Prefect

Mechanism of Action and Selectivity

The «Prefect» pesticide relies on a synergy of active ingredients, with hexythiazox playing a key role. This component belongs to the mite growth inhibitor group, which affects insect development at early stages. Unlike neurotoxins, hexythiazox blocks embryo development and larval stages, making it a critical tool for controlling spider mite populations in soybeans.

Technical Formulation

The emulsifiable concentrate (EC) formulation is highly stable, ensuring uniform distribution of active ingredients in the spray solution and optimal adhesion to leaf surfaces. Due to its contact action, the solution forms a protective film that maintains efficacy even under exposure to solar ultraviolet radiation.

Practical Application Insights

• Targeted Efficiency: The product is specifically designed to combat spider mites in soybean crops, where stopping the infestation before massive foliage damage occurs is critical.
• Life Cycle Management: The active ingredient inhibits the mite's ability to reproduce, providing a long-lasting protective effect after a single application.
• Ease of Use: With an application rate of 0.2–0.3 l/ha, it integrates efficiently into tank mixes during standard foliar spraying.

Given the 35-day pre-harvest interval, applications must be timed proactively. The manufacturing standards of Jiangsu Fengshan Group and Nanjing Fengshan Chemical ensure high-purity components, which minimizes phytotoxicity provided that the safety protocols for Class 2 hazards are strictly observed.
