination of Tembotrione and Atrazine targets both broadleaf and grassy weeds commonly found in maize fields.
• SPF Technology for crop safety: Unique technology developed by IIL's R&D team enhances the maize crop's tolerance to the herbicide, minimising stress on the plant.
• Reduces weed competition: Effective control means weeds do not compete with maize for nutrients, water, and sunlight, leading to healthier crop growth.
• Saves time and labour: Longer residual activity and fewer sprays mean less time spent in the field on weed management.
• Easy to apply: WG (Water Dispersible Granule) formulation mixes easily in water and is convenient for standard spraying equipment.

How It Works

IIL Torry Super works through the combined action of two active ingredients — Tembotrione and Atrazine — that attack weeds through different mechanisms. Tembotrione belongs to the triketone chemical group and works by inhibiting the HPPD enzyme in susceptible weeds. This enzyme is essential for the production of carotenoids, which protect the plant's chlorophyll from sunlight damage. When this process is blocked, the weed's leaves turn white (bleaching effect) and the plant eventually dies. Atrazine, on the other hand, belongs to the triazine group and works by inhibiting photosynthesis at the photosystem II level, stopping the weed from converting sunlight into energy. Together, these two active ingredients provide a powerful, multi-site attack on weeds, making it difficult for them to develop resistance. The herbicide is absorbed by weed foliage and roots, and moves systemically within the weed to ensure complete control. The SPF Technology in Torry Super enhances the maize crop's natural ability to metabolise the herbicide, meaning the crop remains safe while the weeds are effectively eliminated. This selective action is what makes Torry Super a reliable post-emergence solution for maize.

Recommended Dosage & Application

Crop	Dosage	Surfactant	Water Volume	Application Method
Maize	500 to 600 grams per acre	2 ml per litre of water	As per standard spray volume (typically 200-250 litres per acre)	Post-emergence foliar spray

Important: Use a non-ionic surfactant or recommended adjuvant at 2 ml per litre of water to improve weed coverage and herbicide uptake. Apply when weeds are young and actively growing for best results.

When to Use

Torry Super is a post-emergence herbicide, meaning it should be applied after the weeds have emerged and are in their early growth stage (2 to 4 leaf stage for most weeds). The ideal time for application is when the maize crop is at 3 to 6 leaf stage, as this is when weeds are most vulnerable and the crop can tolerate the herbicide well. Apply when soil moisture is adequate and weather conditions are favourable — avoid spraying during heavy rain, extreme heat, or when the crop is under moisture stress. Early application ensures that weeds are small and have not yet established strong competition with the maize crop. For best results, apply within 15 to 20 days after sowing of maize, depending on weed emergence patterns.

Step by Step Usage Instructions

1. Calculate the required quantity: Measure 500 to 600 grams of IIL Torry Super for each acre of maize field.
2. Prepare the spray mixture: Fill the spray tank with half the required volume of clean water. Add the measured Torry Super granules while stirring continuously until fully dissolved.
3. Add surfactant: Add a non-ionic surfactant at 2 ml per litre of water to the tank mixture. Stir well.
4. Top up with water: Add the remaining water to reach the desired spray volume (typically 200-250 litres per acre for knapsack sprayers).
5. Spray evenly: Apply the mixture as a uniform foliar spray over the weeds and crop. Ensure good coverage of weed foliage.
6. Clean equipment: After spraying, thoroughly clean all spray equipment with water to avoid residue buildup.
7. Monitor results: Check the field after 3 to 5 days for visible weed control. Residual protection continues for up to 15 days beyond conventional herbicides.

Precautions & Safety

• Wear protective gloves, mask, and goggles while handling and spraying the herbicide.
• Avoid inhalation of dust or spray mist during mixing and application.
• Do not eat, drink, or smoke while handling the product.
• Wash hands and exposed skin thoroughly with soap and water after use.
• Store the product in a cool, dry place away from food, animal feed, and children.
• Avoid spray drift to neighbouring crops, water bodies, and non-target areas.
• Do not apply near water sources or during windy conditions to prevent drift.
• This product is restricted in Kerala State — do not use or sell in Kerala.

Side Effects & Phytotoxicity

The SPF Technology in Torry Super is specifically designed to enhance crop tolerance and minimise herbicidal stress on maize. However, as with any herbicide, improper dosage or application under unfavourable conditions (such as extreme heat, waterlogging, or drought stress) may cause temporary crop yellowing or growth suppression. Always follow the recommended dosage and application guidelines to avoid any adverse effects on the crop.
