Type: Fungicide
Mode of Action: Inhibiting sterol demethylation (DMI)
Common Product Names: Quadris Top & Inspire Super
What is it?
Difenoconazole is a triazole fungicide known for its effectiveness against a broad spectrum of fungal pathogens. It is systemic, meaning it can move within the plant tissue, offering protection beyond the point of application. This characteristic makes it particularly valuable in managing fungal diseases that can spread rapidly through crops. Difenoconazole is typically used in low concentrations and is applied as a foliar spray. It has both protective and curative properties, making it a versatile tool in integrated pest management programs. It is especially effective against diseases like leaf spots, rusts, powdery mildew, and various blights.
How does it work?
Upon application, Difenoconazole is absorbed by the plant and translocated through its tissues. By inhibiting ergosterol synthesis in the fungal cell membranes, it disrupts the integrity of these membranes, which are essential for the survival of the fungi. The disruption halts fungal growth and leads to the death of the pathogenic organism. The systemic action of Difenoconazole ensures that even parts of the plant that were not directly sprayed are protected.
