Product Overview

Bigul is a broad-spectrum, post-emergence herbicide developed by Indofil Industries Ltd. that provides effective control of a wide range of grassy and broadleaf weeds in various crops, including rice, sugarcane, and wheat. It contains two active ingredients:

1. Fluazifop p-butyl (11.1%)

2. Fomesafen (11.1%)

This combination of active ingredients provides comprehensive weed control, targeting both grassy and broadleaf weeds simultaneously.

Mode of Action

Bigul's herbicidal activity stems from its dual action mechanism:

1. Fluazifop p-butyl acts as an aryloxyphenoxy propionate (APP) herbicide, inhibiting acetyl-CoA carboxylase (ACCase), an enzyme essential for fatty acid biosynthesis in plants. By disrupting ACCase function, Fluazifop p-butyl prevents fatty acid synthesis, leading to impaired cell membrane integrity and ultimately causing weed death.

2. Fomesafen acts as a photosystem II inhibitor, disrupting the photosynthetic process in plants. By interfering with photosynthesis, Fomesafen prevents the production of essential energy molecules, leading to chlorosis, growth inhibition, and eventually death of the weeds.

Key Features and Benefits

Bigul offers several advantages that make it a popular choice for weed control in various crops:

1. Broad-spectrum efficacy: Effectively controls a wide range of grassy and broadleaf weeds, providing comprehensive weed management in rice, sugarcane, and wheat fields.

2. Fast action: Provides rapid knockdown of both grassy and broadleaf weeds, minimizing crop competition and promoting healthy crop growth.

3. Long-lasting residual protection: Offers long-lasting residual protection of up to 6 weeks, ensuring effective weed suppression and reducing the need for frequent re-application.

4. Low application rates: Effective at low application rates, reducing the environmental impact and minimizing residue levels in soil and water bodies.

5. Safe for target crops: Safe for use in various target crops without causing phytotoxicity, ensuring crop safety.

Application Guidelines

Bigul is typically applied as a foliar spray, ensuring thorough coverage of all weeds. The recommended dosage varies depending on the specific target weeds, weed density, and crop stage. Generally, a concentration of 1.5-3 liters/ha is recommended for rice, 2.5-3 liters/ha for sugarcane, and 1.5-2.5 liters/ha for wheat. Application timing should be during the active growth stage of the weeds, typically 2-3 weeks after transplanting or 3-4 weeks after germination for direct-sown rice.

Safety Precautions

Bigul is classified as moderately toxic, so it is essential to follow safety precautions during handling and application:

1. Personal Protective Equipment (PPE): Wear gloves, a mask, and overalls to minimize exposure to the product.

2. Avoid Direct Contact: Avoid direct contact with skin and eyes to prevent irritation.

3. Weather Conditions: Do not apply during hot or windy conditions to ensure proper dispersion and prevent drift.

4. Water Resources: Avoid applying near water bodies or waterways to prevent contamination.

5. Waste Disposal: Dispose of empty containers and unused products responsibly to protect the environment.

Overall, Bigul is a versatile and effective herbicide that provides broad-spectrum, fast-acting, long-lasting, and safe control of a wide range of grassy and broadleaf weeds in rice, sugarcane, and wheat cultivation. Its low application rates, compatibility with other crop protection chemicals, and suitability for both pre- and post-emergence application make it a valuable tool for integrated weed management (IWM) programs in various agricultural settings.

Here are some additional tips for using Bigul effectively:

1. Apply the spray evenly to all parts of the target weeds.

2. Do not apply the spray during hot weather or when the target crops are stressed.

3. Avoid applying the spray to wet crops.

4. Monitor the target crops for signs of phytotoxicity or weed resistance.

5. Rotate crops with non-grasses and non-broadleaf crops to prevent the development of weed resistance to Bigul.
