Bunchuk, a.e., (malathion, 500 g/l)

Mechanism of Action and Organophosphate Base

"Bunchuk" is an emulsifiable concentrate containing 500 g/l of malathion. As a classic organophosphate insecticide, it operates primarily through contact action. The malathion molecule acts as a cholinesterase inhibitor: upon entering the pest's system through the cuticle or via ingestion, the substance disrupts nerve impulse transmission, leading to paralysis and rapid death of the insect.

Technical Efficacy in Wheat Crops

The high concentration of the active ingredient makes this product a powerful tool for managing pest complexes in winter wheat. "Bunchuk" demonstrates stable performance against:

• Sunn pest (Eurygaster integriceps), which severely degrades grain quality.
• Cereal leaf beetle (Oulema melanopus), which damages leaf tissue and reduces photosynthetic area.
• Cereal aphids, which sap plant nutrients and promote secondary disease development.

The emulsifiable concentrate formulation ensures high-quality distribution of the working solution across the plant surface, creating a stable protective film upon application.

Application Guidelines

The product is classified under Hazard Class 2, necessitating strict adherence to safety protocols and the use of personal protective equipment during vegetative spraying. Given its contact-based mode of action, the efficacy is highly dependent on spray coverage—the solution must evenly coat the stems and leaves to ensure direct contact with pests. "Bunchuk" is essential for achieving a rapid 'knockdown' effect when pest populations reach the Economic Threshold of Damage (ETD).
