Fomesafen 

CAS  NO: 72178-02-0Attribute: Selective pre-emergence herbicideCharacteristic: Through the absorption of weed stems and leaves and through limited conduction, it features rapid effect, wide spectrum of control, and high safety.

Product Overview


Fomesafen is a highly effective, selective, and reliable pre-emergence and post-emergence herbicide, specifically engineered to optimize crop protection in leguminous fields. With its CAS registry number 72178-02-0, Fomesafen has become a staple solution in modern agricultural practices, particularly for maximizing the yield potential of soybeans and peanuts.

Product Overview and Mechanism of Action

Fomesafen operates primarily through the absorption by weed stems and leaves, providing a robust defense mechanism against invasive broad-leaved weeds. Its mechanism of action involves the inhibition of the protoporphyrinogen oxidase (PPO) enzyme, which is critical for chlorophyll biosynthesis in plants. Once absorbed, Fomesafen displays limited conduction within the weed, ensuring that its herbicidal activity is focused on eliminating competition for essential nutrients, light, and water.

This herbicide is recognized for its rapid effect and wide spectrum of control. By effectively disrupting the growth of targeted weed species, Fomesafen ensures that crops can thrive without the detrimental impact of nutrient-stealing competitors. Furthermore, its high safety profile when used according to recommended guidelines makes it a preferred choice for sustainable integrated pest management (IPM) programs.

Usage Guidelines and Safety Precautions

To achieve the best results and ensure maximum safety for crops and the environment, strictly follow these guidelines:

  • Dosage Control: It is critical to precisely control the dosage of Fomesafen. Over-application can result in residual toxicity, which may cause harm to sensitive crops planted in the subsequent season. Always perform soil and field assessments before application.

  • Safety Interval: Respect the mandatory safety interval period for agricultural products. Do not harvest or consume crops until the safety interval has completely elapsed to ensure residue levels comply with safety standards.

  • Application Timing: For optimal results, application should be timed correctly based on the growth stage of both the target weeds and the protected crops.

Frequently Asked Questions (FAQ)

1. Can Fomesafen be used on crops other than legumes?

Fomesafen is highly selective and primarily designed for legumes like soybeans and peanuts. Its use on non-target, sensitive broad-leaved crops is generally discouraged due to the risk of phytotoxicity.

2. What is the significance of the "limited conduction" mentioned?

The limited conduction means the herbicide stays largely where it is absorbed on the weed, reducing the potential for systemic movement that could inadvertently damage the protected crop, thus enhancing its safety profile.

3. How do you support the registration process in our country?

We provide full technical support, including GLP data, ICAMA documentation, and Letters of Access (LOA) to assist you in securing local product registration.

  • How does Fomesafen's mode of action work?

    How does Fomesafen's mode of action work?

    As a PPO inhibitor (Group 14), Fomesafen disrupts cell membranes, causing rapid desiccation of weed foliage. Visible symptoms (wilting, necrosis) typically appear within 24-72 hours after application, with complete control achieved within 7-14 days depending on environmental conditions.

  • How does rainfall affect Fomesafen performance?

    How does rainfall affect Fomesafen performance?

    Rainfall within 4-6 hours after application may reduce foliar efficacy. However, subsequent rainfall helps incorporate the herbicide into the soil, enhancing its residual activity against later-emerging weeds.

  • What rotational restrictions apply after Fomesafen use?

    What rotational restrictions apply after Fomesafen use?

    Due to persistence, avoid planting small grains, alfalfa, or vegetables for 4-12 months after application. Corn and soybeans are generally safe for rotation. The exact waiting period depends on application rate and soil conditions.

  • What precautions minimize crop injury risks?

    What precautions minimize crop injury risks?

    Use recommended rates and avoid overlapping spray passes. Soybean varieties differ in tolerance - conduct small-scale trials with new cultivars before full-field applications. Applications should be made when crops are not under stress from drought or extreme temperatures.
