Product Overview

Passport is a post-emergence selective herbicide developed by Indofil Industries Ltd. that provides effective control of a wide range of broadleaf weeds, including pigweed, nightshade, and morning glory, in various crops, such as soybeans, corn, and cotton. It contains Imazethapyr 10% SL as its active ingredient, a group 2 imidazolinone herbicide that inhibits the enzyme acetohydroxy acid synthase (AHAS), an essential component of the branched-chain amino acid (BCAA) biosynthesis pathway in plants.

Mode of Action

Passport's herbicidal activity stems from its interference with AHAS, which prevents the formation of BCAAs, essential building blocks of proteins and other plant molecules. By disrupting BCAA synthesis, Passport disrupts protein synthesis, enzyme production, and other vital cellular processes, leading to stunted growth, chlorosis, and ultimately death of the target weeds.

Key Features and Benefits

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

1. Broad-spectrum efficacy: Effectively controls a wide range of broadleaf weeds, including pigweed, nightshade, and morning glory, providing comprehensive weed management in soybeans, corn, and cotton fields.

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

3. Systemic action: Provides systemic control of both exposed and concealed weeds, ensuring effective weed suppression even in dense crop canopies.

4. Quick knockdown and long-lasting residual protection: Offers rapid knockdown of weeds and long-lasting residual protection of up to 6 weeks, minimizing crop competition and promoting healthy crop growth.

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

Application Guidelines

Passport is typically applied as a foliar spray, ensuring thorough coverage of all target weeds. The recommended dosage varies depending on the specific target weeds, weed density, crop stage, and soil type. Generally, a concentration of 100-200 g/ha is recommended for soybeans, 100-150 g/ha for corn, and 150-200 g/ha for cotton. Application timing should be during the active growth stage of the weeds, typically 2-3 weeks after planting for soybeans and corn, and 3-4 weeks after emergence for cotton.

Safety Precautions

Passport 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, Passport is a versatile and effective herbicide that provides broad-spectrum, selective, systemic, quick knockdown, and long-lasting control of a wide range of broadleaf weeds in soybeans, corn, and cotton. 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 Passport 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-broadleaf crops to prevent the development of weed resistance to Passport.
