Praktik EC, (diazinon, 600 g/l)

Mechanism of Action and Agronomic Efficiency

The «Praktik EC» preparation is based on diazinon at a concentration of 600 g/l, a classic organophosphorus compound that remains a benchmark in controlling soil-dwelling and hidden pests. Unlike contact pyrethroids, diazinon has a pronounced ability to inhibit the acetylcholinesterase enzyme in the insect's nervous system, leading to irreversible paralysis and death.

Technical Composition Analysis

The emulsifiable concentrate containing 600 g/l ensures a high density of the active ingredient. This solution is critical when working on winter wheat, where pests such as the bread beetle (Zabrus tenebrioides) or cereal flies are often located in the root zone. High concentration allows for optimized working solution consumption rates without compromising biological efficacy.

Application Practice and Protection Spectrum

• Soil Activity: The preparation forms a «protective shield» in the topsoil, which blocks the migration of bread beetle larvae.
• Control of Above-Ground Pests: Effective against adults and larvae of the cereal leaf beetle, as well as leafhoppers, which are vectors of viral diseases.
• Synergy: Due to its Class 2 hazard rating, «Praktik» requires strict adherence to application regulations, but provides the «shock» effect necessary when pest populations are high.

The manufacturer, Sunrise Chemicals Co. Ltd. (Shanghai, China), uses stabilizers in the formulation that prevent rapid degradation of diazinon in the soil solution, extending the period of protective action. Soil treatment using this insecticide is a preventive control method that helps maintain crop density during critical growth stages.
