HEBEI CHENGNONG BIOTECH CO., LTD. is a leading provider of agricultural solutions, offering high-performance herbicides like the MCPA-isooctyl 85% EC, MCPA 750g/l SL, and MCPA 62% SL. These products are designed to deliver precise and effective weed control in maize fields, ensuring optimal crop health and yield.

Product Overview

The MCPA-based herbicides are selective post-emergence herbicides belonging to the phenoxyacetic acid class. They are formulated in various concentrations to suit different agricultural needs. These herbicides are particularly effective against annual broad-leaved weeds, making them a critical tool for farmers in maintaining crop productivity.

Key Features and Advantages

• High Efficacy: The active ingredient, MCPA, exhibits strong endosmosis conductivity, enabling it to penetrate the cuticle and cell membrane of weeds. This rapid systemic movement ensures the herbicide reaches all parts of the plant, leading to complete desiccation.
• Targeted Control: These herbicides are selective, targeting broad-leaved weeds without harming maize crops. They are effective against a wide range of weeds, including Anticladus heterophyllus, Siderodon heterophyllus, Pigweed, and Wild Rape.
• Easy Application: The product is applied via foliar spray, making it suitable for use during the 3–5 leaf stage of maize and the 2–6 leaf stage of weeds. This timing ensures maximum effectiveness while minimizing crop damage.
• Environmental Safety: Formulated to reduce drift and runoff, these herbicides are designed to be environmentally responsible. They are applied under optimal weather conditions to prevent unintended contamination of surrounding crops or water sources.

Technical Specifications

Product Name	Active Ingredient	Concentration	Formulation	Application Rate
MCPA-isooctyl 85% EC	MCPA	85%	Emulsifiable Concentrate	18–26 ml/mu
MCPA 750g/l SL	MCPA	750g/l	Water Soluble Liquid	18–26 ml/mu
MCPA 62% SL	MCPA	62%	Water Soluble Liquid	18–26 ml/mu

Application Guidelines

The herbicides are applied to the leaves and stems of maize fields during the critical growth stages. The following guidelines ensure optimal results:

• Timing: Apply when maize has 3–5 leaves and weeds have 2–6 leaves. This ensures the herbicide targets the most vulnerable weed stages.
• Weather Conditions: Avoid application on windy or rainy days to prevent drift and runoff.
• Application Method: Use a fine mist spray to cover the target weeds thoroughly. Apply along rows to minimize contact with non-target crops.
• Frequency: Apply only once per growing season to avoid overuse and resistance development.

Storage and Handling

Proper storage and handling are crucial for maintaining the herbicide's efficacy and safety:

• Storage Conditions: Keep in a cool, dry, and well-ventilated area, away from direct sunlight and moisture.
• Transportation: Prevent exposure to extreme temperatures and avoid mixing with food, beverages, or personal items.
• Disposal: Dispose of empty container111s according to local regulations. Do not reuse them for other purposes.
• Precautions: Keep out of reach of children and pregnant/nursing women. Always wear protective gear during application.
