Seed Protection Technology: Synergy of Systemic and Contact Action

The efficacy of 'Vispar v.k.s.' is built upon the combination of two active ingredients — thiram and carboxin. This formulation allows for the targeting of pathogens both on the surface of the seed and deep within the embryo, providing comprehensive protection for winter crops (wheat, barley, rapeseed) and corn.

Active Components: Mechanism of Action

• Carboxin (from the oxathiin group) is a systemic fungicide that penetrates the seed kernel. It disrupts the pathogen's cellular respiration, effectively halting the development of smut diseases and root rots as early as the germination stage.
• Thiram is a broad-spectrum contact component. It creates a protective barrier on the seed surface and within the root zone of the soil, suppressing seed mold and helminthosporiosis infections.

The integration of systemic and contact methods offers agronomists a distinct advantage: while carboxin treats hidden internal infections, thiram disinfects the soil surrounding the seed, preventing re-infestation. The formulation—a water-suspension concentrate—ensures excellent adhesion and uniform coverage of the grain without dust formation during treatment.

Practical Implementation

Utilizing 'Vispar v.k.s.' helps avoid crop thinning caused by fusarium and helminthosporium rots. Its systemic action shields the crop during the critical first weeks of vegetation, when the plant is most vulnerable to soil-borne pathogens. The product falls under Hazard Class 2, requiring strict adherence to safety protocols when operating seed treatment machinery.
