PYREK 25 MC S

Technological Edge: The Microencapsulation Advantage

The efficiency of "PIRINEX 25 MC" by "F.Makhteshim Chemical Works" is rooted in its delivery system: a microencapsulated aqueous suspension. This is a sophisticated engineering solution where the active ingredient, chlorpyrifos, is housed within microscopic polymeric shells. For field operators, this translates into superior residual activity. The capsules protect the active ingredient from rapid degradation caused by ultraviolet light and prevent premature evaporation, ensuring a consistent and prolonged release of the insecticide on the leaf surface.

Contact Action Mechanism

Chlorpyrifos acts as a potent acetylcholinesterase inhibitor. Upon contact with the target pest—ranging from the meadow moth to the cereal leaf beetle—the substance disrupts the nervous system, leading to paralysis and rapid death. Because this is a contact-based insecticide, it remains highly effective even when pests are deep within the crop canopy or hiding beneath leaf tissue, making it a critical tool for perimeter and spot treatments.

Versatility and Field Application

Designed for broad-acre farming, this product is highly effective on a wide variety of crops including winter wheat, winter barley, maize, rapeseed, fodder beet, and alfalfa. It is specifically engineered to target:

• Cereal pests: Cereal flies, cereal leaf beetles, and the Sunn pest (Eurygaster integriceps).
• Foliage and soil-surface pests: Meadow moths, cutworms (Noctuidae), and aphids.
• Migratory swarms: Grasshoppers and locusts.

Application should be performed via foliar spraying during the vegetative stage. Given its Hazard Class 2 rating, proper equipment calibration is essential to achieve a fine, uniform mist. This ensures optimal coverage of the vegetation, maximizing the contact opportunity between the microcapsules and the target pest populations.
