Propiconazol en pulverizador de manguera. Derribo curativo rápido y el compañero de rotación adecuado para la azoxistrobina en el manejo de resistencias.
Nuestro Veredicto
Acción curativa más rápida que la azoxistrobina y de una clase química distinta — que es exactamente lo que se busca para la segunda aplicación de una rotación de fungicidas. El envase de manguera cambia precisión por comodidad.
✅ A favor
- Derribo rápido de infecciones activas
- Clase FRAC distinta de la azoxistrobina — compañero de rotación ideal
- El envase de manguera no requiere ningún equipo
- Económico por aplicación
⚠️ En contra
- Ventana de protección más corta (~14 días) que la azoxistrobina
- La aplicación con manguera es imprecisa en días de viento
- La clase DMI puede ralear algunos céspedes a dosis altas de verano

What we found when we read it
Full label read 2026-08-02 on EPA PPLS. Registered product name 'BTF Concentrate'; sold as BioAdvanced Fungus Control for Lawns. Propiconazole 2.42% confirmed. Dollar spot is on this label — nine mentions — along with anthracnose, brown patch, large patch, powdery mildew, red thread, rust and summer patch, which is why dollar-spot.mdx cards this rather than the azoxystrobin granular. Note the same registrant also holds a 0.51% propiconazole GRANULAR product (92564-38); this record is the 2.42% concentrate.
Where this page and the container disagree, the container wins — the label is the legal authority on rates and restrictions. How to read one yourself.
