Imazapic 240g/L SL Herbicide – Selective Crop Protection for Peanut and Sugarcane

Introduction to Imazapic Herbicide

Imazapic is a selective, systemic herbicide belonging to the imidazolinone chemical family. It is used in agricultural vegetation management programs to control or suppress a range of annual grasses, broadleaf species, and sedges.

Its systemic activity and ability to inhibit plant growth make it an important active ingredient in selected crop protection programs.

Imazapic is especially relevant to peanut production, where effective management of competing vegetation is essential for healthy crop establishment and development. Applications in other crops, including sugarcane, depend on national registrations, crop tolerance, and individual product labels.

For agricultural importers, distributors, and formulation companies, Imazapic is available in different product forms, including soluble concentrate formulations and technical-grade material.

What Is Imazapic?

Imazapic is an imidazolinone herbicide with the chemical name 5-methyl-2-(4-methyl-5-oxo-4-propan-2-yl-1H-imidazol-2-yl)pyridine-3-carboxylic acid.

Its CAS number is 104098-48-8, and its molecular formula is C14H17N3O3.

The active ingredient is classified as an acetolactate synthase (ALS) inhibitor, also known as an an acetohydroxyacid synthase (AHAS) inhibitor.

This mode of action interferes with the production of essential branched-chain amino acids required for plant development.

By disrupting these biochemical processes, Imazapic prevents susceptible plants from maintaining normal growth.

Mode of Action

Imazapic belongs to Herbicide Group 2 under the international mode-of-action classification system.

Its primary mechanism involves inhibition of the ALS/AHAS enzyme.

This enzyme is necessary for the biosynthesis of three important amino acids:

• Valine
• Leucine
• Isoleucine

When susceptible plants absorb Imazapic, amino acid production is disrupted, causing growth to slow or stop.

Visible symptoms may develop gradually, including chlorosis, stunting, discoloration, and eventual plant death.

Unlike fast-acting contact herbicides, Imazapic works through physiological processes within the plant.

It can be absorbed through foliage and roots and transported toward active growing tissues.

The rate and extent of activity depend on environmental conditions, plant species, growth stage, and application method.

Imazapic for Peanut Crop Protection

Peanut is one of the important agricultural crops associated with Imazapic use.

During early growth, peanut plants can face competition from grasses, broadleaf vegetation, and sedges.

Uncontrolled competition may interfere with access to nutrients, moisture, light, and growing space.

Imazapic can help manage susceptible vegetation in peanut fields when applied according to a locally approved product label.

Potential Benefits in Peanut Production

Systemic Activity

Imazapic is absorbed by plant foliage and roots, allowing the active ingredient to affect susceptible growing tissues.

Activity Against Multiple Vegetation Types

The active ingredient has activity against certain annual grasses, broadleaf species, and sedges.

Residual Activity

Imazapic can provide soil residual activity, depending on application conditions and soil characteristics.

Integration into Crop Management Programs

Where registered, Imazapic can be incorporated into a broader crop protection strategy involving field monitoring, crop rotation planning, and resistance management.

For effective results, growers must follow the approved application timing, dosage, crop restrictions, and rotational crop intervals.

Imazapic in Sugarcane Production

Sugarcane is a major commercial crop in tropical and subtropical agricultural regions.

Competition from unwanted vegetation can create challenges during crop establishment and early development.

Imazapic may be relevant to sugarcane management programs in markets where specific formulations and applications are officially registered.

However, crop tolerance and permitted use patterns differ between countries.

Agricultural distributors should verify local registrations before promoting Imazapic for sugarcane.

Target Vegetation

Imazapic may provide control or suppression of selected vegetation categories, including:

Annual Grasses

Certain annual grass species are susceptible to ALS-inhibiting herbicides, particularly during early development.

Broadleaf Species

Imazapic can provide activity against selected broadleaf species, although susceptibility varies.

Sedges

Certain sedge species, including some nutsedges, may be managed with registered Imazapic treatments.

The exact control spectrum must be determined from the applicable product label and locally available field performance information.

Imazapic 240g/L SL Formulation

Imazapic 240g/L SL is a soluble concentrate formulation designation containing a stated concentration of 240 grams of active ingredient per liter.

SL formulations are designed to form a solution when diluted according to the product's instructions.

Commercial specifications should establish the active ingredient concentration, relevant quality parameters, physical and chemical stability, and packaging compatibility.

Importers should request a current product specification and certificate of analysis before placing commercial orders.

Imazapic 97% TC Technical Grade

Imazapic 97% TC refers to technical-grade material containing a nominal active ingredient concentration of 97%.

Technical-grade material is intended primarily for further industrial formulation rather than direct field application.

Formulation manufacturers may use suitable technical-grade material in the development of registered herbicide products.

Before procurement, buyers should verify the assay, impurity profile, analytical methods, and required registration documentation.

Resistance Management

As a Group 2 ALS-inhibiting herbicide, Imazapic must be used carefully to reduce the development and spread of resistant plant populations.

Repeated reliance on herbicides with the same mechanism of action can favor resistance.

An integrated resistance management program should include:

• Rotation with registered herbicides from different mode-of-action groups
• Regular field monitoring
• Appropriate application timing
• Cultural and mechanical control methods where practical
• Avoidance of repeated exclusive reliance on ALS inhibitors

Resistance management is essential for maintaining long-term agricultural productivity and the effectiveness of crop protection products.

Soil Persistence and Crop Rotation

Imazapic can remain biologically active in soil after application.

Persistence is affected by environmental conditions, including soil moisture, soil characteristics, temperature, and microbial activity.

Sensitive rotational crops may be damaged if planted before the required interval.

Therefore, growers should carefully follow product label restrictions for succeeding crops.

Crop rotation planning is especially important in agricultural systems where peanut is followed by other commercial crops.
