MCPA-isooctyl 85% EC, MCPA 750g/l SL, and MCPA 62% SL are high-performance agricultural herbicides designed to effectively manage annual broad-leaved weeds in maize fields. These formulations leverage advanced chemical properties to ensure selective and efficient weed control, making them essential tools for modern agriculture. For more information, visit the product page.

Product Overview

MCPA (2-Methyl-4-chlorophenoxyacetic acid) is a selective herbicide belonging to the phenoxyacetic acid family. It is specifically formulated to target broad-leaved weeds while minimizing damage to crops like maize. The three variants—85% EC (Emulsifiable Concentrate), 750g/l SL (Suspension Concentrate), and 62% SL—offer flexibility in application, ensuring optimal performance under varying agricultural conditions. Each formulation is designed to penetrate the plant’s cuticle and cell membrane, rapidly translocating to the weed’s vascular system and causing systemic destruction.

Key Features and Benefits

• High Selectivity: Targets annual broad-leaved weeds without harming maize crops.
• Strong Endosmosis Conductivity: Rapidly penetrates plant tissues and distributes systemically.
• Wide Spectrum Control: Effective against weeds such as Amaranthus, Chenopodium, Pigweed, Ragweed, and Nightshade.
• Easy Application: Suitable for foliar sprays during the critical growth stages of maize.
• Environmental Safety: Formulated to minimize drift and runoff, reducing ecological impact.

Technical Specifications

Product Variant	Active Ingredient	Concentration	Formulation	Application Rate
MCPA-isooctyl 85% EC	MCPA-isooctyl	85%	Emulsifiable Concentrate	18-26 ml/mu
MCPA 750g/l SL	MCPA	750g/l	Suspension Concentrate	18-26 ml/mu
MCPA 62% SL	MCPA	62%	Suspension Concentrate	18-26 ml/mu

Application Scenarios

The herbicides are ideal for use in maize fields during the 3–5 leaf stage of corn or the 2–6 leaf stage of weeds. They are applied via foliar sprays to the stems and leaves of target weeds. Key guidelines include:

• Avoid Drift: Do not spray near sensitive crops like cotton, potatoes, beans, or fruit trees.
• Timing: Apply during calm weather, avoiding windy or rainy days.
• Frequency: Use no more than once per growing season to prevent resistance.

For detailed application instructions, refer to the product guide.

Storage and Transportation

Proper storage is critical to maintaining the efficacy of these herbicides:

• Store in cool, ventilated, and dry areas, away from heat sources.
• Protect from moisture and direct sunlight during transit and storage.
• Keep separate from food, beverages, and personal items.
• Ensure container111s are properly disposed of after use to prevent contamination.
